Curing
What Ails Kentuckians
By Randy Weckman
In the United
States Kentucky ranks:
- 8th in
the prevalence of diabetes
- 4th in
death rates for cancer
- 7th in
death rates for heart disease, stroke, and other cardiovascular
diseases
We have met
the enemy and he is us.
That line
from Walt Kellys Pogo comic strip tells us a great deal
about the health of many of us in Kentucky. We are indeed our
own worst enemies when it comes to doing the right things for
our well-being. You might say that many of us in Kentucky are
killing ourselves slowly.
On many, way too many, measures, Kentuckians are among those at
the top of the list of death due tosdue to heart attack,
stroke, diabetes, and some cancers. A new initiative will help
us lower Kentuckys standing in the death due tos by
modifying our lifestyles.
The intent of the Kentucky Health Education Extension Leadership
(HEEL) program is to help us live better and longer. Funded through
an $800,000 grant from the U.S. Department of Agriculture, a partnership
between UKs College of Agriculture and the Kentucky School
of Public Health will educate Kentuckians on how to improve their
health by changing the behaviors that adversely affect healthlike
smoking and eating too much of the wrong things. Sen. Mitch McConnell
led the effort to secure the grant.
In the partnership, the Kentucky School of Public Health will
provide the latest, science-based strategies and technologies
for county Extension agents to use in educating Kentuckians about
healthy lifestyles that help prevent diseases.
County Extension agents have a long and successful history
of providing people with information they need to make their lives
better. The infrastructure of having Extension offices in each
county, coupled with the dedication of Extension agents to teaching
good ideas to people, will assure that information on living longer,
healthier lives will be brought to the people of Kentucky.
said Bonnie Tanner, assistant director for Family and Consumer
Sciences.
It was Tanner, along with Doug Scutchfield, M.D., director of
the Kentucky School of Public Health, who had the idea to link
the Cooperative Extension Service and the Kentucky School of Public
Health to make Kentuckians a healthier lot.
We in Extension have both the infrastructure and the know-how
to bring new information to people where they live, Tanner
said. And the school of public health has the technical expertise
of working with people to help them make vital health-care decisions.
Together, we will help Kentuckians learn to take better care of
themselves.
Healthy Choices
The program, which will begin in July 2002, will work like this:
three health specialiststwo headquartered in the Kentucky
School of Public Health and one at Kentucky State Universityand
10 health educators will work with Extension agents to put educational
programs together to bring health information to the citizens
of Kentucky.
Because lifestyle
choices can a be touchy subjectits hard for people
to listen to lectures about eating way too much for their own
good or not exercising enoughthe program will involve the
expertise of UK sociologist Richard Clayton to teach agents how
to talk with people about changing what sometimes is a lifetime
of unhealthful habits.
For most of us, its okay for someone to talk generally
about lifestyle changes, but when it is about us, personally,
it becomes meddling. Furthermore, its one thing to know
that you need to change your behavior for your own good, butquite
another to implement those changes on a continuing basis,
Clayton said. He also said that making better lifestyle choices
can be tough for many reasons, including our own past.
Genetically, we have the accumulation of thousands of years
working against us. The truth is the selection of genes during
those millennia has yielded a makeup that works great if you are
chasing your food through the plains every day, but not well at
all if you get your daily rations presented to you supersized,
he said.
Clayton sees his role as advising Extension agents on strategies
to make an impact on individuals and ultimately on the health
rates of the entire state.
We can tell people at risk for diabetes, for example, to
monitor their diets and activity levels, but unless we give them
really basic methods such as how to keep records of their activities,
they are likely to remain non-compliant. If we provide them with
the recipe for success in fighting diabetes and other diseases,
they are much more likely to make the lifestyle changes they need
to be healthy, he said.
High Rates,
High Cost
Kentucky stands eighth in the United States in prevalence of diabetes.
It also ranks fourth in the United States and Washington, D.C.
in cancer death rates, with a third more cancer deaths than the
national average. Just last year, 21,000 Kentuckians were diagnosed
with cancer.
Kentucky ranks seventh in the nation in death rates due to heart
disease, stroke, and other cardiovascular diseases. Each day,
43 Kentuckians die from cardiovascular disease.
Why?
Kentucky ranks among the leaders in the nation in the rates for
smoking, obesity, poor nutrition, and inadequate exercise. Each
of these behaviors is related to diabetes, cardiovascular disease,
and cancer.
One estimate is that diabetes alone costs Kentuckians about $1.7
billion each year in medical care costs and loss of productivity.
The most prevalent type of diabetesType 2, formerly known
as adult onset diabetesaccounts for between 90 and 95 percent
of cases and can generally be prevented, and often controlled,
through healthy lifestyle choices. About 180,000 Kentucky adults
(roughly six percent) have been diagnosed with diabetes; another
89,000 have diabetes but havent been diagnosed.
With an increased prevalence of obesity among youngsters, Type
2 diabetes is now being seen increasingly in children.
Type 2 diabetes
is generally caused by a cluster of factors linked to obesity.
A healthful diet coupled with a more active lifestyle can help
prevent Type 2 diabetesand sometimes even control it. The
cost of treatment for one diabetic for one year is about $1,300
in insulin costs alone.
The cost of preventing many of the diseases common in Kentucky
is so much less than caring for people who develop them,
said Dr. Scutchfield. If we were to take the cost of just
diabetes alone in Kentucky and average it across all Kentuckians,
each of us would pay more than $500 per year for it, he
said.
If 10 percent of the current number of Type 2 diabetics were able
to avoid developing the diseaseor were able to control itthrough
exercise and diet, the savings in medical costs would be many
times (212 times) the cost of the
entire program.
Kentuckians
cannot afford not to take better care of themselves, Tanner
said.
The Kentucky
Uglies
But the HEEL
program isnt just about cost effectiveness in health care;
HEEL involves wrestling and whipping what UK President Lee Todd
calls the Kentucky Uglies. Pretty much since he became leader
of the University, President Todd has been talking about marshaling
the universitys talents toward fighting the Kentucky Uglies
(including poverty, poor health care, and illiteracy). Collectively,
these keep many Kentucky families at the low end of the social
spectrum. This program focuses on one of those Kentucky Uglies:
poor health, which affects the others in the Ugly family.
The Kentucky Uglies are an interrelated constellation of factors.
People who dont feel well often have poor work records.
Poor work records manifest themselves in lower incomes, which
in turn affect the ability to seek and pay for medical care. The
cycle is vicious, if not pernicious.
We can help people live healthier, more productive lives.
And if we can do that, maybe can start to eliminate all of the
Kentucky Uglies, Tanner said.
The three
specialists who will lead the Health Education Extension Leadership
program (HEEL) come to the project with solid experience in both
community health and education.
Two of themZaida R. Belendez and Linda A. Jackson Jouridinewill
fill permanently-funded joint faculty positions in the UK College
of Agriculture and the UK College of Medicine. The joint appointment
signals a groundbreaking collaboration between the two colleges
to help Kentuckians improve their health.
A third specialist, Vivian Lasley-Bibbs, will work out of the
Cooperative Extension Program at Kentucky State University as
KSUs arm in the statewide project.
Belendez earned
her bachelors degree from the University of Oregon and her
doctorate in nursing from Case Western Reserve University.
Most recently
Belendez was assistant professor in the UK College of Medicines
Department of Preventive Medicine and Environmental Health and
served as assistant director of Migrant Outreach Programs for
UKs Southeast Center for Agricultural Health and Injury
Prevention. In that capacity she developed programs in health
access for the Kentucky Childrens Health Insurance Program
and outreach to disabled farm workers. Before holding that faculty
position, Belendez was in the Kentuckys Department for Public
Health as a nurse consultant to First Steps, Kentuckys early
childhood intervention system.
Her current
professional interests include developing a way to monitor injuries
to farm workers and a recent application to the Robert Wood Johnson
Foundation for a grant to develop language services in Central
Kentucky.
Jouridine was most recently in the Texas A&M University System
as assistant professor and Extension health specialist for the
Texas Agricultural Extension Service.
In that capacity
she led in development of Extension educational programs on health
and wellness with emphasis on maternal-child and adolescent health.
She provided support to county Extension personnel in developing
programs in areas including infant health, parent education, at-risk
youth, maternal and child health, indoor air quality, and prevention
of drug use.
Jouridine
earned, from James Madison University, her bachelors degree
in psychology and a masters degree in counselor education.
She earned her doctorate in counselor education from the University
of Virginia. She has been a postdoctoral fellow in cardiovascular
epidemiology at Howard University.
Vivian Lasley-Bibbs serves as the state Extension specialist for
health at Kentucky State University, serving as a resource for
county Extension offices. She is currently working with the Black
Community Church Health Project, which is assessing how Kentucky
compares to national figures that show a disparity in the health
care provided to minorities compared to the general population.
Lasley-Bibbs
earned a bachelors degree at Kentucky State University and
a masters degree in public health from the University of
Michigan. She is also a graduate of the physicians assistants
program in the UK College of Allied Health.
She has worked as an epidemiologist for the Department of the
U.S. Army at Walter Reed Army Institute of Research and at UKs
Markey Cancer Center in the Department of Pathology.

The
Value-Added Food Processing Incubator...
Where the
Sage Meets the Sausage
Okay. Youve
got this really terrific idea. Its for a new food product
something that could be even bigger than Kentucky Fried Chicken.
(And get this, youre the next Colonel Sanders.) But ...
how do you put wings on an idea to let it fly?
if its
food, if its a new concept, call Benjy Mikel.
Mikel, an animal scientist at the University of Kentucky Value-Added
Food Processing Incubator, has developed a place where food entrepreneurs
can get solid advice on bringing their new ideas to the marketplace.
What started
in 1997 as a couple of Extension workshops for meat processors
has grown since thenand its growing faster nowinto
a full-fledged, one-stop shop for budding food entrepreneurs.
There they can try out their ideas to see if they really have
the potential for moneymaking before they put their life savings
into them.
The experts
at the incubator work with people and their ideas. First, they
eyeball the idea to see if it has merit for further scrutiny.
If its worthy of proceeding, then they consider the cost
of manufacturing the product, the marketing costs associated with
bringing it to the marketplace, the per-item basis when the production
lines are up and running, and whether the market niche is sufficient
to support the products manufacture.
We let
our clients know at every step of the way what we believe needs
to be done to get the product to the consumer. We act as consultants;
we advise, but the clients make the decisions, said Mikel.
Mikel is a muscle foods specialist in the food science group within
the Department of Animal Sciences whose own brainchild is the
food science incubator program.
The Ultimate
Test: Taste
The team at the incubator even puts new food products through
the litmus test for foods: taste testing.
If it doesnt meet favorably with the consumer palate,
you might as well go home. Consumers are more sophisticated than
ever in their desire for foods. Not only do they want convenience,
they want taste, Mikel said.
Actually, new products go through a two-stage testing procedure
for palatability: first with scientists whose training lends them
some sense of what consumers want, then with real-life consumers.
At the
first stage, our scientists evaluate the product to see if a little
tweaking here and there with spices or other ingredients would
enhance its chances to make it in the marketplace, Mikel
said.
After tweakingand usually several slightly different formulations
come out of that processthe new food formulations are ready
for the real test: consumers.
We have
our taste panels provide detailed information about each of the
formulations of the product, Mikel said.
If the product comes out of taste tasting with high marks, the
team then considers packaging and labeling.
Packaging includes how much product to put in each unit,
which is usually determined by whether the product will be sold
for the wholesale or retail trade, and how to package it for shelf
life and storage ease, Mikel said.
Labeling, he said, is pretty much driven by the federal laws pertaining
to food commerce.
We make sure that the package label meets federal guidelines,
which can be complicated, he said.
The Land-Grant
Philosophy at Work
In its brief life, the incubator has worked with all types of
clients, from Fortune 500 companies to mom-and-pop operations
with hopes of becoming Fortune 500 companies (or at least enticing
the Fortune 500 companies to do business with them).
Each
of our clients has different needs. Small businesses need expertise
at all levels, and we give it to them. They use the whole panoply
of our servicesincluding help from our agricultural economists,
packaging experts, processing people, you name it. The big firms
use our services to help them with product formulation, which
often involves making a quality product with least-cost ingredients,
Mikel said.
Mikel said
that the incubator project embodies the land-grant university
philosophy to a T.
We provide the research and development to the little guys
so they can compete with the big guys. And we are affordable,
he said.
So far, the
services of the incubator remain free to all who ask for help,
although Mikel said that the incubator has benefitted from grateful
clients. We started this with a $150,000 pot of seed money
that Dr. Scott Smith provided (he was then associate dean for
research; hes now dean of the College). From there, clients
have been very generous and we hope that remains the case so we
can grow and become bigger and better. Clients whove used
our services have donated a great deal of expensive equipment
to help us improve our services, he said.
The incubator
program recently became one of the first projects in the state
to be awarded a $75,000 grant through the Kentucky Innovation
Act of 2000, which is designed to help Kentucky businesses create
marketable products from cutting-edge research. The grant will
be used to assist local processors and entrepreneurs in developing
innovative food products.
The Taste
of Success
Mikel is enthusiastic about the entire program, which not only
helps Kentucky farmers and consumers, but helps students in the
food sciences program have real-life experience in food technology
as undergraduates. And that can help them when they seek employment
upon graduation.
The
experiences the students have prepare them very well to take on
responsibilities in industry upon graduation. They know firsthand
how things operate, Mikel said.
The accomplishments
of the program for Kentucky food processors and farmers are impressive.
Several new products already in the marketplace or close to being
in the marketplace, include:
Fried Green
TomatoesMost Southerners relish fried green tomatoes, but
enjoying them is still a late summer treat for home gardeners.
This project links a tomato producer, who produces both field
and hothouse tomatoes, with a major food restaurant chain that
features Southern cuisine.
The Value-Added
Food Processing Incubator has worked with the grower to bread
and freeze the green tomatoes for wholesaling to restaurant chains
that feature comfort food cuisine. Three coating formulationstraditional,
hot and spicy, and cornmealhave been tested at a restaurant.
The outcome is that hot and spicy appeals to younger diners, while
the other two coatings appeal to middle age and older diners.
If the small entrepreneur can secure capital, entrance into the
market is expected within the next year.
Ham Jerky
A small Kentucky pork producer, Foothills Country Meats in Monticello,
wanted to increase the value of pork hams. Working with the incubator
program, the experts suggested ham jerky, a dried meat product
that has long shelf life and a market niche.
Natural ConnectionThe
colleges Food Science program continues to work with businesses
like SMG Inc., which recently purchased Fischer Packing Company
in Louisville. At left is Troy Wilkerson, (UK class of 85,
animal sciences), now SMGs vice president for food safety,
who worked with faculty members Benjy Mikel and Melissa Newman
before they traveled to Field Packing (also an SMG company) in
Owensboro to review its food safety plan. Through its incubator
project, the Food Science program also helped Fischer improve
its natural casing bratwurst.
Did You Know?
Food manufacturing
is one of the states largest manufacturing sub-sectors.
n Food manufacturing accounts for more than 37,000 jobs in Kentucky,
with a payroll in excess of $11 billion annually.
Because of
Kentuckys geographic location (within a days drive
of a substantial portion of the nations consumers) the states
industry has the potential to grow rapidly. n The College of Agricultures
Food Science program, a four-year B.S. degree program, educates
students for positions in the value-added food manufacturing industry.
n Starting salaries for last years crop of graduates were
in the $39,000 range, with hiring demand exceeding the supply.
Taste testing
is an important part of what the Value-Added Food Processing Incubator
does. Scientists on the incubator team do the first taste testing
of the products. Then, after tweaking, real-life consumers try
them out.
Taking Care
of a Sticky Problem
Blend Pak,
a dry blending and packaging plant in Bloomfield, Kentucky, needed
help with a sticky situation. Its breading mixture, used by a
meat packer to coat pork fritters sold at fast food restaurants,
wasnt sticking to some of the meat fritters (which are made
from whole pork loins). It stuck fast on some, but on others the
breading fell off before cooking.
The incubator faculty tackled the problem by first finding out
why the breading only stuck to some pork loin fritters. They found
that the pH of the meats the meat processor used was quite variable,
which accounted for why the breading did the job well for some,
but not others.
We worked with the pork fritter processing company, so they
started using better quality pork loins, which had a more consistent
pH. In addition, we took the advice from the value-added incubator
faculty and modified our coating recipe to include a soybean product
that would increase the breadings adhesiveness, said
Dan Sutherland, owner and chief executive officer of the 25-employee
firm.
We will
continue to depend on UKs incubator to help us with cutting-edge
science research in the future. UKs expertise is just what
small food processing firms like ours need to grow, Sutherland
said.
Putting the
Snap Back into Bratwurst
Bratwurst
aficionados who remember the old-style brats love the newest addition
to the Fischer Meats line of delicatessen products: natural casing
brats.
Until the
middle of the 20th century, brats were made with natural casing
(gut) surrounding the ground porkspiced with ingredients
such as ginger, nutmeg, and corianderthat constituted the
middle of the sausage.
With modern technologyand an industry dominated by large
corporations that could out-compete smaller firms through speed
and efficiencythe natural gut casing became largely a historical
culinary curiosity replaced by synthetic casing.
But many fans
of brats believed that the synthetic casing caused the brats to
lose their snap when they bit into the sausages.
When the Fischer
Meats marketing department saw a market niche for a natural casing
bratwurst, it needed help.
Garry Bork, director of technical services for Fischer Packing
in Louisville, asked Benjy Mikel if the Value-Added Food Processing
Incubator could help redevelop the natural casing
bratwurst to bring back the snap and flavor.
At the incubator, we ground and spiced the pork and stuffed
the natural casings with the mixture. Benjy brought meat sciences
students to help and observe. After we had the uncooked brats
stuffed, we used the smokehouse in the facility to
cook the brats, Bork said.
Because the
natural casings add a distinctive flavor to the brats, the spice
mixture was blended in differentcombinations.
Brats from the different combinations of spices were taste tested
to find the right combinations for consumers, he said.
As a
result of the incubators expertise, we now have a natural
casing bratwurst product the meets consumer expectations. We most
likely will use the expertise of the facility when our sales department
suggests we add another product to our delicatessen line,
Bork said.
Fischers natural casing product can be purchased at major
grocery stores throughout Kentucky, Ohio, Tennessee, and West
Virginia.

The Transformation
of the Ag Library
Where
Have All
the Journals Gone?
By Randy Weckman
First of all,
it isnt on the first floor of Scovell Hall, where it resided
from the early part of the 20th century until 1964; thats
when it moved to the newly-built Agricultural Science Building
(commonly called Ag North). Forget the library paste. There isnt
a pot of it anywhere. And perhaps even more perplexingor
even vexingis the fact that it has no bookswell, hardly
any. Things are so mightily strange that the library is now called
the Agricultural Information Center (although the sign painter
hasnt yet stopped by to change the name over the door).
Our new Agricultural Information Center provides faculty,
students, and staff with most of the same services theyve
always enjoyed. Now, however, we have the room wired with computer
terminals for searches with databases and electronic journals
that are more accessible than hard bound journals ever were,
said Toni (Powell) Greider, agricultural librarian for the past
29 years.
Where are
the books? Journals? The other symbols of a library?
On June 18, 1998, moving van after moving van backed up
to Ag North and carted away our 125,000 volumesgive or take
a few thousand. They are now housed in the new W.T. Young Library,
where they can be used just as always, Greider said.
In their place are the 40-some computers that allow for on-line
searches that are light years faster and more thorough than the
old card catalog. Because these computers take so much less space
than 125,000 volumes of books and journals, the information center
has meeting rooms and even a small video room where patrons can
view educational films. Weve used every bit of space
judiciously, Greider said.
Technology
at Your Service
The technology
of electronic publishing allows users sitting at a computer in
the Agricultural Information Center to tap into a computer at
some other location and find and use current journal articles.
This new library is not like any I ever grew up with. I
was really worried about whether Id be able to use it and
find the information I needed. But the GEN 100 class, required
of all first-year students in the college, introduced me to this
new way of doing library research. And now I wouldnt go
back for anything, said Jason Headrick, a 2002 graduate
in agricultural communications.
The work of
the librarian has changed, too. In addition to collecting, sorting,
and storing important material, the agricultural librarians help
students learn to use the new technology to make their information
searches more fruitful. Greider and five staff members constitute
the library team in the new information center. Their titles reflect
the skills demanded by the new technology, such as electronic
support and those of a webmaster.
And it isnt
just the students who need help to take advantage of the new information
environment; faculty also need help in using the new technology.
Faculty members, too, learned to use a library before it was an
electronic palace; so, along with the students, they needed training
to make the transition to keyboards and monitors from card catalogues
and floor-to-ceiling shelves of books.
Have Suitcase,
Will Teach
And when faculty members have needas many Extension faculty
members dothey can check out a suitcase classroom. The suitcase
is a small soft-sided carrying case that contains a laptop computer,
projection system, VCR, sound system, and lots of accessories,
including a wireless mouse. With suitcase in hand and a telephone
line for Internet access, any classroom becomes wired
to the rest of the world.
These suitcases let faculty and staff members have a 21st
century classroom wherever there is electricity, Greider
said.
Perhaps one
of the biggest changes in the old ag library is that you dont
have to physically step foot in the building to use its services.
We have built our Web site so that people off campus can
use the services of the information center. Click on Information
Center in the left-hand column of the College of Agricultures
home page and go directly to our site, Greider said.
Everyone is
welcome to use the Ag Information Centerstudents, faculty
members, staff, alumni, and
visitors. A click on the Colleges home page on the Web will
take you there.
If there were
really librarians from the past who visit their favorite haunts,
the new Ag Library might put them in a nervous state. Grace Snodgrass,
for instance, who served the Ag Library long and well for more
than 40 years, would find it utterly unrecognizable.

The
Division of Regulatory Services: Protecting and Serving the Commonwealth
By Randy Weckman
If youre
buying pet food for Fido, fertilizer for your lawn, or seeds for
your garden, then your purchases are protected by the Division
of Regulatory Services. You can sleep better at night knowing
that regulatory inspectors and chemists are doing their job to
keep the citizens of the commonwealth healthy.
Secludedalmost
sequesteredon the extreme south side of the University of
Kentucky campus, a small, squarish building houses one of the
most important services for the well-being of Kentuckians. The
College of Agricultures Division of Regulatory Services
assures the citizens of the commonwealth that many of the agricultural
and consumer products they buy are as they are represented on
the label.
In fact, regulatory functions that began more than a century ago
were the primary reason for the Colleges rise to prominence.
They also provided most of its financial resources in those early
years.
It was in the early days of the Progressive Era (Grover Cleveland
was president) that the unit started with only one mancalled
the agricultural chemistperforming the important job of
analyzing fertilizers to make sure that they contained what their
labels purported. The state legislature in 1886 had passed the
fertilizer law, as it was commonly called then and
as it is today. Its real name perhaps provides both the goal and
substance of the bill: An Act to regulate the sale of fertilizers
in this Commonwealth, and to protect the agriculturist in the
purchase and use of the same. In that act, the director
of the Kentucky Agricultural Experiment Station, established a
year earlier at University of Kentucky, would handle the chores
of analyzing fertilizer samples and enforcing the law pertaining
to their labeling.
You see, the 1880s were rife with fraud in a great many things.
Milk routinely was adulterated with embalming fluid to keep it
from souring so quickly; animal feeds contained sawdust to increase
their weight, and bags of seed were stove piped to
increase profits for the sellers (this involved putting a stove
pipe in the middle of the sack, filling the stove pipe with chaff,
with seed only around the stove pipe prior to the pipe being pulled
out). Fertilizers sometimes contained mostly inert ingredients.
Today, the divisions 62 employees not only monitor fertilizers
sold in Kentucky, they also check animal feeds (for both livestock
and pets) for accurate labeling, test seeds sold in the commonwealth
for germination quality, analyze soils for farmers to help them
know how much and what types of fertilizers would increase yields,
and test raw farm milk to make sure that it is marketed accurately.
It is because of the divisions work that consumers are so
well protected today.
Eli Miller, director of Regulatory Services, said about the divisions
work: We dont find too many bad actors these days.
Perhaps our continuous monitoring for fraud dissuades potential
bad actors from trying to hoodwink the public. Today, violations
occur usually because vendors didnt understand the laws
pertaining to their commodity. The vast majority of businesses
that we regulate are extremely ethical and try to sell quality
products. To help them, we do a great deal of vendor education.
Monitoring
Fertilizer Content
Now, more than a century after the first Kentucky fertilizer act,
chemists in the Division of Regulatory Services annually analyze
nearly 3,500 samples of fertilizer submitted from some 950,000
tons of fertilizer sold in Kentucky. These samples are analyzed
to ensure the fertilizer contains what the vendor guarantees on
the label, usually in terms of nitrogen, phosphorus, potassium,
and sometimes chloride levels, and less frequently, secondary
and micro-nutrient composition.
Todays fertilizer analyses are far more comprehensive, accurate,
and speedy than those in the early days. In the 1880s, the agricultural
chemist generally analyzed samples sent to Lexington by farmers
in the state. Each analysis in those early times took several
days to complete. Now, samples are collected by 10 inspectors
throughout Kentuckyusually from manufacturers or mixers
of fertilizersand are analyzed by sophisticated laboratory
equipment in a matter of minutes. And now, fertilizer can be checked
for more than the big three (nitrogen, phosphorus, and potash);
certain samples are monitored for their guarantee of secondary
and micro-nutrients and 10 elements.
The division also inspects specialty (non-farm) fertilizersthose
manufactured for home lawns, gardens, and golf courses, among
othersfor proper labeling and guaranteed nutrients. Samples
are analyzed to help assure that consumers get what they pay for.
Only about 12 percent of the samples we analyze are found
to be less than their guaranteed analysis. In those cases, we
issue a stop sale order, which means that the fertilizer
cannot be sold in Kentucky until it is re-labeled to reflect its
true composition, said David Terry, coordinator of the fertilizer
regulatory program.
The division may impose penalties on manufacturers of mislabeled
fertilizer. The penalties are paid to its purchasers, if they
are known. Otherwise, the money is used by the division to maintain
its operation, Terry said.
Generally, the seller isnt trying to defraud anyone.
Simply, they made a mistake, and they can fix that by re-labeling
their product to reflect the accurate analysis, Terry said.
He noted that to help fertilizer mixers and manufacturers avoid
problems, the fertilizer group in the division holds periodic
educational meetings about how to blend quality fertilizers and
remain in compliance with Kentuckys laws.
Livestock
and Pet Feeds
Because of
the early and profound successes of the fertilizer law, in 1906
the Kentucky legislature added the protection of the states
livestock and poultry producers to the mission of the Agricultural
Experiment Station.
The Kentucky Commercial Feed Law regulates materials offered for
sale as feed or mixing in feed, with exemptions for unprocessed
grain, hay, and silage. In reality, any commercial animal feed
offered for sale in Kentucky must be inspected. Inspection today
covers much more than analysis for the standard nutrients. It
includes checking for antibiotics, ensuring that no prohibited
animal proteins are fed to ruminant animals as a means of preventing
Bovine Spongiform Encephalopathy (Mad Cow Disease), checking that
toxins produced by natural molds are not at harmful levels, and
ensuring that feeds are produced in licensed facilities and are
free from chemical contaminations.
We are on the cusp of a new era in regulation of animal
feeds. I suspect that we in the regulation industry will be called
upon to provide third party certification in the very near future,
said Steve Traylor, coordinator of the animal feed program. Third
party certification refers to tracing the animal from the farm
to the consumer, including the feed the animal ate.
Already, certain
large fast food entities are requiring a history for
all animal products that they use in their foods. By history,
they want to make sure that the animals made into hamburger, for
example, have not been exposed to illegal proteins and antibiotics
and other potential residues.
In the 1930s,
the Kentucky Legislature broadened the scope of the Feed Act to
include the monitoring of pet foods for nutrient content and safety,
probably because an estimated 25 percent of the canned dog food
sold in the United States was consumed by humans, perhaps as an
outcome of financial difficulties associated with the Great Depression.
The law, still in effect today, assures pet owners that the food
they feed to their pets contains what the label says it contains.
Zoos, too, can be assured of the composition of the feed for their
inhabitants.
Milk Inspection
Program
It was the appalling dairy situation in the 1890s that led to
revision of the Kentucky Pure Food Act of 1898, which mandated
that the Agricultural Experiment Station monitor foods for being
pure and unadulterated. The impetus for that law was that much
of what consumers bought was either adulterated or misrepresented,
and sometimes was even unhealthful. Milk was commonly fortified
to keep it from clabbering, cider was made from corn
and burnt sugar, maple syrup was adulterated with
glucose, oleomargarine was sold as butter, and flour sometimes
contained as much as 25 percent cornmeal. In addition, neutral
spirits were colored and flavored and sold as aged straight whiskey
(see related story). The Experiment Stations regulatory
services unit vigorously enforced the law so that the consumers
were infinitely better protected than ever before.
With the reorganization
of the Kentucky Board of Health in 1918, the pure food aspect
of the Experiment Station was transferred to that board, with
the Experiment Station still conducting the analytical, chemical,
and bacteriological examinations for the Board of Health. At the
same time, the Kentucky Legislature added to the Experiment Station
the role of monitoring the weighing and testing of milk and cream,
which was to ensure that farmers were paid accurately for the
amount of milk they sold to manufacturers. (Testing involved determining
the amount of butterfat in each lot of milk a farmer sold; milk
with a high butterfat content was worth more than an equal weight
with less butterfat.) In fulfilling this mission, the division
became responsible for licensing milk handlers, laboratories,
transfer stations, butterfat testers, and haulers.
Our
group maintains integrity in the system from the farm to the processor.
We protect all parties involved in the milk production process,
said Chris Thompson, coordinator of the milk regulatory program.
Seed Inspection
Program
Farmers and
home gardeners alike have great hopes when they plant seeds in
the ground. They hope that the seeds germinate into plants and
that the seeds have little or no weed seed accompanying them.
The Seed Inspection Program randomly selects seed to testfor
both farmers and gardenersto make sure that the label information
is correct concerning germination, pure seed, and estimated amount
of weed seed. The seed laboratory operated by the division also
checks to see how much chaff, dirt, and debris is in the seed,
because that affects the measurement when consumers buy the seed.
If the label isnt correct, the wholesaler or retailer will
need to make modifications on the label.
We also
publish yearly a list of seed vendors whose samples weve
tested, and the results of those tests. Consumers can be assured
that what they purchasewhether it is for their corn field
or sweet corn patchis what the label indicates, said
David Buckingham, coordinator of the program.
Last year,
more than 2,700 samples were taken from seed dealers and consumer
retail outlets, and the seeds were germinated for testing. Sometimes
the composition of the seed package is way off.
Weve had lawn mixes that indicate the package is 80
percent bluegrass and 20 percent fescue; upon analysis, weve
found only 40 percent bluegrass and 60 percent a mixture of other
kinds of seed. Weed seed content is also an occasional problem,
Buckingham said.
Soil Testing
If county
Extension agents are known for any one particular piece of advice
it might be this: Get a soil test.
Soil testschemical analyses of soilsprovide farmers
with precise information about how much nitrogen, potassium, and
phosphorus are available to their crops. If the soil is lower
in soil nutrients than is necessary to grow the best crop possible,
the farmer can elect to add nitrogen, potassium, or phosphorus.
Soil tests also provide information about soil pH and micro-nutrients
that are used by plants, including calcium, magnesium, and zinc.
Soil
test results take some of the guess work out of crop production.
It means that farmers can add to their fields the right blend
of fertilizer they need, said Frank Sikora, coordinator
of the soil testing program.
Soil testing laboratories in Lexington and at the Research and
Education Center at Princeton annually process about 50,000 samples
submitted from across the state.
The soil testing
laboratories also analyze animal waste that can be used to supply
nutrients to crops. This service is increasing as more and more
farmers realize animal manure can be an asset to the farm rather
than a liability.
The Future
Director Miller
foresees the consumer protection and service roles provided by
the division as becoming increasinglyimportant
and necessary.
Food safety and environmental protection especially are
becoming larger issues. Prevention of antibiotic residues and
other potential microbial and chemical contaminants that could
be introduced from feeds will be increasingly expected of us.
Maintaining consumer confidence in the wholesomeness and safety
of milk, meat, and eggs will be a vital part of our program,
Miller said.
In addition,
public concern with the environmental impact of fertilizers will
mean that the division will become more involved with the interface
between fertilizers and soil testing. The seed program will increase
its monitoring of seed for genetic purity and bioengineering,
he said.
Long term, the division will continue to build on the established
programs and services but take on new activities associated with
food safety, environmental protection, and genetic engineering,
Miller said. u
How the Dean
of Agriculture Made Kentucky Whiskey Famous
When the National Pure Food Law enacted in 1906 was before Congress,
Representative A.O. Stanley of Kentucky (later governor of Kentucky)
gave an impassioned, colorful speech describing how grain alcohol
was made inappropriately into a sort of whiskey by adding burnt
sugar and a couple of flavorings. Railing against such so-called
whiskey, he said, It is this sort, made out of this new
alcohol, that will eat the very vitals out of a coyote; it will
make a howling dervish out of an anchorite; it will make a rabbit
walk right up and spit in a bull dogs eye.
Because the
act as passed provided an ambiguous definition of whiskey, it
was left to Theodore Roosevelts attorney general to divine
the true meaning of the term whiskey. Roosevelts counsel
followed the Kentucky definition of whiskeythe real stuff
and not just colored and flavored neutral spirits. But because
politics then as now can be quite fickle, at best, the next president,
William Howard Taft, reversed course and allowed the colored and
flavored alcohol to be sold as whiskey. It is assumed that the
manufacturers of the colored and flavored stuffcommonly
called the rectifiershad made entreaties with Mr. Taft.
Now, Kentuckians,
being wily then, too, knew that federal jurisdiction on the Pure
Food Act did not pertain to intrastate commerce. Precisely because
of this, College of Agriculture Dean Melville Amasa Scovell was
the man to make the decision on what would and what would not
be whiskey in the state of Kentucky. Scovell took a narrow-gauged
definition that whiskey manufactured and sold in Kentucky
would be only that which is the properly distilled spirit
from the properly prepared and properly fermented mash of sound
grain... as distinguished from commercial alcohol, refined alcohol
and neutral spirits. Scovells definition was subsequently
published in the Washington Times, and it is said that because
of Scovells definition, the quality of Kentucky whiskey
became world renowned.
Alas, Scovells definition became moot after 1920 with the
beginning of Prohibition provided by the 18th amendment; nonetheless
Kentuckys reputation for quality whiskey remains unparalleled
to this day.

Research Annual Report
Kentucky
Agricultural Experiment Station
In 1885, the
Kentucky Agricultural Experiment Station began as a place where
scientists showed farmers the best way to grow crops and animals.
It was a big step forward from advice picked up at the local feed
mill or over a neighbors fence.
But today, the Kentucky Agricultural Experiment Station is not
so much a physical place as gathering place for scientists and
their ideas. These scientists work at the Lexington campus, the
Research and Education Center in Princeton, and at Robinson Forest
and Robinson station in southeastern Kentucky.
Some of our scientists come up with answers to Kentuckys
immediate needs. Others are making discoveries that may have impact
only well into the 21st century including those that will
lead to future start-up businesses and become a boon to the commonwealths
economy.
This report will show you the breadth of our work, including the
human dimension that is most evident through the social sciences.
It makes clear that our scientists, whether they work in a lab,
in a farm field, or in a community meeting room, are committed
to serving Kentucky and its people.
Areas of Emphasis
in 2001 include:
- Discovering
new enterprises to support a transition from a tobacco-based
farming economy
- Encouraging
new life science businesses that grow out of scientific discoveries
about how plant and animal genes function
- Conducting
an in-house research program that determined that the eastern
tent caterpillar is the probable source of Mare Reproductive
Loss Syndrome, which caused mares to lose pregnancies during
2001 and 2002
- Improving
the ability of livestock producers to create value-added products
- Strengthening
partnerships with state agencies that promote Kentucky agriculture
Experiment
Station Highlights for 2001:
Generation
of outside funding was more than $14 million more than $10.5
million in College-wide research grants and contracts and more
than $3.8 million in gifts and endowments (which is a 5.8 percent
increase over gifts and endowments in 2000). That means that the
College generated almost one dollar for each dollar the state
contributed. This is significant not only as income, but because
all these sources of outside funding enable us to leverage the
states investment for maximum impact in Kentucky. Other
highlights:
- Approximately
$5.3 million in federal funds
- A 22.5
percent increase in doctoral and masters degrees awarded
over the previous year
- Faculty
publication of 209 original refereed research papers, 38 books
and book chapters, and 166 other articles
- Creation
of a forage animal production unit in partnership with the USDA-Agricultural
Research Service
- Issuing
of two patents by Experiment Station scientists that will result
in new business start-ups in Kentucky
- Forging
of a partnership of the Kentucky Horticulture Council, UKs
New Crop Opportunities Center, and the Kentucky Agricultural
Development Board to discover new opportunities to diversify
the small-to-midsize farm enterprise
- Securing
of federal, state, and private funding to develop new linkages
between local beef producers and their markets
- Discovery
of new opportunities in high-technology agriculture, including
biotechnology, for agribusiness operations of small and midsize
farms

From Coal
to Cattle
In Perry County,
not so long ago, you could look out on what is now a green and
productive cattle enterpriseD & D Ranchand see
the land being mined for coal. The ranch is now home to the East
Kentucky Heifer Development Center, which has become a magnet
for beef cattle producers who want to improve cattle quality and
increase their profits.
This was the site for the largest beef cattle research project
on reclaimed mine land in the country, said UKs David
Ditsch, the projects agronomy advisor.
The center, along with its benefits for beef cattle producers,
is the result of a five-year study to determine what level of
cattle production is sustainable on mined landthe maximum
number of cattle that can be grazed with the land still able to
replenish itself. The answer may have implications for the nearly
1 million acres of reclaimed mine land potentially available in
the eastern part of the state. If all that land were put to pasture
and hay land, it could return nearly $50 million annually to Eastern
Kentucky beef cattle producers.
The heifer development project began in 1994, when members of
two beef cattle associations decided they wanted to improve forage
quality and herd genetics and find innovative ways to market their
cattle. They formed the East Kentucky Beef Cattle Council and
looked to UK agronomists and animal scientists to help them in
their efforts.
The need was clear. Typically weve not had good marketing
opportunities in Eastern Kentucky, Ditsch says. He says
cattle from this part of the state didnt have a good reputation
for quality. When that happens, he says, its difficult
to get good local prices, and it doesnt attract outside
buyers to come in.
A windfall came in the form of 360 acres of reclaimed land from
the Pine Branch Coal Company, leased for an extended period of
time.The
project, which was funded in its first five years by the E.O.
Robinson Trust, initially focused on research, training, and marketing.
Mike Collins, UK livestock forage researcher, regularly collected
soil and plant tissue samples and used geographic positioning
and information systems to create what Ditsch calls revealing
maps. These maps told researchers that if they stocked at
the rate of one cow and her calf for every six acres, the lands
forage quality and animal performance could be sustained.
Workshops
were held for producers on how to increase herd quality. Topics
included herd management and artificial insemination techniques.
As a result of the project, the number of producers coming together
to learn how to manage their heifers and sell their cattle began
to grow.
Working with
project leaders, producers began to use new marketing methods,
including a satellite sale that allowed buyers to see videos of
Eastern Kentucky cattle before placing their long-distance orders.
The heifer development project began in 1998. Producers began
bringing their heifers to the ranch for an 11-month period, where
the animals are developed to sufficient quality and then bred
to high-quality sires. Heifers have to meet certain guidelines
to enter and stay in the program, but when they graduate,
they go with a guarantee of quality, whether they are being sold
or going back to the farm.
In 2000, the
East Kentucky Beef Cattle Council, by then four associations strong,
applied for and received nearly $135,000 in tobacco settlement
money from Kentuckys Agricultural Development Board to expand
the program.
Ditsch says the return on investment has so far been greater than
most producers had previously.
Raising the
Curtain on Convenience
In Kentucky and elsewhere, tobacco was traditionally seeded using
a simple, time-honored method: placing seeds in a seed bed, waiting
for germination, and then transplanting to the field. More recently,
seeds have been placed in plastic foam trays, with the trays floating
on water to provide moisture, then waiting for nature to add sun
and fresh air. Originally the trays were floated in the seedbed
with simple covers such as tarps or plastic, but soon the tobacco
greenhouse was invented to streamline the process and reduce the
vagaries of nature. These greenhouses have roll-up plastic curtains
on greenhouse sidewalls that are cranked up or down to regulate
moisture and temperature inside.
This method has been used for the past decade or so. It requires
the farmer to keep a steady eye on the sky and a constant ear
to the weather report so the curtain can be opened or closed when
necessary. Otherwise, the plants can get too hot or cold and fail
to thrive. And, if too much moisture condenses on the greenhouse
roof, it can cause a drip that washes away the seedsand
potential profits.
Rich Gates
and George Duncan in UKs Department of Biosystems and Agricultural
Engineering have developed a system that controls the curtains
in the greenhouse automatically. The technology, developed in
part with funds from the Council on Burley Tobacco, uses a computerized
motor that closes the curtain when it gets too cold, opens it
when it gets too hot, and lowers the greenhouse temperature even
more at night during certain growth periods to save energy.
Researchers
at UK and the University of New Hampshire are cooperating to take
the automated sidewall curtain technology beyond growing tobacco
to potted nursery plants during winter storage. Because this technique
uses natural ventilation, it has the potential for big savings
in energy costs, and it could have implications for Kentuckys
own thriving nursery industry.
Salad for
Swine
Antibiotics
not only make people well, they keep animals healthy. They have
been a boon to the U.S. animal meat industry since the 1950s,
resulting in healthier animals, shorter time to market, and less
expensive meat for the consumer.
But the use
of antibiotics in livestock production has a downsidethe
bacteria in the gastrointestinal tract of the animals can become
resistant to the antibiotics. There is concern by some people
that bacterial resistance in animals can be transferred to humans,
just as we can build up resistance from taking too many antibiotic
medicines. Any resistanceno matter what the sourcecould
mean drugs wouldnt work as well for us in the future.
Melissa Newman and Gary Cromwell in UKs Department of Animal
Sciences are exploring ways to eliminate or reduce antibiotic-resistant
bacteria in swine.
Newman has
firsthand evidence of how difficult it is to reverse antibiotic
resistance once it is established in a livestock population. For
research purposes, UKs swine herd at Princeton has not been
fed antibiotics for almost 30 years. Several generations later,
bacterial resistance to the antibiotics used in the distant past
still exist in the herd.
Newman began exploring natural compounds and discovered that certain
plant phytochemicals were able to reverse the resistance found
in some bacteria, sort of a salad mix for swine that could reduce
the presence of antibiotic-resistant bacteria. Some
of them are very promising, Newman says. If these compounds
work, we could reduce the presence of the resistant bacteria in
swine, and it would help to calm fears about antibiotic resistance
in humans.
Putting the
Future on Paper
Some Kentucky
counties believe the time has come to manage change instead have
it manage them. They have been spurred on by Lori Garkovich in
UKs Department of Sociology with a process called community
visioning.
It began in 1996, when people in Johnson County decided they needed
a better sense of where the county was going. They also wanted
to expand the number of people involved in community life.
Seven years later, about 15 other communities have also undertaken
a process to explore their future, put their dreams on paper,
and figure out how to make those dreams happen.
Its about civic engagement, democracy in action,
Garkovich says.
First, a local
coordinating group identifies every organization imaginable in
the community, from 4-H clubs to book groups to service groups
like Rotary. Every one of those groups is then contacted and asked
if its members want to take part in creating the community vision.
If they say yes, theyre asked to send someone to training
on how to lead the group through the visioning effort.
The process
boils down to responding to questions on heritage, change, vision,
and action. There are only four questions, but the impact of the
answers can be enormous.
The questions help local visionaries carry what should be cherished
from the past while moving steadilyand with a game planinto
the future.
To get as
many people as possible to take part in the visioning, communities
have outdone themselves. One group set up a tent at the county
fair, offering lemonade and shade. All fair-goers had to do was
sit down and answer a few questions.
Another group
set up posters at a soccer match and encouraged people to scribble
their comments while waiting in line at the concession stand.
One countys local radio station had a regular call-in show.
The shows host posed a question a day to listeners over
several days, who responded by calling in their opinions.
The point is to get as many people as possible talking about
the same four questions at the same time, Garkovich says.
Despite the
hundreds of people taking part in the process in any community,
common themes do emerge, Garkovich says. A major portion of the
report is the recording of every single response by every community
member who participates in the process. Theres power
in that, Garkovich says. Theres magic about
seeing your own words written down.
These reports
are not being tucked away in a drawer somewhere: several communities
have reshaped their land use policies as a result of the visioning.
Garkovich isnt overly concerned about how many Kentucky
counties decide to envision their future. Youre either
ready or youre not, she says. But once the decision
is made, a process to assist communities is available.
Fighting the
Bug from Siberia
In 2000, the
soybean aphid was discovered in Kentucky at only three sites,
and in small numbers. This aphid, naturally found from Siberia
to Iran, had made its way across the Pacific and North America
and onto some of Kentuckys farms. There, if unchecked, it
could injure a good portion of the states soybean crop.
UK entomologist Grayson Brown already knew the soybean aphid can
be a killer. It stunts plant growth by sucking plant sap or, as
a carrier of viruses, kills off the beans. Asian farmers at times
have lost half their soybean crop to this tiny insect. The soybean
aphid can double its population in about three days, creating
swarms so large they have shut down a major league baseball game.
Brown got
to work. By January of 2001, he and his colleagues had obtained
a USDA grant to devise a regional plan to manage the insect. (At
that time, Kentucky was the only state in the Southeast that had
spotted the aphid.) The objective was to come up with an environmentally
and economically sound approach.
The project has been a joint one with the University of Arkansas,
where research on the only disease affecting this aphid is being
done.
Meanwhile,
the soybean aphid kept up its migration. By the 2001 growing season,
a survey of Kentucky soybean fields indicated that, while the
aphid was not yet rampant in the state, it was spreading.
This year, the entomologists are ready. The plan is in place,
and they are already training crop advisors, ag agents, and farmers
in how to use it. This integrated management plan enables farmers
to give environmentally friendly biological controls (including
a type of ladybug, an aphid-killing disease, and stinging wasps)
as much time as possible to work. It also has guidelines for counting
aphid numbers and noting other field conditions that help to signal
if and when costly insecticides are necessary.
Shunning the
Sun
Everybody
knows that its a good idea to use sunscreen if youre
at the beach, out on the farm, or on the ski slope. But sunscreen
for wood?
Absolutely.
So much so that in Jackson at the Department of Forestrys
Wood Utilization Center, researchers are giving various woods
a yearlong suntan, testing about 20 different protective wood
coatings. The project is being carried out in cooperation with
the Forest Products Laboratory at Mississippi State to find out
which formulations work best.
The protective
coatings, which are for wood used on building exteriors, were
developed by various U.S. manufacturers. They are being compared
to products available on the market today.
Kentucky is one of only three sites on the continent where the
testing is being done, says Carroll Fackler, superintendent of
the Wood Utilization Center. Its ideal because the state
has extreme weather conditions, including humidity and heat. Its
also a good site for the fungicide testing of the wood samples
thats also going on. Moisture causes mildew and mold damage
to wood, and, because of its location next to the North Fork of
the Kentucky River, the center gets plenty of both.
In another
project, the center continues to monitor emissions from dry kilns
in Kentucky, which are used to draw moisture out of newly cut
wood before it is treated, processed, and manufactured.
About 500 kilns are at work in Kentucky, making it a substantial
industry in the state.
Recently, as a result of evidence from the kiln study, the U.S.
Environmental Protection Agency chose to exempt those kilns from
standards put in place for air quality. Evidence from the study
had shown that emissions from the kilns were not harmful.
Making Precise
Decisions
Precision
agriculture offers the prospect of detailed field data for cutting
costs and increasing yield and profits. Whats not to like?
Maybe the price tag on the equipment.
Currently,
its not an inexpensive technology to purchase, says
Carl Dillon of UKs Department of Agricultural Economics.
Dillon and collaborators Jean-Marc Gandonou in Agricultural Economics
and Scott Shearer and Tim Stombaugh in Biosystems and Agricultural
Engineering have come up with a way to help producers know if
they should buy or custom hire precision agriculture
equipment. (Custom hiring includes not only equipment rental but
the skill to operate the equipments hardware and software.)
This tool,
as its called in ag economics lingo, gives producers a way
to decide, based on their farm acreage, whether they should buy
or custom hire the equipment needed for precision agriculture.
Using the break-even acreage value, they can know which way to
go. Based on whether a farm is larger or smaller than that acreage
level, the tool will help determine whether to purchase
or custom hire in order to operate in the least expensive way.
To come up
with this tool, the researchers did a partial budget to estimate
the effect of precision agriculture on profits and incorporated
data on equipment ownership, operating expenses, and current custom
hire rates. Then they came up with a mathematical formula that
resulted in a break-even point.
A farmer who
wanted to do field mapping, grid soil sampling, and apply one
fertilizer, for example, would have a break-even point of about
1,000 acres. Farmers with considerably less acreage would likely
want to custom hire since they have less acreage from which to
recoup the fixed cost. Those with more acreage would likely want
to buy the equipment since they have more acreage over which to
spread the fixed cost. Those close to the mark would probably
need to do more analysis.
The break-even
point was figured for other sets of precision ag components as
well as for the package of field mapping, grid soil
sampling, and application of one fertilizer.
Dillon thinks more farmers should consider custom hiring as an
option. Precision agriculture wont make a good manager
out of an average manager, he says, but it has the
potential for increased profits.
An Enemy Becomes
a Friend
Fungal pathogens are a scourge for plants, causing many devastating
diseases. Currently, chemical fungicides provide the most effective
means of control, so the need for biological control, which would
be less costly and more environmentally friendly, would be a breakthrough.
Said Ghabrial
and his research group in UKs Department of Plant Pathology
have discovered an unlikely ally in the battle against these deadly
pathogensviruses. Focusing on the plant disease Victoria
blight of oats as a model system, the researchers have shown that
the fungal causal agent of the disease can be weakened to the
point that it no longer damages the plant.
These UK plant
pathologists have discovered that a virus follows a particular
path to infection: it creates multiple copies of a particular
protein. When the expression of this protein is activated, it
reduces the strength of the fungal pathogens so they lose their
power to destroy plantsif the fungal pathogens were Superman,
the protein would be Kryptonite.
The researchers
predict that if the expression of this protein can be activated
in the Victoria blight fungus and similar proteins can be activated
in other plant pathogenic fungi, this novel approach can be used
to fight fungal infections even when a virus is not present.
They also
have discovered that virus-infected isolates of the Victoria blight
fungus secrete an antifungal protein, which has been shown to
be effective against a wide range of fungal pathogens. The researchers
have been able to isolate the gene that codes for the antifungal
protein and believe that plants modified to include this gene
will have resistance to a broad range of fungal pathogens.
