Kentucky News updated as of September 14 , 2007

• Hello Everyone,
  
  Soybean rust (SBR) continues to be detected at low levels in new locations in Arkansas. Yesterday (September 13) SBR was reported on soybean from the two counties circled on the map below. The find in northeast Arkansas, and other recent finds in that state, are probably the result of SBR spore deposition and infection that occurred in late August as the remnants of Tropical Storm Erin blew through the region. The second map shows the output of what is called an SBR ensemble model, which in the simplest terms is the SBR forecast based on the overall finding when three different SBR models are run. This same type of thing is commonly done with weather forecasts, but many more models are used. In any event, you can see that on August 22 when peak SBR spore spread and possible infection occurred, the model indicated that states west and north of Kentucky were potentially impacted, but that Kentucky was missed almost entirely. I have been saying that if anyone in the state DID get any rain from that system, that they might be able to find soybean rust at this time. However, I know for a fact that most of the central and western part of the state remained hot and dry throughout late August. If we see soybean rust in west and central Kentucky this year (and I believe we will), it will probably be as a result of the multi-day front that brought rain to much of the state during Sept 7-10. We won’t see evidence of any infections associated with that system until mid to late September.
  
  I would say that no matter what happens during the rest of the season, our soybean crop is too far advanced in stage to have any yield impact due to soybean rust. A few fields here and there may still be as some risk, but they are few and far between.
