Kentucky News updated as of November 29, 2007

  • Hello Everyone,

    Below is the final distribution of SBR as of November 29, 2007. As you can see, SBR was eventually detected at an ultra low level in far southwest Ontario and it has also been reported to be active in Mexico. Of course, most of the red on the map of the US is probably not technically accurate. For example, no infected soybeans or kudzu exist in any northern areas, including Kentucky. However, there is still considerable infected kudzu in the South, and perhaps some infected soybean as well. The map will be reset to all white on January 1, 2008 and then we begin again!

    We are now in a waiting game again. How cold will it get, when, and where? Where will SBR survive the winter in the US? What will the spring and early summer weather be like in areas where the disease successfully overwinters? How will SBR activity in Mexico impact us next season? Maybe it won’t. Their seed soybean crop is harvested in our early winter and they don’t plant soybeans again until June. Plus there is very little kudzu to infect in most of Mexico. Jicama, also called yam bean, is produced on small acreages all across Mexico and SBR could build up to substantial levels and blow into the US. As you can see below, Mexican officials are now actively scouting for SBR (mostly yam bean, but also some seed soybean for SBR). Results should be regularly posted on the SBR website (www.sbrusa.net). This information and data from our Mexican friends will be extremely helpful to us, certainly. But interestingly enough, evidence at this time suggests that SBR infections in Mexico may have had their origin in southerly winds originating in the Gulf Coast States around mid-Oct .

    Have a peaceful Holiday season.
