The predicted outcomes for this project are:
i) the best foliar fungicide programs will be determined for frogeye leaf spot, southern stem canker, and target spot;
ii) several races of Phytophthora sojae will be found in Kentucky; and
iii) the effect of seed treatment nematicides on soybean cyst nematode reproduction and soybean yield will be determined.
Since this project will rely on “natural” disease pressure and rainfall, it is possible that disease pressure could be limited in some locations. However, the use of susceptible varieties, when appropriate, will help ensure disease levels great enough to measure efficacy.
