Iowa farmers can choose from more than 800 soybean varieties that are described as having resistance to the soybean cyst nematode (SCN). Research results show that the varieties vary greatly in yield and nematode control. The ISU SCN-resistant Soybean Variety Trial Program evaluates hundreds of varieties each year, and results from testing in 2011 are now available.
The effect of foliar fungicides applied on foliar disease, stalk rot and yield of corn were evaluated during the 2011 growing season at six locations in Iowa.
Fungicides, insecticides and fungicide + insecticide applications to soybean were evaluated at six locations across the state during the 2011 growing season.
