Sclerotia of the white-mold fungus is seen inside a soybean stem. White mold was the No. 1 disease problem in 2016 in Wisconsin, especially in more northerly growing areas.

When applying fungicide for white mold in soybeans, the optimal application timing is during the R1-R3 growth stages. Closer to R3 was more effective in 2016.

Sudden Death Syndrome is a relative newcomer as a disease in Wisconsin soybean fields, but in 2016 it plagued growers in southern Wisconsin.

There's a known association of increased severity of Sudden Death Syndrome, such as on these soybeans, and the presence of soybean cyst nematodes in a field.
