For last week's ICM newsletter, Michael Uphoff and I wrote an article on management of soybean diseases for specialty soybean. In the article we mentioned that soybean mosaic virus (SMV) can cause seed coat discoloration. This week, the ISU extension staff and a seed dealer reported emergence problems of regular soybean seeds that had SMV-like seed coat mottling. This article will address a few questions that should be useful in preventing such problems.
