White mold has become evident in soybeans during the last two weeks, especially in eastern Iowa. Although infection occurred shortly after the beginning of flowering in late June and early July, the characteristic white myecial growth on infected plants has only become apparent the past two weeks. Really the only good news about this disease is that it does not have too much of a secondary disease cycle. In other words the disease itself is no longer spreading or is spreading one plant at a time.
