Soybean samples have been arriving almost daily at the ISU Plant and Insect Diagnostic Clinic this year. Early season problems were primarily damping off diseases and problems with herbicide carryover or sometimes a combination of the two.

With the harvest underway throughout Iowa, rain in some parts of the state is stopping combines from securing kernels from the field. Depending on your location, disease pressure might not have been high. However, rainfall patterns  throughout the season, and even over the last several weeks, means we are not out of the woods yet. Ear rots and associated mycotoxins could be problematic as corn sits in the field awaiting harvest.
