Unfortunately, corn is the crop that produces the highest net income per acre in most seasons within our region. Fortunately we still have not seen signs of root rots in soybeans. The potential for leaf diseases is also high. The root diseases most likely to occur under conditions of wet soils and cool temperatures are phytopthora root rot, pythium diseases, and brown stem rot. Phytopthora can occur any time during the season, but is most common before pod set so this is the disease I am watching for most closely.
Soybeans remain off color due to high soil moisture levels.
Many bean fields have active nodules at this point in the season. We just need warmer, drier weather to move the crop along. Corn taller than 20 inches is being affected by european corn borer. Most of the yield loss is the result of damaged stalk and nutrient flow within the plant. Scouting for corn borer damage is complicated.
