Wilting of plants from Rhizoctonia root rot has increased with increasing water stress. First-generation European corn borers are beginning to tunnel into the stalk. Smaller borers are still being found in the whorl. In some cases it is not too late to treat, depending on the size of the borers. Treatment is now complete in many fields that were above the economic threshold.
Grasshoppers continue to increase in number and are prevalent throughout the state.
Most are still small and are found along field edges or in the border rows. Second-cut hay is being made across the state. Potato leafhopper numbers are generally near or above the threshold in many alfalfa fields. Some fields are showing a yellowish tint from hopperburn. Oats are turning and some are being harvested for hay.
