Mostly minor infestations of black cutworms were reported so far, except in western Iowa. Several fields were treated in Harrison and Monona counties. Some fields were replanted. Stalk borers are beginning to move into cornfields from grassy areas. Most of the first-cut alfalfa is harvested, except in the southern third of the state, where only about 50 percent of the alfalfa harvest is complete.
Alfalfa weevils are a problem in some uncut fields.
Potato leafhoppers are being reported on alfalfa and they are starting to reach or surpass the threshold in some fields. In general small grains are looking good. Oats and barley are beginning to head. This information subject to a usage policy .
