This information was summarized from a June 7 teleconference with ISU extension field specialists in crops.

• Planting of corn and soybean is mostly complete across Iowa. Exceptions are wet fields in the southern two tiers of counties and replanting of ponded or insect-damaged areas in fields. Large hail and heavy rain occurred in spotty locations across the state and may result in additional replanting of storm-damaged crops. Corn growth stage ranges from VE to V7; soybean growth stage ranges from just planted to V2.
• Possible injury caused by the herbicide Balance has been reported across the state (see the Weed Management article in this issue).
• Reports of bean leaf beetle feeding in soybean fields continue, but most fields were not treated because the beetles are not causing economic damage.
• Some replanting continues because of wireworm damage in corn. Some of the fields where wireworms have caused damage were in soybeans last year. Mark Carlton (south central) reported that wireworms and seed rots have caused many acres of corn to be replanted in his area. One producer planted 30,000 seeds and had a 3,000-plant stand.
• 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. Virgil Schmitt (eastern) reported seeing first-generation European corn borer adults in grassy field margins on June 6.
• 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. Joel DeJong (northwest) reported alfalfa weevils on regrowth. 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. Barley yellow dwarf virus is starting to show up (see article in the May 31 ICM newsletter). Brian Lang (northeast) reported three fields with significant smut infestation (from 5 to 20 percent).
