This information was summarized from a May 17 teleconference with ISU extension field specialists in crops.

• Planting progress was slowed this past week because of scattered rainfall that occurred in many areas of the state. Producers made the most progress in the northeastern, north central, northwestern, and southwestern areas.
• Heavy rains and damaging winds occurred May 16, especially in the northeastern counties, where from 1.5 to 15 inches of rainfall was reported by Brian Lang and George Cummins. Flooding was the most severe along Highway 3 and in parts of Fayette and Clayton counties. Tony Weis (northwest) and John Holmes (north central) reported heavy rain and some twisters. Along with the heavy rains, sheet erosion and damage to terraces was reported.
• There were several reports of wireworm damage. Mark Carlton (southeast) reported 2-4 wireworms in a baited trap in a cornfield that is in its second year out of CRP. Mark also reported a field with flea beetles feeding on corn.
• If weather conditions cooperate, alfalfa harvest will continue this week. Some alfalfa that was cut last week was damaged by rain. Mark Carlton (southeast) reported alfalfa weevil above the economic threshold in one field in Appanoose County. (See Marlin Rice's article in the April 26 ICM newsletter). Reports of leaf diseases on alfalfa continue (see Gary Munkvold's article in the May 17 ICM newsletter).
• Winter annuals have become a problem in some fields that are too wet to plant.
• The table gives estimates of the percentages of corn and soybean planted, reported by field specialists' area of the state. Up to 75 percent of corn has emerged in some areas, whereas very few soybeans are up. Because of rainfall patterns and wet soil conditions, the ranges for planting in some areas of the state are variable.
