This information was summarized from an April 29 teleconference with Iowa State University extension field crop specialists
- Statewide rainfall was reported during the past week.
- Corn planting ranges from 50 to 70 percent completed in the western and southern counties to 10 to 20 percent completed in the northeastern counties. A few fields are just emerging (stage VE) in the southern half of Iowa.
- Soybean planting has not progressed much from the few fields planted last week.
- Spraying has been problematic in some areas because of windy conditions.
- Alfalfa fields generally are in good-to-excellent condition. Alfalfa weevils were reported in a few locations in southern Iowa, but at populations well below economic thresholds.
- Wheat fields in southern Iowa are between 10 and 14 inches in height and are now jointed.
- Most winter annual weeds are now approaching full bloom, and giant ragweed is up and actively growing.
- Dingy cutworms have been reported in scattered locations around Iowa. See the article in this issue of the ICM newsletter for information on black cutworm and projected dates to start scouting.
