By the middle of June, all Iowa corn had emerged compared with 95 percent emergence at this time last year and 99 percent on average. Crop spraying was constrained because of strong winds in most of the state. Also, scattered heavy rain and hail in central and northeast Iowa resulted in isolated reports of crop damage during the third week of June. As of June 24, the crop conditions remained stable, with 79 percent of the corn in good to excellent condition and only 4 percent rated poor to very poor. For soybeans, planting is ahead of normal and was completed in the middle of June compared with 90 percent planted this time last year. By the end of the month, almost all soybean acreage had emerged, with 75 percent of the crop rated good to excellent and only 4 percent in the poor and very poor categories.
