In the haste to plant corn, don't neglect to scout for alfalfa weevils. Some light leaf feeding is probably already underway in many southern Illinois fields.
Black Cutworm Moths Have Arrived, Including Northern Illinois Counties

Should I Start Planting Soybeans in April?
Timely soybean planting typically means planting in late April or early May, but the timing has to be coupled with good planting conditions and a favorable weather forecast for maximum yields to be achieved.
