Late-Spring Frost Damage to Corn and Soybeans

Early planting may increase yield potential in some years, but it also puts crops at risk for damage caused by early-season or late spring low temperatures.

Are Fungicides Needed On Hail-Damaged Crops?

Recent storms brought rain, severe wind, and hail. With the hail and wind damage that occurred, many growers are wondering if a fungicide application is needed to protect their hail or wind-damaged crops.

Wind Injury in Corn

In the aftermath of severe weather, levels of wind damage in corn can vary greatly from field to field. How plants recover largely depends on wind velocity and corn growth stage.
