Abundant rainfall and cooler soil temperatures early in the season will increase the risk to seedling diseases and stand loss; especially in cotton.
Growers can reduce the risk to seedling diseases by a) delaying planting until conditions (warmer soils, less threat of a cold, drenching rain) are more favorable for rapid germination and vigorous growth and b) use of fungicide seed treatments to protect the seed and the young seedlings.
Corn growers who plant in late March or early April have less risk to disease than do those who plant in later April and beyond. Growers with increased risk to Northern corn leaf blight (e.g., a more susceptible corn hybrid) should scout their crop and consider a fungicide application prior to tasseling; for example between the V8 and V10 stage. It may be possible to use ground equipment to accomplish this. NOTE: DO NOT MIX a surfactant or crop oil with the fungicide when applied prior to tassel in order to reduce chance for injury to the developing ear.
