Damaged stalks face heavy weed competition and will be prone to late-season leaf and stalk diseases. Typically, the best-managed fields are the biggest victims of green snap. Factors that increase green snap also tend to be those that favor high yields. Conventional tilled fields warm up and grow more rapidly than no-till fields, leading to higher green snap risk. High organic matter soils tend to have more incidence of green snap than low organic matter soils.
Hybrids differ in their susceptibility to green snap so plant several different hybrids.
Do not apply growth regulator herbicides to corn beyond the 3-leaf stage. Corn planted at least 2 inches deep is less prone to green snap. Plants with shallow or restricted root systems can have less tolerance to phenoxy herbicides. Investigate crop insurance programs that will give coverage for green snap. Replant options are short at best.
