The Economics of Insecticide Seed Treatments in Protecting Corn Stands

Erickson, Bruce, Lowenberg-DeBoer, Jess

With escalating seed costs, earlier planting, and more acres in conservation tillage, more and more farmers are looking for ways to ensure their seed investment is protected. Seed and seedling-attacking insects can pose a real threat to the establishment of full, even stands of corn, something that is critical to optimize crop yields. Insect damage can result in stand losses, which lower yields by reducing plant populations, and also by increasing the plant-to-plant spacing variability. Seed treatments, along with soil-applied insecticides and planter box treatments, are used to help protect early stands of corn. At present prices, insecticide seed treatments offer a good value to the producer even when the threat of insect damage is relatively low.
