Abstract
Twenty years ago, less than three percent of soybean planted in Iowa used a seed treatment. As planting dates moved earlier into April, seedling diseases like damping-off were an increased concern, thus fungicide seed treatments were recommended for these early plantings to promote improved stand establishment. Then followed occasional concerns with seedcorn maggot, true white grubs, bean leaf beetle, and soybean aphid to suggest possible benefits with the use of an insecticide seed treatment.
