Abstract

Over the last seven years we have added considerably to our knowledge and understanding of the soybean aphid. We know that the presence of the aphid is not enough to warrant the application of an insecticide. Populations below 600 aphids/plant are typically needed before measurable yield loss will occur. Based on several years of replicated field trials, we have developed a recommendation that incorporates an economic threshold of 250 aphids/plant. However, one question remains when it comes to soybean aphid management: What products offer the most consistent control of soybean aphids?
