This presentation will help consultants, growers, and other practitioners in the North Central region and other areas where soybean aphid is periodically a problem. It addresses the question of whether the economic threshold for treatment of soybean aphid should be lowered or not in light of current high crop values. By the end of the presentation, viewers should know more about the distinction between an economic injury level and an economic threshold, how the original soybean aphid threshold recommendations were determined, how the information from those studies relates to current threshold recommendations, and why most extension entomologists do not recommend adopting significantly lower thresholds as a cost-effective management approach.
