University of Minnesota Extension Integrated Pest Management Specialist Bruce Potter advises producers in the southwestern part of the state to be scouting for soybean aphids. He says to only treat if there’s a significant level of population and not just spray on hot spots.
He says while predators are keeping aphids so far from becoming a huge problem they still need to be scouted and managed.
Potter says aphids can cause yield loss and so once they reach a high level they need to be treated.
He says producers can access their extension web site for more specific recommendations at umn.edu.
