Pesticides are the typical go-to tool for controlling soybean aphids, but that shouldn’t be the only thing farmers use. University of Minnesota Extension Entomologist Robert Koch says biological control is also important along with host plant resistance, the use of pest resistant crops. “These aphid-resistant varieties can be very effective for soybean aphid,” explains Koch. “However, the availability of well-adapted resistant varieties is low. There’s lots of work going on to increase availability.” Koch was part of the Best of the Best in Wheat and Soybean Research and Marketing in Grand Forks.
