Insecticide-resistant soybean aphids have emerged as a new challenge to farmers throughout the upper Midwest. Iowa State University Extension has released a new regional publication with management strategies. A wide variety of recommendations are covered, including economic thresholds, insecticide efficacy and field retreatment. Research from faculty at ISU, the University of Minnesota, North Dakota State University and South Dakota State University is included. The publication is available through the ISU Extension store.
