With the recent hot, dry weather, grasshopper populations are on the rise in parts of North Dakota. According to NDSU Extension’s weekly Crop and Pest Report, outbreaks have been reported in field edges of soybeans, sunflowers and field corn. As cereal grains are harvested, farmers should be aware of grasshopper movement into row crops. NDSU Extension says early detection is critical in preventing yield loss, with economic thresholds set at 21-40 adults per square yard in field margins and 8-14 per square yard in the field interior.
