Dry bean grower survey in Minnesota and North Dakota: A review of insect pest problems and insecticide use

The dry bean grower survey of varieties grown, pest problems, pesticide use and grower practices has been conducted for 24 years in cooperation with the Northarvest Bean Grower Association, an association of dry edible bean growers in Minnesota and North Dakota. Research and Extension faculty at North Dakota State University and the directors of the Northarvest Bean Grower Association developed the survey and it was mailed out to growers. Participants in the survey were anonymous. In this poster, we will summarize part of the survey’s results on insect pest problems, foliar insecticide use, and insecticide seed treatment use in dry beans for the past ten years. Insects that were reported include:  grasshoppers, potato leafhoppers, bean aphids, wireworms, cutworms, bean leaf beetles, seed corn maggots, spider mites, armyworms and foliage-feeding caterpillars.
