The 2020 dry bean survey is the 31st annual survey of varieties grown, pest problems (insect pests, diseases, weeds), pesticide use, agronomic practices and pest management practices of dry edible bean growers in Minnesota and North Dakota. The survey is supported by the Northarvest Dry Bean Growers Association.

Spray drift from temperature inversions is a major problem for pesticide applicators. This publication is written to help them decide if a spray application should be made or if there is significant potential for spray drift to occur.

This publication summarizes the life cycle, crop damage, and distribution of the banded sunflower moth. It explains monitoring and estimating damage potential, pheromone traps, chemical control and application timing, cultural control, biological control and host plant resistance.

Importance, cause, signs and symptoms, disease cycle and management strategies for clubroot of canola

This publication describes the common arthropod pests of corn in North Dakota. The following pests are included: northern and western corn rootworms, cutworms, European corn borers, grasshoppers, corn aphids, seed corn maggots, spider mites and white grubs (June beetles).

This publication describes the most common natural enemies of insect pests that are found in field crops and gardens. Pictures of each natural enemy are provided for assistance with identification. Predators, parasitoids and entomopathogenic fungi and viral diseases are covered.

This publication summarizes the development of insecticide resistance in soybean aphids in the upper Midwest and how to manage insecticide resistance using an Integrated Pest Management approach.

This guide summarizes the insecticides/miticides registered in North Dakota for control of insect or mite pests of filed crops. Scouting and economic thresholds are listed for the major pest. Keeping in mind that chemical control is only part of an Integrated Pest Management approach. The most effective control may involve integrating culture, host plant resistance and other strategies.

This publication describes two species of gall midges that infest soybeans. Soybean gall midge is an invasive and economic insect pest of soybeans that occurs in five Midwestern states (Iowa, Minnesota, Missouri, Nebraska and South Dakota). It does not occur in North Dakota yet. The white-mold gall midge is native to North America and is not economic insect pest of soybeans. Larvae of the white-mold gall midge can be found feeding on Sclerotinia white mold disease in stems and pods. This publication describes how to scout and identify the two species based on their location on plants, field symptoms and plant injury symptoms. It also tells pest managers what to do if you find any suspect soybean gall midge in your soybean fields in North Dakota.
