To identify the major pest problems and management practices involved in dry bean production in the region.
Benefits to North Dakota and Minnesota Dry Bean Growers
This survey helps prioritize research needs and provides data needed for preparation of section 18 emergency exemption requests for pesticide use.
A survey was sent to the dry bean growers in the Northarvest production region. The survey asked questions regarding the 2004 growing season. Responses were then returned to NDSU, where they were compiled and statistically analyzed.
A total of 296 responses were received, which represented approximately 22% of the dry bean acreage in the Northarvest region. According to the survey responses, the top three disease problems in 2004 were (in order) white mold, bacterial blights, and root rots. The top three weed problems were nightshade, kochia, and Canada thistle. The top three insect problems were leafhopper, grasshopper, and seed corn maggot. The biggest production problem in 2004, according to the survey responses, was due to adverse weather. Similar to previous years, the most widely-grown pinto, navy, and kidney cultivars were Maverick, Navigator, and Montcalm, respectively.
