We conducted a survey of 1999 dry bean production problems and practices at the Northarvest Bean Day in January 2000.  The information producers gave us helped direct research and support pesticide registration applications.  Results are summarized below.

Classes of Beans: Pinto beans were planted on 45% of acres in 1999, followed by navy beans on 31%, kidney on 13%, black on 7% and pink on 3%. The percentage of navy acres in 1999 was twice that in 1998 and the percentage of black bean acreage in 1999 was half that in 1998.

Leading Pinto Variety: Maverick continued as the leading pinto variety, with 56% of pinto acres in 1999, compared to 43% in 1998. 

Chase, Frontier, Maverick, Remington and Winchester are all resistant to current rust races. They were planted on 81% of pinto acres. Use of rust fungicides declined in 1998 and again in 1999 as an increasing percentage of pinto acres was planted to rust resistant varieties.

Leading Navy Variety: Norstar continued as the leading navy variety, planted on 37% of respondents navy acres in 1999.  Vista and Mayflower were each planted on 12% of navy acres.

Worst Production Problem: Weather was the worst production problem in Minnesota.  Harvest was the worst production problem in North Dakota.

Worst Disease: Root rot was again the worst disease in Minnesota and white mold was again the worst disease in North Dakota. White mold fungicides were used on 26% of Northarvest acres, double the percentage in 1998.  In contrast, rust fungicides were used on only 3%.

Worst Weed: Nightshade continued as the worst weed in North Dakota, and ragweed was one of the three worst weeds on 22% of respondents acres. Ragweed was the worst weed in Minnesota and nightshade was second, down from first in 1998.  Richard Zollinger used the data to obtain a section 18 for Reflex for ragweed control and a section 18 for Raptor to control nightshade.

Worst Insect: Leafhopper was the worst insect problem on 40% of Northarvest acres.  Asana was used on 7% of acres.

Rotation Practices: Dry beans followed wheat on 64% of North Dakota dry bean acres.  In Minnesota, dry beans followed wheat on 40% and corn on 35% of dry bean acres. Crop rotations in North Dakota were most commonly 2-5 years, and in Minnesota they were most commonly 3-5 years.
