Brief Summary of Minutes of Annual Meeting

1. Colorado Potato Beetle Resistance. Rotation of products within the neonicotinoids will not solve resistance problems. Rotations must be with a new class of insecticides. Recommendations include using insecticides as a part of IPM and to include crop rotation; do not follow at planting application with a second neonicotinoid later in the season (Grafius, MI). 2. Breeding programs in the four states focus on screening for resistance to: Common scab, Late Blight, Colorado Potato Beetle (MI); Common Scab, Silver Scurf, Pink Eye (ND); Verticilium Wilt, Common Scab, Early and Late Blight (WI); Late Blight, Verticilium Wilt, PVY expression (MN). Also, 104 clones were evaluated for storage, processing, color, cold chipping, and sugar issues (MN). 3. More than 113,300 seedlings derived from 420 families were evaluated by ND. Unselected materials were made available to CO, MN< TX, MI, and ID. ND 7818-1Y has strong resistance to pink rot, Snowden was very resistant to Pythium leak. Dakota Crisp released by NDSU in 2005 and Dakota Jewel released in 2004. 4. "Healthy Grown" program continues to move forward and is well received by the growers and industry (WI).
