Some farmers in the Minn-Dak Farmers Cooperative in Wahpeton, N.D., and Southern Minnesota Beet Sugar Cooperative at Renville, Minn., were among the first in the country to start using CR+ (Cercospora resistance plus performance) beet seed. The new technology will help prevent big hits from the No. 1 foliar beet leaf disease that in 2016 caused $200 million in losses for the Dakotas and Michigan.
