Plant Pathology

The plant pathology program at the NDSU Carrington Research Extension Center conducts agronomy-focused crop disease management research, with a primary emphasis on improving the management of white mold (Sclerotinia stem rot) of soybeans and dry edible beans, Sclerotinia head rot of sunflowers, and root and foliar diseases of chickpeas, lentils, and field peas. The program also conducts work with diseases of safflower, flax, canola, faba beans, and root diseases of wheat.
