Sugar Beet Powdery Mildew - PP967
Powdery mildew is a sporadic fungal leaf disease of sugar beet in the Red River Valley and southern Minnesota sugar beet-production areas. It first was found in Minnesota and North Dakota in 1975. In recent years, the use of triazole and strobilurin fungicides for Cercospora leaf spot control has limited powdery mildew development.
