Dry Edible Bean Rust - PP1601
Between 1996 and 2008, bean varieties with resistance to rust made the threat of a bean rust epidemic in North Dakota very low. However, in 2008 a new race of the pathogen was identified in North Dakota. The new race has the ability to cause disease on the only commonly used effective resistance gene in common varieties. In 2010, the new race spread throughout North Dakota and into northwestern Minnesota. With the spread of the new race, the region is at risk again for the multimillion dollar yield losses caused by bean rust decades ago.

Anthracnose of Dry Beans - PP1233
Anthracnose is an economically damaging disease of dry beans that can cause significant levels of seed discoloration and large reductions in yield. The disease is readily transmitted from infected seed to seedlings, which will result in fieldwide epidemics that can spread to nearby fields when the environment is favorable for infection and spread. Because infected seed is not always discolored, the use of certified disease-free seed is critical for management of anthracnose. Further, the disease is difficult to control with foliar fungicides and seed treatments, and the pathogen can develop new races that overcome genetic resistance, making prevention the best disease management strategy.

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. Recent discoveries of the sexual stage of the powdery mildew fungus in several sugar beet producing states could lead to potential biological changes in the fungus, making it more difficult to control.
