Anthracnose of Dry Beans - PP1233

Anthracnose of Dry Beans
 
Anthracnose of Dry Beans
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.
