Diseases designated anthracnose are characterized by distinctive dead areas on leaves, often along the veins, on stems or fruit. Small, slimy, pinkish spore pustules are formed in wet weather. The slime spores are spread by wind-blown rain, or by man handling wet plants, but they are not blown about in dry weather. Hence anthracnose diseases are most serious in unusually rainy seasons.

(Colletotrichum lindemuthianum), sometimes incorrectly called rust, the major bean disease in eastern and central states. Dark areas form along veins on underside of leaves and on petioles, reddish brown spots on stems of seedlings. Chief symptoms are on pods: round, dark, sunken spots with reddish brown borders, pink spore masses in center in wet weather. If pods are infected when young, the disease extends through to the seed, producing a spot first yellow, then rusty brown or black.

Control. Use western-grown seed and choose relatively resistant varieties; do not save home-grown seed. Do not pick or cultivate beans when plants are wet; clean up or turn under all old tops.
