The results obtained in pot and field experiments have shown that Helminthosporium sorokinianum is able to infect bean plants. The cotyledons and roots of shoots during the first three weeks of growth are attacked the most frequently. Dark brown spots occur on the above-mentined organs. The infection of roots and cotyledonsof shoots is responsible for gangrene both before and after germination. Infected plants which remain alive only show symptoms of infection in the root system. The infection of roots by H. sorokinianum in older plants is detromental to growth and causes a decrease in the vield obtained from bean plants
