Ascochyta blight—Ascochyta spp.
Symptoms of plants infected with Ascochyta blight, or fungal leaf spot, include irregularly shaped brown
or purple blotches on leaves or pods. Black lesions can be found on the stems, which may eventually rot
and break. Leaves may shrivel and die.
Solutions
The fungus that causes Ascochyta blight survives in infected plant debris in the soil or on seed. Rain
or overhead irrigation leads to rapid spread. Plant on raised beds so that the soil has good drainage.
Limit the use of overhead sprinklers. Pull up and destroy infected plants as soon as you notice them to
prevent spread in the field. Use pathogen-free seed and rotate out of peas.
