Small oily spots on leaves enlarge and turn brown and may cause the whole leaf to die. Infected parts of leaves are relatively translucent. Symptoms on the leaf-like bracts of pea plants are often concentrated near the point of attachment to the stem. On pods, oily spots turn brown and may be slightly sunken. Seed may be discolored.
Common, but seldom damaging, except in irrigated crops or very wet seasons, or in fields where hail damage has promoted infection by the bacterium.
