Open PRAIRIE: Open Public Research Access Institutional Repository and Information Exchange
Abstract
This attacks both leaves and fruits and often also the young twigs. Though the fungus grows on both sides of the leaf it is most conspicuous on the upper surface. It appears as a network of fine greenish brown or blackish filaments and causes the leaves to become discolored, curl up and fall off. On the fruit it produces irregular, dark greenish brown, velvety blotches and while not causing any great amount of decay, hinders growth and deforms the fruit. In very bad cases young fruit shrinks up and falls off
