Watersoaked spots appear on leaves and shoots have black stripes.
The leaves at the twig tips wilt and dry up. Some control is obtainable on young trees by pruning dead shoots in autumn and spraying with approved fungicides. The Cercosporella fungus can cause defoliation of older trees. Valuable specimens should be sprayed with approved fungicide if leaf spots are serious. This disease, known only in the southern states, is largely confined to the carpels of the fruit.
