Worldwide distribution. A minor disease of bele on older leaves, but important on okra.
Leaf spots, circular to irregular, often limited by the veins, brown with blackish brown margins on the upper leaf surface and pale brown mould below. Sometimes, olive-brown to blackish-brown, indistinct angular leaf blotches occur instead of spots. Severely affected leaves turn yellow, roll, wilt, and fall.
Spread is by spores blown by wind. Survival is in crop debris.
Cultural control: avoid planting new crops next to infected; remove older infected leaves, and burn them; when harvesting young leaves (bele) or fruit (okra);collect and destroy debris after final harvest; crop rotation.
Chemical control: use chlorothalonil, copper or mancozeb.
