Black Sigatoka

Black Sigatoka is the name popularly given to black leaf streak, the leaf spot disease caused by the fungus Mycosphaerella fijiensis. It is named after the Sigatoka valley in Fiji, where the disease was first reported in 1963. The need to control the fungus to a level that does not affect the export of the fruit makes it the most economically important leaf disease of banana.
