Black Sigatoka is also known as Black Leaf Streak, and is found mostly on the banana crop. The pathogen is Mycosphaerella fijiensis. The lesions start off looking rusty brown and they appear to be faint, paint-like specks on the leaves. After further development, they become darker, sink into the leaf, and turn into depressions. Leaves with a large infectious lesions will lead to the ultimate death of the plant.
