Black Sigatoka is also known as black leaf streak. The pathogen Mycosphaerella fijiensis causes streaks that
run parallel to the leaves. It is an ascomycete fungus that affects banana trees specifically in tropical
climates; including Asia, West Africa, China, and South America. Tropical weather is the preferred climate
for banana cultivation, but it is also the environment where the pathogen thrives: hot and humid, with plenty
of rainfall to aid in dispersal. The optimal environment of the pathogen is similar to that of the banana tree.
The fungus infects mature banana leaves and will continue to cause infection without proper control. In the
early stages of the infection of the plant, the lesions have a rusty brown appearance and appear to be faint,
paint-like specks on the leaves. They become more visible on the undersides of the banana leaf as the lesions
and leaves grow. The spots on the undersides of leaf are the fungus itself. The sign of the pathogen
consists of the ascocarp which holds the ascospores used for dissemination to infect healthy new plants
when the environment is conducive. The pathogen then survives on dead plant tissue as mycelium. The
dimensions of the lesions are characteristically 20 x 2mm with a well defined wall surrounding it. After
further development, they become darker, sink into the leaf, and turn into depressions. The depressions
themselves and the chlorosis surrounding them are the visible symptoms of the plant pathogen. They
eventually will merge, causing the rapid decline of plant morphological and physiological function.
Leaves with large infectious lesions will start to degrade and collapse because the leaf spots interrupt
the plant's ability to perform photosynthesis, leading to the ultimate death of the plant. The yellow
leaf streak pathogen is in the same genus as that of black leaf streak. Yellow leaf streak shows smaller,
yellow-green lesions that appear on top of the leaves.
