Leaf Spot Bananas

Leaf Spot, also known as Yellow Sigatoka, occurs throughout the world and is one of the most destructive diseases of banana. The symptoms first appear as small, light yellow spots or streaks parallel to the side vein of the leaf. Later, the spots elongate and turn brown with light gray centers. Such spots soon enlarge further; the tissue around them turns yellow and dies; and adjacent spots coalesce to form large lesions. The pathogen survives in the infected banana leaves and spreads through wind borne conidia.
