STRUCTURE AND PHYSIOLOGY
Colonies of Mycosphaerella fijiensis are slow-growing on PDA. They are raised, compact and have a gray to pale-buff velvety surface.
TRANSMISSION AND DISEASE
Mycosphaerella fijiensis causes Black Leaf Streak in banana and plantain plants. It is spread from tree to tree by wind, rain, and irrigation water splashes. It is typically found in low, warm elevations.
DISINFECTION
Fungicides such as benzimidazoles, triazoles, and strobilurins are effective against Mycosphaerella fijiensis infections on plantain and banana plants, but they must be applied frequently to be effective.
UNIQUE OR INTERESTING FACTS
- fijiensis was discovered in Fiji in 1963, but it was likely widespread long before then. Some records suggest it was present in Taiwan as early as 1927.
