the common disease to which the coffee plants are subjected to in india is on account of fungus growth. this fungus is called the "hemileia vastatrix," an endophytous that grows within the matter of the leaf; effective cure has not been discovered to eliminate this. the second type of disease is known as the coffee rot, which has caused severe damages during the rainy season, particularly to plantations in karnataka. "pellicularia koleroga" was the name given to this rot or rust, which turns the leaves into black colour due to the coverage by a slimy gelatinous film. it is now classified as "ceratobasidium noxium" this causes the coffee leaves and the cluster of coffee berries to drop off to the ground. snakes such as cobras can also cause a nuisance to coffee plantations in india.
