Incidence, development and symptoms of Cercospora disease of coffee in Malawi
The seasonal incidence, development and disease symptoms caused by Cercospora coffeicola on leaves and berries of coffee (Coffea arabica) have been investigated. Disease spread is by wind-borne spores, which are relatively short lived. The fungus overwinters mainly as mycelium in lesions. Spores germinate over a wide range of temperature. Optimum temperature for growth in culture is 25ðC The fungus penetrates the leaves through stomata, and the berries through wounds or sunscorch injury. The alternative host, Ricinus communis, is not important in maintaining the disease in Malawi
