Tapley RG, 1964. This process can become laborious, expensive, and destructive to the soil ecology. Colletotrichum kahawae has been shown to produce less disease when shaded by fruit trees, as the fruit trees prevent rainfall from falling on berries, thus preventing dispersal of conidia.

These methods include pruning infected branches, destruction of infected material, removal of mummified berries,[24] minimizing optimal microclimatic conditions for pathogen growth, and the use of competitive and antagonistic microorganisms in the plant phyllosphere. “Root rot disease, rusts, and coffee berry disease can attack healthy trees without any particular physiological weakness, whereas most of the other diseases of economic importance only occur in trees that are physiologically weakened,” it says. Spraying has been determined to be the best way to avoid the coffee berry disease. 1-33. Peter Njogu from Rockbern Coffee, our Kenyan partner, reports a reduced production.
