Arabica coffee production in Africa is strongly threatened by the attacks of Colletotrichum kahawae, the pathogen of Coffee Berry Disease (CBD) which can cause up to 80% harvest losses (Masaba et al., 1992; Waller et al., 1994). The traditional control of this disease requires 8 to 12 annual applications of fungicide in high-altitude areas (> 1600m) where the disease incidence is high (Bieysse et al., 2002). However, pruning of the coffee-trees and association with fruit trees, generally practised in the small farms, could reduce CBD's epidemics (Mouen Bedimo et al., 2007).
