Only the fourth group was able to infect both wounded and unwounded green berries and was formerly referred to as C. Fruit is attacked in all stages, and total destruction of the crop can be caused. Currently, however, the disease is only prevalent in areas Africa at high elevations and with high relative humidity. The role of saprophytic surface micrflora in the development of coffee berry disease, Colletotrichum coffeanum, in Kenya. that are isolated from coffee plants, four groups were initially described based on their morphological traits: CCM (C. coffeanum mycelial), CCA (C. coffeanum acervuli), CCP (C. coffeanum pink) and the Coffee berry disease (CBD) strain.  Soon after, the fungus has quickly spread throughout most of the African continent, being reported in Angola (1930), Democratic Republic of the Congo (1938), Cameroon (1955), Tanzania (1964), Ethiopia (1971), Malawi and Zimbabwe (1985), and eventually most of the Arabic coffee areas in the continent were affected. The disease was first recorded in Uganda in 1959 and surveys on the disease indicated that up to 50% crop losses were being incurred. Quadris is active against the following diseases in coffee: Coffee Berry Disease(Colletotrichum kahawae) and Coffee Leaf Rust (Hemileia vastatrix) Enhances the crop's ability to uptake Nitrogen leading to bigger produce.  Several authors attempted to emend this anomaly but it was not until 1993 that Waller and Bridge described C. kahawae as the causal agent of CBD and as a distinct species based on morphological, cultural and biochemical characters and more recently on multi-locus datasets.

Fruit dropping from plants; small holes may be evident on red cherries; when the insect is feeding, debris is pushed out of the hole and forms a brown or grey deposit on top of the hole; adult beetle can be found by cutting open the berry; adult is a tiny black beetle approx. 19. L'anthracnose de baies du café d'arabie, Coffea arabica. 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, minimizing optimal microclimatic conditions for pathogen growth, and the use of competitive and antagonistic microorganisms in the plant phyllosphere. Muller RA, 1973. The spores are covered in a gelatinous coat which expands under wet conditions to facilitate in spore dispersal during rain.
