Coffee berry disease losses and chemical Control. Sum. no. 18

In Puerto Rico, Coffee Berry Disease (CBD) caused by a complex (Colletotrichum gloeosporioides, Cercospora coffeicola and Fusarium stilboides) is the major disease of production trees. Fresh weight at the same maturity stage is 23.9 percent significantly less for diseased compared to healthy. Similarly, beans dry weight is 19 percent significantly less than those from healthy berries. Coffee losses due to this disease are more obvious when early infections results in mummified, black, weightless berries. From 7 to 40 percent mummified berries have being detected on some farms. On experimental plots at private farms (16 tress/plot, 4 replications) we determined 26 percent (1983, Adjuntas), 30 percent (1983, Maricao) and 51 percent (1984, Lares) mean weight per plot of berries with CBD. During 1984 (Lares), although CBD was reduced by the protectant fungicides chlorothalonil and captafol, disease incidence was too high (31.3 and 31.6 percent, respectively)
