Abstract
Both the increase in security and extent of coffee berry disease (CRD) during till' II/)OS and the faithful' of Carly-season sprays to control it have been attributed to challenges in climatic conditions and cropping patterns. A critical analysis of rainfall data since 1951, when CBI) first appeared in the East Rift coffee districts of Kenya, produces no evidence that conditions affecting Cll!) development were any different in the 19(,08 than in the 1<)5os, in either higher low-altitude colored-growing areas, . marked increase in overlapping crops occurred during the late II)SOS, and this was caused mainly a change in pruning.: methods. The increased disease hazard from this change of cropping pattern cannot account for the failure of early season sprays, which were success
