Abstract
Bock (1963) showed that in the years 1956--60 early season sprays achieved good control of coffee berry disease (CBD) in East Rift areas of Kenya. In recent years, however, this spray programme has "given erratic and often very poor results. In field experiment in 1966 yields of main (late) crop were increased from 151 to 652 kg/ha b){early season sprays but in 1967 practically no control of the disease was achived. Of the fungicides examined captafol was superior to copper; 'Tuzet', 1ihe best antisporulant, gave the poorest control. Analysis of the data indicate that this large seasonal variation depends on the very different interrelationships between rainfall, cropping pattern and timing of sprays which obtained in the 2 years..
