Investigations on coffee berry disease; laboratory studies
A preliminary study of a disease of coffee berries attributed to a form of Colletotrichum coffeanum Noack has been made. By using inoculum obtained from infected detached berries, the disease can be reproduced both in the field and on detached berries in moist chambers. Using these techniques, studies on some host/pathogen relationships are reported. Laboratory tests of various fungicides have yielded results comparable with those of field trials, while three fungicides show some promise of possible control of the disease. Reactions of the host to infection are described. Evidence is put forward in support of the theory that the apparent effect of altitude in limiting epidemic spread is an effect on the susceptibility of the host and not primarily an effect on the pathogen
