Observations on the Epidemiological Peculiarities of Cocoa Pod Rot Pathogens
(1978) Adebayo, A.A.
Phytoph thora, fusarial and charcoal rots are three major pod diseases of cocoa in Nigeria. Usually, a diseased pod carries one or the other or even a combination of the three diseases at a time. Since the three diseases are caused by different pathogens it is to be expected that eaoh will have its peculiarities. Results of field observations in two widely separated cocoa crowing areas of Nigeria (Gambari Experimenta:l Station, Ibadan and Ibule near Atkure) are reported. There are indications that while Phytophthora pod rot has rainy season epidemi,cs, fusaria rot and especially charcoal rot are dry season diseases. Whole resistance of pods to Phytophthora pod rot disease decreases with the age of pods, mature pods are definitely more tolerant to fusarial and charcoal pod rots than cherelles.
