Abstract
Studies on the incidence of stem canker of cocoa caused by Phytophthora palmivora (Butt.) Butt, under different cropping systems revealed that the incidence and severity of the disease varied with cropping systems as well as with locality. The disease incidence was the highest in cocoa-forest plantation followed by cocoa-areca mixed cropping system. Based on the point of infection, the affected trees were classified into those with collat, trunk and branch cankers. The highest number of canker lesions were observed on the main trunk. The affected trees were also classified on the basis of severity of infection by measuring the lesion size.
