The etiology of fruit anthracnose in hot pepper (Capsicum frutescens) was investigated at Ibadan, Osogbo, and Ikenne in the lowland forest zone of western Nigeria. Collectotrichum capsici (Synd) Butler & Bisby was found associated with the fruit anthracnose of hot pepper in all locations. Out of 300 plants examined in all the locations, over 70 per cent had fruit anthracnose, while in some pepper fields all the fruits produced had the disease symptom. The pathogen overseasoned in pepper plant debris. A high inoculum population of 4.9×106 g−1 colony forming units/g was estimated in the soil of pepper fields. The seed from the infected hot pepper fruits also carried propergules of the pathogen. The fungus was also found on Lycopersicon esculentus, C. annum and Vigna unguiculata growing in and around the pepper fields. Pepper fruits infection by the disease occurs during the peak of the rainy season beginning in patches which spread later, resulting in extensive infection of the pepper field.
