Abstract

Research on occurrence, incidence and identification of Colletotrichum blight of Jatropha curcas was conducted in Sokoto State of Nigeria. In the survey, diseased leaves were collected from the selected locations in each of the selected Agricultural zones of Sokoto state. Fungal pathogen identified and found to be responsible for the leaf blight in the study areas was Colletotrichum spp. Spores count was made (52328125spores/ml) and pathogenicity trial conducted in the glass house to confirm Kochs postulate. Results from the farmers’ field revealed that Tambuwal Agricultural Zone had the highest incidence and severity of Colletotrichum leaf blight (75.67%). The survey also showed that J. curcas planted in Fadama areas tend to be more prone to the leaf blight particularly those close to water source like streams. It is recommended that; further investigation should be conducted to identify effective fungicides for the management of Colletotrichum foliar blight of Jatropha curcas.
