Abstract
Five-day old cultures of Colletotrichum gloeosporioides were more virulent. The, infection increased linearly with the increase in time of exposure to high RH and exposure to high humidity for 72 h was ideal. Oat meal agar was the best medium for sporulation. Conidia produced in this medium showed higher germination and degree of infection. Conidia germination was maximum in tap water as also the degree of infection. Disease development was the highest on 18-day old cocoa seedlings.
