Abstract

LEAF blights on maize are prevalent, particularly in the forest areas of Southern Nigeria. One of the commonest of these pathogens is Cochliobolus heterostrophus (Dreschl.) Dreschl., already recorded in West Africa in 1928 in Ghana1 and in 1933 in Nigeria2. The lesions develop in abundance on the leaves, from the lower ones upwards. A typically infected maize plant was taken at tasselling time and the area of the various leaves attacked by the fungus determined (Table 1).
