Abstract
The influence of Busseola fusca incidence and damage on Fusarium moniliforme and Stenocarpella maydis ear rots was studied in the field using artificial infestation with B. fusca, mechanical damage and pathogen inoculation. B. fusca infestation increased the incidence of F. moniliforme infected maize ears irrespective of artificial or natural F. moniliforme infection. Mechanical damage plus F. moniliforme inoculum also resulted in a high incidence of F. moniliforme-infected ears suggesting that physical damage to the ear will increase F. moniliforme-infected ears. Fungus-infected rotten kernel percentages of B. fusca-damaged treatments did not differ significantly from the control. The insignificant correlation (r = −0.206; P = 0.695) between F. moniliforme- infected ears and per cent rotten kernels indicates that in the case of the former, when used as a disease criterion, damage was localized and did not result in significant grain quality reductions. Neither B. fusca nor physical damage significantly affected the incidence of S. maydis-infected ears or rotten kernels. Therefore, under the conditions of this study, the control of B. fusca will not result in significant grain quality improvement.
