| Abstract: | The incidence of maize cob rot caused by Stenocarpella maydis, S. macrospora, Fusarium moniliforme, F. subglutinans and F. graminearum was determined over two seasons under different tillage systems at various localities. Tillage had no effect on Fusarium spp. cob rots. S. macrospora occurred only at one locality, viz. Cedara, and no tillage effect was observed. Ploughing reduced the incidence of S. maydis cob rot at localities which had high incidences of disease. The relationship between severity of S. maydis cob rot and surface stubble mass was linear. |
