Sumario: | This work was carried out on a grain sorghum crop (Sorghum bicolor (L.) Moench) cv. Frontier 4122 sowed according to a experimental design in split plots with four replications. The principal fungi associated with sta'k rot in natural infections belong to the Fusarium spp. group, being the most important F. moniliforme Sheldon; Macrophomina phaseoli (Maublanc) Ashby, Nigrospora sp. and Helminthosporum sp. were present very few times. Heavy rains during the growing season followed by dry conditions close to riping point helped stalk rot. The incidence of disease was notably reduced under either minimum tillage or zero tillage practices as compared to conventional tillage when early tilled soil was not carried out; when it was performed the incidence of disease highly decreased under minimum tillage compared with conventional and zero tillages. |
