ABSTRACT

The effect of neem cake, insecticides and Trichoderma viride on the infestation of stem weevil Pempherulus affinis (Faust) and incidence of dry root rot Macrophomina phaseolina (Tassi) Goid of cotton was studied. Seed treatment (10 ml/kg) and spray drench with chlorpyriphos 20 EC @ 2.5 ml/lit (15, 30, 45, 60 days after sowing -DAS) combined with soil application of Trichoderma viride (2.5 kg/ha) on 20 DAS were found to be effective in registering the minimum infestation of stem weevil and root rot and maximum seed cotton yield.
