Abstract:
In the present investigation, an experiment was conducted to test the efficacy of metabolites (culture filtrate) of Trichoderma isolate S₃₂ at different concentrations viz, 100%, 75%, 25%, 10% and 5% on larval mortality and egg hatching of M. graminicola. Among different concentrations, maximum (80%) larval mortality and minimum (18.33%) egg hatching was recorded at 100% concentration after 72 hours of inoculation. Minimum (15.00%) larval mortality and maximum (30%) egg hatching was recorded at 5% concentration whereas, in case of untreated control (5%) larval mortality and (70%) egg hatching was recorded after 72 hours of inoculation.
