abstract
A laboratory study was conducted on efficacy of different organics pesticides like commercial neem oil, Dipel Bt, Agniasthra, brahmasatra, Punchapatta, plant extracts against mortality and deformed stages of defoliators of groundnut. A day after spraying Profenophos significantly highest larval mortality (96.67%) was recorded and was statistically superior over all other treatments followed by commercial neem, Agniasthra and commercial Bt formulation which were found at par other by recording uniform per cent of larval mortality (6.67%). The treatments namely Brahamasthra and V. negundo recorded only 3.33 per cent mortality and founds to be at part with each other, while in rest of the treatments including untreated control there was no mortality. The per cent malformed pupa ranged from 0 to 23.33 and the highest being in M. anisopilae followed by sweet flag (20%), Panchapatta (13.33%), GCKE (10%) Agniasthra, V. negundo (6.67% each), commercial Bt and Brahmasthra (3.33% each) and in other treatments no malformed pupa were recorded.
