The integrated effect of intercropping, a synthetic pesticide (monocrotophos) (M) and neem based biopesticide (neem oil – 2%) (NO) on three groundnut defoliators damage and also the groundnut production was studied. The monocrotophos and neem oil combination was found to be very effective in reducing the defoliator infestation. Defoliator’s incidence was significantly higher in untreated plots, resulting in significantly lower yield (1539 kg ha-1). Application of monocrotophos and neem oil mixture increased the groundnut yield (2011 kg ha-1) compared to monocrotophos (1878 kg ha-1) and control categories. The estimated avoidable groundnut and black gram yield loss were lower in monocrotophos treatment.
