Abstract:
Investigations on evaluation of integrated pest management module in groundnut was carried out at Oilseeds Research Station, Latur, Maharashtra during Rabi, 2020. Evaluation of integrated pests management module in groundnut including application of azadirachtin as bioinsecticides, hand collection of larvae & egg masses of defoliators and installation of pheromones traps, yellow sticky traps, Soybean & Castor as a trap crop for defoliators. IPM module was significantly superior in reducing the incidence of sucking pests i.e. aphids, leafhoppers, thrips and whiteflies due to installation of yellow sticky trap and spraying the crop with biopesticides at early stage of crop growth. Defoliators population and its damage was also control by installation of pheromone traps to catch the moths of lepidopterans pests and also spraying the crop with biopesticides at early stage of crop growth, enhancing the population of predators and pod yield of groundnut. It is observed that sucking & lepidopterans pests population before spray was statistically non-significant in IPM module plot. The pests population was significantly reduced one, three, seven and ten days after spraying in IPM module as compared to the farmers practice plot. Yield of groundnut pods obtained from farmers practice and IPM module plots was 1326.07 kg pods/ha and 1797.64 kg pods/ha respectively. The avoidable yield losses observed due to pest were 471 kg pods/ha. The per cent reduction in the yield due to pests was computed as 10.82 per cent. The incremental cost-benefit ratio (ICBR = 1:6.78) was recorded from farmers practice and IPM module plots.
