摘要：A study was carried out at S. V. Agricultural College, Tirupati to evaluate the efficacy of selected insecticide molecules against pod borer complex in field bean during rabi, 2020-21. The results revealed that among nine insecticide molecules tested for their efficacy against major pod borers, the sprays of spinosad 45 SC @ 0.3 ml/L were found to be most effective against spotted pod borer (82.26 per cent reduction over control), tobacco caterpillar (79.77%), blue butterfly (81.13%) and pea pod borer (81.14%). The next in the order of efficacy were indoxacarb 14.5 SC @ 0.5 ml/L which has recorded 80.45 per cent reduction over control for spotted pod borer, 78.82% for tobacco caterpillar, 79.93% for blue butterfly and 79.79% for pea pod borer whereas flubendiamide 20 WG @ 0.3 g/L has recorded 81.02 per cent reduction over control for spotted pod borer, 77.13% for tobacco caterpillar, 77.41% for blue butterfly and 77.11% for pea pod borer. Similarly, the least per cent pod damage was observed in spinosad @ 0.3 ml/L (37.10%), indoxacarb @ 0.5 ml/L (37.45%) and flubendiamide @ 0.3 g/L (37.98%) which were statistically on par with each other. The results on the effect of pod borer complex management on yield revealed that, among the treatments the pod yield was maximum in spinosad 45 SC @ 0.3 ml/L (1347 kg ha-1) followed by indoxacarb 14.5 SC @ 0.5 ml/L (1278 kg ha-1) and both the treatments were at par with each other.
