Sharma, Monika | Sharma, Duni Chand
The efficacy of six biopesticides viz., melia (Melia 10 EC), eupatorium (Eupatorium 10 EC), melia-SFE (Melia-SFE 5 EC), eupatorium-SFE (Eupatorium-SFE 5 EC), azadirachtin (Neem Baan 1500 ppm), spinosad (Success 2.5% SC) and one synthetic insecticide malathion (Milthion 50 EC) against mustard aphid (Lipaphis erysimi Kaltenbach) and leaf miner (Chromatomyia horticola Goureau in brown sarson is reported. On the basis of reduction in insect population over control on 7ᵗʰ day after spray, the order of efficacy against L. erysimi was malathion > azadirachtin = melia > melia-SFE = eupatorium > eupatorium-SFE > spinosad and against C. horticola, spinosad > melia = melia-SFE = malathion > azadirachtin = eupatorium = eupatorium-SFE. Malathion, azadirachtin and melia treatments resulted in significantly higher yield as compared to untreated check.
