Abstract
Spraying of NSKE 5% @ 2 kg/ha, neem oil @ 2.5 lit/ha and azadirachtin 3000 ppm @ 2.5 lit/ha 20 days after transplanting was most effective against whitefly and leaf miner. Spraying of Bacillus thuringiensis @ 1 kg/ha and azadirachtin 3000 ppm @ 2.5 lit/ha at 45 and 65 days after transplanting showed maximum efficacy against Helicoverpa armigera. Chloropyrifos 20 EC @ 1 lit/ha was most effective against whitefly, leaf miner and fruit borer.
