abstract
Field trial was conducted to study and evaluation of nine insecticides and biopesticides (buprofezin 25 SC @ 0.025%, emamectin benzoate 5 SG @ 0.002%, clothianidin 50 WDG @ 0.005%, profenofos 50 EC @ 0.05%, spinetoram 18.5 EC @ 0.016%, dinotefuron 20 WG @ 0.01%, Azadirachtin 10000 ppm @ 3 ml/lit, Lecanicillium lecanii @ 5 g/lit and Metarhizium anisopliae @ 5g/lit) with untreated control.Among different insecticide and biopesticide evaluated, profenofos followed by spinetoram emerged as most effective. The treatment with profenofos 50 EC @ 0.05% recorded highest. i.e. (25.65q/ha)yield of onion with ICBR (1:11.31) as against (16.14q/ha) in untreated control. Whereas, the treatment with spinetoram 18.5 EC @ 0.016%, was found equally effective with this treatment and recorded (24.90 q/ha) yield of onion with (1:2.48) ICBR.
