abstract
A field experiment was conducted at a field of Entomology section, College of Agriculture, Nagpur (Maharashtra), India during kharif season of the year 2018-2019. The bio- efficacy of eight newer insecticidal molecules were treatd. The treatments were NSE 5% @ 50g/l, Neem oil 2% @ 20ml/l, HaNPV 500 LE/ha @ 1ml/l, Spinosad 45 SC @ 0.6 ml/l, Acetamiprid 20SP @ 0.4 g/l, Rynaxypyr 18.5SC @0.25ml/l, Emamectin benzoate 5 SG @ 0.2 g/l Among above insecticides under study, rynaxypyr 18.5 SP @ 0.25ml/l was most effective insecticide in minimizing the larval population of pigeonpea pod borers viz., gram pod borer, plume moth. The treatment application of rynaxypyr 18.5 SP @ 0.25 ml/l shown the lowest pod damage (14.42 per cent) due to pigeonpea pod borer complex and recorded highest grain yield of pigeonpea (14.72 q per ha) over control.
