abstract
The experiment was conducted during the 2011 and 2012 in the University farm at Kalyani, West Bengal state of India. Brinjal ‘Muktakeshi’ was grown in plots measuring 5 m×5 m, at spacing of 1m x 0.75m with three replications during the period from mid- April to July, two year, following recommended package of practices. The plots were set out in a randomized block design with eight treatments including an untreated check. Four doses of cyazypyr 10% OD (60, 75, 90 and 105g a.i./ha in both year 2011 and 2012) were sprayed every year for their efficacy along with fipronil 5% SC @ 60 g a.i./ha, Flubendiamide 40% SC @ 30g a.i./ ha and Profenofos 50% SC @ 500 g a.i./ ha as standard check against E. vigintioctopunctata. This experiment revealed that all these treatments were significantly superior over untreated control. The most effective treatment was cyazypyr 10% OD @ 105g a.i./ha followed by cyazypyr 10% OD @ 90g a.i./ha.
