Bioefficacy of a Diamide Insecticide, Flubendiamide 480 SC against Shoot and Fruit Borer (Leucinodes orbonalis Guen.) in Brinjal

Field evaluation was conducted to study the efficacy of Flubendiamide 480 SC against brinjal shoot and fruit borer (Leucinodes orbonalis Guen.) during two consecutive seasons of 2014. On the basis of percent shoot and fruit infestations, Flubendiamide 480 SC @ 60-90 g a.i./ha was found most effective treatments (1.28-3.48% shoot and 2.15-3.08% fruit) followed by Quinalphos 20 EC @ 200 g a.i./ha (3.99% shoot and 3.57% fruit). Thiodicarb 75 SP @ 750 g a.i./ha was recorded the least effective treatment (4.29% shoot and 4.07% fruit infestation). The highest marketable fruit yield was obtained with Flubendiamide 480 SC @ 60-90 g a.i. /ha (79.50-87.05 q/ha). The new diamide insecticide, Flubendiamide 480 SC found promising in reducing the infestation of L. orbonalis by maximizing the marketable fruit yield. This novel insecticide may be effectively utilized in the IPM programmes of brinjal.
