Evaluation of different insecticide use strategies for the management of shoot and fruit borer in Brinjal
SA Pawar, MN Bhalekar and RV Datkhile
Field experiments for control of brinjal shoot and fruit borer (Leucinodes orbonalis Guene) were conducted during kharif season of 2014-15, 2015-16 and 2016-17. Three strategies viz.; sequential, rotational and ready mix strategy were evaluated. In sequential strategy the treatment consists of chlorantraniliprole 18.5 SC 37.00 g a.i./ha; emamectin benzoate 5 SG @ 12.50 g a.i./ha; spinosad 45 SC @ 112.60 g a.i./ha; chlorpyriphos 20 EC @ 200.00 g a.i./ha; cypermethrin 25 EC @ 62.50 g a.i./ha and these treatments were rotated (followed by each other) in rotational strategy; ready mix insecticide (chlorpyriphos 50% + cypermethrin 5% EC) @ 550 g a.i./ha and untreated control were evaluated. From the three years pooled data, it was observed that the rotational strategy was found effective in reducing the pest infestation which recorded least per cent shoot damage (4.98%) with least fruit damage (9.37% and 7.95%, both on number and weight basis respectively) and 355.81 q/ha marketable fruit yield of brinjal with 1:10.55 ICBR and 1:3.02 B:C ratio.
