Field efficacy of flubendiamide 480sc against brinjal shoot and fruit borer (Leucinodes orbonalis)

The field experiments were conducted at Bidhan Chandra Krishi Viswavidyalaya, Kalyani, West Bengal during 2012 and 2013 to evaluate the field efficacy of flubendiamide 480SC against shoot and fruit borer (Leucinodes orbonalis) of brinjal. Seedlings of variety Muktakeshi were transplanted in plots of 25 m² area with a spacing of 60 x 45 cm. The experiment was designed in randomized block design (RBD) with four replications, and treatments viz., flubendiamide 480SC at 90 g, 72g and 60 g a.i./ha; thiodicarb 75 SP (750 g a.i./ha); quinalphos 20 EC (200 g a.i./ha); and water as untreated control. The insecticides were applied twice at 7 days interval. Results revealed that all the treatments gave significant reduction in infestation. It was evident that flubendiamide 480 SC @ 72 and 90 g a.i./ha was very effective with only 1.64 and 1.03% shoot, and 9.11 and 4.44% fruit infestation, respectively along with significant increase in yield.
