Management of pigeon pea pod borers using a novel meta diamide molecule: broflanilide 30% SC

Abstract

Field trials were conducted during kharif 2015, 2016 and 2017 at Agricultural Research Station, Kalaburagi, University of Agricultural Sciences, Raichur, Karnataka, India to study the bio- efficacy of a new green insecticide meta-diamide molecule, broflanilide 30% SC against major pod borer pests of pigeon pea. Among the treatments, broflanilide 30% SC at both the dosage @18.6 and @12.6 g.a.i./ha were highly effective in controlling pigeon pea pod borers by registering lowest mean larval numbers of Helicoverpa armigera (0.19 and 0.42 larvae /5plants, respectively) and Maruca vitrata (0.97 and 1.09 webs/5 plants respectively) at five days after spray. Further because of lower pest load which led to lesser pod damage (6.6 to 8.1%) in above treatments, culminated in higher mean grain yield on 1058.21 and 1031.60 kg/ha respectively). The observations made on activity of natural enemies in the Broflanilide 30% SC treated plots had no effect on the numbers of predatory such as spiders and coccinellids. Further it does not produce any phytotoxicity symptoms in recommended and double the recommended dose.
