Evaluation of insecticides and biorationals against bud worm, Hendecasis duplifascialison Hampson on jasmine

Abstract

Field experiments were conducted to study the efficacy of newer molecules against jasmine budworm Hendecasis duplifascialison Hampson during kharif, 2017 and 2018. The results revealed that the lowest mean percent infested buds was recorded with flubendiamide 39.35 SC @ 0.075 ml/l followed by chlorantraniliprole 18.5 SC @ 0.2ml/l, emamectin benzoate 5 SG @ 0.2 g/l, lambda-cyhalothrin 5 EC, Bacillus thurengiensis, diclorovas 76 EC and commercial neem. Similarly the maximum flower yield of 7215.33 kg/ ha was obtained with flubendiamide 39.35 SC followed by chlorantraniliprole 18.5 SC (6925.67 kg/ha), emamectin benzoate 5 SG @ (6453.67 kg/ha), lambdacyhalothrin 5 EC (6331.33 kg/ha) whereas, lowest flower yield was recorded in untreated control (2549.33 kg/h
