The efficacy of different insecticides, botanical and bio-agents against jasmine bud worm, Hendecasis duplifascialis Hampson revealed that flubendiamide 39.35%SC @ 0.3ml/l, profenophos 50%EC @ 1.5ml/l and cypermethrin 5%EC @ 0.4ml/l emerged as most promising treatments in managing bud worm from three trials during July to September, 2018. Thiacloprid21.7% SC @ 1.5 ml/lt and thiodicarb 75 WP@ lg/1 had moderate effect in bringing down bud worm infestation. Among bio-agents, Beauveria bassiana lx 10~8 spores/ml @ 1ml/l proved better than Bacillus thuringenesis 17,600IU/mg@1 ml/l and also chemical insecticide treatments viz., thiacloprid and thiodicarb in controlling bud worm and relatively safe to farmers and workers who were involved in buds harvesting on a daily basis. Azadirachtin 0.5% @3ml/lt did not give satisfactory reduction in bud worm damage.
