Evaluation of insecticides in the management of fruit flies infesting ridge gourd

Abstract

The field experiment was carried out on evaluation of insecticides in the management of fruit flies infesting ridge gourd during kharif season of 2017 at Central Experimental Station, Wakawali, Dist- Ratnagiri. During this study evaluate six insecticides viz., spinosad 45 SC @ 0.014, emamectin benzoate 5 SG @ 0.002, deltamethrin 2.8 EC @ 0.0024, azadirachtin (1%) @ 0.003, dichlorvos 76 EC @ 0.05 and malathion 50 EC @ 0.05 percent respectively. The results regarding overall mean of three sprays on the efficacy of insecticides indicated that spinosad 45 SC @ 0.014 percent was the best treatment which recorded minimum (23.55%) mean fruit infestation and was at par with emamectin benzoate 5 SG @ 0.002 percent (24.77%) and deltamethrin 2.8 EC @ 0.0024 percent (25.93%). All the above treatments were found to be superior over untreated control which recorded highest (47.19%) fruit infestation.
