MANAGEMENT OF THRIPS IN MUNGBEAN CROP USING NEEM OIL (AZADIRACHTA INDICA A. JUSS) AND DIFFERENT INSECTICIDES

Abstract

A field study to test the comparative efficacy of synthetic insecticides (Confidar 200 SL @ 250 ml acre^-1, Mospilan 20 SP @ 250 ml acre^-1, Actara 25 WG @ 48 gm acre^-1) and neem oil concentrations (Neem oil 1%, Neem oil 2% and Neem oil 3%) against thrips in mungbean crop was conducted at Arid Zone Research Institute (AZRI), Bhakkar (Punjab) during the kharif season 2011. The Experiment was laid out in randomized complete block design (RCBD) with three replicates. Mospilan 20 SP treated plot comparatively showed least per infloresence population of thrips (5.08) followed but not significantly different to Actara 25 WG with 5.75 thrips per infloresence. Among neem oil concentrations tested, although, all the concentrations (1, 2 and 3%) showed comparatively low per infloresence population of thrips than control plot but neem oil 3% showed comparatively least per infloresence population of thrips (10.83). In case of percent population reduction of thrips over control, maximum population reduction of thrips (65.06%) was found in plots treated with Mospilan 20 SP followed but not significantly different to Actara 25 WG treated plot with 60.57% population reduction of thrips. Among neem oil concentrations tested, neem oil 3% showed comparatively more population reduction (25.51%) of thrips than other tested concentrations of neem oil.
