Managment of defolistors on groundnut through newer insecticides

Abstract

A field experiment on bio-efficacy of newer chemical insecticides against defoliator pests was carried out at Oilseeds Research Station, Latur, Maharashtra during kharif, 2012 in randomized block design (R.B.D.) with eight treat ments Viz., Rynaxypr 20 SC (100 ml/ha), Flubendiamide 480 SC (150 ml/ha), Spinosad 45 SC (175 ml/ha), Thiodicarb 80 DF (1000 ml/ha), Novaluran 10EC (1000 ml/ha), Dichlorvos 76 WSC (625ml/ha), Chlorpyrifos 20 EC (1500 ml/10 lit) and untreated Control. The experimental results indicated that Spinosad 45 SC @175 ml/ha was found significantly superior for control of defoliators was followed by the treatment of Rynaxypr 20 SC @100 ml/ha and Novaluran 10EC @1000 ml/ha. The highest pod yield was recorded by Spinosad 45 SC @175 ml/ha i.e. 3931kg/ha and was followed by Rynaxypr 20 SC@100 ml/ha (3382 kg/ha).
