Online published on 23 October, 2018. Abstract Field experiments were conducted during pre-kharif season of 2011 and 2012 at University Experimental Farm, Unit C, Kalyani, West Bengal to study the efficacy of a ready mix formulation of spirotetramat 120 + imidacloprid 120: 240 SC at three combination doses (i.e., 45+45 g a.i./ha, 60+60 g a.i./ha and 75+75 g a.i./ha) against the jassid, whitefly and red spider mite. Six standard checks viz., spirotetramat 150 OD @ 75 g a.i./ha, imidacloprid 200SL @ 75 g a.i./ha, dicofol 18.5% EC @185 g a.i./ha, oxydemeton methyl 25 EC @ 250 g a.i./ha, dimethoate 30 EC @300 g a.i./ha and thiamethoxam 25 WG @ 25 g a.i./ha along with a untreated check were also evaluated. The study revealed that the combination of spirotetramat 120 + imidacloprid 120: 240 SC @ 75+75 g a.i./ha was the best treatment in terms of minimum pest population as well as maximum yield. Top Keywords Brinjal, jassid, whitefly, red spider mite, spirotetramat 120+ imidacloprid 120240 SC formulation, infestation, yield. Top |
