Abstract:
The study was carried out to know the impact of of new combination formulation against Spodoptera litura on Groundnut (Arachis hypogaea L.) during September to December 2014, at Research farm, oilseeds research station, Latur. Groundnut crop was infested by Spodoptera litura at moderate levels. The experiment was laid out in randomized block design with seven treatment and three replications with view to find out the effective insecticides combination formulation and it’s most effective dose against Spodoptera litura of groundnut variety Phule Pragati (JL-24) was sown in September. The insecticide and combination formulation used for the treatment were Novaluron 5.25% + Indoxacarb 4.5% SC @ 825 ml/ha Novaluron 5.25% + Indoxacarb 4.5% SC @ 875 ml/ha, Novaluron 5.25% + Indoxacarb 4.5% SC @ 925 ml/ha, Novaluron 10% EC @ 750 ml/ha, Indoxacarb 14.5% SC @ 400 ml/ha, Methomyl 40% SP @ 850 g/ha, along with one untreated control. Among the treatments the results clearly indicated that the combination formulation Novaluron 5.25 + Indoxacarb 4.5% SC @ 875 & 925 ml/ha is equally effective in lowering the infestation of Spodoptera litura.
