Abstract

A field experiment was conducted in School of Agricultural Science and Rural Development (SASRD), Medziphema (Nagaland) to evaluate the efficacy of new insecticide molecules against Mylabris phalerata in soybean crop. The treatments consisted of Imidacloprid 48 FS @ 1.25ml/kg seed, Thiamethoxam 30 FS @ 10ml/kg seed, Chlorantraniliprole 18.5 SC @
100ml/ha, Indoxacarb 15.8 EC @ 333ml/ha, Quinalphos 25 EC @ 1500ml/ha, Thiacloprid 21.7 SC @ 650ml/ha, Triazophos 40 EC @ 800ml/ha and a control plot. The occurrence of the insect pest was absent during first spray at initial development of the crop. However during flowering stage, the second spray was initiated after the occurrence of the adults. The plot
treated with Quinalphos 25 EC @ 1500ml/ha recorded the highest mean reduction percentage of 67.27 % of adult population, this was followed by Thiacloprid 21.7 SC @ 650ml/ha with a mean per cent reduction of 65.99 which was significantly at par with plot treated with Imidacloprid 48 FS @ 1.25ml/kg seed with mean reduction per cent of 64.
