 ABSTRACT

A field experiment was carried out in the experimental research farm, NU: SASRD, Medziphema, Nagaland, during the time period July to October 2016, to assess the efficacy of some novel insecticides against Spodoptera litura on soybean. Seven chemicals viz. Imidacloprid 40 FS @ 1.25ml/kg seed, Thiamethoxam 30 FS @ 10ml/kg seed, Chlorantraniliprol 18.5 SC @ 100ml/ha, Indoxcarb 15.8 EC @ 333ml/ha, Quinalphos 25EC @ 1500ml/ha, Thiacloprid 21.7 SC @ 650ml/ha and Triazophos 40EC @ 800ml/ha were used for the field experiment. The highest mean per cent reduction after first spray in the population of tobacco caterpillar, Spdoptera litura Fabricius of 84.89 per cent was observed in the plot treated with Chlorantraniliprole 18.5 SC followed by 81.28 per cent reduction in population in the plot treated with Quinalphos 25EC having no significant difference between them. The lowest per cent reduction of 23.59 per cent was recorded in Thiamethoxam 30 FS.  After second spray, the highest mean per cent reduction in the population of tobacco caterpillar, Spdoptera litura Fabricius was observed in the plot treated with Quinalphos 25EC with a mean per cent population reduction of 98.87 per cent followed by 87.36 per cent reduction in population in the plot treated with Thiacloprid 21.7 SC. The lowest per cent reduction of 20.15 per cent was recorded in Thiamethoxam 30 FS.
