FIELD EFFICACY OF NEWER INSECTICIDE MOLECULES AGAINST SPODOPTERA LITURA FABRICIUS ON CABBAGE

Abstract

An experiment was conducted in Rabi season during 2013-14 to find out the efficacy of newer molecules against Spodoptera litura Fabricius on cabbage. Based on first and second spray the results clearly indicated that the spinosad 45 SC @ 0.025 % (0.19 larva/ plant) proved as the most effective treatment in controlling this pest under field conditions followed by emamectin benzoate 5 SG @ 0.025 % (0.40 larva/plant) against S. litura. However, emamectin benzoate 5 SG was at par with indoxacarb 14.5 SC (0.60 larva/plant), profenophos 40% + cypermethrin 4% (0.71 larva/plant), rynaxypyr 20 SC (0.73 lrva/plant) and thiodicarb 75 WP (0.80 larva/plant), which were registered as second effective group against S. litura. The highest yield of cabbage was recorded in the treatment of spinosad 45 SC (353.26 q/ha) and it was at par with emamectin benzoate 5 SG (334.58 q/ha) and indoxacarb 14.5 SC (327.30 q/ha).
