Abstract

Green leaf hopper (Nephotettix nigropictus) is one of the major insect pests of rice in India. The field experiments were carried out during kharif, 2016 and 2017 to assess the bio-efficacy of new molecule of insecticides against green leaf hopper. Among the nine insecticides, application of Spinetoram 6SC +Methoxyfenozide 30 SC @400 ml/ha (3.24 GLH/10 hills) was found to be most effective against rice green hopper damage. But it was statistically at par with spinetoram 6 SC + methoxyfenozide 30 SC @ 375 ml/ha (5.22 GLH/10 hills), flubendiamide 48 SC @ 50 ml/ha (5.50 GLH/10 hills), carbofuran 3 G @ 30 kg/ha followed by need based foliar spray with triazophos 40 EC @ 1500 ml/ha (5.76 GLH/10 hills), acephate 95 SG @ 526 g/ha (5.96 GLH/10 hills), triazophos 40 EC @ 1500 ml/ha (6.17 GLH/10 hills) and triflumezopyrim 106 SC @ 237.5 ml/ha (6.51 GLH/10 hills). Peak duration of occurrence of green leaf hopper was observed almost from 80 DAT and onward period during both years of experimentations. The highest infestation (26.24 GLH/10 hills) was recorded in the unprotected control plots throughout the experimental periods.
