Field Evaluation Of Novel Insecticides Against Brown Planthopper (Nilaparvata Lugens) And White Backed Planthopper (Sogatella Furcifera) In Rice

A field experiment was conducted to evaluate the bioefficacy of novel insecticides against brown planthopper [Nilaparvatha lugens (Stal)] (BPH) and white backed planthopper [Sogatella futrifera (Hoverth)] (WBPH) on rice. The results revealed that field application of triflumezopyrim 10 SC @ 235 ml per ha was found superior and registered 1.88 and 1.26 hoppers per hill against BPH and WBPH followed bypymetrozine 50 WG @ 300g per ha with 2.12 and 1.26 hoppers of BPII and WBPI I per hill, respectively. The response of these insecticides was also observed on the yield attributes, with highest grain yield of 55.58 q/ha in trifltunezopyrim 10 SC (ib 235 ml per ha followed by pymetrozine 50 WG @ 300 g per ha (53.79 q/ ha).
