Not AvailableEleven insecticides including a new insecticide sulfoxaflor 24SC and standard insecticide monocrotophos 36SL were evaluated in the field against yellow stem borer and rice gundhi bug during wet season of 2011 and 2012. Plots treated with imidacloprid 17.8 SL @ 500 g a.i. ha−1 recorded lowest (3.6%) dead heart (DH), 3.6% white ear head (WEH), 6.5% grain damage due to gundhi bug and highest grain yield i.e., 5.18 t ha −1 in cv Jaya followed by sulfoxaflor 24 SC @ 90 g a.i. ha−1 (4.61 t ha−1), thiamethoxam 25WG@ 25 g a.i. ha−1 (4.58 t ha−1) and triazophos 40EC @ 450 g a.i. ha−1 (4.56 t ha−1) during 2011. Similar trend was also observed in 2012. During both the years, all the insecticides significantly reduced stem borer and gundhi bug damage over control. The standard insecticide monocrotophos 36SL@500 g a.i. ha −1 was found superior to the new insecticide sulfoxaflor 24SC at lower dose i.e. 75 g a.i. ha−1 against yellow stem borer and gundhi bug damage.Not Availabl
