Bio-Efficacy of sulfoxaflor against plant hoppers in rice

Efficacy of Insecticides Against Rice White Backed Planthopper

“…The data presented in Table 2 also showed that highest incremental cost benefit ratio (ICBR) (1: 3.55) was obtained from the plots treated with pymetrozine 50 WG @ 187.5 g a.i./ ha followed by sulfoxaflor 24 SC @ 218.7 g a.i./ha (1: 2.99). The present findings are in close conformity with the finding of earlier workers viz., Guruprasad et al (2016), Konchada (2017) and Shankar et al (2018) who reported that application of pymetrozine 50 WG and sulfoxaflor 24 SC recorded highest grain yield. The present experiment summarized that the plots treated with pymetrozine 50 WG at 187.5 g a.i./ha and sulfoxaflor 24 SC at 218.7 g a.i./ha significantly reduced the buildup of white backed plant hoppers population with higher yield and economics in rice crop.…”

“…Naik et al (2016) reported that pymetrozine 50 WG @ 0.6 g/ l and imidacloprid + ethiprole @ 0.25 g/ l are effective. Shankar et al (2018) observed that sulfoxaflor 24SC @ 375 ml/ ha is superior, while Guruprasad et al (2016) revealed that sulfoxaflor 24SC @ 438.0 ml/ ha was the best.…”

“…The yield losses vary from 10%-90% (Elanchezhyan et al, 2020;Sujithra and Chander, 2013;Kulshreshta, 1974). Availability of rice crop throughout the year coupled with susceptible varieties in some pockets along with heavy irrigation, higher doses of nitrogenous fertilizers, indiscriminate use of insecticides, lead to serious damage (Elanchezhyan et al, 2020;Shankar et al, 2018). Farmers normally deploy chemical control against this pest.…”
