英文摘要	Yellow stem borer, Scirpophaga incertulas Walker and leaf folder, Cnaphalocrocis medinalis Guenee are two dominant species among the rice insect pests and cause considerable economic losses in India. Various strategies have been applied for managing these pests and insecticides as chemical control factors are the first line of defense but it has become difficult to manage these pests due to the development of resistance. Therefore, identification of new molecules with selective properties, novel mode of action, low toxicity to non-targets and environmental safety is required with a view of sustainable pest management. In this direction, a new molecule i.e., flubendiamide 20 WG was evaluated under field conditions to access its bio-efficacy against yellow stem borer and leaf folder during rainy seasons of 2019 and 2020. The results of present investigations indicate that spray of flubendiamide 20 WG @ 25 g a.i. ha(-1) first at tillering stage (30 days after transplanting) and second at panicle initiation stage (50 days after transplanting) or whenever the pests cross economic threshold level was found effective and best insecticidal treatment in mitigating the damage caused by yellow stem borer and leaf folder and consequently translated in higher grain yield during both the experimental seasons. Bio-efficacy of other insecticides viz. chlorpyriphos 20 EC @ 500 ml g a.i. ha(-1), cartap hydrochloride 4G @ 750 g a.i. ha(-1) and quinalphos 20 AF @ 200 ml a.i. ha(-1) against yellow stem borer and leaf folder was significantly inferior to flubendiamide 20 WG @ 25 and 30 g a.i. ha(-1) but superior over the control. No phytotoxicity symptoms were inflicted by foliar application of flubendiamide 20 WG (20, 25 and 30 g a.i. ha(-1)) on the rice crop during both the years of study. Phytotoxicity was recorded zero on scale of 0-10 indicating its 100% safety to the crop. Flubendiamide 20 WG was also found safe to different natural enemies viz. green mirid bug Cyrtorhinus lividipennis Reuter; seven spotted lady beetle, Coccinella septempunctata (Linnaeus) and spiders (Araneae: Aranidae) recorded in the rice field. Population of green mirid bug Cyrtorhinus lividipennis Reuter; seven spotted lady beetle, Coccinella septempunctata (Linnaeus) and spiders (Araneae: Aranidae) was recorded 1.74, 1.65 & 1.96/10 hills in the application of flubendiamide 20 WG @ 25 gm a.i. ha(-1) as compared to 1.86, 1.70 & 2.12 in control, respectively during rainy season, 2020 indicating a non-significant difference among the treatment and control. Maximum grain yield (35.27 & 36.56 q ha(-1)) was observed in the treatments having the application of flubendiamide 20 WG @ 30 gm a.i. ha(-1) during 2019 & 2020 crop seasons, respectively and it was at par with 25 g a.i. ha(-1). The residues of flubendiamide 20 WG at 25 and 50 g a.i. ha(-1) analyzed at harvest were below 0.01 mg kg(-1) (limit of quantification) in paddy straw, grain and field soil.
