Abstract: The study was conducted to evaluate the efficacy of different newer insecticides for controlling leaf folder in rice at Research-cum Instructional Farm of Raj Mohini Devi College of Agriculture and Research Station Ambikapur (C.G.) during Kharif season 2020-21. Seven different insecticides i.e Cartap hydro chloride+ Fipronil 4% + 0.5%CG, Cartap hydrochloride 50%SP, Fluvendiamite 9.35%SC, Fipronil 4% GR, Chlorantraniliprole 0.4%GR, Fipronil 5%SC, Chlorantraniliprole 18.5%SC were used compared to control viz., untreated plot . The result showed that Cartap hydro chloride+ Fipronil 4% + 0.5%CG was the most effective insecticidal treatment against the rice leaf folder for reducing leaf damage by 58.58% and for increasing  yield of grain was by 66.50 % over control among all the treatments under study. Next best insecticides were Cartap hydrochloride 50%SP & and Fluvendiamite 9.35%SC in terms of reduction of yield control. Whereas on terms of yield the other insecticide which show significant increase in yield among rest are Fluvendiamite 9.35%SC and Cartap hydrochloride 50%SP, which  recorded 24.48 and 23.98 grain  yield  respectively. The control, recorded 15.38q  ha-1 grain  yield.
