Abstract
Laboratory and field experiments were conducted at Annamalai University, Department of Entomology, Chidambaram during 2018-2020 to evaluate the bio-efficacy of ethiprole 10.7 % + pymetrozine 40 % WG against brown planthopper in rice. The results revealed that ethiprole 10.7 % + pymetrozine 40 % WG @ were effective in the management of brown planthopper. Ethiprole 10.7 % + pymetrozine 40 % WG was found to be safer on natural enemies viz., spiders and mirid bugs. The highest yield were obtained from ethiprole 10.7 % + pymetrozine 40 % WG @ treated plots in both seasons.
