Abstract
Present study was carried out at the Farm of Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during 2022-23. In order to study the bio-efficacy of insecticides; field experiment was laid with six treatments viz., chlorantraniliprole 0.53%G @ 29.81 g a.i/ha,chlorantraniliprole 0.53%G@39.75g a.i/ha, chlorantraniliprole 0.53%G@49.69 g a.i/ha, chlorantraniliprole 0.4G@ 40 g a.i/ha and fipronil 0.3G @75 g a.i/ha including the untreated control. In case of stem borer and leaf folder chlorantraniliprole 0.53%GR @39.75g a.i/haprovided significantly better control followed by chlorantraniliprole 0.53% GR @ 49.69g a.i/ha, Fipronil 0.30% GR@ 75g a.i/hachlorantraniliprole 0.53%G @ 29.81 g a.i/ha and Chlorantraniliprole 0.40% GR@ 49.69g a.i/ha. It was concluded that the Bio-efficacy of insecticidal treatments against major pests of paddy showed that chlorantraniliprole 0.53%G 39.5g a.i/ha was first best insecticidal treatment against both Lepidopteran insect pests of paddy.
