abstract
Field experiments was conducted in kharif season during 2017 and 2018 to evaluate bio-efficacy of insecticides against spider in soybean. The pooled data of both the years indicated that there were highest population of spider recorded in control plot (0.97 spider/mrl), chlorantraniliprole 0.4 GR (0.92 spider/mrl) and thiamethoxam 30 FS (0.89 spider/mrl). The lowest population found in imidacloprid 48 FS (0.82 spider/mrl) and phorate 10 CG (0.85 spider/mrl) followed by fipronil 0.3GR (0.87 spider/mrl) and clothiniadin 50 WDG (0.88 spider/mrl). The pooled data of two years indicated that the maximum yield of soybean was recorded in chlorantraniliprole 0.4 GR (26.46 q/ha) followed by clothianidin 50 WDG (25.93 q/ha), fipronil 0.3 GR (25.22 q/ha) and thiamethoxam 30 FS (23.42 q/ha) at par with each other. whereas the lowest yield was found in control plot (18.02 q/ha) and phorate 10 CG (22.40 q/ha).
