A field experiment on the efficacy of certain biopesticides for control of chilli thrips, Scirtothrips dorsalis Hood conducted at the Central field, Sam Higginbottom University of Agriculture Technology and Sciences, Allahabad, Uttar Pradesh, India during July 2016 to November 2016. Results revealed that among the different treatments, Spinosad (73.21%) proved to be the most effective treatments followed by Imidacloprid (67.58%), Pongima oil (55.78%), Neem oil (55.64%), NSKE (53.03%) and Garlic sap extract (50.03%), whereas, Beauveria bassiana (33.36%) was found to be least effective against this pest. The plots treated with Spinosad show highest (272.33q/ha) yield was followed by Imidacloprid (250.88q/ha), Pongamia oil (192.62q/ha), Neem oil (185.70q/ha), NSKE (165.66q/ha) and Garlic sap extract (142.32q/ha), and Beauveria bassiana (133.80q/ha). Economics of different treatments showed appreciable Incremental Cost-Benefit Ratio obtained in case of Spinosad (1:11.36) followed by Imidacloprid (1:10.88), Pongima oil (1:8.19), Neem oil(1:7.92), NSKE (1:6.52) Garlic sap extract(1:5.69), Beauveria bassiana (1:5.30) as compared to control (1:3.74) respectively.
