Abstract: A research experiment entitled Assessment of impact of Chlorfenapyr 240 SC Against fruit borer of Tomato was carried out in randomized block design (RBD) during Rabi season at experimental site, College of Agriculture, Indore (MP). To assess the impact of insecticides against fruit borer. The population counted on 5 plants at 1, 3, 5, 7 and 10 day after each spray. The maximum reduction in larval number of fruit borer was noted in T5-Chlorfenapyr 240 SC @ 480ml/ha (95.46 %) followed by T4- Chlorfenapyr 240 SC @ 288 g a. i. /ha (94.28 %), T3-Chlorfenapyr 240 SC @ 240 g a. i. ha-1 (92.70 %), T2-Chlorfenapyr 240 SC @ 192 g a. i. /ha (90.76 %), T6-Cynantraniliprole 10.26 % OD 100mlha-1 (89.56 %), T7-Dimethoate 30 % EC @ 150 gmha-1 (87.66 %). The minimum percent reduction of fruit borer was found in T1-Chlorfenapyr 240 SC @ 144 g a. i. ha-1 (85.34 %) compared to untreated control. The higher fruit yield also recorded in T5-Chlorfenapyr 240 SC @ 480ml/ha (32 t/ha) followed by T4- Chlorfenapyr 240 SC @ 288 g a. i. /ha (27 t/ha).
