Year: 2022
Type: article
Abstract: The field trial was conducted at Central Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttarpradesh during Rabi, 2021-2022. The experiment was laid out in RBD (Randomized Block Design). Seven treatments were replicated thrice: Neem oil, NSKE (Neem Seed Kernal Extract) 2%, Flubendiamide 480 SG, Novaluron 10% EC, lndoxacarb 14.5% SC, Emamectin benzoate 5%SG, Spinosad 45% SC and untreated Control. The treatments were tested to compare their efficacy against Helicoverpa armigera and their influences on the yield of tomatoes. Out of all treatments lndoxacarb 14.5% SC, Spinosad 45% SC, Flubendiamide 480SG and Novaluron10% EC recorded the minimum fruit infestation by 10.24, 11.31, 12.21 and 13.21 percent respectively. The highest yield was noticed in lndoxacarb14.5% SC (212.5 q/ha), followed by Spinosad 45% SC (200 q/ha) and Flubendiamide 480 SC (187.5 q/h). The best and most economical treatment is lndoxacarb (1:8.75), followed by Spinosad (1:8.16), Flubendiamide (1:7.55), Novaluron (1:6.38), Emamectin benzoate (1:5.86), Neem oil (1:5.64), NSKE (1:4.63), as compared to control T0-control (1:4.25) having the lowest B: C ratio.
