Studies on Management of Fruit and Shoot Borer [Leucinodes orbonalis (Guenee)] Using Chemicals and Neem Oil in Brinjal Solanum melongena L.

Abstract

The experiment was conducted at the research plot of the Department of Agricultural Entomology and Central Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, during Rabi from November to February 2021-22 in Randomized Block Design (RBD) with three replications. Eight treatments were evaluated against , Leucinodes orbonalis i.e., Chlorantraniliprole 18.5% EC, Spinosad 45% SC, Flubendiamide 20 WG, Indoxicarb 14.5% SC, Emamectin benzoate 5 SG, Lambda cyhalothrin 4.9% CS, Neem oil 0.15% EC and control in RBD with three replication. The best and most economical treatment was Chlorantraniliprole (1:10.06) which was par with Spinosad (1:8.51) followed by Flubendiamide (1:8.44), Indoxacarb (1:8.04), followed by Emamectin benzoate (1:7.12) and Lambda cyhalothrin (1:6.85), Neem oil (1:6.36) as compared to control (1:4.63).The data on the percent infestation of shoot and fruit borer on brinjal 3rd, 7th and 14th day after first spray reveal that all the chemical treatments were significantly superior over control. Ratio was Chlorantraniliprole 18.5% EC (10.85%, 7.29%), Spinosad 45% SC (11.95%, 9.12%), Flubendiamide 20 WG (13.76%, 9.79%), Indoxacarb 14.5% SC (14.05%, 10.47%), Emamectin benzoate 5 SG (15.59%, 13.46%), Lambda cyhalothrin 4.9% CS (17.09%, 13.46%), Neem oil 0.15% EC (19.97%, 17.43%). The yields among the treatment were significant.The highest yield was recorded in Chlorantraniliprole 18.5% EC (222.50 q/ha), followed by Spinosad 45% SC (198.33 q/ha).
