Efficacy of Certain Chemicals and Botanicals against Shoot and Fruit Borer, Leucinodes orbonalis (Guenee) on Brinjal (Solanum melongena L.)

The field trial was conducted at Central research farm , SHUATS, Prayagraj, U.P during Kharif season 2023 in randomized block design (RBD) with three replications consisting of eight treatment viz, Neem oil 2%, Chlorantraniliprole 18.5% SC , Spinosad 45%SC, Flubendiamide 480 SC, Indoxacarb 14.5% SC, Pangomia + Flubendiamide, Neem oil + Flubendiamide, and untreated Control, The result revealed that all insecticidal treatments were significantly superior to reduce the incidence of shoot and fruit damage of brinjal compared to untreated control. The plot treated with Chlorantraniliprole 18.5% SC recorded the lowest % of shoot and fruit damage 4.03% and 3.20 % in first and second sprays, respectively followed by spinosad 45% SC (4.43% and 4.15% respectively). The yield ranged from 85 to 225.50 q/ha in all treatments. The highest yield was recorded in Chlorantraniliprole 18.5 % SC (225q/ha) followed by spinosad 45% SC (190q/ha), Flubendiamide 480 SC (17.50q/ha), Indoxacarb 14.5 SC (160.35q/ha), Pangomia + Flubendiamide (140.33q/ha), Neem oil + Flubendiamide (132.40q/ha) and Neem oil 2% (120.50q/ha) as compared to control (85.00q/ha). When cost benefit worked out the best and most economical treatment was Chlorantraniliprole 18.5% SC (1:10.3) followed by Spinosad 45% SC (1:8.5), Flubendiamide 480 SC (1:7.5), Indoxacarb14.5 SC (1:7.4), Pangomia + Flubendiamide (1:6.0), Neem oil + Flubendiamide (1:5.5) and Neem oil 2% (1:5.4) as compared to control (1:4.2).
