Abstract:
A field experiment was conducted during Rabi season of 2021-2022 at the Central Research Farm of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj to evaluate the efficacy of Chlorantraniliprole and bio-agents against fruit borer, Helicoverpa armigera (Hubner) on tomato (Lycopersicon esculentum Mill.) in trans Yamuna region of Prayagraj (U.P). Three applications of eight treatments including control (water spray) against Helicoverpa armigera were used. Among all the treatments highest per cent larva reduction of fruit borer was recorded in T₂ - Chlorantraniliprole (76.35%) followed by T₅ – Chlorantraniliprole + Nisco sixer plus (69.73%), T₆ - Chlorantraniliprole + Neem oil (66.80%), T₁ - Spinosad (62.17%), T₄ – Nisco sixer plus (53.05%), T₃ - NSKE (45.04%) and T₇- Neem oil (43.36%). When cost benefit ratio was worked out the best and most economical treatment was T₂ – Chlorantraniliprole (1:11.70) followed by T₆ - Chlorantraniliprole + Neem oil (1:10.83), T₅ - Chlorantraniliprole + Nisco sixer plus (1:10.68), T₁ – Spinosad (1:10.66), T₄ – Nisco sixer plus (1:10.05), T₃ – NSKE (1:8.22) and T₇ – Neem oil (1:7.93) as compared to T₀ - Control (1:5.35) respectively.
