Abstract:
The present investigation entitled, “Field efficacy and economics of some biopesticides against tomato fruit borer [Helicoverpa armigera (Hubner)]. Cultivar i.e. Pusa Ruby was conducted during November to March 2021-2022 at Central Research Farm of Sam Higginbottom University of Agriculture, Technology and Sciences, Naini, Prayagraj. Two application of eight treatments against Helicoverpa armigera were used. Among all the treatments highest per cent reduction of fruit borer was recorded in T1 – Chlorantraniliprole (68.34%) followed by T4- Spinosad (64.22%), T3 - Nisco Sixer plus (62.04%), T7 – HaNPV (57.93%), T6 – Bacillus thuringiensis (52.93%), T5 – Beauveria bassiana (49.69%), T2- Nimbecidine (46.58%). When cost benefit ratio was worked out the best and most economical treatment was T1 – Chlorantraniliprole (1:9.14) followed by T4 – Spinosad (1:8.84), T3 - Nisco Sixer plus (1:8.04), T7 – HaNPV (1:7.53), T6 – Bacillus thuringiensis (1:6.51), T5 – Beauveria bassiana (1:6.34), T2- Nimbecidine (1:5.67) as compared to T0- Control (1:4.58).
