Abstract:
The field experiment was conducted at Instructional farm of BTC CARS, Bilaspur, (C.G.) during Rabi 2022-23, to know the bioefficacy of different biopesticides and insecticides against Helicoverpa armigera on chickpea. After first and second spray all the treatments were observed more or less similar in action against the pest, however, Novaluron + Indoxacarb 5.25% + 4.5% SC recorded with the lowest larvae 1.43 larvae/plant, highest grain yield 8.25 q/ha and maximum cost benefit ratio 1:1.36, while Spinosad 45% SC (1.84 larvae/plant) was the second best treatment. Among the biopesticides, Metarhizium anisopliae 10% (1×109 CFU/ml) recorded with 7.80 q/ha yield and 1:1.31 cost benefit ratio.
