Abstract:
The research work entitled “Evaluation of different insecticides against gram pod borer, Helicoverpa armigera (Hubner)” was undertaken at CRF, Prayagraj, Allahabad, Uttar Pradesh, with eight treatments including control viz. (T1) HMO-Horticulture Mineral oil, (T2) Beauveria bassiana, (T3) Metarhizium anisopliae, (T4) Bacillus thuringiensis Var. Krustaki, (T5) Neem oil, (T6) Emamectin benzoate 5% SG, (T7) Novaluron and (T0) Untreated control in RBD with three replications targeting for the evaluation of different insecticides against gram pod borer, H. armigera. Data was taken on chickpea pod borer population. The larval population of chickpea pod borer H. armigera on third, seventh and fourteen days after spraying revealed that the Effective treatment for pod borer is T6-Emamectin benzoate followed by T7-Novaluron, T4-Bacillus thuringiensis Var. Krustaki, T2-Beauveria bassiana and T3-Metarhizium anisopliae and among the botanicals and petroleum byproducts, the best treatment with minimum percentage of pod borer was recorded in T5-Neem oil followed by T1-HMO. The B:C ratio of various insecticides treatments were calculated and interesting results were achieved. The maximum B:C ratio (1:4.8) was recorded for T6-Emamectin benzoate followed by T7-Novaluron (1:4.5), T4-Bacillus thuringiensis Var. Krustaki (1:4.1), T2-Beauveria bassiana (1:3.9), T3-Metarhizium anisopliae (1:3.8), T5- Neem oil (1:3.6), T1-HMO (1:3.3) and the minimum B:C ratio was noted in T0-Control plot (1:2.3).
