Bioefficacy and compatibility of Metarhizium anisopliae and new generation insecticide against Helicoverpa armigera infesting chickpea

KD Tekam, NM Kelwatkar and SB Das

The field experiments were carried out during the year 2013-2014 at the experimental field of JNKVV, Jabalpur to evaluate the efficacy and compatibility of Metarhizium anisopliae and new generation insecticide alone and in combination against Helicoverpa armigera infesting chickpea. On the basis of the effectiveness of different treatments against pod borer and the grain yield obtained, it can be said that emamectin benzoate 5 SG, flubendiamide 20 SG and rynaxypyr 20 SC proved to be the most effective treatments, not only in reducing the damage due to pod borer complex but also recorded higher grain yields.
Taking in account the cost of plant protection inputs, the cost benefit ratio value of sole chemicals and combination treatments were close to each other. i.e. 1:8.58 and 1:8.04 for emamectin benzoate and M. anisopliae + rynaxypyr, respectively. By decreasing the dose of chemicals and incorporating biopesticides as combination treatments in pest management programme can give the farmer the advantage of environmental friendly farming and higher economic returns.
