Evaluate the efficacy of Bio-Pesticides and novel insecticides against to mato fruit borer helicoverpa armigera (HUB.) in Western Plain Zone of U.P. with the cost benefit ratio

Fruit borer, Helicoverpa armigera (Hübner) is the most destructive insect pest that devastates the crop of tomato, a widely consumed vegetable in India. In an effort to control its spread, we tested a spectrum of pesticides and showed that under field conditions. Emamectin benzoate are most efficient in reducing larval population percent fruit infestation with highest number of healthy fruits in these treatments. Based on weight of fruits of tomato per plant, spinosad and emamectin benzoate are found to be most effective. Treatments with spinosad and emamectin benzoate provide highest marketable fruit yields with highest C: B ratio recorded in plots treated with spinosad and emamectin benzoate.
