Abstract
The present research was conducted at the Central Research Field of Department of Agricultural Entomology, Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj during the Rabi season of 2021-22. The treatments used during the study were Metarhizium anisopliae, Beauveria bassiana, Karanj Oil, Neem Oil, Spinosad, Emamectin benzoate + Indoxacarb and Indoxacarb. The results revealed that highest percent reduction in larval population was observed in Emamectin benzoate 5% SG + Indoxacarb 14.5% SC (73.57%) and was most successful in bringing down the larval population. It is then followed by Spinosad 45% SC (65.03%), Indoxacarb 14.5% SC (59.02%), Beauveria bassiana (1x108 cfu) (54.87%), Metarhizium anisopliae (1x108 cfu) (50.92%), Neem Oil 2% (45.81%). While, Karanj Oil 2% prove to be the least effective treatment in reducing the larval population (37.53%).
