Abstract:
An investigation was conducted to know the effectiveness of newer insecticides on Coccinellid beetles in green gram. The experiment was conducted at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut, during Kharif season 2019 using Randomized Block Design with eight treatments (Emamectin benzoate, Spinosad, Chlorantroniliprole, Indoxacarb, Novaluron, Profenophos, Triazophos, and control treatment) and three replications on variety SML668. Recordings were taken at three, seven, and eleven days after the first and second pesticide application, and the data was analyzed. Among all the treatments, Novaluron 10EC @ 1 ml/ lit water was found safest with the maximum number of C. septempunctata followed by Profenophos 50 EC@ 1 ml/ lit, Triazophos 40 EC@ 4.0 gm per liter of water, Indoxacarb 14.5SC @ 1.0 gm per liter of water, Chlorantraniliprole 20SC @ 0.25 gm per liter of water and Spinosad 45 SC @ 0.25 ml per liter of water and Emamectin benzoate 5 SG @ 0.4 gm per liter of water. The most harmful treatment against C. septempunctata was recorded Emamectin benzoate 5 SG@ 0.4 gm per liter of water.
