Abstract:
Sorghum (Sorghum bicolor) is highly valued crop cultivated worldwide food and fodder. Investigations were carried out to study the “Efficacy of different insecticides against Rhophalosiphum maidis on Rabi Jowar” Studies revealed that Imidacloprid 17.8 SL (1.46 aphid/3leaf) proved effective and this treatment was found statistically equal with thimethoxam 12.6% + lambda cyhalothrin 9.5 ZC (3.13 aphid /3leaf). Whereas, the treatments emamectin benzoate 5 SG (5.09 aphid /3leaf), indoxacarb 14.5 SC (6.12 aphid /3leaf), chlorantraniliprole 18.5 SC (7.87 aphid /3leaf), flubendiamide 39.35 SC (8.62 aphid /3leaf) and Spinosad 45 SC (11.64 aphid /3leaf) found at par with each other and were the next best treatments for reducing aphid infestation. However, water spray recorded maximum population (26.73 aphid /3leaf). The results indicated that all the insecticide treatments were significantly superior in grain yield of Rabi jowar over water spray.
