abstract
An investigation to study the efficacy of some novel insecticides and bio-products against shoot fly, Atherigona soccata (Rondani) in maize was carried out for two consecutive seasons i.e. 2013 and 2014, at Crop Research Centre, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut. Efficacy of different insecticides and bio-products viz. Imidacloprid 70WS, Thiamethoxam 70WS, Carbofuran 3G, Phorate 10G, NSKE, Cow urine-NSKE, Imidacloprid 70WS-NSKE and Thiamethoxam 70WS-NSKE were evaluated against number of eggs of A. soccata revealed that the treatments, Imidacloprid 70WS-NSKE was found best to reduce the number of eggs laid by A. soccata i.e. 0.00 eggs/plant (11 DAE) and 0.45 eggs/plant (22 DAE) followed by Thiamethoxam 70WS-NSKE with 0.45 eggs/plant (11 DAE) and 0.72 eggs/plant (22 DAE). However, the maximum number of eggs survival of A. soccata was recorded with untreated control 1.85 eggs/plant (11 DAE) and 2.30 eggs/plant (22 DAE). Result revealed that all the treatments were found significantly effective in reducing the incidence of shoot fly and thus increasing the yield as compared to control. The higher grain yield (42.93 q/ha) and cost benefit ratio (1:16.10) were also obtained from Imidacloprid 70WS-NSKE.
