Singh Devendra, Gupta PK, Chandra Umesh, Vikrant and Kumar Akshay

An experiment was conducting during kharif, 2013 at Main Experimental Station of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad-224 229 (U.P.) to evaluate the efficacy of some insecticides at different doses against the yellow stem borer scirpophaga incertulas (Walker) in rice ecosystem. The application of insecticides was done after transplanting, when the pest population reached at their ETL (Economic threshold level). The result shows that among all the insecticides (treatments), profenofos 40 + cypermethrin 4 (44 EC) 880 gm a.i. was most effective against the yellow stem borer, scirpophaga incertulas (Walker) (1.25 per cent) followed by profenofos 40 + cypermethrin 4 (44 EC) 440 gm a.i. (1.75 per cent) and conversely protected the crop. The least efficacy of treatment was found in lambda cyhalothrin 5 EC (3.75 per cent) treated plots. All the treatments were found effective and significantly superior over the control.
