Abstract: A Field experiment was conducted at Crop Research Station, Masodha, Faizabad to evaluate the commercial available botanicals along with chemical insecticides Rynaxypyr and Dinotefuran against yellow stem borer (Scirpophaga incertulas, Walker) and Leaf Folder (Cnaphalocrocis medinalis gn.) of rice in agro climatic condition of eastern Uttar Pradesh during kharif 2015 and 2016. The experimental material was comprised of four commercial botanical formulations (Neem Baan, Neemazal, Nimbecidine and Multineem) and neem oil along with recommended insecticides, dinotefuran (Token) and rynaxypyr (Coragen). Chemical insecticide Rynaxypyr (Coragen) 20 SC @ 150 ml/ha was found best to control the infestation of stem borer and leaf folder in both the year of study. Among botanicals Neemazal 1.0% Azadirachtin @ 1000 ml/ha was found most effective to control the incidence of yellow stem borer and leaf folder followed by Multineem 0.03% Azadirachtin @ 2500 ml/ha. Comparable grain yield than chemical insecticide treatments was also recorded with the treatment of botanicals, Neemazal and Multineem. Since these botanicals are eco-friendly and effective to control the population of rice insect pest they can be an alternative to the synthetic pesticides in eco-friendly approach of Integrated Pest Management.
