Evaluation of the efficacy of different eco-friendly insecticides against Whitefly on tomato under polyhouse conditions

Abstract

The present studies entitled “Eco-friendly management of whitefly on tomato under polyhouse conditions” were carried during the years 2019 and 2020 at farmers’ field, Village Surajgarh, Block Matanhail, Distt. Jhajjar (Haryana). Under polyhouse conditions, out of 6 eco-friendly insecticides, Spinosad 45% SC @ 188 ml/ha proved to be most effective treatment in keeping the population of whitefly at significantly lowest level. Neem oil @ 0.3% was found to be the next most effective treatment against whitefly. The cow urine based formulations viz. Brahmastra, Neemastra and Dashparniark were found least effective among all the treatments but significantly better than untreated control.
