abstract
Field experiment carried out during kharif 2015-16 and 2016-17 at Horticulture Garden, College of Agriculture, Rajendranagar, Hyderabad to evaluate the efficacy of different insecticides on Scirtothrips dorsalis population. The first spray was given after 50% flower initiation and treatments was imposed thrice at 10 days intervals as foliar sprays against the thrips. A total of three sprays were given during the experiment. Data on mean population of 1,3,5,7 and 10days after spraying and per cent reduction over control were calculated after each spray. Cumulative mean of three sprays during kharif in 2015-16 and 2016-17 was worked out. Among that, spinosad at 125 g a.i. ha^-1 was found to be the most effective treatment with 59.09 per cent reduction of Scirtothrips dorsalis followed by fipronil at 500 g a.i. ha^-1 (52.11%), betacyfluthrin + imidacloprid at 30 g a.i. ha^-1 (49.07%), profenophos at 400 g a.i. ha^-1 (47.86%), dimethoate at 300 g a.i. ha^-1 (39.03%), lambda cyhalothrin15.63 g a.i. ha^-1 (35.91%) and chlorantraniliprole at 30 g a.i. ha^-1 (8.58%) over control.
