D.P. Birhade and G.b. Kabre

Abstract

Different insecticides along with soil application of M. anisopliae were evaluated in field trial at the instructional farm of Agril. Entomology Section, College of Agriculture, Dhule for the management of onion thrips (Thrips tabaci L.) in onion during kharif season of 2015-16. All the insecticidal treatments with soil application of M. anisopliae were observed to be effective in reducing thrips infestation on onion crop. Among the evaluated insecticides with soil application of M. anisopliae, the treatment with fipronil 5%SC + M. anisopliae 1X108 CFU was recorded significantly lowest thrips population and was at par with spinosad 45 SC + soil application of M. anisopliae 1X108 CFU, fipronil 5 % SC and spinosad 45 SC. The next superior treatments in order to control thrips in field were lambda cyhalothrin 5EC + soil application of M. anisopliae 1X108 CFU, thiaocloprid 48 SC + soil application of M. Anisopliae 1X108 CFU, lambda cyhalothrin 5EC, thiaocloprid 48 SC, acephate 75SP + soil application of M. anisopliae 1X108 CFU, acephate 75 SP and M. anisopliae 1X108 CFU were found effective treatments against thrips. The average population of thrips was significantly higher in untreated control.
