Management of Sucking Complex in Bt Cotton Through the Application of Different Plant Products

Abstract

The effect of different plant extracts (neem oil, g arlic, eucalyptus and datura) on the population of jassid, Amrasca devastans (Dist.), whitefly, Bemisia tabaci (Genn.) and thrips, Thrips tabaci (Lind.) were tested in Bt cotton under field condit ions. All the plant products showed varying toxicity against sucking co mplex of Bt cotton 24, 72, 168 and 240 hours after application. Datura proved to be th e most effective bringing about significant reduction in the pest population follow ed by neem oil. Garlic and eucalyptus also produced significant results compared to untre ated check. However, the two times application of plant products revealed garlic and e ucalyptus significantly less effective than Datura and neem.
