Laboratory experiments were conducted to evaluate the effect of sorghum, sunflower, brassicaand mulberry water extracts on mortality of cabbage aphid Brevicoryne brassicae (L.) (Homoptera:Aphididae) which damages the canola crop. The aphids were collected from canola field and applied withdifferent concentrations of allelopathic water extracts or their combinations under laboratory conditions.Allelopathic water extracts of crops such as sorghum, brassica, sorghum + mulberry, sorghum + sunflowerand sunflower alone were effective in controlling the aphid. The higher concentrations of these extracts(8 or 16%) were most effective in controlling aphid (>50%) at 24 h after application.
