Abstract :

Cinnamyl acetate obtained from the culture filtrate of strain of Verticillium dahliae, grown in liquid Czapeck medium, was synthesized and tested for its phytotoxicity on seedlings and plantlets of tomato and alfalfa and on potato leaves. The results showed that cinnamyl acetate (VdT) is a phytotoxic substance that induces wilting, dehydration, chlorosis and necrosis on alfalfa, tomato and potato via laboratory bioassays. Similar to those symptoms observed on the same hosts naturally infected with V. dahliae. This is the first report of the phytotoxicity of this compound on alfalfa, tomato and potato.
