Abstract: The effects of different concentrations of chitosan on the antifungal activity against six different plant Fusarium oxysporum were investigated.The results indicated that the chitosan have antifungal activities within certain concentration range,and the distortion of morphology of plant Fusarium oxysporum treated with chitosan is found.With the increasing of chitosan concentration,the inhibitory activity of it increased,and at 0.4%,the antifungal activity was strongest,while the antifungal activities decreased with the chitosan concentration increased continuously,which might be due to the reduction of the chitosan effective concentration through aggregation by hydrogen bond.
