Abstract: To investigate the effects of the extracts solution of parsley seed on the pathogenicity of Fusarium oxysporium f.sp. cucumerinum, the change of the activity of the three cell wall-degrading enzymes and content of the toxins (fusarinic acid) of Fusarium oxysporium f.sp. cucumerinum were studied by the methods of liquid culture. The result showed that, the activity of the three cell wall-degrading enzymes (pectinase, cellulase,β-glucosidase) secreted by cucumerinum was lower than the control after the extract treatment. And the contents of the toxins (fusarinic acid) produced by cucumerinum lower by 20.02%, 31.50% and 34.18% than the control. So allelochemicals of the eextracts solution of parsley seed inhibited the activity of cell wall hydrolase, and impeded the contents of fusarinic acid, and weakened the ability of pathogenicity to host.
