[Objective] The purpose aimed to study the antibacterial activity of Carya cathayensis pericarp extract. [Method] The antibacterial activity of C.cathayensis pericarp extract was measured by analyzing the inhibitory effect of C.cathayensis pericarp extract on the mycelium growth and conidial spore germination of Fusarium oxysporum f.sp. cucumerinum and Botrytis cinerea Pers.. [Result] C. cathayensis pericarp extract could evidently inhibit the mycelium growth of test strains and the germination and tube growth of conidia. Compared with control, the inhibition rate on the spore generation of Fusarium oxysporum f.sp. cucumerinum was 73.9% and the inhibition rate of the tube growth was 63.5% after culture 9 days. For Botrytis cinerea Pers., the inhibition rate on the spore generation and the tube growth was 82.7% and 65.1% respectively. Furthermore, C.cathayensis pericarp extract had obvious promotion effects on the seed germination of cucumber. [Conclusion] The research provided the theoretical basis for developing C. cathayensis pericarp extract as antiseptic.
