Abstract:: The inhibitory efficacy of chitosan，sodium alginate，thymol and their combinations on hyphal growth of major pathogenic fungi in post-harvest ‘Lingwuchangzao’，such as Rhizopus stolonifer，Penicillium crustosum，Alternaria alternate (Fr.) Keiss.and Trichoderma roseum (Pers.) were determined.The results showed that the three preservatives and their combinations had a strong inhibitory effect on the four experimental fungi and had a concentration effect.From the experiment that inhibition ratio of hyphal growth on the four experimental fungi in descending order would be chitosan-thymol，sodium alginate-thymol，thymol，chitosan，sodium alginate.Therefore，the inhibitory efficacy of chitosan，sodium alginate in combination with thymol on hyphal growth separately was significantly higher than that of them alone at the same effective concentration.
