In order to develop natural antistaling agent for Morchella preservation, reduce environmental pollution problems. In this experiment, the fungus pathogenic fungi were isolated and identified, and the antibacterial activity of the pathogen was determined by using 30 plant essential oils. The results showed that the fungal strain YDJ-S was isolated from the naturally occurring Morchella, belonging to the Fusarium proliferatum, which showed obvious pathogenicity. In vitro antibacterial experiments of essential oils show that in 30 kinds of essential oils, five essential oils of Basil, Cinnamon, Litsea cubeba, Clove and Garlic have obvious inhibitory effect on strain YDJ-S, and the inhibition rate is 100% at 1000 μl/L. Basil essential oil has the most obvious inhibitory effect on the minimum inhibitory concentration and minimum bactericidal concentration of strain YDJ-S, the minimum inhibitory concentration is 250 μl/L, and the minimum bactericidal concentration is 1000 μl/L, to lay the theoretical foundation for further research.
