The invention discloses a strain of phyllosphere
fungus (Muyocopron lithocarpi) DP16 and application of the strain of Muyocopron lithocarpi) DP16 and application of the strain of Muyocopron lithocarpi. The strain DP16 provided by the invention is preserved in the China Center for Type Culture Collection on June 23, 2025, and the preservation number is CCTCC NO: M 20251445. The DP16 provided by the invention can be used for effectively inhibiting various
plant pathogenic fungi and
bacteria, and particularly shows strong activity on
elaeagnus pungens,
staphylococcus haemolyticus, African neem brown root
pathogenic bacteria and the like. And the
fermentation extract also has obvious
oxidation resistance. The invention further provides an optimal
fermentation culture method of the strain, an extraction method of secondary metabolites and application of the strain in preparation of biological control preparations and antioxidants, and important microbial resources and
technical support are provided for development of novel and safe biopesticides and functional products.
