The invention discloses a trichoderma citrinoviride strain. The trichoderma citrinoviride strain is preserved in China General Microbiological Culture Collection Center (CGMCC), and the preservation number of the trichoderma citrinoviride strain is CGMCC No. 8722. The trichoderma citrinoviride strain has the advantages that the trichoderma citrinoviride strain dissolves pathogenic fungus cell walls through the self-produced fungal cell wall degrading enzyme, the trichoderma citrinoviride strain seeps into the cells of pathogenic fungi to form a large amount of branches and sexual structures, the growth of the pathogenic fungi is inhibited, and the pathogenic fungi die; the pathogenic fungi of pepper damping-off can be efficiently inhibited by the trichoderma citrinoviride strain, pepper damping-off is reduced, and the trichoderma citrinoviride strain can replace chemical pesticides to inhibit pepper damping-off while environmental protection is achieved.

The invention provides a COD (chemical oxygen demand)-degrading fungicide agent and a preparation method thereof. The COD-degrading fungicide agent comprises compound fungicide liquid, a protective agent and a carrier, wherein the compound fungicide liquid comprises Aspergillus calidoustus liquid, trichoderma citrinoviride liquid, aspergillus niger liquid and rhizopus stolonifer liquid; the protective agent comprises skim milk powder, trehalose, calcium carbonate and glycerin. The preparation method comprises the following steps of (1) mixing the Aspergillus calidoustus liquid, the trichoderma citrinoviride liquid, the aspergillus niger liquid and the rhizopus stolonifer liquid into the compound fungicide liquid, adding the protective agent, and uniformly mixing; (2) crushing the carrier and treating by a 60 to 100-mesh sieve; (3) adding the crushed carrier into the compound fungicide liquid, uniformly mixing, pre-freezing, and drying, so as to obtain the fungicide agent. The fungicide agent has the advantages that the fungicide agent is used as a degradable microorganism, the strain is stable, the synergistic action is obvious, and the COD in sewage is favorably degraded.
