Abstract: In recent years，the development of biopesticides from natural products has been concerned by scholars. For the unique living environment，marine microorganisms producing many novel bioactive compounds that never been found in the terrestrial microorganisms，which provide bright prospects for developing novel biopesticides. The research progress of deep-sea bacteria against phytopathogenic fungi was briefly summarized from three aspects of species diversity，kinds and structures of antifungal substances and antifungal mechanisms. Developing biological pesticide from marine microorganisms was prospected in this paper. This review might provide some insight for development and utilization of marine microorganisms in anti-phytopathogenic fungi.

Key words: deep-sea bacteria, phytopathogenic fungi, mycotoxin-producing fungi, antifungal mechanisms
