  • Protection of plants against frost injury using ice nucleation-inhibiting species-specific bacteriophages
    Patent number: 4375734
    Abstract: Frost-sensitive plants are protected against frost injury by topical application thereto of non-phytotoxic virulent bacteriophages which are species-specific to the ice-nucleating bacteria normally present on the plants. The bacteriophages selectively attack the ice-nucleating bacteria and inhibit their ice-nucleating activity, thereby reducing the temperature at which frost injury occurs.
