  • Genetically modified Pseudomonas strains with enhanced biocontrol activity
    Patent number: 5756087
    Abstract: Strains of Pseudomonas have been genetically engineered to have enhanced biocontrol properties. The strains of the invention are particularly effective against plant pathogenic fungi such as species of Rhizoctonia and Pythium, because the strains produce enhanced amounts of antifungal metabolites such as pyrrolnitrin that are active against these fungal pathogens. Both the genetically modified biocontrol strains and the antifungal metabolites can be used as active agents for biocontrol compositions.
