Companion Liquid Biological Fungicide recently received registration in California for turfgrass and landscape use. Manufactured by Growth Products, Companion® effectively prevents, controls and suppresses a broad range of root and foliar diseases including Anthracnose, Brown Patch, Dollar Spot, Summer Patch, Fusarium Patch, Pythium and Phytophthora.

Companion® was the first-ever EPA approved biofungicide, and it is routinely used on some of the world’s top-flight golf courses, sports fields, and private estates. Companion® contains the powerful but environmentally friendly GB03 strain of Bacillus subtilis, which prevents and controls plant diseases through multiple modes of action. GB03 produces a broad-spectrum antibiotic that disrupts pathogen cell-wall formation, and it stimulates a plant’s natural immune system. A competitive and fast colonizing rhizobacterium, GB03 also crowds out pathogens to prevent their growth and antagonistic effects.

Because Companion® is not a chemical fungicide but rather a biological fungicide, pathogens do not develop disease resistance.  This makes Companion® an ideal component of a disease management program.  Companion® can be used in rotation with chemical fungicides or can be tank-mixed with smaller amounts of chemical fungicides for improved efficacy, and thus can reduce potentially harmful chemical applications and lower a total chemical costs.
