• Companion's GB03 strain of Bacillus subtilis is gram-positive (spore-forming) bacteria. This means it can survive periods of exposure to UV light in a desiccated state before becoming active again when moisture becomes present. From a turf management perspective, this means when sprayed on the leaf in the morning, it can survive on the leaf all day (withstands UV) before being washed into the rootzone by rain/irrigation at night where it can survive long term.

    • Companion was the first-ever EPA registered liquid biofungicide in the U.S.
    • Used in 27 countries worldwide
    • Also contains root developing rhizobacteria
