OxiPhos®

Broad-Spectrum Bactericide / Fungicide

OxiPhos is a combination of phosphorous acid and activated peroxide that provides a one-two punch against diseases. The activated peroxide helps the phosphorous acid active ingredient to have a broader effect on targeted organisms. OxiPhos can be used throughout the growing season to prevent and control diseases caused by the oomycete group of pathogens.

  • Active Ingredients Hydrogen Peroxide Mono- and di-potassium salts of phosphorous acid

What is OxiPhos's mode of action?

  • Systemic Action

    Potassium salts of phosphorus acid, also called potassium phosphite, metabolize inside the plants into phosphorus acid. Phosphorus acid inhibits oxidative phosphorylation in the metabolism of oomycetes and blocks essential pathogen enzymes limiting pathogen growth directly.

  • Contact Action

    Hydrogen peroxide, upon contact with pathogens, oxidizes components of cell membrane resulting in increased cell permeability and eventual death.

How should OxiPhos be used?

OxiPhos has been shown to be chemically compatible with OxiDate 2.0. Combining these two products provides broad spectrum activity against bacterial and fungal diseases during crop growing season. Determine crop sensitivity by spraying small area of foliage before using on large scale. If mixing with other pesticides, determine compatibility and plant sensitivity by following compatibility and plant sensitivity test instructions on the label.
