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
OxiPhos is effective against
- Downy Mildew
- Bacteria Blight
- Pythium
- Yellow Tuft
- Phytophthora spp and Pythium spp
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 the 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 the crop growing season. Determine crop sensitivity by spraying a small area of foliage before using it on large scale. If mixing with other pesticides, determine compatibility and plant sensitivity by following compatibility and plant sensitivity test instructions on the label.

The Grower's Case for OxiPhos
OxiPhos is the systemic half of BioSafe's two-product disease program. Where ZeroTol 2.0 works on contact to eliminate surface pathogens, OxiPhos builds the plant's own internal defense through induced systemic resistance (ISR). A single application triggers a 21-day ISR window - the plant's systemic defense response stays elevated for three weeks, reducing susceptibility to new infection during that period.
The bidirectional xylem movement is the key agronomic advantage: foliar applications move the phosphite active ingredient down through the plant into the root zone; drench applications move it up into the canopy. This means a single application method covers the full plant system - you don't need a separate foliar and a separate drench to achieve full-plant coverage. Tank mix with ZeroTol 2.0 for a program that delivers both immediate contact kill and sustained systemic defense in a single pass.
