OxiPhos Systemic Bactericide Fungicide has a dual mode of action: Systemic and Contact.
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. Potassium phosphite has also shown to enhance the natural defense system of plants.
Hydrogen Peroxide, upon contact with pathogens, oxidizes components of cell membrane resulting in increased cell permeability and eventual death.
