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.
OxiPhos has a dual mode of action: systemic and contact. It can be used on crops, turf, and ornamentals, and is effective against downy mildew, bacterial blight, phytophthora, pythium, and more.
Rate of use: for foliar spray, use 42.3 fl. oz. per 100 gallons of water, applied at a rate of 30-100 gallons of spray solution per treated acre. Apply at first sign of disease and repeat as needed at 7-14 day intervals. Can also be used for soil drench or transplant dip; see label for application rates.
