OxiPhos California is a fungicide/bactericide designed to control plant pathogens on both indoor and outdoor crops. The active ingredient is Mono- and di-potassium salts of phosphoric acid at 27.1%. It is effective against a variety of diseases including root rot in citrus, downy mildew in cole crops, cucurbit crops, hops, and leafy vegetables, as well as fly speck and sooty blotch in pome fruit, late blight and pink rot in potatoes, and botrytis storage rot in sugarbeet. Application methods vary by crop, typically involving either a soil drench for root diseases or a foliar spray for foliar diseases. When used as a foliar spray, it is generally applied as a dilute spray (not exceeding 2.5% w/v or 1:40 concentration in water) to ensure complete coverage of foliage. Users should be aware that the product can cause crop injury if applied at higher rates or under certain environmental conditions, such as high temperatures or after rain. Always follow specific directions for the target crop and disease to ensure efficacy and minimize risk.
