PHOSPHO-jet is a systemic fungicide used for the control of various plant diseases, including anthracnose, canker, dieback, and various root rot issues. Its active ingredient is Phosphite (as salts of Phosphorous Acid) at a concentration of 45.8%. It is designed for use on a wide variety of plants including apples, grapes, citrus, avocados, mangoes, palms, turf, and various ornamental plants. The product can be applied via foliar spray, trunk injection, soil drench, or basal bark spray. For larger trees, trunk injection is a primary method, while foliar sprays are used for broader coverage. When handling, users must wear personal protective equipment (PPE) including chemical-resistant gloves, long sleeves, long pants, and sturdy shoes. It is important to avoid contact with eyes and skin. The label provides specific dilution rates and application methods based on the target pest, plant type, and tree size.
