General Information


Super Foliar Phosphite is a formulated treatment for Nitrogen, Phosphate and Potash deficiencies in a wide range of vegetable, permanent and ornamental crops and in turf. Applications of Super Foliar Phosphite can be beneficial to plant growth, including root development, flowering, and transplant establishment. This product may be applied through various application equipment and techniques, including air, ground and conventional sprayers. This product and other phosphorous acid products are intended to be used as a supplement to a well-balanced fertilizer treatment program. It is not intended to be a substitute for sound soil fertilization and conventional cultural practices. Thorough coverage of foliage is necessary for best results when used as a foliar treatment.

Upon foliar application, the phosphite ions are taken up directly by the plant foliage and may undergo a degree of conversion to phosphate ions, or will be used directly by the plants as phosphite ions. Avoid foliar application under extremes of climate, e.g., rapid drying conditions, extremely slow-drying conditions, frost, rain, or when frost or rain are anticipated. As a soil application to annual crops, a lesser response from the initial crop, with a corresponding superior response from succeeding crops, may be observed. In addition, placement close to seeds or root zones may be injurious to crops. The effect may be aggravated by a soil pH below 6.5. For additional information on product or programs or if you are unfamiliar with any of the application methods, contact your local Helena Chemical Company representative or authorized Helena dealer.

It is not recommended to use additional surfactants and/or adjuvants with this product.


Precaution: Super Foliar Phosphite is a highly-concentrated material. Exercise precautions to prevent potential root or foliar injury (including burning), plant media Ph changes, irrigation system or injection system damage. If applying Super Foliar Phosphite in combination with other materials, a compatibility test is recommended to avoid potential incompatibilities. Prior to the addition of Super Foliar Phosphite to a spray mix, the user or application advisor must have experience with the combination or must have conducted a phytotoxicity trial. Do not mix with fixed-copper or copper-based fungicides if the pH of the spray solution is below 6 pH. Use sufficient water to ensure thorough coverage.

It is not recommended to use additional surfactants and/or adjuvants with this product.
