Phosgard products are plant nutrition for soil or foliar applications. The phosphorus contained in Phosgard 0-28-25 is less oxidized than other commonly available high P products, which provides the plants you grow with more readily available P. Utilizing JH Biotech's patented phosphite technology, plants quickly take up ready to absorb phosphite. Once absorbed, plants then convert the phosphite into usable phosphate. By this process, Phosgard 0-28-25 improves crop maturation, root development, flowering and fruiting, and crop quality. Phosgard® 0-28-25 stimulates plants’ natural immune systems helping them prevent disease.
