Phytomax Fost – Potassium Phosphite — Dual-Purpose Fetilizer
Dual-Purpose Fetilizer

Phytomax Fost – Potassium Phosphite

This fertilizer simultaneously supplies potassium and phosphorus required by plants. With its phosphorous acid content, it enhances plant resistance to fungal diseases such as downy mildew, blight, root rot, gummosis, and collar rot in fruit trees, both directly and indirectly. The phosphorus in this formulation is present as phosphite, which contains one less oxygen atom than phosphate, making the molecule smaller, more mobile, and rapidly translocated throughout plant tissues.
