Fos line is a family of liquid fertilizers of high quality, with the peculiar presence of phosphorus in the form of phosphite ion that plays both a nutritional and protective systemic role. The action of phosphite ion inside the products of Fos line also stimulates a higher production of phytoalexins (natural defensive substances) in the plant thus permitting a biological induced protection.
