Plant Defense Activators
PHOSGUARD INFINITY
PHOSGUARD INFINITY is the premium grade in the range, combining phosphite with copper supplied as a highly available gluconate complex, plus potassium and nitrogen. The readily available copper reinforces the phosphite’s defence activity and corrects deficiency, while the nitrogen and potassium support active growth. It is built as a preventive tool, used to prepare and […]
PHOSGUARD B-Zn
PHOSGUARD B-Zn is the flowering-stimulation grade, a high-potassium phosphite that carries boron and zinc into the reproductive phase. The potassium load supports the sugar movement that fills and finishes fruit, while boron and zinc work on pollen viability, fertilisation, and the auxin balance behind flower development. Systemic phosphite runs alongside as plant-health support through flowering […]
PHOSGUARD MICRO
PHOSGUARD MICRO is the multi-nutrient grade, a liquid potassium phosphite that carries boron, manganese, molybdenum, and zinc alongside its defence activity. It is designed for crops that show several micronutrient shortfalls at once, correcting them in available form while the systemic phosphite supports the plant’s own defences. Rather than feeding a single element, it restores […]
PHOSGUARD Zn-Mn
PHOSGUARD Zn-Mn is the zinc and manganese grade, a liquid phosphite built around two of the most common early-season micronutrient deficiencies. It carries high levels of zinc and manganese in available form, supporting vigorous vegetative growth while the systemic phosphite adds defence support over the same window. Zinc drives the auxin and protein synthesis behind […]
PHOSGUARD AL
PHOSGUARD AL is the aluminium phosphite grade, formulated for the most demanding oomycete situations. Pairing phosphite with aluminium gives this liquid an additional direct effect against organisms such as Phytophthora and the downy mildews, on top of the systemic defence response the phosphite primes in the plant. Fully systemic, it carries that protection to both […]
PHOSGUARD CU
PHOSGUARD CU is the copper-carrying grade, a liquid that pairs phosphite with copper for crops facing the heaviest disease pressure. Copper complements the phosphite’s defence activity and, as a nutrient, corrects deficiency and supports the lignification that builds stronger tissue. The combination is aimed at vines, olives, citrus, and other woody and perennial crops where […]
PHOSGUARD CALCIUM BO
PHOSGUARD CALCIUM BO is the flowering and fruit-set grade, a liquid phosphite that carries calcium and boron into the reproductive stage of the crop. Where the base grades lead on defence alone, this one pairs systemic plant-health activity with two elements that govern successful flowering and fruit development: calcium for cell-wall integrity and fruit firmness, […]
PHOSGUARD WSP
PHOSGUARD WSP is the most concentrated phosphite in the range, supplied as a fully soluble off-white powder rather than a liquid. At 96% potassium phosphite, it puts the highest phosphite and potassium loading into the smallest, lightest package, which suits dry storage, lower freight, and precise blending into custom programmes. Dissolved in water it behaves […]
