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 shield crops ahead of anticipated disease pressure rather than to react to it. The grade fits preventive foliar and fertigation programmes on high-value vines, fruit, and vegetable crops.

Key Benefits

• Prepares the crop’s defences ahead of pressure. Phosphite primes phytoalexin and phenolic synthesis and cell-wall reinforcement, putting the plant’s defences on alert before disease arrives.
• Adds a direct protective effect through copper synergy. Copper supplied as gluconate complements the phosphite, reinforcing the protective profile in preventive programmes.
• Corrects copper deficiency in available form. The gluconate complex keeps copper readily available for uptake, addressing shortfalls in prone crops.
• Supports active growth. Nitrogen and potassium feed vegetative development and quality alongside the defence activity.
• Moves systemically through the crop. Full translocation distributes the activity and nutrients to new growth the spray never directly wets.

How It Works

PHOSGUARD INFINITY delivers phosphite, the phosphonate ion, which crops absorb quickly and move systemically through both xylem and phloem after a foliar spray or fertigation application. Inside the plant, phosphite acts in two complementary ways that depend on concentration. At higher local concentrations it is directly unfavourable to oomycete organisms such as Phytophthora, Pythium, and the downy mildews, slowing their growth and energy metabolism. At lower concentrations it primes the crop’s own defence system, triggering the synthesis of phytoalexins and other phenolic compounds, reinforcing cell walls with lignin and suberin, and raising the activity of defence-related enzymes. Because it is fully systemic, the protection reaches new growth and tissues the spray never directly contacted.

This grade combines phosphite with copper supplied as gluconate, a highly available organic complex, plus potassium and nitrogen. The readily available copper corrects deficiency and complements the phosphite’s defence activity, while the nitrogen and potassium support active growth. It is built as a preventive tool, used to prepare and shield crops ahead of anticipated disease pressure rather than after it.

When to Use PHOSGUARD INFINITY

PHOSGUARD INFINITY is a preventive grade, applied to prepare and shield crops before pressure builds.

• Apply PHOSGUARD INFINITY preventively, ahead of anticipated fungal and bacterial pressure.
• Use PHOSGUARD INFINITY where copper correction and strong preventive defence support are both wanted.
• Include PHOSGUARD INFINITY in foliar or fertigation programmes on high-value vines, fruit, and vegetable crops.

Plants mount their strongest defences when they are healthy and unstressed; when a crop is under pressure those responses slow, which is exactly when systemic support earns its place. Applying ahead of and through high-pressure periods keeps the crop’s defences primed when it cannot fully prime them on its own.
