Product Information

Potassium Phosphite a liquid fertiliser containing fast-acting, highly mobile phosphite (PO3) molecules, which move systemically via the phloem and xylem to the leaves and roots, rather than the usual phosphate (PO4).
Its effect is to increase the rate of energy transfer within the plant, resulting in increased root and shoot initiation and development, it also has fungicidal properties.

  • Disrupts the phosphorus metabolism in the pathogen, inhibiting its growth and causing it to release stress molecules with the consequent activation of the hosts defence responses.
  • Stimulates and supports natural tree defence mechanisms encouraging the nucleus of the trees cells to produce defensive molecules.
    1. Photoalexin is produced which attacks the disease directly, phosphite also helps maximise this by providing ideal nutrition.
    2. Encourages the production of polysaccharides which strengthen the cell walls, giving additional protection.
    3. Causes the cells also to send "alarm signals" to cells that have not yet been attacked.
  • Relieves ‘hidden phosphorus hunger’ during fast growth stages.
  • Stimulates healthy growth during conditions which may be favourable to the development of some root rots and leaf mildew.
  • Complements the action and mobility of other nutrients such as manganese and iron.
  • Acts as a vehicle for the absorption of calcium by the roots, the improved movement of this normally ‘immobile’ nutrient around the tree is thought to play a key role in tissue strengthening. Calcium is needed to make calcium pectate, the cement-like substance which holds plant cells together.
  • Non persistent in the environment, as readily oxidised to phosphate by soil microbes, and also has very low mammalian toxicity.

A quick way to calculate the approximate diameter of a tree is to pass a tape measure around the tree and then divide the resulting figure by 3.
