“Primazest has changed the way we grow. After having ongoing pH problems our plants became very sick and Primazest was the only product that was able to bring them back to full health. We have noticed so many benefits since using this product. Longer stem length, larger flowers, brighter colours & healthier plant growth. “

 How Does Primazest Work?

  • Phenylpropanoids are a range of bioactive molecules, naturally produced by all plants, they are responsible for important plant and fruit quality characteristics.  They also support the repair, growth and defence systems of plants.
     

  • Examples include lignin and suberin to harden cells and produce crunchier fruit, flavanoids for improved flavour, anthocyanins for high colour and coumestrol and other oils to repair damage.
     

  • When Primazest is applied to plants it triggers and elicits the production of these molecules, ultimately enabling optimal plant health and fruit quality.
     

  • Primazest is not a hormone spray, fortified seaweed or fertiliser and does not leave any residue.

    "We have grafted to G3 and used Primazest once the grafts had taken. We have a 70 percent canopy and the orchard is looking good.”​
