KiwiVax®

Wettable Powder Root Drench for the reduction of Psa symptoms in Kiwifruit vines

Kiwivax is a BioGro certified Root Drench for Kiwifruit.

Developed in partnership with the Bio-Protection centre at Lincoln University, Kiwivax is a wettable powder for use in the nursery and the open orchard.

The trichoderma in Kiwivax have been shown to be endophtic, entering the roots of the plant, penetrating a couple of cells deep and switches on the plants defence mechanism.

The trichoderma release enzymes which stimulate root growth. In the nursery this helps to produce a stronger, healthier root system resulting in Increased nutrient uptake, photosynthesis and vigour.

In the open orchard, these roots enable to vine to withstand environmental and disease stresses.

Kiwivax is a root application designed to be direct sprayed on to rootzone.
