Vinevax Natural Bioimplants are a cost effective long term treatment for your valuable vines.
Vinevax Bio-dowel is a biological agent that contains selected proprietary Trichoderma strains formulated as a slow-release implant for the prevention and treatment of diseases caused by wood-invading trunk pathogen in grapevines and fruit trees.
Independent research shows that Vinevax is still protecting the vine even after 4–5 years.
Protection of healthy vines
Drill a hole at a slight upward angle 28mm deep x 6mm diameter into the trunk below the cordon and insert one Bio-implant.
Treatment of diseased vines
For mild disease which only affects the
cordon: Drill the hole into clean trunk wood below the cordon and insert 1 Bio-implant. Cut-off affected cordon wood.
For severe disease which has spread into the main trunk
Drill the hole into clean wood as close as possible to ground level or 25 to 50mm below the position of a water shoot suitable for reconstruction of the vine. Apply 1 Bio-implant per vine.
Tips for Use
Avoid treatment during sap flow in late winter/early spring.
What is it and how does it work?
Vinevax Bioimplants have been shown to colonise around the parenchyma cells of the vine pith where they inoculate the grapevine tissue and stimulate the natural defense mechanisms of the vine.
This produces a “vaccination” effect that enables the vine to become more resistant to disease and divert its energy into grape production.
Proven Disease Protection
Vinevax bio-dowels protect vines from infection by pathogens causing vascular trunk diseases such as Eutypa die-back that lead to production losses and eventual vine death.
Cost Effective
Numerous case studies have proven the cost benefit of bio-dowels. Because application reduces the incidence of vascular trunk diseases and improves vine health, longevity and productivity your investment will be paid back many times over.
Safe and Sustainable
Vinevax bio-implants are a safe and organic. There are no residues, MRL’s or withholding periods.
Long Lasting Protection
Vinevax bio-implants protect your vines for 4-5 years. Re-application is not required.

The True Cost of Eutypa Dieback
Eutypa dieback, caused by the fungus Eutypa lata, is a major disease of grapevines worldwide and causes considerable economic loss to the wine industry.
The fungus infects exposed pruning wounds, colonising the cordons and trunk resulting in stunted shoots and disfigured and uneven bunches and eventually death of the vine.
Once established in vines, the only method of controlling Eutypa dieback is through the removal of all infected wood tissue using remedial surgery.
In 1999, Trevor Wicks reported yield losses in Shiraz vineyards could be up to 1500kg/ha which might conservatively be valued at $3000 NZD.
Vinevax Bio-Dowels can be used at all stages of disease expression to promote vine health.
Trial Results
Increased vine vigour
In a trial using just a single dowel per vine, the treated vines at Kaesler, Taylors and Henschke Wines showed marked bunch increases, providing additional fruit valued at at least $2500 per hectare.
Grapevine health after vine reconstruction
In cases of severe Eutypa dieback, it can be necessary to remove the original trunk to eliminate all infected tissue. A single Vinevax Bio-Dowel placed at the base of a watershoot, trained up to form a new canopy protects the new growth.
The health of reconstructed vines in one study was graded on a scale of 0 to 3, ranging from full health to dead vine.
The overwhelming majority of vines displayed no dieback symptoms after treatment.
Symptom reduction
In mild cases of Eutypa dieback (i.e. main trunk removal not needed), Vinevax Bio-dowels can still be applied to increase vine vigour, yield per vine and total bunches.
In one study using symptomatic vines treated with VineVax Bio-dowels, disease severity was graded on a scale of 0 to 5, ranging from health to dead vine. VineVax Bio-Dowels significantly reduced disease severity, leading to greater vine productivity.
