PRIMAZEST
For Floriculture, Annual & Greenhouse Crops
+ early-season vine and tree crops, new plantings and grafts.
Less Stress. Less Damage. Better Crop Quality.
Not a fertiliser. Not a hormone. Not a generic biostimulant.
A unique New Zealand–made elicitor of the phenylpropanoid pathway that activates your crop’s repair, growth and defence systems — reducing pest, disease and environmental stress to deliver higher quality harvests.

How Primazest Works + Why its Different
Primazest doesn’t feed plants — it activates the phenylpropanoid pathway — the system that drives plant defence, growth and crop quality.

Backed by Science
There is no other product “just like Primazest”. The technology was developed by us and has been tested and proven in multiple districts, seasons, and crops.
Primazest is an entirely new technology (an elicitor of the phenylpropanoid pathway) that enables a big leap forward in productivity.
Phenylpropanoids are naturally produced by all plants & are responsible for plant and fruit quality characteristics, e.g. lignin and suberin to harden cells and produce crunchier fruit, flavonoids for improved flavour, anthocyanins for high colour and coumestrol and other oils to repair damage. Phenylpropanoids support the repair, growth and defence systems of plants.

The science of phenylpropanoids and the plant response to Primazest is covered in our paper, which has been published in a peer-reviewed scientific journal https://rdcu.be/cGRgc.
🌦 Protect & Strengthen
→ Reduce pest, disease and environmental stress
→ Faster recovery, less damage
→ Stronger, more resilient plants
The Result
Less stress. Less damage. Better quality.
Higher returns per hectare from healthier, more productive crops.
🌸 Improve Quality & Yield
→ Better colour and flavour
→ Improved consistency and finish
→ Fewer defects and rejects
Why Primazest Is Different
Not a fertiliser (doesn’t supply nutrients)
Not a hormone (doesn’t force growth)
Not a microbial product
No residue, no withholding, no GM
An elicitor of the phenylpropanoid pathway that activates the plant’s own systems to reduce pest, disease and environmental stress — improving crop quality and yield.
Where Primazest Fits
🥝 Tree & Vine Crops (Kiwifruit, Grapes, Apples)
Targeted use during high-stress periods (typically early season/grafts)
→ Early spring growth
→ New Plantings or grafts
→ Pre-production vines and trees
→ Times of expected pest, disease or environmental stress
Result: Stronger early development → better crop potential later
🌱 Annual, Greenhouse & Floriculture Crops
Used throughout the growing cycle
→ From early growth stage to harvest
→ Ongoing production cycles
→ Any period of stress or quality risk
Result: Cleaner crops, higher quality, high returns.
Fits into Your Existing Programme
🌱 No wetting agent required
🌱 Typical water rates of 500-1,000L/Ha or 5ml/L in knapsack sprayers
🌱 Primazest is compatible with most commonly used orchard sprays.
🌱 Compatibility with additional products must be tested prior to application.
🌱 Do not mix with copper or hormones including Actiguard and CPPU.
Primazest is not a hormone spray, fortified seaweed or fertiliser and does not leave any residue.
Primazest is Kiwi owned and has been developed, manufactured and tested in New Zealand by New Zealand growers for all New Zealand crops.
Application Programme
Application Overview:
Typical rate:
5ml/L (knapsack / greenhouse)
1L/ha (large scale spraying)
🥝 Tree & Vine Crops
Start from 2-leaf stage
Apply every 7–14 days during early growth
Transition to Agrizest 3 weeks before flowering
🌱Vegetable and Agricultural Crops
2 sprays early (3–5 days apart)

Grower Results
BEFORE
AFTER
“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. “
