KIWIFRUIT
Optimal plant health. Fruit quality. Sustainable yield.
An Elicitor of the Phenylpropanoid Pathway
No two orchards are the same — but the same challenges show up every season:
Maintaining healthy vines
Managing stress through spring variability
Achieving consistent fruit size, dry matter, and colour
Reducing rejects and improving pack-out
That’s where the Agrizest programme shines.
Stronger cane replacement
Improved fruit quality (dry matter, colour, flavour)
Reduced damage cause by pest, disease and environmental stress
More resilient, productive vines season after season
Switch the Vine On
Agrizest and Primazest don’t feed the plant — they activate it.
They trigger the plant’s natural phenylpropanoid pathway — driving:
The result:
Stronger Vines. High Quality Fruit. Reduced Rejects. Higher Yield. Higher OGR
Agrizest is not a foliar or seaweed fertiliser or a hormone.
It’s a new generation of bio-stimulant that triggers the vine’s natural repair, growth and defence system, preparing it to respond before stress becomes visible.
By activating natural defence pathways, vines stay healthier, stronger, and more productive.
Pair with Primazest for an early spring boost and set your vines up for a healthy, productive season.
You’ll optimise vine health, flowering, and fruit quality, giving you more control over your crop’s performance, naturally.

“The results were immediate. The vine, leaf, overall health was just phenomenal”

Proven Where it Matters - Kiwifruit
Zest products have been used in the kiwifruit industry for over 15 years.
🥦 Not adapted from other crops
🛬Not imported for a quick buck
Developed alongside real growers, in real orchards.
You may hear other products are “just like Zest.”
They’re not.
Zest is built on a unique phenylpropanoid elicitor approach, proven repeatedly on kiwifruit orchards — not just in theory.
We keep things simple:
We only have four products.
So they have to work.
Large companies can move on to the “next big thing” if one underperforms.
We don’t have that option - and we don’t need it.
Performance is proven season after season.
