Free Courier Delivery, No Account Required
An innovative spray for optimal plant health, crop quality and sustainable yield.
For Floriculture, Annual and Greenhouse Crops
+ early season kiwifruit, pre-production vine and tree crops, new plantings and grafts.
Increase Plant Health & Performance
Primazest is a liquid spray that reduces damage caused by pest, disease or environmental stress. Primazest ensures healthy, sustainable production.
Benefits include:
increased, healthy growth
higher quality crops
improved colour development
reduced pest damage
increased saleable yield
Increase Crop Quality & Yield
Primazest helps you produce high yields and high-quality crops. Primazest improves fruit size, colour & flavour; flower colour, size & stem length and overall plant growth.
For Kiwifruit and other tree/vine crops: Primazest is specifically formulated to reduce stress from copper application or adverse weather conditions and to support energy production during early growth stages.
Primazest encourages robust and healthy growth of new grafts and helps you quickly establish a full canopy to set you up for a productive first crop.:
Cost Effective
Primazest significantly increases returns due to higher quality and sustainably high yields. Primazest supports a return to healthy, productive growth.
Primazest can also reduce costs: Primazest improves recovery and reduces damage caused by pests such as mites and, as a result, can reduce pesticide applications and associated costs. This is a significant cost saving for the grower. Note: Primazest has no direct effect on pests or diseases.
For All Kiwi Crops
Primazest is authorised by MPI (under the ACVM Act) as exempt from registration and can be used on all crops.
Primazest is certified by BioGro for use in organic production (5943).
Primazest is included in the Zespri ‘Other Allowed Compounds' (AOC)’ list and can be added to your spray calendar.
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.
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, flavanoids 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.
Commercial Gerbera Operation, Auckland
“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. “

DIRECTIONS
KIWIFRUIT
New Orchards and New Grafts in Established Orchards:
From the 2 leaf stage onwards:
Rate: Primazest at 5ml/L with a knapsack sprayer
Timing: every 3-7 days.
When growth has reached the stage where a sprayer with directed nozzles is necessary:
Rate: Primazest at 5ml/L,
Timing: every 7-14 days.
With an almost full canopy (and when more than 200L of water is needed to cover 1 hectare):
Rate: Primazest at 1L/ha with an air blast sprayer
Timing: every 14-21 days until full canopy is achieved.
Vegetable and Agricultural Crops
Rate: use 1 litre of Primazest in 50 to 500 litres of water per hectare.
Timing: at early growth stage apply 2 sprays, 3 to 5 days apart.
Then a further 2 sprays, 2 weeks apart.
Please contact us for further instructions specific to your crop.
Greenhouse Crops
Rate: use 5mls of Primazest per litre of water.
Timing: at early growth stage apply 2 sprays, 5 days apart.
Then a further 2 sprays, 2 weeks apart.
Follow on sprays can be applied when pest, disease or environmental pressure is anticipated.
Near harvest, apply weekly to maintain clean crops.
KIWIFRUIT
Established Orchards:
For early season growth. To protect, reduce stress and aid recovery from variable spring conditions such as frost and high winds.
Rate: 2 sprays of Primazest at 1L/ha.
Timing: 7 days apart starting at the 2 leaf stage (around 4cm) and until 2-3 weeks before flowering (before the 1st Agrizest spray is applied).
User Guidance
No wetting agent required
>Water rates: dependent on sprayer & canopy – ensure product application rate is 1litre per hectare with typical water rates of 500-1,000 per hectare
>Compatibility: 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.
>Please read the product labels thoroughly before use.
Introduction to the Science
For detailed scientific information please read the paper published in a peer-reviewed scientific journal.
How Does Primazest Work?
Primazest works indirectly to elicit phenylpropanoids to reduce stress and increase plant performance.
All plants have receptors on their surfaces. Rather than directly feeding the plant or targeting a specific pest or disease, Primazest is designed to be registered by these receptors, eliciting, or triggering, a plant response.
Primazest is manufactured from various plant-derived materials. Proteins, fats and phospholipids are extracted and re-formed so that, when applied to plants, they mimic the attack of pest, disease and environmental stress without causing any damage to the plant. The plant reacts to Primazest applications by producing Phenylpropanoids.
Primazest is not a hormone spray, fortified seaweed or fertiliser and does not leave any residue.
Introduction to Phenylpropanoids
Phenylpropanoids are a range of bioactive molecules, naturally produced by all plants, responsible for important plant and fruit quality characteristics. They also support plants' repair, growth and defence systems (immune systems).
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.
