Primazest FAQ

Primazest is a unique Kiwi technology proven to increase plant health and orchard gate returns (OGR) in New Zealand orchards and gardens for over 10 years.

Primazest is an elicitor (or a trigger) of the phenylpropanoid pathway, it increases plant health and productivity by evoking and strengthening the plant’s immune system.

Primazest helps plants naturally resist stress and damage and improves growth, resilience, fruit, vegetable and flower quality and yield.

In flower production, for example, Primazest increases stem length, colour intensity and flower size. 
In cabbage production Primazest reduces pest damage and significantly increases marketable yield.

Primazest is manufactured from plant extracts, fatty acids, phospholipids, plant compatible organic acids & wetting agents.

Primazest is not a seaweed fertiliser, microbial brew or fermented product.

Primazest works indirectly to elicit phenylpropanoids to reduce stress and increase plant performance.

All plants have receptors on their surfaces so, rather than directly feeding the plant or targeting a specific pest or disease, Primazest is designed to be registered by these receptors which then elicits, or triggers, 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 actual damage to the plant. The plant reacts to Primazest applications by producing Phenylpropanoids.

Phenylpropanoids are a range of bioactive molecules, naturally produced by all plants, responsible for important plant and fruit quality characteristics. They also support the repair, growth and defence systems (immune systems) of plants.

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 vegetable/flower/fruit quality.

Primazest is not a hormone spray, fortified seaweed or fertiliser and does not leave any residue.

In kiwifruit Primazest is specifically formulated to reduce stress from copper application or weather conditions such as frost or high winds and to support energy production during early growth stages.  Primazest helps you quickly establish a strong, healthy canopy and get the best start to the season.

In greenhouse and outdoor annual crops benefits include increased flower size, colour intensity and stem length; reduced pest damage; improved drought/heat /frost resilience and recovery; increased fruit yield, size, colour and flavour.

Overall improved plant health, marketable yield and increased returns.

Primazest is $37.5+GST per litre. 

Kiwifruit
1. Early Season Growth on Producing Vines: The application rate is 1 litre per hectare and should be applied 2-3 times beginning when the leaves reach the size of a golf ball until the first Agrizest application (3 weeks before flowering).

2. Grafts/Newly Established orchards:

From the 2 leaf stage onwards apply 5ml/L with a knapsack sprayer every 3-7 days.

When growth has reached the stage where a sprayer with directed nozzles is necessary apply 5ml/L every 7-14 days.

With an almost full canopy (and when more than 200L of water is needed to cover 1 hectare) apply 1L/ha with an air blast sprayer 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.

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. At harvest, apply weekly to maintain clean crops.

You can order Primazest directly from us. You can order by phone or email but the best way to order is online – you don’t need a credit card or Paypal account (although these are both options). We will send you an invoice and our payment terms are 20th of the month following your order.

Please get your orders in early so you can apply Primazest on time to ensure the best results.

No.

Merchants may say they have a product that is the same but we advise you to check their claims, data and the cost of these products in their country of manufacture (Primazest is manufactured by us here in NZ).

No.

Primazest does not directly feed the plant. Seaweed is just one of the plant extracts we use but it is a small percentage of the product.

We have heard of a number of merchants selling products as “just like Primazest/Agrizest/Biozest”. We have tested some of these fertilisers against Agrizest. Agrizest has significantly outperformed the other products in trials.

Primazest is a unique product, developed by us here in NZ, manufactured by us in NZ and tested and proven on Kiwi crops.

• Kiwifruit grafts and early season growth.

• Cut flower production such as roses, chrysanthemums, gerberas, tulip, gypsophilia, lilies and carnations.

• Annual crops such as strawberries, chilies, capsicums, tomatoes, etc.

For arable crops we recommend Biozest.

Yes.

Primazest has been classified by the Ministry of Primary Industries – MPI – (ACVM Group) and is exempt from registration.

For kiwifruit: Primazest is included in the Zespri Allowed Other Compounds (AOC) list and can be added to your spray calendar.

All of our products are approved by BioGro as inputs for organic production.
