Primazest is formulated for early kiwifruit growth, annual crops, flowers and other soft tissue plants. For vine and tree crops such as kiwifruit, grapes, apples and other deciduous trees use Agrizest.

“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. “

What is Primazest?

Primazest is formulated for early season kiwifruit growth and to improve quality & yield in annual crops and soft tissue plants such as cut flowers and strawberries.

  • Early Growth Kiwifruit

  • Cut Flowers

  • Annual Crops

Using Primazest encourages:
• Healthy growth
• Reduced damage
• Recovery from stress caused by variable weather
conditions such as high winds, heat, drought and frost

For 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 is authorised by MPI (under the ACVM Act 1997) as exempt from registration and can be used on all crops with nil withholding period & nil waiting period.

  • Primazest is included in the Zespri 2018/19 Allowed Other Compounds (AOC) list and can be added to your spray calendar.

  • Primazest is certified by BioGro for use in Organic Production.

How Does Primazest Work?

  • When Primazest is applied to plants it triggers and elicits the production of bioactive molecules called phenylpropanoids which enable optimal plant health and fruit quality.

  • 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.

  • Primazest is an elicitor - it is not a hormone spray, fortified seaweed or fertiliser and does not leave any residue.

  • Primazest is formulated specifically for soft tissue crops such as annuals and early season vine growth.


Primazest - For Kiwifruit And Annual/Softwood Crops

Standard Kiwifruit Programme

Primazest is applied from the 2-leaf stage.

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.

Using Primazest encourages:
• Healthy growth
• Reduced damage
• Recovery from stress caused by variable spring
conditions such as high winds and frost

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).

Follow with 4 sprays of Agrizest

Please contact us if you have any additional questions.

For Newly Grafted Kiwifruit Orchards and New Grafts in Established Orchards:

Use Primazest in newly grafted kiwifruit orchards and on new grafts within established orchards to encourage healthy (not rampant) growth and to help bring new kiwifruit varieties into production.

From the 2 leaf stage onwards:

Rate: 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: 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: 1L/ha with an air blast sprayer

Timing: every 14-21 days until full canopy is achieved.

For other softwood crops:

Primazest improves the yield,quality, colour, flavour and nutritional value in softwood and garden crops.

Primazest helps plants to naturally resist stress and damage while lifting productivity to substantially and sustainably increase returns.

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.

Please contact us for further instructions specific to your crop.

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 & Agrizest are 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.
