Floriculture and
Annual Crops
Stronger plants. Less stress. Higher-quality crops.
PRIMAZEST FOR FLORICULTURE & ANNUAL CROPS
Not a fertiliser. Not a hormone. Not a generic biostimulant.
A better way to grow.
Primazest is a New Zealand–developed elicitor of the phenylpropanoid pathway, designed for:
Floriculture
Greenhouse Crops
Strawberries, Vegetable and other Annual Crops
Native, Ornamental and Forestry Nurseries
It helps plants handle pest, disease and environmental stress, recover faster, and build the compounds that drive growth, quality, and resilience.
What That Means For Your Crop
Primazest helps plants build strength and performance from the start.
You’ll see:
Faster, more even establishment
Stronger, more uniform plants
Improved colour, size, and overall crop quality
Reduced damage from pest, disease, and environmental stress
Higher percentage of saleable product
Primazest consistently improves growth, quality, and yield in soft tissue crops like flowers, strawberries, and vegetables.
Growers Report:
“We are now picking tomatoes with great results, great flavour, good crop of good fruit. Our last crop didn't have the Primazest treatment and we lost approximately 1/4 of the crop, now I probably discard at most 6 tomatoes per picking”

Why Growers Use Primazest
Annual and greenhouse crops are highly sensitive:
Stress shows up immediately (temperature, moisture, pH, spray damage)
Early setbacks reduce final yield and quality
Pest and disease damage directly impacts saleable product
Primazest helps crops get through this phase stronger, cleaner, and more productive.
How It Works
Primazest activates the plant’s internal phenylpropanoid pathway — the system responsible for producing key compounds involved in plant health, foliage and fruit quality, for example:
Cell strength and structure (lignin)
Colour and visual quality (anthocyanins)
Flavour and plant protection compounds (flavonoids)
Natural defence and recovery responses
Rather than feeding the plant, it triggers a response — helping the plant:
Grow stronger.
Recover faster.
Perform better under pressure.
Proven in Production
Growers consistently report:
Faster growth and earlier crop development
Stronger plants with improved vigour
Reduced pest and disease damage
Higher production and better quality outputs
In floriculture trials:
+14% increase in flower production
Maintained stem length under stress conditions
Healthier plants with improved visual quality
Growers report:
“Longer stem length, larger flowers, brighter colours & healthier plant growth.”
“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“
