How Biozest Works - And Why its Different
-
BACKED BY SCIENCE. BUILT FOR A STEP-CHANGE.
There is no other product like Biozest.
Developed in New Zealand and proven across multiple regions, seasons, and farming systems, Biozest represents a new approach to productivity — not just another input.
For decades, gains in agriculture have come from incremental improvements. But real step-changes require new technology.
Biozest is exactly that.
A NEW WAY TO LIFT PERFORMANCE
Biozest is an elicitor of the phenylpropanoid pathway — a natural system present in all plants that drives growth, repair, and defence.
Phenylpropanoids are responsible for key plant functions:
Stronger plant structure (lignin, suberin) → tougher, more resilient pasture
Improved quality compounds (flavonoids) → better feed quality
Natural defence systems → faster recovery from stress
Result: Pasture that grows stronger, performs under pressure, and delivers higher-quality feed.
WHY THIS MATTERS FOR LIVESTOCK
Ruminants typically convert only ~25% of pasture into milk and meat.
The rest is lost as waste — including nitrogen (urea) and emissions.That’s a massive efficiency gap.
Biozest-treated pasture changes this:
Higher-quality feed
Better utilisation by stock
More milk and meat
Less nitrogen loss and environmental impact
More production. Less waste. Higher efficiency.
PROVEN SCIENCE. REAL-WORLD RESULTS.

A DIFFERENT APPROACH
Biozest doesn’t feed your pasture — it activates it.
Not a fertiliser. Not a microbial. Not a hormone.
A breakthrough technology that improves plant and livestock performance from the inside out.
Biozest doesn’t feed your pasture. It switches it on.
Biozest activates the plant’s phenylpropanoid pathway — triggering natural processes that drive strength, resilience, and feed quality from within.
Activate → Grow → Convert
🚜 Activate
Plants switch on their own growth, repair, and defence systems.
🌱 Grow
More resilient, dense, high-quality pasture
🫗 Convert
More milk and meat, less waste.
Why it’s different
Not fertiliser.
Not hormones.
Not microbes.
No GM.
A switch.
Biozest works with the plant to unlock performance.
Developed, tested, and proven on Kiwi farms.
Cut nitrogen loss and methane without cutting productivity.
Urea and methane aren’t just waste, they’re lost profit and a red flag for regulators.
Biozest reduces both, by improving how well pasture grows and how efficiently animals use it. Less nitrogen leached, fewer emissions, and more weight or milk in the vat.

-
Strategic Programme (Dairy)
Start with two applications, then use as needed to maintain feed supply, manage stress (e.g. drought or frost), and lift pasture quality and yield.
Application guide:
Rate: 1 L/ha (in 20–500 L water)
Start: 2 sprays, 3–5 days apart
Ongoing: Apply seasonally or as conditions require
Hay & Silage:
Apply twice before paddock lock-up.For second cuts, reapply 3–5 days after the first cut.
Full Programme (Dairy Pasture)
For maximum, year-round performance in pasture growth, feed quality, and milk/meat production, a full programme is recommended.
Application guide:
Rate: 1 L/ha (in 20–500 L water)
Start: 2 sprays, 3–5 days apart
Ongoing: Apply 3–10 days after each grazing
Which programme is right for you?
Choose Strategic if you want to:
Respond to feed shortages or pinch periods
Support pasture through stress (dry, cold, recovery)
Boost specific events like baleage or silage
Trial Biozest with lower upfront commitment
Choose Full Programme if you want to:
Drive consistent, year-round pasture performance
Maximise feed quality and utilisation
Support milk/meat production at a system level
Build resilience and reduce variability across the season
Simple rule of thumb
Strategic = reactive, targeted use
Full programme = proactive, system-wide performance -
Hay & Silage Production
Boost dry matter and yield with targeted applications.
Application guide:
Rate: 1 L/ha (in 20–500 L water)
Apply 2 sprays before paddock lock-up
For second cuts, reapply 3–5 days after the first cut
Beef, Sheep & Deer Farms
Support consistent pasture performance and feed quality across the season.
Application guide:
Rate: 1 L/ha (in 20–500 L water)
Start: 2 sprays, 3–5 days apart
Ongoing: Apply once per season (spring, summer, autumn, winter) or as required
Stock Finishing Paddocks
For higher-performance paddocks where feed quality and utilisation are critical.
Application guide:
Rate: 1 L/ha (in 20–500 L water)
Start: 2 sprays, 3–5 days apart
Ongoing: Apply 3–5 days after each grazing
Choosing the right approach
Hay & Silage: maximise yield and dry matter
General grazing: maintain steady pasture performance
Finishing paddocks: drive higher animal performance from premium feed
