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:
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
