Turf and Pasture
At Biostart, we have created a biostimulant range that activate naturally occurring soil and plant microbes that are critical for nutrient uptake and optimising pasture and turf health.
How our range works
Optimal soil biology, rapid breakdown of browntop thatch and control of NZ Grass Grub ensures healthy pasture and turf. Our biostimulant products are compatible with many nutritional and pest and disease control products so can be easily added into any current programme.
Pasture that has been treated with ThatchBusta.
|Pasture trial sheet
An independent pasture trial was conducted in Spring 2020, it found that applying Biostart N and Mycorrcin led to greater long term pasture growth while reducing the amount of urea required by half, over a four month period.
|ThatchBusta Case Study
Browntop thatch covers top soil, choking out ryegrass and clover. Use ThatchBusta to convert thatch into humus and promote clover growth.
|BioShield Technical Sheet
A description of how BioShield reduces pasture damage by NZ Grass Grub and how to identify NZ Grass Grub.
How to use our products
Biostart N contains a Nitrogen fixing bacteria (Azotobacter chroococcum) that creates plant available nitrogen in the soil, reducing the need for other nitrogen fertilizer. Mycorrcin ensures the successful establishment of the Azotobacter chroococcum in the soil.
|New pasture at sowing
|Apply 100 mL/ha directly on to the soil.
|Established pasture in spring
|Immediately after grazing apply 100 mL/ha.
|Spring and Autumn, 6–8 weeks prior to required increase in pasture production.
|After grazing apply 2 L/ha in 200 L of water sprayed onto pasture. Co-apply 100 mL/ha BioStart N, N-fixing bacteria for sustained plant growth.
Pasture and Turf Thatch Breakdown Programme
Thatchbusta breaks down the browntop thatch layer which inhibits grass and clover root growth making the pasture drought prone.
Directions for use:
- For best results graze out paddocks and allow sward to freshen prior to application.
- Apply ThatchBusta™ in the early morning, late afternoon or in overcast conditions. Calibrate and clean sprayer before use.

NZ Grass Grub Control Programme
BioShield Grass Grub Liquid is a long-term grass grub control solution that works by introducing a disease that is specific to grass grub larvae, which is then passed from dead grubs to following generations.
|Between February and mid-AprilApply to actively feeding grass grub larvae when they are in the late second to mid-third instar stage of development.
|Dilute BioShield® in 100 L/ha of unchlorinated, clean water prior to application. Apply BioShield® at 1 L/ha via a liquid applicator fitted to a seed drill (e.g. triple disc or direct drill) to a depth of 10–30mm below soil surface, to actively feeding grass grub larvae
Directions for use:
Maximising the activity of BioShield®
- Soil moisture content must be above 15–20% before applying BioShield® on to soil. Irrigate after application if required.
- Apply in 1,000 L of water. Co-apply BioShield® at 4 L/ha to enhance the establishment of BioShield in the soil.
- Do not apply after April as the grass grub larvae will have usually developed beyond the susceptible stages by this date.
Post-treatment management – Do not use:
- Alternative grass grub control practices such as heavy rolling or insecticide treatments after application as this will reduce the effectiveness of BioShield® Grass Grub.
- Cultivation following treatment as it is likely to reduce the effectiveness of BioShield® Grass Grub.
It is an offence to use this product on animals.
BioShield® must not be applied directly on to or into water.
