Primo MAXX® £0.00
Primo MAXX®
Primo MAXX® works by blocking the production
of gibberellic acid late in the cycle – which
effectively limits cell elongation. The result is to
shorten the distance between the shoot nodes,
leading to more compact growth.
whilst the vertical growth is slowed, both
root and lateral growth are boosted creating
stronger, healthier and denser surface.
First application and timing:
Primo MAXX applications can start as soon
as consistent grass growth commences. This
normally occurs between mid April to mid
May onwards. However, sometimes some
parts of the country may not get consistent
grass growth until later in the year.
Consistent growth normally occurs when air
and soil temperatures are consistently 8°C
– 10°C or above for an extended period of
time (e.g. more than five consecutive days).
Nutrient input and tank mixing:
Consistent healthy turf growth normally
requires nutritional input. Most turf managers
who have used Primo MAXX have also tank
mixed appropriate liquid fertilizer as this
eliminates the need for separate applications
and can enhance the overall effect of each
Primo MAXX application.
Primo MAXX is physically compatible with
liquid fertilizers and nutrients. For other tank
Mixes, including herbicides and fungicides,
consult your technical advisor before application.
The new liquid formulation Primo MAXX is
easier to handle and measure than powder
formulations. It rapidly and evenly disperses
In the tank for easier and more effective
spraying rates and thus improves the timeliness
of applications.
Application advice:
Apply Primo MAXX in a water volume of
300 to 600L/Ha in a medium quality spray.
Lower water volumes will increase work
rates and thus improve the timeliness
of applications.
Shaded areas:
Grass plants growing in shaded areas create
more gibberellic acid in an attempt to reach
The light – resulting in tall, etiolated growth.
The application of Primo MAXX to suppress
gibberellic acid production will help to
minimize these effects and create a denser
healthier surface.
The MAXX formulation:
Advantage:
The MAXX formulation has been specifically
Designed for turf. It is:
• Very safe to turf
• Increased and enhanced product
Uptake
• Very stable in the tank
• An easy to use liquid formulation
• Has fl exile application rates for all
Turf surfaces
• Compatible and easily mixable with
Other products
Grass species:
Primo MAXX is specific to turf management
and has beneficial effects on all grass species
typically sown on
rates for fast growing perennial ryegrass are
higher than fine Bent, Fescue and Poa species.
Number 1 innovation in greenkeeping:
FIRST APPLICATION: Mid April – Mid May

Fairways
FIRST APPLICATION: Mid April – Mid May
APPLICATION FREQUENCY: Every four to five weeks.
HEIGHT OF CUT: 10mm –18mm
DOSE RATE: 0.8 – 1.6 l/ha for fine turf fairways, up to 2.4 l/ha for
Predominantly Perennial Ryegrass turf.
ADDITIONAL INFORMATION: Rate is dependent on height of cut. Tank
Mix an appropriate liquid fertilizer to enhance the overall effect.
APPLICATION PROGRAMME:
The Primo MAXX programme can be commenced at any stage of
The growing season, but ideally should start at the onset of spring
growth and continue whilst grass is actively growing.
Primo MAXX programmes will give the best results in preventing
the effects of drought – by maintaining healthy grass for longer and
aiding rapid recovery – if a series of treatments are made before
grass comes under stress (Pre-Stress Conditioning).
If grass growth stops during extended dry periods, Primo MAXX
application periods may be extended until moisture and growth
returns.
Do not apply Primo MAXX to stressed turf.
GRASS CUTTING:
Primo MAXX will slow vertical grass growth within one to two
weeks of initial application. Continue to mow greens as normal.
On other areas of the course mowing intervals can be extended
as the cumulative benefits of the Primo MAXX programme take
full effect.
The first noticeable difference will be far fewer clippings to
remove – up to 50% less over the season. This will significantly
Increase mowing speed and reduce wear and tear on equipment.
It will also reduce any financial burden under new composting
waste legislation that may apply to golf courses.
As Primo MAXX encourages lateral growth, to create denser
ground coverage, the slower vertical grass growth will provide
greater fl exibility in cutting intervals and mitigate the effects
of rain disrupting the cutting schedule.
Slower vertical grass growth will retain visually appealing
cutting patterns for longer.
Cut height vs. Application timing:
Where course policy is for grass to be cut at a lower height,
Primo MAXX applications should be more frequent, but at a
lower application rate. Overall season-long application will
remain broadly the same.
Primo MAXX was voted the Number 1
advancement in modern greenkeeping, in
a survey for Golf week’s Super NEWS. It was
cited as the first PGR that could be safely
and predictably used on all fine turf areas,
which has proven an invaluable tool to save
mowing labor and maximize turf colour
and density.
