Trinexapac-ethyl is the active ingredient
in ‘Primo MAXX’ that works by
redirecting plant growth. It specifically
targets the gibberellic acid site
responsible for cell elongation in grass.
Not only does ‘Primo MAXX’ inhibit
vertical growth but actually diverts plant
growth downward into the root system to
produce increased food reserves and
lateral stem development. This in turn
produces a thicker, healthier sward that
better equips your turf to withstand
temperature extremes, moisture loss,
traffic and wear and even helps in the
management of Poa annua.
‘Primo MAXX’ can be used on all well
maintained quality turf grass areas. It can
also be used to help manage areas which

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).
GREENS APPLICATION PROGRAMME
First application: Mid April
Application frequency: Every 3 to 4 weeks.
Height of cut: 7mm or less.
Dose rate: Apply at a rate of 0.4 litres/hectare throughout the season.
Additional information: Extend seasons if growth starts early or finishes late.
TEES APPLICATION PROGRAMME
First application: Mid April
Application frequency: Every 4 to 8 weeks.
Height of cut: 10-18mm.
Dose rate: 0.8 litres/hectare for 10 mm cut; up to 1.6 litres/hectare for 18mm cut
height.
Additional information: If tees are of dwarf perennial ryegrass consider increasing
the frequency of application.
FAIRWAYS & AMENITY APPLICATION PROGRAMME
First application: Mid April
Application frequency: Every 4 to 8 weeks.
Height of cut: Less than 18mm.
Dose rate: 1.6 litres/hectare for fine turf fairways, up to 2.4 litres/hectare for
predominantly perennial ryegrass turf.
Additional information: For fairways cut at lower heights (approx. 12mm or less)
make more frequent applications, but reduce rates.

tolerance and

Primo MAXX was voted the No. 1
NUMBER advancement in modern
greenkeeping, in a survey for
Golfweek’s SuperNEWS. 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 labour and
maximise turf colour and density
ROUGH & SEMI-ROUGH APPLICATION PROGRAMME
First application: Mid April
Application frequency: Every 5 to 8 weeks.
Height of cut: More than 18mm.
Dose rate: 2.4 litres/hectare for fine turf mixtures, up to 3.2 litres/hectare for
predominantly perennial ryegrass turf.
WINTER SPORTS PITCHES
First application: Mid April
Application frequency: Every 4 to 6 weeks.
Height of cut: 10mm and above.
Dose rate: 0.8 litres/hectare for the first application. Following this, use 0.8
litres/hectare for turf cut below 18mm, 1.6 litres/hectare for turf cut higher than
18mm. In certain situations (very vigorous growth, high maintenance inputs) it
may be appropriate to increase the rate up to the maximum label rate of
3.2 litres/hectare.
