Growth Regulator

Authorisation Number: 
Reg. No. L7170 Act No. 36 of 1947
Pack size: 
1 litre and 5 litres
Composition: 
120.9 g/L
Trinexapac-ethyl
Formulation: 
Micro emulsion

The active ingredient in PRIMO MAXX, trinexapac-ethyl, causes a temporary halt to the production of gibberellic acid, a plant growth hormone which is responsible for the top growth of the plant. Trinexapac-ethyl is taken up by the foliage of the grass plant and is translocated systemically to the growing point of the plant. After application the turf grass grows more slowly than in untreated areas, with shorter leaf blades

A micro emulsion selective plant growth regulator which decreases the foliar growth rate of turfgrasses as specified. Making it one of the most effective products for turf care managers and golf course managers alike saving them huge amounts of time in mower frequency and clipping volume.

Precautionary Statements
  • Avoid inhaling spray mist Avoid contact with eyes, skin and clothing Wash with soap and water after use Destroy empty container. Do not use for any other purpose Do not feed clippings to livestock or allow animals to graze on treated areas
Personal Protective Equipment
  • Wear suitable protective gloves

Other Restriction of Use

PRIMO MAXX will not slow the growth of weeds in the turfgrass
Do not use application procedures and equipment which will leave untreated strips or large overlaps in the treated area.
There should be ample foliage for spray contact
PRIMO MAXX does not inhibit the formation of grass seedheads.
Apply PRIMO MAXX to actively growing turfgrass.
Avoid applying PRIMO MAXX to turfgrass which is stressed from drought, disease, frost, low fertility, insect or mechanical damage.
In some instances where the turfgrass is not adequately fertilized or is under drought stress, some discolorations may occur. Such discolouration is temporary and will disappear when stress conditions are eliminated.
The turfgrass should not be mowed within 12 hours after the application to allow PRIMO MAXX sufficient time to translocate to the growing point.
The application of nitrogen fertilizers may result in less growth retardation of PRIMO MAXX since the turfgrass will respond to the nitrogen.
