MONUMENT LIQUID Turf Herbicide (trifloxysulfuron-sodium) is the best sedge, broadleaf and grass control partner in Couch with reliable and effective results. This proven herbicide remains a powerful first choice for many turf managers to manage sedges and broadleaf weeds. The active ingredient in MONUMENT – trifloxysulfuron-sodium – is viewed as one of the most powerful and reliable sedge control options in turf. 

Achieve top results with MONUMENT – the leading weed control solution. With 9 years of use in couch turf in Australia, you know you can trust MONUMENT to control the widest range of tough weeds like Winter Grass, Ryegrass, Nutgrass and many broadleaf weeds including Clover and Burr Medic. 

Used correctly, this will be the only Sulfonyl-urea herbicide you need. MONUMENT delivers excellent, reliable results when keeping a few important points in mind.

What MONUMENT LIQUID offers you:

  • Highly effective control of Winter Grass, Ryegrass, Kikuyu, sedges and a wide range of broadleaf weeds.
  • A convenient liquid formulation with low environmental loading.
  • Excellent resistance management strategy when used in combination with BARRICADE® Turf Herbicide.
  • Fully systemic action with root, shoot and leaf uptake.
  • Effective management of Bahia Seedheads.

MONUMENT is the established sedge and broadleaf destroyer - a powerful solution for controlling sedges in turf.

  • Excellent turf grass safety over a wide range species
  • Kills sedges and broadleaf weeds at growth points; roots tubers, vegetative plantlets and stem growth points.
  • Inhibits growth leading to cholorsis, sedge and other weed’s death.
  • Actively up-taken by foliage above ground and roots below ground
  • Complete systemic action traveling by both xylem and phloem to growth points

The active ingredient in MONUMENT inhibits Acetolactate synthase (ALS inhibitor), efficiently rendering the weed incapable of producing amino acids, which are the building blocks of cells. The weed is then incapable of continued growth and function, leading to weed death.

MONUMENT is readily taken up by leaves, shoots, crowns, stolons and roots of sedges and other weeds. This herbicide starts as a foliar absorbed product, and the subsequent irrigation required for turf health places MONUMENT into the soil profile. Here it continues to be effectively taken up by the weed’s roots, ensuring maximum effect. Complete weed treatment is achieved through the flexibility of uptake, partnered with the strong redistribution in weeds which makes MONUMENT a powerful option for established sedge populations. 

Top Tips

  1. Consider weed growth stage at time of application - Annual weeds such as Winter Grass and Ryegrass do become “green skeletons” during certain times of the season. For example, Ryegrass in early October may still survive due to irrigation and fertility levels required for surface appearance, but these plants are no longer growing actively and with no sap flow there is no capacity to transport MONUMENT systemically. This might lead to sub-lethal rates of uptake and less than optimal control.
  2. Consider the soil temperature at time of application - SU herbicides are soil temperature sensitive and application in the middle of winter with soil temperatures below 12ºC may result in very little uptake by weeds and thus less than optimal control. 
  3. Always apply with a non-ionic surfactant - A good quality surfactant that does not influence the pH in the spray tank and increase coverage of the target weed is the way to go. Refer to the MONUMENT label for full details.

Making sure these tips are carefully considered will ensure the best possible chance for top level weed control.

MONUMENT® LIQUID can be used as a post-emergent herbicide on the following warm season turf species: Common Couch, Durban Grass, Hybrid Couch, Queensland Blue Couch and Zoysia.
