Monument Herbicide 100mL is a professional-grade selective turf herbicide used to control winter grass, ryegrass, nutgrass, sedges, kikuyu suppression and a wide range of broadleaf weeds in established warm-season lawns such as couch and zoysia.

Is Monument Herbicide safe for Buffalo and Kikuyu lawns?

No, Monument Herbicide is not recommended for buffalo lawns or kikuyu lawns as damage can occur. It is primarily designed for use on couch, hybrid couch, zoysia and other suitable warm-season turf varieties.

How do you mix Monument Herbicide 100mL?

The typical application rate is approximately 1.15–3mL per 100 square metres mixed with water and applied with a quality sprayer. A non-ionic surfactant such as Wetter 600 is commonly recommended to improve weed coverage and uptake.

Can Monument Herbicide be used with a surfactant?

Why is Monument Herbicide popular for couch lawns?

Many turf managers and lawn enthusiasts use Monument because it offers broad-spectrum selective weed control for couch lawns, targeting sedges, grassy weeds and broadleaf weeds without damaging healthy couch turf when used correctly.

Can Monument Herbicide control winter grass?

Yes, Monument is widely regarded as one of the most effective post-emergent herbicides for controlling winter grass (Poa annua) in couch lawns and sports turf. Lawn care communities frequently recommend pairing it with a pre-emergent herbicide like Barricade or Spartan for long-term control.
