So glad I invested in this. One 100ml bottle is going to last me years, and it is absolutely magical stuff - pinpoint accurate against all the grassy weeds whilst being perfectly harmless to basically all the turf grass varieties. Pretty much the only one suitable for Qld blue couch, so I'm loving it. It's nailed the paspalum and bahia grass in my lawn in one application, so now my couch can finally get some breathing room.Also, best price I've found in aus. Thanks specialistsales!

We have used this product now for close to a year, over 3 gardens. One garden was well maintained and has given the best results. The 2nd oldest garden has taken 3 treatments and the very old grass has finally given up. Oddly the chickweed has tried and also some patches with clover. The 3rd garden is fairly new, with an old footpath. This one is still under maintenance & the dogs dig up soil and grass, hence the green patches. I love walking around and grabbing old runners and lifting out about a foot worth of dead grass. We did sow some new couch seed with some growth improver as well on the old lawn. Overall we are very impressed with Monument Liquid Turf Herbicide. Some grass will die fast other well established old grass will take time.

Short shelf life
30 October 2024

Works well, but at this price point was hoping the ‘shelf life’ to be at least a couple years. Was sold one manufactured in 2021 and was given an ‘extended’ shelf life letter from sygenta with it, that ends in June 2025. Have been told this is all suppliers have across the country, so buyer beware.

A selective herbicide for the control of Sedges, Grasses and Broadleaf Weeds as per Direction for Use. Active ingredient: Trifloxysulfuron Sodium 10.8% w/w Other ingredients: 89.2% w/w PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT Very highly toxic to aquatic organisms. DO NOT contaminate streams, rivers or waterways with the chemical or used containers. DO NOT apply if rainfall or irrigation is expected to occur within 48 hours. DIRECTIONS FOR USE Situation Weeds Rate Critical Comments Established turf as named: Common Couch (Cynodon dactylon), Durban Grass (Dactyloctenium australe), Hybrid Couch (Cynodon dactylon x Cynodon transvaalensis), Qld Blue Couch (Digitaria didactyla), Zoysia (Zoysia japonica) Burr Medic (Medicargo polymorpha) 115 mL/ha Ensure product placement as uniformly onto leaves and into crowns as possible. Ideal application volume should be 400 to 800 L/ha. Use higher volumes to ensure sufficient coverage in higher cut turf (>15 mm) in semi- roughs, roughs, parks, etc. The addition of a quality non-ionic surfactant at a rate of 0.25 to 0.5% v/v is recommended. A repeat application may be needed in 4 to 6 weeks. Allow at least 6 weeks between last application and overseeding with cool season grasses for winter cover. Transient discolouration may occur when applied to Qld Blue Couch and Zoysia. For Kikuyu suppression, make 2 applications 21 to 28 days apart. Best results are gained from autumn applications. Mullumbimby Couch (Cyperus brevifolius), Nutgrass (Cyperus rotundus) 150 mL/ha Bindii (Soliva sessilis), Winter Grass (Poa annua), 225 mL/ha Catsear (Hypochoeris radicata), Chickweed (Stellaria media), Clover (Trifolium repens) Cotula (Cotula australis), Creeping Oxalis (Oxalis corniculata), Curled Dock (Rumex crispus), Milk Thistle (onchus oleraceus) 300 mL/ha Kikuyu (Pennisetum clandestinum) SUPPRESSION ONLY NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL. GENERAL INSTRUCTIONS MONUMENT LIQUID Turf Herbicide is a selective herbicide for application after emergence of weeds, for control of certain weeds in established turf. MONUMENT LIQUID Turf Herbicide is an oil dispersion formulation that mixes readily with water and is applied as a spray. The degree of control resulting from application of MONUMENT LIQUID Turf Herbicide is primarily dependent upon weed species, weed size at application, environmental conditions, amount of MONUMENT LIQUID Turf Herbicide applied and growing conditions. Weed control is greatly improved when weeds have emerged, ample soil moisture exists and weeds are actively growing, rather than when soil is dry and weeds are under stress from lack of moisture. Growth of susceptible weeds is inhibited soon after application of MONUMENT LIQUID Turf Herbicide. The leaves of susceptible plants normally turn yellow, red or purple after several days, followed by necrosis and death of the growing point. Complete plant death generally occurs 2 to 4 weeks after application, depending on the weed species, growing conditions, etc. Apply to actively growing weeds during early stages of development for best results; For optimum performance avoid mowing for 1 to 2 days prior to and following application.
