Coliseum Herbicide – Post-Emergent Control for Winter Grass & Ryegrass in Couch Lawns
Coliseum Herbicide is a powerful post-emergent herbicide designed to control Winter Grass (Poa annua) and Ryegrass (Lolium spp.) in Common Couch and Hybrid Couch lawns. It targets tough genotypes that other herbicides often miss and is easier to use than many sulfonylurea alternatives.
With strong root uptake, Coliseum can be watered in just one hour after application, reducing the risk of tracking and damage to non-target areas. It also has a short soil life, allowing for overseeding just 7–10 days later—ideal for lawns needing winter wear recovery.
