Coliseum Herbicide (active constituent rimsulfuron) is registered for the control of Wintergrass (Poa annua) & Ryegrass (Lolium spp) in Couch & Hybrid Couch.
Coliseum Herbicide allows turf managers to control the various genotypes of Wintergrass & Ryegrass that other herbicides have struggled to manage, and has shown to be user friendly compared to other herbicides in the sulfonylurea family.
Coliseum Herbicide has very good root uptake and can be washed in just one hour after application, which greatly reduces the chance of tracking and damage to non-target areas. Irrigation should be applied prior to foot traffic the following morning as sulfonylureas can reactivate with heavy dews. The irrigation cycles are short to ensure the product is washed off the leave and to enhance root uptake.
Coliseum Herbicide also has a short soil life of three to seven days, allowing re-seeding seven to ten days after application. This is ideal if overseeding of tees or sports fields is required for assistance with winter wear.
