Coliseum 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 has very good root uptake and can be washed in 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 leaf and to enhance root uptake.

Coliseum has a short soil life of 3 - 7 days, allowing re-seeding 10 days after application. This is ideal if over-seeding of tees or sports fields is required for assistance with winter wear.

Available in 100g and 1kg.

Mode of action

Coliseum is an ALS inhibitor, it disrupts the biosynthesis of the essential amino acids, valine and isoleucine.
