    Description

    Coliseum Herbicide 25g

    Coliseum Herbicide 25g is a highly effective selective herbicide for post-emergent control, specifically made to tackle Wintergrass (Poa annua) and Ryegrass (Lolium spp.) in Common and Hybrid Couch turf. Its active ingredient, Rimsulfuron, works by inhibiting essential amino acid production, providing excellent control over these weeds. Coliseum is particularly user-friendly compared to other sulfonylurea herbicides, making it a preferred choice for turf managers.

    Key Features

    • Selective Post-Emergent Control: Effectively targets Wintergrass and Ryegrass without harming Couch turf, ensuring excellent turf tolerance.

    • Low Application Rates: Coliseum Herbicide 25g requires only 75-100g/ha for Wintergrass and 120g/ha for Ryegrass, reducing environmental impact.

    • Short Soil Life: Allows for re-seeding just 10 days after application, ideal for maintaining healthy turf during winter.

    • Systemic Action: Works through root and shoot uptake, ensuring thorough weed control.

    FAQ

    Can this Selective Herbicide for Post Emergent Control be used on newly planted turf?

    Yes, Coliseum Herbicide 25g can be safely applied to newly planted Couch turf as early as five weeks after planting or seeding. At this stage, the root depth of the turf should be at least 5 cm, as per label instructions. It provides effective weed control without causing phototoxicity or long-term growth retardation.

    How does Coliseum Herbicide 25g minimise damage to non-target areas?

    This Selective Herbicide for Post Emergent Control has excellent root uptake and can be watered in just one hour after application, reducing the risk of tracking or offsite movement. This ensures that the herbicide remains effective in the target area while minimising potential damage to surrounding plants. Proper irrigation cycles further enhance its precision and safety.

    Is it safe to re-seed after using Coliseum Herbicide 25g?

    Yes, Selective Herbicide for Post Emergent Control has a short soil life of three to seven days, allowing re-seeding within seven to ten days after application. This makes it ideal for overseeding tees or sports fields that require quick recovery and winter wear assistance. Always follow label recommendations for best results.

    Coliseum Herbicide 25g is your trusted solution for effective post-emergent weed control in Couch turf, offering superior performance with minimal environmental impact! See our Selective Herbicide range.
