For Post-Emergent Control of Winter grass (Poa annua) and Ryegrass (Lolium spp.) in Common Couch and Hybrid Couch Turf 

Coliseum Herbicide is a post-emergent herbicide registered for the control of Winter Grass (Poa annua) & Ryegrass (Lolium spp) in Couch & Hybrid Couch.

Coliseum Herbicide allows control the various genotypes of Winter Grass & 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. 

Coliseum Herbicide also has a short soil life, allowing re-seeding seven to ten days after application. This is ideal if overseeding of your turf area is required for assistance with winter wear.

Features and Benefits

  • Outstanding post emergent control of Winter Grass & Ryegrass
  • Excellent Turf Tolerance on Common & Hybrid Couches
  • Flexibility to over-sow 10 days after an application
  • Does not delay couch spring green-up when applied during dormancy
  • Does not reduce cell elongation & growth
  • Control of Winter Grass & Ryegrass on newly planted couch as early as 5 weeks after planting or seeding, with no phototoxicity or long-term retardation of growth  (Note: root depth of the couch at the 5 week stage was measured at 5 cm at the time of application as per label instructions)

Application should be when weeds are healthy and active (Autumn and Spring) prior to cool weather. Inferior weed control results may be observed during cool weather (Winter).

Apply to weeds that are healthy and actively growing, Coliseum works best when daily air temperatures are a reaching 18ºC. Warmer temperatures lead to best results, i.e. when daily air temperatures are reaching 21ºC and higher.
If air temperatures are only reaching 15ºC or lower, sub-par weed control may be observed.
It is not advisable to use Coliseum Herbicide during cold periods in winter (i.e. daily air temperatures only reaching 15ºC or lower).

        A true turtleneck that retains a snug high neck.
        Color: White, Size: X-Large
        I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
