This is the broadleaf herbicide Canadian grounds crews, property managers, and municipal turf teams reach for every spring. One litre of concentrate mixes down to treat up to 8,000 sq ft of established lawn, and it hits dandelion, clover, plantain, and thistle without damaging the grass around them. If you're running 40 buildings across Edmonton's core and the first dandelions break on a Tuesday, you want something that mixes fast, sprays clean, and shows knockdown inside 48 hours. That's why this bottle stays in the truck.
Ortho Killex 1L Lawn Weed Control Concentrate 8,000 sq. ft. Coverage: Professional Grade for Canadian Food Service
Ortho Killex is a selective systemic herbicide built on a 2,4-D, Mecoprop-p, and Dicamba blend. That three-way active combination is what makes it work on the tough broadleaf species that shrug off single-active generics. It comes as a liquid concentrate, so you control the mix in your tank, not the factory. Golf course supers, school board grounds teams, and commercial landscaping outfits across Canada run it as a spot-treatment default.
Stocked by ChickenPieces.com at our Calgary distribution hub. We deliver to all 10 provinces and 3 territories, typically in 2-5 business days.
"I'll be straight with you this is the bottle every grounds crew and apartment-block landlord in Western Canada keeps on the shelf. We move pallets of it in spring. One Calgary property manager ran a 1L across 16,000 sq ft of common-area turf in a single afternoon and reordered the same week. Mix it in a backpack sprayer, hit the dandelions in May, move on."
Broadleaf control on commercial turf is more about timing than volume. Spray too early and the weeds haven't pushed enough leaf surface to take up the active. Spray too late and the seed heads have already set. Across most of the country, the window is when dandelions are in full flower and the turf is actively growing, usually mid-May through early June, with a second pass in September once the heat breaks. Killex translocates down to the root after leaf uptake, which is why the top goes yellow within a couple of days but the plant actually dies over one to two weeks. Operators who understand that window burn through far less product than the ones who panic-spray in April.
