"What is the best chemical for creeping Charlie?" and "does Killex kill clover?" are questions people bring to a search engine, and the honest answer to both is on the label. Killex Lawn Weed Control Concentrate is registered with Health Canada's Pest Management Regulatory Agency as PCP No. 27801, and the registered label carries a named list of the weeds it controls. This post reproduces that list and the label's grass cautions so you can check your weed against it before you buy.
Nothing below is our claim. Every quoted sentence is from the registered label; where the label is silent, we say so.
The label's weed list, verbatim
The front panel of the registered label reads: "CONTROLS OVER 50 DIFFERENT LAWN WEEDS". The list that follows, quoted exactly as the label prints it:
"dandelions, fall dandelion (fall hawkbit), plantain, broad-leaved plantain, narrow-leaved plantain, blackseed plantain, chickweed, mouse-ear chickweed, clover, bedstraw, black medick (yellow clover), heal-all, ground ivy (creeping Charlie), knotweed, ragweed, shepherd's-purse, poison ivy, devil's paint brush, buttercup, English daisy, orange hawkweed, mustards, wormseed mustard, prickly lettuce, mallow (young stages), burdock, chicory, dock (curled), lamb's-quarters, kochia, peppergrass, pigweed, purslane, sow thistle, grass leaved stitchwort, blueweed, prostrate pigweed, sandwort (thyme-leaved), pineapple weed, daisy fleabane, birdsfoot trefoil, Canada thistle, smartweed (green), stonecrop (mossy), Russian thistle, bindweed (field), henbit, ox-eye daisy, sheep sorrel, speedwell (purslane leaved), spotted spurge, stitchwort, yellow hawkweed, veronica (thyme-leaved)."
Creeping Charlie, clover and the other weeds people ask about
Ground ivy is on the list under its own name, with "(creeping Charlie)" in brackets beside it. Clover is on the list, and so is black medick, which the label calls "yellow clover". Canada thistle, sow thistle and Russian thistle are all named. Dandelion is named twice: the common dandelion and "fall dandelion (fall hawkbit)". Plantain appears four times, covering the broad-leaved, narrow-leaved and blackseed types.
Two things the list does not say are worth stating. It does not name any grass — quack grass, crabgrass and foxtail are not on it, because Killex is registered as a lawn weed control and every entry on its list is a broadleaf weed. And "mallow (young stages)" is the only entry with a growth-stage qualifier, so on established mallow the label makes no promise.
What the label says about grass
The label carries two grass cautions and nothing else on the subject. "Do not use on bentgrass varieties (golf greens)." And for new lawns: "Do not apply to newly seeded lawns until after 3rd mowing." The label does not list any lawn grass as a target weed. If you are asking "does Killex kill grass", that is the whole of what the registered label says — it names the two situations where you must not use it on turf, and otherwise treats the product as something applied over a lawn.
Where Killex is sold, and the Alberta question
Killex is a Health Canada-registered pesticide, and provinces, territories and municipalities can restrict cosmetic pesticide use. Check your province, city or town before ordering. Pipestone Farm Supply lists all four Killex sizes for pickup in Millet, Alberta (between Leduc and Wetaskiwin, south of Edmonton) and ships Canada-wide (check your province, city or town first): the Concentrate 1 L, the Ready-To-Spray 1 L hose-end bottle, the Ready-To-Use 709 mL trigger bottle and the Ready-To-Use 4 L with wand applicator. The concentrate is designed to be applied with the Scotts Dial 'N Spray hose-end sprayer; the label says "Use with the Scotts® Dial 'N Spray® Hose-End Sprayer or any standard hand-held or backpack sprayer."
Mix rate, rain, mowing and how many applications
We covered the rest of the label — the 24-hour watering rule, the "do not apply when rain is expected" sentence, the 6 mL per litre mix rate, the Dial 'N Spray setting and the two-applications-per-season limit — in Killex before rain: watering, mowing and mix rate, what the label says. If you are choosing between Killex and a glyphosate product, Killex vs Roundup reads both labels side by side. Scotts' iron-based alternative for lawns, Weed B Gon MAX, is listed under weed and moss control.
