Any real weedkillers left in ontario?
I have serious clover and dandelion problem and need a real legal selective herbicide.

Maybe the illegal stuff should be allowed, as along as the user agrees to pay for any cancer treatment their family may need? That way people can have freedom if they want it and don't believe the science?The_Professor wrote: ↑ To answer the OP's question, the "good stuff" (i.e. selective weed killer containing 2-4-D) is banned in Ontario. If you insist on using it however, there are means to get it online through eBay and the like. I believe a seller out west was offering commercial grade concentrated weed killer on eBay and this may still be available. I think it was called PAR 3 or something like that - do a search and I'm sure you'll find it.
Note that you can still get a decent non-selective weed killer in Ontario, but you'd only want to use that on areas where you are okay with everything dying (i.e. not in your lawn).

Looks like the active ingredient is acetic acid. Same thing found in Roundup Advanced.

Well it contains 4.5 grams per litre of 4-chloroindole-3-Acetic Acid ( 4-Cl-IAA ) present as potassium salt, which is different than pure acetic acid.

The science says that 2-4-D doesn't cause cancer according to health canada.

Interesting. The obvious caveat I see is that dandelions don't die after they flower/seed or at least I've never seen it, so how would tricking the plant into thinking it's seeding kill it off? This wilson product might have been the one I saw in store that claimed it killed dandelions after 30 days. By then I'd probably be fed up from having brown dead weeds on my lawn for weeks and just pull them out manually.Shaidin wrote: ↑ Well whatever it is, it smells similar to old weed killers and seems to work. I thought Wilson used some pea derived herbicide.
According to Health Canada, 4-chloroindole-3-acetic acid is a member of the chemical class of chlorinated derivatives of indole-3-acetic acid. It is a naturally occurring plant hormone found in seeds of a variety of annual plants, and then is secreted from developing seeds into parent plants, triggering nutrient mobilization and translocation to seeds, followed by senescence of the parent plant.

2,4-D itself is not carcinogenic but its synthesis produces dioxin (TCDD) as a byproduct which is highly carcinogenic. Depending on the manufacturing process, your 2,4-D could have traces of dioxin.nabiul wrote: ↑ The science says that 2-4-D doesn't cause cancer according to health canada.
