I wonder if it isn't something you could knock out with lime, sulfur, or drainage? I did some googling and couldn't find anything yet.

Not sure. We burned it and hit it with gly so far. That is about all we have tried.

Holy shit that would keep you busy.
Tests involving large-bore needle injection of glyphosate into the lower nodes of each stem have been successful.
Good luck

Good luck I have been having fair luck on Canadian thistle with 50% solution of roundup. Injection of plants in my yard might be an option. I have also sued the shovel trick that Stu mentions.

I've been knocking Canadian thistle back with about the same solution of gly as you. The shovel trick won't work on Canadian thistle. It grows via a massive underground root (stolon?) system, so if you cut one shoot off the mother plant simply sends more shoots to the surface. The same thing happens when using herbicides on C.T. My understanding is that a guy has to continue to knock back the top growth continually, by doing that you'll eventually kill the underground roots due to lack of food from no photosynthesis.

Can you leave a strong mixture of roundup in a 2 gallon sprayer? Will it stay potent?......or damage the sprayer?? Seems I never have a mixed batch of gly available when I need to get after a new thistle outbreak. Lots of them now.

Seems I never have a mixed batch of gly available when I need to get after a new thistle outbreak. Lots of them now. Probably not good to leave any herbicide in a sprayer. That said, I've done it for a few days with no noticeable impact to the sprayer or the effectiveness of the herbicide. One thing to be aware of is that glyphosate will do a poor job at controlling thistles once they bolt, and once they begin flowering it will be even less effective. Gly does a good job on killing thistle rosettes, and young tender growth. Other than that, a guy should be using something else IMHO. I've got to mix up a sprayer full of Milestone next week and hit some thistles that will be blooming soon.

Is milestone available at Fleet??? I should have bought some from MO.
I seem to have allot of thistles this year. Not sure when I can get at 'em. Got a wedding today and tomorrow......and some golf to play in Mpls......maybe another week I can attack 'em.

Got a wedding today and tomorrow......and some golf to play in Mpls......maybe another week I can attack 'em. I don't think so, no. I bought mine from MO. I've had a near explosion of Canadian thistle this year. Not sure what the deal is, but I've spent many, many hours spraying them already.

Just ordered a quart of Milestone from Keystone. Way more canadian thistles this year......and I intend to get after them this season. Also bought a 1 gallon sprayer so I can carry it on my tractor when mowing or doing other work. Seems I always see some thistle.....and don't have a sprayer handy to get after 'em. Maybe this will help.
Thanks for the tip on Milestone Stu.....kinda expensive but great reviews on killing thistle for keeps.
