Stinger herbicide for thistle control

question came up on organic farming topic, this stuff works pretty well, not affordable
Stinger herbicide

In pastures and CRP Milestone, Forefront, or Grazon+P are the most used products up here.

cousin used this on set aside ground 15 years ago for thistle control, not schooled up on current products, it was terribly expensive at the time but it does kill thistles

I forget now, but the active ingredient of Stinger is in another product or 2, and cheaper in the other product.

Just wondering why Stinger came up on an organic farming topic - surely cant be considered for organic approved?

It does work well on thistle, clover and other broad leafs, follow the label - as they say your mileage may vary.

Incidentally the product is called Lontrol in Canada. It costs 2 what you pay in the states :>(

Stinger is deadly on Canadian thistles. I've spot sprayed stinger on tough patches in corn in early June and one spray wiped them out. I use Grazon on thistles in CRP but it usually takes two shots to get the job done. Maybe my timing has been off. In CRP you only have a certain window to spray when THEY think it's OK unless you do it under the radar. Jim

Thinking Curtail is one. I am sure there are others.

Thanks Todd,
I've got Canadian Thistles trying to take over some pasture and hay ground. I spot sprayed with Crossbow and killed lots of them, I guess last fall. When spring gets here then I will see how many come back. I'm going to see if I can find some Stinger and give that a try. I hate thistles and want to rid my pastures of them. Since both pastures have very little clover, I'm wondering if I can spray it all with a boom sprayer and not kill the grass? I'll go to their website and see what they have to say. Sometimes it's easier to talk with someone who's used it in the past, rather than to try to read all the stuff on their website.
Thanks again Todd,
Dick

Stinger and Lontrel are the same thing with different labels intended for different markets - Lontrel is mostly for the landscapers where Stinger is marketed for ag use. Other brands exist with different amounts of concentration.
It doesn't take much active ingredient in the tank mix to work.

There are several products with the same active ingredient: clopyralid.
Here is a sheet on roadside weed control:

This is a list of various herbicides that contain clopyralid and the percentages:

I used a mix of Lontrel and 2,4D on and area that had a lot of thistle and other nuisance weeds and it did a good job. You never get it all on the first try, but another application maybe a year later should get most of the stragglers. Keeping it mowed thereafter so it can't build nutrients in the roots or go to seed pretty much wipes it out over time, although I wouldn't be surprised to see some try to come back from old dormant roots.

PS. - Forgot to mention that you need to check to see if the herbicides are recommended for grazing or crop land or what the waiting period is for them.
