I have a bit of a quandary. Canada Thistle, wild blackberry and another type of low growing viney w/small thorns pain in my butt are trying to take over areas on a property that I hunt.
Canada Thistle is in a large grassy field. I spot sprayed over 500 (I'm guessing) last year and killed them before they blossomed, but it seems that just as many popped up this year. It took 2 full days last year to spot spray them.
Same field, has a lot of blackberry starting to grow.
I burned the field this Spring, but in places it didn't get hot enough to kill the blackberry.
Is there anything I can broadcast spray to kill the Thistle and the Blackberries but not whack the rest of the field? I have a 60 gal 3-point sprayer with a 12' boom.
I've got that same blackberry or wild raspberry growing along the edges of the trails going thru the woods, and it's starting to overhang at least 1/3 of the width of the trail in many places. We're talking over a mile of walking paths that it's trying to overtake.
Is there anything I can use to spray that but won't kill native tree saplings?
Then there's the Greenbriar that I know I'll have to spot spray.........

The best chemical I use to treat broadleave trouble makers is crossbow/crossroad. I get it at my local rural king store. Now....it will kill small saplings and the like as well. The only other means I have seen to control the plants you describe is with mowing. If your worried about killing too much, consider a wiper type application method as well.
Best time to kill thistle is in the spring....early. Once it get to flowering and the like it's a mature plant and you may kill what you see, but thistle has an extensive root system and will produce new shoots from it unless you kill the entire plant. I have a grassy area as well....I mow 2 or 3 times a year and then try to spray in the spring once I just start to see the thistle popping up.
I try to leave any berry plants and green briar be as they have wildlife value. To trim along trails we once used gas powered hedge trimmers to push them back. It obviously takes time, but it beats trying to do it by hand. They also make blade for straight shaft weedwackers to cut that sort of stuff as well.

I'm in the process of mowing the thistles now, (7-8 acres). No flowers yet and some are over 6' tall. I have the brush hog set at about 10" height. If they pop up again I can now go around with glyphosate and hit the new growth. The other stuff that was growing was tall enough to make going around spraying difficult. There's plenty of berry and green briar on the place, it just needs to stay out of the field and off of the walking trails. I didn't get a hot enough fire this Spring so not all of it died. About 50% did though! |

Just an update:
One month post mowing they haven't popped up (yet) and I see no flowers forming (again "yet"). I did a spray of the trail edges with Crossbow and the Greenbriar was unfazed. Sassafras seemed to be the most susceptible to that, along with the Rasberries/Blackberries.

I’ve found that they will come back in the spring even after mowing I’ve also seen were I’ve sprayed them due to bare ground new ones pop back up two feet away as said they are hard to kill.
I mix a bit of 24D and round up together when I spray them .
On small trees thorn trees and the likes I use a product called pathway it’s a bit of work as you spray at the base of the tree I believe it’s called Basiling or something like that.
What I like about it is it’s sprayed in the fall up to February at least around here as long as the tree is sucking back down into the roots it works once the sap moves upward it’s not near as effective
The other thing I like is it doesn’t cross over to other roots that maybe intertwined with the tree bush your trying to kill

Canadian Thistle is tough. Had a lot of it in my prairie grasses when first planted, spot sprayed it but it was tough and some came back. Luckily the prairie grass has eventually choked most of it out. I've been told by an old timer that there is a certain time of year and moon phase if you mow it then it won't come back?
