Spray to kill thistles

[dun]

Does not have berries. Covered with millions of hair like stingers on the stalks and underside of leaves. If you touch it it will burn, itch, and leaves blisters and rash. Grows 1' to 2' tall, has a tap root anywhere from 6' to 10' deep. has a root ball at the end of taproot that looks like a sweet potato on steroids. We've dug one up that the root ball was 27" long and 7 1/2" in diameter 9 feet below ground level. They put on a white flower in mid summer. I'll try and find an early sprout to post a picture of.

What does to seed container that replaces the flower look like?

Horse nettle

That was always my interpretation too until I moved here. Here the one I alwasy called horsenettle is what they call bull nettle. If you mention horse nettle you get that deer in the headlights look.

2,4-D is cheap, so you get what you pay for. Though it it a great product, I wouldn't waste my time! I would strongly recommend Milestone and if not then Grazon. You will get residual contral that lasts! I'd spot spray in the spring then broadcast it in the fall. You will have unbeleivible results! Stay on top of it for a couple of years and make sure your neighbors do too! Before long you'll forget what a thistle looks like! LOL If you have any woody stemd plants that you are wanting gone also. I'd recommend using the Grazon. If not Milestone is the only way to go

When I worked for Riverbend in Idaho we used Curtail and it seemed to get a very good kill. Here is what it says on Dow's website about it:

Exceptional season long control of Canada thistle and perennial sow thistle and effective results on a wide range of broadleaf weeds in wheat, barley and oats is provided by Curtail M. It contains a Group 4 mode of action and can be tank mixed with many different grass weed herbicides.

Wow ! Man if thats the truth I would use a chisel plough set at 3 to 6 inches with bat wings (side cutting blades) set on it to slice it off below ground level so it dies and the tap root breaks down in the soil and this will tend to deepen and enrich your topsoil over time.

Find one in the clear where no others have seeded the ground before so old seeds don't come up and contaminate your result. Make sure it is not near to seeding either or you will disperse the seeds with your action.

Mark the position of it so you can find it from time to time Take a shovel and chop it off 3 inches below ground level then throw the earth back over it and see if it comes back up. I doubt it cause the microbes in the soil will enter the cut stalk and start breaking it down pretty quick.

If you see any regrowth check down to see if the stalk is active or if it is a stray or new seed sprouting

This will take probably 12 months and you can try any treatent you decide on but just leave this one site alone and keep checking back. Then if your program does not work you can change to one that does later

I guess that's why they call it a bull nettle :lol: The only control that seems to work is persistence and a hoe. Thank God for my wife.

tytower you must not have weeds that have rhizomes as a new growing point. If you are hand chopping thistles and killing them they must blooming as that is the only time it will work (maybe).

Middle Tn. folks also call the purple flowering, yellow berry, plant, bull nettle. I have since boyhood and that has been a while. ;-)

We have many growing from rhizomes such as Bracken and Sensitive Weed
Most poisons (I spray these by backpack with a double strength mix) don't kill these including Grazon Starane and Esteem . They kill the growth but not the rhizome and I have dug up the rhizomes
(roots) and seen new shoots within three months of spraying . A dead stem on one end from the poison (Grazon) and a new green stem on the other end.

I think it is a matter of interpretation of the word thistle.

In Australia what we call nettles and thistles look like the first picture posted in this forum and I will try to photograph one myself and post it here.

This is one but not the main one I'm thinking of

The third picture posted before in this forum is what we call a wild tomato or thorny tomato if the seed pods are the same inside ,tomato-ish

I am out in the paddock often. If you don't have much, get a hoe and just chop em off about ground level. Easy as pie to do . I use an old adze ( old timber cutters tool) and nice and sharp and don't hit the ground . Watch the follow through though for it hurts if you bury it in a shin.

If you cut them, be sure to burn the flowers so they don't go to seed.

I've looked at your photos. We hit them before they flower if we can with a mattock. We cut the root below the ground. One cut one kill most of the time. We don't have much of a problem with them anymore but you have to stay on top of it.

We keep a mattock in the truck but don't have to use it as much as we use too.
