Best way to kill tumbleweed?


Recommended Posts

Anybody know a good way to get rid of tumbleweed? It grows everywhere here and is a major pain. I try to pull it out by the roots and have had a little success with putting down the ground clear chemical stuff, but even that doesn't seem to do a good job. I'm all ears :huh:

Get some Roundup or other glyphosate or sulfosate concentrate, as well as some 2,4-D (Weed-B-Gone contains this, along with other compounds in the same class of chemistry). Mix these according to label directions and then add a tablespoon or two of dish soap. The dish soap acts as a surfactant, helping the solution spread and stick to the vegetation. The Roundup and 2,4-D are synergistic, an old standard in the no-till farming industry.

The trick with any herbicide application is to get the plant before it germinates or when the plant is actively growing. Herbicides generally affect some biological process - growth regulation, photosynthesis, amino acid synthesis, pigment inhibition, etc. The 2,4-D is a synthetic auxin, which basically tricks the plant into growing itself to death. The Roundup, is an amino acid inhibitor, which affects plant growth. Basically, the 2,4-D will help Roundup get deeper into the plant's system - a one-two punch.

Another thing you might try is to look for something that has the active ingredient diquat dibromide. You should also be able to mix this with 2,4-D. Just make sure that your water is clean.

tumbleweeds are the way the acutal plant, russian thistle, spreads its seeds. Big Dave has the right mix. You MUST get the thistle before it germinates. If you don't, then better luck next year.

the fall spraying will help keep the seeds of next season from growing in the spring, but its the spring spray that is crutial.

If they stack up, it helps to burn them, but don't openly transport them too much, they spread their seeds very easily. The more they move the more they spread.

Interestingly enough, russian thistle thrives in drought conditions. Wet years have a tendency to suppress their spread. pray for good fall rains.

And here us Florida boys thought tumbleweeds were the big clumps of brush we saw rolling along the ground in the old western movies.

You learn smoething on BE everyday.

They are, Russian Thistle is the proper name.
