Weed killer
 

I've tried two different weed killers from Tractor Supply. They work temporarily but In the Spring the grass and weeds come back even better than before! :bash2:
I want to kill it. Is this an EPA thing or something like that? Have any of you found anything that works? :Huh:

I would get one that's called "ground clear" as long as you want NOTHING to grow where your using it. For walks and patios I use a propane torch.

I've never done it myself, but some folks use rock salt in areas they want to prevent growth, like gravel driveways and walks.

I think you need to understand a bit more about what you are doing, and what you want.
Most all herbicides are only contact killers. You have to get it on the plant, and the plant dies. Some herbicides don't kill to the root, so more sprouts come from the root. Some do kill to the roots. Not many herbicides have residual control. Not ones you can buy anyway. But they are out there.

Someone mentioned rock salt. Yes, that will work, but it turns the soil highly acidic and it won't grow anything ever again. It basically ruins the soil. On a driveway I suppose it will work, but be careful. The salt will spread when it rains. If water runs off the area into grass you want.....

I'm basically doing my gravel driveway and a few spots out in the yard. When I went to TSC, I asked them what they would recommend. At first it was Amine 400 2,4-D I believe. The next summer it grew back so I went back and was told to try Barrier. I don't recall what it's makeup is but it does say for "up to one year" (duh).
I sprayed it with Amine 400 again last summer because I ran out of Barrier and this is what I have again. I originally told them I wanted to get rid of the weeds, they have been no help yet.

2,4-D is only a broadleaf killer. It doesn't kill grass, or anything in the grass family. You need a glyphosate. (Round-up).

Well, TSC is probably just trying to push their products. I passed up Round-up at other stores thinking a tractor place would have better stuff. :bash2:
Thanks Jonathan.

Crazy
 

I just looked up Round-up. It's only good for up to 12 months as well. I guess I have no choice. :Unknown:

TSC carries Round-Up by name brand, and in their house brand.

Randy, nothing lasts longer than 12 months. Even the most expensive herbicides have to be applied every year.

On another note, grading a driveway regularly also helps control weeds.

Salt might be a good thing for a driveway... Salt it good and put down some RCA! Got a box scraper for your tractor?

As I mentioned earlier, salt might be ok if water doesn't flush the salt into the yard. After a few rains, he might be upset..... I wouldn't do it.

I'd Round-Up it, and grade it often.

X2 on the 2 4 D. It doesn't kill half of what I see on your driveway, only broadleaf. And J-Mech is right on the glyphosate as well. This is what you need to kill everything, and like he said, nothing that you can get over the counter is going to last you 12 months. For a cheaper and less toxic solution, you can mix some clorox in water and spray it on them. It will kill everything it touches as well so long as you don't dilute it too thin. This won't last as long as round up though.

If you are spraying this stuff, don't do it without a respirator. This stuff is a bad carcinogenic.

I don't know where the myth is that Roundup lasts for months. Maybe in retail stores there is a mix of Roundup and something else, one for a burndown and the other for "season long" control. All I know Is I use real Roundup (power max I believe) and I have to come back 2-3 times over the summer to keep weeds and grass at bay. In fields, a crop generally takes over and provides so much competition that a new crop of weeds can't survive. The 2-4-D products I use on fallow land don't have any carryover that I have observed either. I try to alternate away from glyphospate when I can so as not to contribute to herbicide resistance.

Respirator when applying bleach?
What about the millions that use it everyday in the laundry?
None wear respirators.
If people are stupid enough to stand down wind while spraying it, well it just shows Darwinism is real.

glyphosate has to be absorbed by the plant via foliage.
It will kill the plant and the roots so it won't come back.
But seeds might be dormant in the ground for years before they sprout.
Maybe after annual treatment with glypho for several years the amount of sprouts will be less and less.
But birds and wind are always adding more seeds.

No sir. Glyphosate.

Surely you know it has a high toxicity. I apologize if my post was confusing.

No, I don't want to use salt. I get this with heavy rain!

Tractor Supply sells this, and it will keep everything dead for 2-3 years,,,

At one time we had nothing that could kill Johnson grass,,
We tried Pramitol, it did kill the Johnson grass, but, in 3 years, the first plant that would grow in that spot was,,,,, Johnson grass,,, :bigthink:

:bigeyes:

Johnson grass is next to impossible to kill. BTDT. WE don't have much of it here.

Pramitol is only a single season killer. It does have residual, but if you kill what is there at the root, it would likely appear to work for a few seasons. It's made to kill at the root, and is a bare ground herbicide. However, it too can spread, and with the flooding that drive takes, I still wouldn't use it. It can spread. I'm surprised TSC carries that. I thought you had to have an applicators license to buy it. It must not be full strength.

Well. If it helps, heres the torch I use on all my patios and my brick walkway. I just burn em all then sweep or blow them away. I only have to do it once per year and its instant gratification. No waiting for chemicals to soak in.

Roundup causes the plant to be unable to uptake water, so it dies of drought.
I spray my driveway 2x a year. I guarantee the grass/weeds it has killed, do not regrow.
What grows, is new seed that is there.
2 qt. in 20 gal will exterminate anything growing, but if a seed germinates the next day, roundup will not stop it.
Spray while the plant is actively growing and @ least 24 hours before a rain.
Do not spray when it is Hot-- *90 --- or cold *40, as the weed will be slow to uptake the Glyphosate.
Occasionally you might encounter a weed that has mutated, and will be roundup resistant, but that is not the norm.
If you have weeds that are waxy like button weed, a Non-Ionic Surfactant added will allow the Glyphosate to translocate into the weed better.

It surely will. That's much stronger than what I usually mix up. I've gone with 1-2 oz per gallon. (A little more than a quart per 20 gallons.)

All glyphosate should be mixed (unless you buy the premixed version) per the label to end up with the same % in water for the intended application.
Since there are various concentrations or % of the active ingredient glypho you can buy.
You can't compare the ratio someone else uses due to not knowing what strength the other person bought.

Unless you guys have sprayed commercially, like for a co-op, or on a farm... "professionally", you have no idea. Sorry. I know George and John know, and I have sprayed a fair share also. The stuff you can buy without an applicators license is piddly in comparison. "Commercial" Round-Up will burn down in just a day or two, and be solid dead in 5 and the mix rate is way different. I don't get too concerned with the mix rate on the bottle of Round-up from Walmart or TSC. It's pretty weak stuff really.

Who are you referring to?

Im not offended. Just a bit puzzled. Glyphosate is made up of compounds, "commercial" or not. If the concentration is the same, it doesnt matter what the grade is so long as you compensate for it in a mixture and the compounds are the same. Im not going to try to justify myself here because arguing online is silly to me, so I wont go into detail of what properties I have kept up, or the acreage I have used this stuff on. I dont work for a co-op but I didnt see that as a prerequisite in the users manual for the stuff Ive sprayed. I will however tell you that I know full well what I am talking about when it comes to using herbicides.

Ive got a lot of respect for in regards to tractors. You know your stuff. But please dont assume that everyone on this forum is incompetent in regards to every topic you are knowledgable on. Some of us do, in fact, know a thing or two about agriculture as well. What "commercial" glyphosate are you using? Just curious.

I wasn't talking to anyone in particular. I just thought it was funny what both you and Double07 were saying about mix rates. Double07 is right. You have no idea what concentration George was referring to that he mixed. The stuff you buy locally is a low concentration. I've shot some of that stuff dang near strait and it took forever to burn down. I don't know how to refer to "commercial" grade concentrations other than to just say that. You can't just walk into your local farm Ag chem company and buy a 2 gallon jug of Round-Up (glyphosate). They won't sell it to you, because you have to have an applicators license to buy that concentration. Even though you can buy Round-Up at Wal-Mart.... you can't get the "good" stuff.

I have to assume in a topic like this that people are ignorant. Soooo many herbicides are available to the general public now that anyone who uses them assumes it's the same stuff that gets sprayed on a field..... it's not. Nothing to debate.

I dont disagree. There isnt anything to debate. The 2 gallon jug i have in my hands right now is considered "commercial". Its a 41% mixture. I never challenged George as to being incorrect. But a 1 to 40 ratio (2 qts to 20 gallons) is a strong mix in ANY concentrate of glyphosate. Even the dinky WalMart brand. Ive never seen a solution different than the 41% because we have always needed bulk and have always used the good stuff. And I dont buy roundup. FarmWorks is the brand we have always used, but regardless, its a 41% solution. Its the same chemical, just about half the price of round up. Either way, back to my point, Ive mixed between a 1 to 100 and 2 to 100 ratio, and have never had any issues killing everything it touches. Again, its not a debate. I enjoy these conversations. I just dont think its a good idea to generally say that folks dont know what they are talking about.

Round Up Pro concentrate available in 50.2% at least.
Glyophosate isn't as regulated as it once was either.

There are a lot of other things in the farm grade concentrates also.

So now you're calling me ignorant? Hey, I'm just not educated on the subject. :biggrin2:
That's why I asked at TSC to help me with what to buy to kill the grass and weeds in my driveway because I wasn't sure. Like I said, the first guy sold me Amine 400 2,4-D. That didn't work. The second guy sold me Barrier. After the fact, I looked at reviews for Barrier. It had more 1 star than 5 star reviews!

Ive seen the pro, but cant justify the cost. The FarmWorks we buy kills everything from milkweed to pine yearlings. Another thing, and yall are gonna give me hell for this, but I wear chest waders when I spray this stuff. You guys can say what you want, but overexposure can cause serious illness.

Im pretty sure he was referring me as being ignorant:beerchug: lol. Its all good though. I dont know JMech personally, but I think he has good intentions and always seems to genuinely want to help, although he can be harsh as hell at times.:biggrin2:

In this day and age, they say anything can cause cancer. It's worse in California. I'm not sure if it's the sun or what, but I've read the labels. If you live in California, you have to be more careful.

Glyophosate is pretty safe. Even the EPA says it's not carcinogenic to humans. I think you worry too much.

LOL!
No, you know I wasn't. But in all fairness, ignorance is bliss I hear. :biggrin2:

Honestly, the people working at TSC aren't exactly agronomists. They just know they sell herbicides..... probably think the only difference is the price!

I'm not sure why anybody would want to kill weed, you know what that stuffs worth?:biggrin2:

We don't buy tractors from the big box stores so why would anyone buy other stuff....it is garbage. I go to Ewing Irrigation (a commercial irrigation supply) and purchase the "Pro" stuff. https://www.ewingirrigation.com/cata...U8IPU49kGCk%3D I'm not sure how much better it is than the box store stuff but it works pretty good for me. + the person selling it to you wasn't flipping burgers at McDonalds last week.:biggrin2:

Roundup QuickPro is a tad over 73%.

There we go. Thank you. I couldn't find it, and I didn't have any jugs around to look at.

Well, I did admit in post #28 that I wasn't educated on the subject!

That's just it. I'm not a farmer or professional. I just want to get my gravel driveway back. I appreciate all the comments! :Thanks:

You know what? The grass is dead where my dog pees. Just sayin' :bigthink:

That's definitely news to me.

I do, but only since I've had kids. Worrying used to be something I never worried about. :biggrin2:

Now that I've got two boys, I see everything as a safety hazard.
