Looking for a spray chemical that will actually kill vegetation and keep it dead for more than a month. Have tried Round up and Spectracide and the common chemicals sold in Walmart, Lowes etc. I don't have any flowers or animals, I want something I can spray around my fence and driveway and kill it off. I was told Amine 400 was good. Thanks for any recommendations.

I've had good luck with Ortho Groundclear It lasts about a year when I use it.

I use a mixture of Round-up,, Spectracide,,, & Ground Clear...and liquid Dawn dish soap---- and i make it a tad more concentrated..wait 7-10 days and repeat-- total annihilation...daffy

If you get licensed as a private applicator by your county, you can buy glyphosate concentrate. Roundup is actually mixed to a pretty low level of active ingredient (glyphosate).

It’s doesn’t take a big effort to obtain that private applicator license.

I am about to kill off a small field of poison ivy here. The other weeds will just be gone as well. Mix up a strong batch of white vinegar, lots of salt and a healthy amount of cheap dish soap. Don't skimp on any of the 3. Lots ! It takes a few days but the leaves begin to brown and wrinkle away. Just be sure there are no rains for a few days.

Dawn has a power wash liquid which is very strong. Sprayed on weeds full strength, it kills everything. Not good around your trees or plants you don't want to kill.

For total vegetation control, I use Ragan & Massey RM43 which can be found at your local farm & ranch store. It's a glyphosphate concentrate mixed to 43% rather than the Roundup "concentrate" (19%) you'll find at Lowes. Definitely use a surfactant to help absorption and prevent the wind from taking it to areas you don't want to kill.

I have read that soaps are generally ionic surfactants which may interfere with absorption of herbicides. I have also read that Dawn liquid dish soap or baby shampoo is cheaper and just as effective. YMMV based on what you are applying and how it interacts with ionic surfactants. For me, when I spend $149 for 2.5 gallons of RM43, I also spend the additional $12-$20 for the ag-use surfactant which is non-ionic.

For a small fee and included transportation, I could have XD45MANjr come over. He's 6, but everything he pees on dies and stays dead.

Ruralking sells both 41% and 53.8% glyphosate concentrations. No license necessary here. Tractor Supply is similar.

You need very little Dawn as a surfactant.

Just enough to break water tension so the vegetation is "wetter" rather than beading up as most vegetation has natural oils/waxes that protect them by beading and shedding water.

Put a few drops in a quart of water and spray on a plant and you will see how little it requires to be effective.

I use Farm General 41% glyphosate and BK-32 Brush killer and I sprayed during our "spring growth" in March.

I go after poison ivy anytime I see it.

Do you think the farmer could afford the Lowes or Home Depot prices?? Go to the Tractor Store:

Some of the weed killers come with a spreader/sticker surfactant or use Miller Nu-Film 17:

I get mine from our Farmer's Co-Op in concentrate.

If you want to try this, go to a store like Home Depot and by “30% vinegar,” stronger than regular home use.

I purchased RM43 from Tractor Supply. It has the same active ingredient as RoundUp, but has another that prevents new weeds from growing.

It has surfactant in it, does it need more?

From their FAQs:
“What should I do if I left some RM43 out and it froze?
RM43 should not be left to freeze, but if it does happen, shake it up well because in extreme cold the surfactant may separate from the mixture but it will easily go back into solution with agitation.”

I’m traveling now but don’t bother going to HD or Lowe’s. Go to a commercial groundskeeping supplier and ask for the best product they have.

I did this last year and the stuff they sold me just flat out works. When I get back home midweek I’ll try and get you the product name.

Is your bottle of Roundup new?

The reason I ask is that thanks to EPA and lawsuits, the current Chemical in the round up bottle is not what it used to be. It used to be glyphosate and a watered down version (~20% concentrate) of glyphosate at that so that they could sell you water (i.e. even before the generic glyphosate was a better value since it was sold at 41% concentration). Now, round up as reformulated to be:

Triclopyr, triethylamine salt 2.50%

Fluazifop-P-butyl 2.00%

Diquat dibromide 1.50%

You can still go to tractor supply, ace Hardware, and other non-big box stores and buy 41% glyphosate. Adding a surfactant (e.g. Garden product actually labeled surfactant), a sticker/spreader, liquid Castile soap, or Dawn dishwashing liquid makes it even more effective.

Grasses and most broadleaf plants are easily controlled with glyphosate. However, woody stemmed weeds are rarely effectively controlled. Triclopyr is much better at controlling woody stemmed weeds, and the original Roundup Poison Ivy Plus Tough Brush Killer contained it and so does the current version.

Thanks everyone for your replies. I went to Tractor Supply and got a 1 gallon jug of 41% glyphosate it was on sale for $39.99 supposed to make 85 gallons. Added a squirt of Dawn mixed it up and put it on. I will know in a couple months how good it works. Or maybe need to look for Agent Orange.

Harris extra strength vinegar in a sprayer works better than the Roundup or other chemical sprays. After years of Roundup I discovered this a an old-time hardware store and wow!! It works!
