I had a 250’ foot wood privacy fence built behind a house I own. The treated fence pickets go down to an inch from the ground. There will be small children playing inside that fenced area in a year or so. No outdoor animals. Edging both sides of that fence with a string trimmer is a pita.

What’s the longest lasting, safest product to “edge” that fence with, inside the yard and out?

-Roundup?

There are plenty of generic products identical to Roundup. I’ve seen no advantage to paying a lot extra for the brand name.
 
You guys may be having much better performance from the Roundup or generic glyphosate products than many of us are in the agriculture sector. I've been extremely disappointed in the lack of performance under fence lines, around farm buildings, etc., etc., these last couple of years.

For many years we could use a 1 oz/gallon rate and see awesome performance. Some areas this year we were using 3-4 oz/gallon of both 41 and 47% glyphosate and having to spray 2 and three times to get a total kill.

Just responding with my experiences.
 
It's been a minute since I've looked into the stuff, but I know there's a soil sterilant that you might could look into. Last I saw was in pellet form but there may be some kind of liquid too.
 
Talk to a local farm supply place and see hat the local farmers are using.

A friend who runs the hardware store in the farming community where this house is located recommended Killzall, which appears to just be glyphosphate, i.e. generic Round-up.

There are some aggressive grasses and weeds in this new yard.

The concentrate Killzall is 41% glyphosphate. I shop at this hardware anyway so I may give it a whirl.

We usually mix at a 3% rate of Roundup (we use a generic called Prosecutor) on the golf course for beds and out of the way stuff. If I remember right the label allows for up to a 15% rate in certain instances. I’ve only sprayed out an area of Bermuda at that rate once, but it killed the intended area ”grave yard dead”. There are adjuvants that can be added to the mix, one that comes to mind is called Hellfire, that will speed up the burn down.

I have used this-it works great and fast. It does seem to need to be re-applied more often.
 
50% diesel fuel, 50% used motor oil. Kills concrete. Lasts easily 2 years. Set fire to it a week after a second application and you’ll have bare dirt for a very long time.

Not “environmentally friendly” by any measure, but neither are some of the OTC brush killers.

My dad poured used motor along the fence line to our good-sized back yard fifty years ago. This was back before the invention of the string trimmer, or the HOA.

Back when I was real young (and before the EPA got all big and stupid) my Grandpa had a guy that would spray the dirt road with a used motor oil mixture to control all the dust. He had been doing it so long the buildup allowed it to only need a “maintenance spray” every Spring and Fall. The “fun” thing was just after a rain …it was s l i c k as goose crap! We’d ride our bikes do slide stops and stuff but when in a vehicle you could wind up in the ditch if you got crazy.

Thought you had to be certified to spray that.

It is not restricted use in NC and you can order it on the internet. If it was restricted use, you can get your private NC pesticide applicator license pretty easily. Take the test, pay the annual fee and do a couple of CEU's every 3 years. I've had mine for years.

I go to Lidl, cheapest place to get the stuff. I buy 4 gallons of vinegar on sale for $1.80, and 2 things of salt for $0.38 each. I mix 2 gallons of vinegar, 1 thing of salt in a bucket to get the salt dissolved good, pour it in my backpack sprayer and do it again with the other 2 gallons, and then squirt some dawn in.
And for like $8, I have 4 gallons of grass/weed killer. I see results in a few hours too. Has worked on everything I’ve sprayed, doesn’t contaminate the soil and won’t give me or my kids cancer.
 
I’ve been using Glystar from Agri-Supply for years but I want to try the vinegar/salt/dawn cocktail when my jug runs out. Never heard of that before.

We use too “paint” fences with used motor oil. Some of them have been standing 40 years I know of.

This 100%... I've not bought an OTC product for years. As said, it can be mixed with water to make it go further/spray easier but for how much it costs it's likely not worth it.
 
Remember, glyphosate is a de-foliater, it doesn’t keep seeds from germinating. So if you spray something that’s already seeded out, in a couple weeks, those seeds are gonna germinate. Don’t look for it to keep stuff from coming back unless you buy a ground neutralizer. After you spray initially, check again in a week or so for new germination, then spray that as well. Doing that will get you a longer lasting kill.

just my opinion of course
 
I’m not sure if it’s been mentioned above but glyphosate+prodiamine is an awesome combo. I also add one or two drops of blue Dawn.

The dawn acts as a surfactant and reduces the surface tension of the water droplets. This makes it stock on the leaves better. I usually purchase prodiamine from Amazon.

the prodiamine is granular but dissolves in the tank with water. It will make your weed killing solution the color of a school bus- but man it works.
 
I have heard many of you mention vinegar, salt and Joy.

What strength vinegar? Is stronger/industrial better?

I want a decent weed killer that won’t cause cancer or effect the ground water, especially since I’m on a well
 
They do make a higher concentrate white vinegar and market it as "natural" weed killer.

General heinz vinegar works fine.

I always make it stronger, add more salt than I think I need and spray.

It doesn't work that great on vine weeds(poison ivy as an example). But other yard weeds and garden bed weeds it does a good job.
 
Just grass? I use Bonide Burnout instead of the proven but dangerous Glyphosate. It's basically palm oil and coconut oil in high mixtures. It will cause burning sensations on the skin but not nearly as toxic as the rest.

For broadleaf weeds and vines I use Triclopyr and 2,4-D mixture aka Crossbow or any of the newer tri-way products with Dicamba being a primary ingredient.

Works well so far on the homestead controlling poison ivy and blackberry brambles.
