Weed killer

[CKain(MI)]

Early this summer I had a nice layer of 21AA gravel spread on my driveway. Really like it over the age old 'dirt' .... Now I am getting many sprouts of grass, like Crabgrass or a close cousin. I did not have this before... Glysophate will kill it, however not the soon-to-come new sprouts. What can I spray that kills emerging plants.. maybe Tri-clor ??
Thanks

Boiling water or salt will do the same . I wouldn't use salt noally but on a driveway it's probably a reasonable thing to do .

I tried salt water on my gravel driveway. Wasn't that
successful.

IMO, nothing you can do to a gravel driveway that lasts forever.

I use 8 oz of 41% generic roundup to a gallon of water. It works
for a short time. I also blended 8 oz pramitol to the roundup.

Results are short lived.

Chasing weeds out of a driveway is endless.

My concrete drive works best..

A product called "Barrier" is what you need. It positively stops the germination of seeds. I have used it successfully for a few years now.

Last time I was in my local farm store, The "Barrier" product seems to have been replaced by another product called, I think, "total vegetation killer"

 

[Charles in Aus.]

There was once available a product here called ' Once a year path and driveway weeder ' . No longer made for environmental reasons , salt is just about all that is available in residual controls now .

CaCl solution from old tractor tires if applied heavily will keep vegetation down for 3 years or so.

Could probably buy the CaCl and mix your own. Of course gubmint will shut this down once they get wind of it.

Don't believe individuals can still buy effective long-term commercial solutions.

This is what I use.
Works good and last a whole growing season.
I might be a little prejudice since it is made right here in the town I live in.
RM43 TOTAL VEGETATION CONTROL

That is exactly what I have, but have not yet used any because I still have some of the "Barrier".

Good to know the total vegetation killer works.

Where the tire run in the drive is always clear of vegetation. Between the wheels and where we don't drive much is where the growth is.

I am betting your in Michigan.
What if you got a ton of road salt?
Lay it on like they do on the roads and a bit more.

 

[CKain(MI)]

That should work !!! ;-)

 

[wore out]

Be careful with some of the ''total vegetation killers'' as they can translocate and kill your lawn ''downstream'' from the graveled area where they were applied.

Gordons Barrier and RM43 both use the same active ingrediencies; Imazapyr and Glyphosate; just in differant concentrates
and at differant application rates.

Barrier;
18 fl. oz. per 3-5 gallons of water to cover 1,000 square feet.
Active ingredients: 1.74% Imazapyr, isopropylamine salt; 3.82% Glyphosate, isopropylamine salt

RM43
Maximum application rate of this product is 7.4 fl. oz. per 1,000 sq. ft. per year
Glyphosate, isopropylamine salt 43.68%
Imazapyr, isopropylamine salt 0.78%

So they cut the amount of Imazapyr in the bottle by more than 50 percent and cut the amount of spray you can use per 1000
sq ft by more than 50 percent.

If you were using it on a large area with a measured spray rig it might not work as well.
But us homeowners tend to over apply a product often anyway.

Maybe you cannot get it in your country but USA is still basically free and the yearly killer is available.

Assuming you are in MI, whatever you do, do NOT put salt on your driveway. It is a disaster in the winter. The ground doesn t freeze and you will end up with a muddy rut until summer.

 

[johnofnewhaven]

That's a great point MJMJ. Like
George said it's a never ending
battle. I spray my gravel drives
and lot 2-3 times a year. Weeds
and grass in gravel annoys me
and looks terrible. Lol

 

[Billy Shafer]

Be careful of all weed killers. Evan the Agent Orange ones. That they said were harmless. I can show you my bills. That prove them wrong

 

[Hay hay hay]

Drive on it. Make it a 2 track. Tires will kill the tracks. Mow the center. A manicured 2 track driveway is a pretty sight. No need to kill the center.
Let it look like a farm!

Billy, How are you doing? I hope your prognosis is better than mine.

Next time you redo your driveway could you put down several layers of heavy weed-stop fabric down before you spread rock on it?

 

[Billy Shafer]

I am learning to walk now. Made it across the yard and back. Then rested for an hour. Have another vet walk with me. Sure glad the VA says I am not sick.

Best idea

Here in NH the road salt keeps the first twenty feet of a gravel drive clear of weeds.

MJMJ, how many lbs salt / 100 lbs. gravel does it take to keep a compacted gravel driveway in MI from freezing?

 

[MJMJ]

I m sure you know there is no specific answer to that. But in my experience, its less than it would seem.

I guess it would if there is a dam of frozen ground and snow and ice keeping the moisture from draining away from a poor driveway base.

The salt dissolves and soaks in the ground, it doesn t need to be damned up or even flat. A small amount in the summer may be mostly gone by winter. But too much will make a mess. I ve done it, it sucks. Used a couple bags to melt ice one the driveway years ago, the muddy ruts lasted way longer than winter.

Ahhhh. I've always let spring warm temps take the ice away.

When our pecan trees were little , we mixed roundup with pre-emergent. I thing it was called WD75. The mixing instructions were in the round up booklet.
