Spraying weeds in driveway?

Geo-TH,In · Jun 9, 2021

I used backpack sprayer to spray driveway. The gravel was recycled from property I recently sold. There is a lot of dirt in gravel. It makes a good road base. Also make a good seed bed for weeds.

I used a blend of roundup and 24d.
As you can see there's a few broad weeds that are some what tolerant to my mix.

So what chemicals do you use, # oz per gallon?

What weed killer do you use on lawn?

From what I see of the picture which is a bit blurry 24D should clean it up good. For the broad leaves. If there is grass I would just drive on it more and all of it will go away from use. I have weeds/plants growing in my drive now. Mostly from lack of use by the shed. When I was using it regularly it didn't happen.

3% Roundup and 3% 2,4-D should kill just about anything. What was your recipe and how long ago was it sprayed? Roundup takes a good week to kill tougher weeds. 2,4-D will show in a day or so.

Mix 24,D or Triplet or Trimec at the rate of 1.5 ounces per gallon and Roundup at the rate of 1.5 ounces per gallon together. Give it 10 days for a decent kill.

I've had good luck with Ortho Weed-B-Gone, your batch size probably different than mine but 1 quart to a 14 gallon sprayer. I've tried 2-4D Amine 400 and 2-4D LV400 with only poor to fair results.
After the broad leaf weeds are gone, hit anything left with ROUND-UP.
The companies have all really slowed down the rate that weeds wilt & die after spraying. I used to spray 4-5 14 gallon batches in an afternoon and the stuff I sprayed with the first batch would really be wilted before I was done.I guess the problem was the leaves died but not the roots and weeds grew back, the slower kill killed the whole weed.
Think my BIGGEST day spraying Round-Up on my 2+ acres was six 14 gallon batches. We had hundreds, maybe thousands of square feet of crushed granite ground cover around the house. With enough dust settling into low spots grass/weeds sprouted and I'd have to spray 4-5 times a year. I finally got 90+% of it scraped up and neighbor tailgated it in his barnyard. I'd spray around every tree, bush, anything I had to mow around got a circle of Round-Up, saved a boat-load of time trimming when I mowed. Now I have a few places my 54 zero turn mower deck just won't fit. Ha-Ha, the 60 inch would have been worse! I've got about 6-8 dead trees to cut, two Elm's and 4-6 evergreens. That will save trimming time.

I have been using the RM-43 Total vegetation control. It is Roundup + Imazapyr. Supposed to kill everything for 6 months or more. I put it down about a month ago and it seems to be working.

Currently, Weed Be Gone has dicamba in it as one of the active ingredients. It will drift after application. It can ruin melon's/pickles/squash/beans and other veggie crops. Be very careful with it. Jim

jimg.allentown · Jun 9, 2021

I use a weed burner.

Since I have a well, I will not use toxic chemicals on the ground. Those chemicals are designed to kill things. I may well be one of those things it kills. I'd rather not roll the dice with whether or not these things will kill me or cause some form of cancer or other dread disease.

big jt · Jun 9, 2021

Use some sort of Glyphosate at a quart to the acre on drives (quart peer 20 gal in my case). Your larger weeds look sick and it takes a while to do it's think on larger weeds.

As to the lawn I use Confront. Does wonders on Alsike white clover and is pretty gentle on ornamentals as far as drift. Stuff is about $120 a gallon but you are supposed to apply at a pint to the acre.

Looks like it is not killing your plantain, did you put enough 24d in the mix, it should have done it! Round up won't kill it alone!

Geo-TH,In · Jun 9, 2021

What concentration RM43?

charlie n · Jun 9, 2021

40 oz. To 55 gallons of water. Sprayed sod fields with it. Use it in my yard.Good stuff. And it will mix with roundup.

Pramitol

Geo-TH,In · Jun 9, 2021

You may be right. I was mixing 2 oz roundup and 1 oz 24d per gallon. I like experimenting using least amount of chemicals.
I'll try 2oz of each next time and go from there.

Some people responding are using about 2x that much.

MARK ROBKE · Jun 9, 2021

George-I put in a 500' long driveway and used new gravel over filter fabric. After a few years I had the same problem with weeds. I can spray roundup @ 3oz per gallon on it 3 or 4 times a year and it kills everything but more grows back. A long time ago I used Pramitol 25e and it worked ok but I reverted back to roundup/glysophate. This year I used pramitol and so far so good-nothing has grown back yet. Pramitol only needs sprayed once and it sterilizes the soil for a year. The kicker is you need a rain just after it dries after you spray it. The rain soaks it down into the earth. You do not want a gully washer rain, just a gentle soaker not too long. It can leach off the sides and kill grass that you don't want killed if there is too much rain. But you only have to spray one time a year, and that is the second best part. The best part is not having all that yellow dead stuff in the gravel all year long. Mark.

Vicinalvictor · Jun 9, 2021

I don't use any of that toxic stuff around the home. I would either get the driveway paved or use a non toxic organic solution.

SVcummins · Jun 9, 2021

Up the rate a little bit

jm. · Jun 9, 2021

I have been using 3 oz roundup an 2 oz 2/4d under fences for years ; Most time can get by with 2 spraying unless a lot off rain . The wildlife refuge being on three sides off this farm makes it where I really have to watch what I spray .

Geo-TH,In · Jun 9, 2021

Jm.
I'll try you mix rate Saturday when it stops raining.
Use pole barn floor to test coverage with just water. I think I'm close to getting 100%.
Adjusting pressure and speed.

MARK ROBKE · Jun 9, 2021

You really should not use any pesticide at a lower than recommended rate. That is what make weeds immune to the pesticide, when the pesticide is not strong enough to kill. I think most are recommended to be 3 or 4oz to the gallon. It is on the label, and I always use the higher rate to prevent immunity. And they recommend how wet to get the plant on the label too. I would still recommend pramitol above any thing else. Mark.

Geo-TH,In · Jun 9, 2021

I have a lot of roundup, 24d and RM43, Planning to use it up before buying anything else.

grizz02 · Jun 9, 2021

Are you using surfactant in your tank?

Fred47M · Jun 9, 2021

I know you have inventory you want to use, but I do is dump 2 gal ortho ground clear, run 10-12 gal water in tank. Spray it, (my drive was worse than yours). Forget about it for about year and half. Not cheapest option, but no real mixing, guess work and just clear and flush tank once and done.

jm. · Jun 9, 2021

I swear I tough we were talking about weeds not bugs LOL how about herbicide . Primatol is fine if one can get it down but in a hard rain it trans- locates easier.

fixerupper · Jun 9, 2021

Here is the farmer's mix I use if I want to kill everything. This is for a 2 1/2 gallon pump sprayer; one glug glypho, one glug 2-4D 4, one glug MSO (methelated seed oil) and a half glug Optima, which is a surfactant\water conditioner. The weeds and grass will be beyond sick. For broadleaves in the lawn we have to be more scientific, 2 oz LV4 or 1.6 oz LV6 2-4D per gallon of water with nothing else added.

Vinegar ,so I have been told ,kills weeds. Never tried it.

johndeerejim · Jun 9, 2021

I used to use Roundup but it didnt keep the weeds gone for long. For years I've used Spectracide concentrate in a 2 gallon commercial sprayer. I mix it heavy, slightly over 2 cups and fill then spray. Works really good. My neighbor gets stuff from Family Farm and Home for the fence and it works really well, cant remember what he calls it. This year I was going to Preen my driveway but spring arrived three weeks early and I didnt get it done. Bought some Spectracide few weeks back about time to use it once we get some dry weather.

Hay hay hay · Jun 9, 2021

I like the look of a 2 track. I use Crossbow to kill the weeds, then the vehicle traffic kills the grass in the tracks and I mow the center.
It gives it a farm lane look.

bc · Jun 9, 2021

I use the same thing for the drive that I do for fence rows after the pigweed and other weeds get over 6' tall. Have to check the mix out in the barn tomorrow but basically 2.4.D Amine and 41% glysophate/roundup. Both are mixed at the label rate listed for railroad tracks and woody brush. Since that is slow knocking down the tall weeds I started adding a cup of Tordon rtu that I use for stumps. The tordon starts knocking down those tall weeds in a few hours. I don't spray enough on the ground for the tordon to run off or affect anything important. Between all the rain, wind, and everything else going on, it doesn't take long for some of those weeds to grow from 1 to 6' tall. Every year I say I'm going to stay ahead of the weeds but things keep coming up and then the garden is downwind of the weed patches.

Most of those two products are not compatible together and can cause antagonism, only specific types should be mixed for effectiveness. If anyone wants to use both, I would suggest getting the right products first. These two chemicals have different mechanisms of killing plants, and one can hurt or hinder the performance of the other.

Glyphosate needs a living/growing plant to work. This chemical is absorbed by the plant and carried to the growing part of the plant. This process typically takes 1-3 days, the reaction is based on how fast the plant grows.

24d is much faster acting, the plant absorbs this chemical and within 1-4 hours halting photosynthesis. This reaction is rapidly killing the part of the plants that would need to be alive to carry the glyphosate into the growing part of the plant.

Brown Swiss · Jun 9, 2021

It's kinda like the whole a square is a rectangle but a rectangle is not a square, we go through pesticide applicators class of which herbicides fall under being a pesticide! Since weeds are a pest! Have some cousins in that same category!

Traditional Farmer · Jun 10, 2021

You sure find a lot of things to worry about.

The entire reason for mixing the two is that they work on different types of plants. Gly works better on grasses and 24D works on weeds. If a weed is already dying from 24D, we don't need to worry about if the gly is having it's full affect on it.

MARK ROBKE · Jun 10, 2021

Well- a weed is a pest-right? LOL!! But I meant herbicide ! Mark.

rustyfarmall · Jun 10, 2021

If you want to do it just once per year, add some "Barrier" to the glyphosate/water mix. Barrier STOPS seeds from germinating. Glyphosate kills existing vegetation right down to the roots.

Don't be stingy with either one.

Hoenes · Jun 10, 2021

Yep. Online recipe calls for 1 gallon of white vinegar, 2 cups of table salt, 1/4 cup dawn dish soap. Kills driveway weeds and weeds in sidewalk joints.

I tried that once. Had NO effect on the weeds and grass, but it did make my driveway smell like pickles.

Don't worry, we all knew what you meant. Now just give yourself 50 lashes with a wet noodle. Then blame it on spell check the next time. That said, I have spotted a bug or two in the past and the only thing handy was a spray bottle of weed killer to spray on them. Wd40 and carb cleaner spray will also take care of some bugs too. Found a pack rat inside a heater and he got a full shot of carb cleaner in the face and off he went.
