Weed Killer Recipes

[Arbo]

Common vinegar, and disolve all the table salt you can in it. Spray it on the offending flora, and they will be dead the next day. Be sure to clean your sprayer thoroughly...This stuff is highly corrosive if left sitting in your equipment.

I was just referred to this thread, so I hope someone is still looking. I bought the concentrated Round-up at Lowes, about $158 if I recall. So that damage is already done. My question, like a typical guy, is there any benefit to adding any or ALL of the previous suggestions to the dilted Round-up? I probably don't want to fool with the salt because once the weeds are gone I'd prefer some grass to come back. However, I have about 15 acres of woods on the back of the farm that have a solid "carpet" of poison Ivy. I want that stuff dead, but don't want to destroy the trees.

Thanks.

I second (or 3rd or 4th) the recommendation to be wary of salt where you want things to grow again. Also, be wary of wherever you are putting salt at for the water path, it will carry through the ground.

I went biblical on my grand mother's gravel driveway years ago. I dragged up much of the gravel, slightly turned the ground, and poured several hundred pounds of salt in it, covered back up with gravel, and compacted. Wouldn't you know it, no weeds in that gravel driveway for Years. Of course with the rain washout, there was also no grass along the driveway. This displeased my grandmother immensly.

I thought I did her a favor so that she wouldn't have to weed her driveway again. Lesson learned, and probably overkill with as much salt as I put in there. Its kinda funny now.

Yeah, that runoff thing will get you and salt doesn't really break down the way that stuff like Round-up seems to. Your stuck for a while. I have also been told to let it be right now since it's not actively growing and hit it hard in the spring. Maybe that's the best option, and in the winter while it's dorment I may be able to get the bulk of the stuff out of there.

Also try adding a teaspoon of dish detergent per gallon to your sprayer. Works as a sticker and the generic gylphosphate (Round-up) will work better. Make sure you add the detergent after filling up the sprayer or you'll have a mess.

I've heard that for years too but oddly the generic of Round-Up I bought in a 2.5 gallon jug specifically says to NOT use detergent or soap as a wetting agent...it says to use ammonium sulfate if one is needed and to mix it thoroughly in water before adding the glyphosate.

I have a permanent area where I did not want weeds. It is a space between our patios and a stone wall that defines the end of lanscape. It's pretty long 120' x 20'. We did not want grass either. We put down black non woven weed fabric and covered it with 3 inches of 3/4 gravel. Works. Very little grows, Combination of too hot, no dirt. But I am pretty sure we will have to blow the leaves off in the fall. We use Round up to touch up but I think we are going to switch to vinager. We used Round up on 12a of poisen ivy . We have found that Round up does not work on everything. Horse tails grow through the blacktop and Brush Begone is the stuff for that.

That sounds like a recipe I found online, Never had a chance to try it yet though.
If it works on poison Ivy Im sure it will work on weeds!

Poison Ivy Vegetation Killer
1 cup salt
8 drops liquid detergent
1 gallon vinegar
Combine the salt and vinegar in a pan and heat to dissolve the salt. Cool the vinegar, add the detergent, and pour some of the liquid into a large spray bottle. Spray the vegetation. (You can also just pour the mixture onto the weeds.) Refill the spray bottle as necessary. Note that this formula will kill all the vegetation, so make sure that you are only spraying the plants you want to kill. If you need to use a lot of this spray, avoid spraying it near wells, as the salt can leach into your water supply.

Sounds like the Brush Begone would be a good option for me then. I want something that will do the job, but I don't want to destroy the soil in the process. I still want the good stuff to be healthy (meaning the larger trees) and I want grass to be able to come back in some places.

Just wondering if anyone out there has made their own weed killer, I have alot of weeds and grass to kill in the summer and the round-up is just getting to expensive.

How much RoundUp do you go through?

A 2.5 gallon of Pro Concentrate costs about $150 and makes 125-200 gallons of mix (1.6-2.5 oz/gallon).

 

[Spiveyman]

I read the directions with my Round-up Pro and for the type of weeds/brush I have it recommended 5 - 10 % solution. I used about 10 oz per gal (40 oz in a 4 gal sprayer). Not sure about yzbdsbp, but at that rate I will go through this stuff pretty quickly. Even still, it's worth it if it will get the job done.

The best poison ivy killer I know of is Brushbgone --active ingredient is Triclopyr. Just wet the leaves--don't soak the tree bark. May take repeat applications a few weeks apart to get the plants you thought you got the first time.

As stated above-don't burn it or you can get it in your lungs.

Well a good rate for weed killers is about one quart glyphosate per acre, you chose the brand. mixed with about 15 gallons water. Roundup is 48% glyphosate and the generic is 41% and use the same amount of 2-4-d amine mixed in with the glyphosate and you will kill everything..

I sprayed Tuesday, but it rained off and on Tuesday - Thursday. That will either wash the stuff off and my $$$ along with it, or it will get it growing again and kill a bunch of it. I'll give the Brush Begone a shot after I'm out of the Round-Up Pro.

I mix my own based on reading the label for Roundup Brush Killer. It's 2% triclopyr and 18% glyphosate and they recommend mixing it at 6oz. per gallon for spraying. It's $40 a quart at the hardware store.

On ebay, I bought a 2 1/2 gallon jug of 41% glyphosate for $51 and a gallon of 8.8% triclopyr for $45. After doing a little math, I figured that if I mixed two gallons glyphosate with one gallon triclopyr, four ounces of the resulting mixture would have the same active ingredients as six ounces of the Roundup concentrate. So for $96 I made 3 gallons of mixture, which will make 96 gallons of spray. It is equivalent to 18 quarts of Roundup brand brush killer, which would have cost me $720. It's also equivalent to 72 bottles of ready-to-use, which cost $18 each, or $1296.

Plus I have a half gallon of glyphosate left over to do with as I see fit.

 

[Lindblom Lawn Care]

I seen 41% glyphosates, a 2.5 gallon jug for $60.00. At gallon of 2,4D and ester runs me about $18. has 65.5% active ingredient.

 

[Spiveyman]

I have another question here. Sure enough I have checked the fence line all week with little sign of any effect of the 10% solution of Round-up. Will that stuff even work in the fall when the weeds aren't as active? Will any of the other ideas out there work when the weeds are less active like now?

Thanks

As I recall, usually you will see some planting wilting a few days later, but it takes about 2 weeks to go brown.
