How much of the product do you mix with a gallon of water

This question is from 1 gal. Grass And Weed Killer Glyphosate Concentrate

I have noticed that several of the weed killers that I have purchased before have had several
variations of product per gallon of water depending on the strength needed. For a more thorough
kill it might be suggested to use more product--would anyone know how many ounces is needed
for the most effective mixture.

Answer: 
OK, so maybe I'm wrong, but the calculation should look like this, assuming 41% concentrate, then
in 1 Gallon of water, if the amount of glyphosate was to be 2%, then
(.02 gallons glyphosate [=desired 2% solution to apply]) * (128 oz per gallon [by definition]) * (1 oz. concentrate per 0.41 oz glyphosate [for 41% concentrate]) = .02*128 *(1/0.41)= 6.24 oz of concentrate.

"Units Cancel" Check:
Gallons Glyphosate * (Oz Glyphosate/Gallon Glyphosate) * (Oz. Concentrate/ Oz. Glyphosate) = Oz. Concentrate
So, for 2% Glyphosate Solution, 6.24 oz. of .41% Concentrate per gallon of water
for 4%, multiply conentrate by 2, so 4% solution requires 12.48 oz. of concentrate per gallon water.
And so on.
Is it possible that it wasn't working as well as RoundUp because you weren't really applying the 2.0% concentration that is in the RoundUp product? As a double check, I looked at the two 41% concentrate refills for a 1 Gallon Roundup container with the battery pump and guess what? They were each 7 oz. bottles. So there you go.... Read Less

Answer: 
Mix varies on what type of weed you are trying to control. 41% is the active ingredient concentrate.
If you look at ready mixed products like Round-up the concentration is 2-3%. For the same results you need to use 3-4 ounces of the 41% per gallon water. For general grasses you can go with a lower concentrate and use 1.5 - 2 ounces per gallon water. It is just a dilution calculation.

Answer: 
Manufacturer recommends: 1.5 oz (3 tbs) per gal. of water for general weed control and 2.5 oz. (5 tbs.) for tougher weed control.
(FYI: I used a 2.5 oz. in a battery operated sprayer and it didn't work. Then I upped it to 5 oz. per gal. and it still didn't work! I just poured full strength on a couple of weeds to see if it will kill...still waiting.)

Answer: 
Yes, Glyphosate is effective against blackberries. HOWEVER, you must apply it in the fall, when the plant is returning nutrients to the roots. Applying it earlier in the spring or summer will not be effective!

Answer: 
This is a very strong product. If you saturate the ground around the plants, it should pretty much kill the roots stopping further growth for around a year. Treat the area when you are not expecting any rain for at least a few days for it to be most effective. It will kill any grass or vegetation in the area, so careful application is needed.

Answer: 
Yes. Unfortunately it won't eradicate it without repeated applications. If you're trying to protect Bermuda grass don't use glyphosate - if you aren't, water it well, don't mow for a week to allow a lot of leaf growth, and spray regrowth again in early fall when it's storing food in the roots. It will probably take two years.

Kills most brush, no problems if used with care. Low persistence in water, longer in soil that might wash in (but it is tightly bound to soil) and on dying vegetation (clear it out). The "other ingredients" (wetting agents) are actually more dangerous than glyphosate itself, but neither is very toxic to birds, mammals, or fish.

...More toxic (but not dangerously so) to amphibians, especially in shallow undisturbed water near shore where animals might also drink - but you would have to be very careless to reach harmful concentrations spraying diluted product.
...Cut back brush over 18" to speed control and minimize overspray & runoff, then let it resprout since this is absorbed through the leaves. Anything 1/2" or thicker might be easier to kill by painting or dripping some specialized product onto the cut stem, but that's another story, and this will do the job though it may take more then one application.

Rated 4.0 out of 5.0 by Good Weed Killer I read many reviews stating the this product would not kill weeds.. Well it does quite well, but it takes longer to do so than Roundup. I also increased the dose to 6oz per gallon from three. It takes about 14 days to kill the toughest weeds. Broad leaf weeds will wither within the seven day period, but sage, and some harder to kill weeds will take two weeks. For the price when compared to Roundup this is a good deal. I would, and will buy more when needed. May 17, 2016
