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.

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).

...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.

1 gal. Grass And Weed Killer Glyphosate Concentrate is rated 4.5 out of 5 by 144.
Rated 5 out of 5 by from Awesome Weed Killer The first time I used this product I followed the label directions to mixed outcome. After that I apply at 5.5 - 6 oz per gal( same as the big R) KILLS EVERYTHING! It well take up to 2 weeks on the tough stuff , but it definitely does the job. I use an Ortho hose end sprayer and routinely use it every 2-3 months on the perimeter of my property( 1/2 mile square) to keep the weeds down. It works 100%. I found that keeping the weeds down removes habitat for insects & predators, so that is an added benefit. Let's see the bugs develop an immunity to that! Highly recommended, easier on the environment than pesticides, & a much better price than the big R.

Rated 5 out of 5 by from Amazing!! I bought this concentrate last year to help kill the weeds that were invading my gravel drive. After the first application, it took about 2 weeks before I could see the color slowly draining from the weeds, by 4 weeks everything that was touched was DEAD!! I kept up with it once a month and could not be happier. You do need to watch where you spray because it will kill any type of plant, weed or otherwise! If you need a product you can count on, this is it! Don't expect overnight results, but one application per month is all it takes! Patience is key and this product is AMAZING!!

Rated 5 out of 5 by from Excellent price, excellent effect I have used more expensive weed killers, but have never found a better buy than "Compare n Save". The weeds take about a week to die, but they die, and they stay dead. In about three months, new weeds will appear, but I believe they are new weeds, not the old ones returning.
