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.)

There really is no uniform, all purpose mix ratio with these products. A lot depends on soil structure (loamy, clay, rocky, etc), and the type of vegetation you are trying to get rid of.

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.

This product is a broad spectrum defoliant. It will kill or harm any plant life. Be very careful of overspray, as the smallest amount of this product will kill many plants. Be very aware of rain water runoff. Small amounts of this product washed off treated foliage can kill nearby foliage.

Glyphosate salts are, by design, "harmful" to virtually ANY green plant. If it is sprayed on or near a plant such as roses, it MUST be below the part of the plant with the green leaves (i.e.: the trunk/stalk is OK). It is best to cover the leaf part of the roses with paper or plastic while spraying, making sure that no spray gets on the leaves. If you have over-spray, it must be washed off promptly Read More

Rated 4.5 out of 5 by 137 reviewers.
Rated 5.0 out of 5.0 by 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. September 3, 2016
Rated 5.0 out of 5.0 by Great Product !! Does a very good job on stubborn weeds and regular grass. September 6, 2016
Rated 5.0 out of 5.0 by Killer Product..Kills all grass, plants, weeds Steps to use: Spraying on Sunny, calm wind Days is better Mix 1 gallon with 6 Oz, I used 18oz concentrate with my 3 gallon water spray (get the job done once, it did for me :) Mix Liquid washing soap, like 2-3 oz, this helps to stick the product even better on grass, weeds, etc. Spray Generously, Give it 7-10 days to work, spray with caution as whatever it gets prayed on will kill it, even small sprouts coming from tree trunks, yes!! August 24, 2016
Rated 3.0 out of 5.0 by A little better than "You get what you pay for" ...A plant cut down lying on the ground can still be trying to bloom or even ripen seed. If just sprayed or frosted, sending nutrients to the roots as well. This works so slowly that with quick-seeding annuals or deep-rooted, hard to kill perennials like dandelions or bindweed, you might be getting behind the curve. ...Works faster on broadleaf weeds - and some like the two above you don't necessarily want killed overnight (allowing systemic herbicide to translocate underground). But annuals are putting so little energy into the roots that killing top growth is often enough to also "kill the root". ...Even expensive name-brand glyphosate now includes a little contact herbicide so you don't have to wait a week to see what you missed. On unstressed annual grasses it may take 10 days to see visible results from this product - you might even have to mow again before crabgrass, foxtail etc are finally killed. ...I'd recommend spraying & touching up with Spectracide to see total coverage and kill (or at least weaken) weeds in a few days, then using this on any regrowth. Definitely don't depend on one product: herbicide resistance is real, and you can learn all about it at home. August 30, 2016
Rated 5.0 out of 5.0 by Best value This was the best value that I found for 1 gallon 41% concentrate. It works well and is economical to use August 23, 2016
Rated 5.0 out of 5.0 by 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.
