Customer Reviews

0.5 Gal. Weed and Grass Killer Super Concentrate is rated 3.9 out of 5 by 74.
Rated 5 out of 5 by from The Best Way to Apply Herbicide There are two kinds of herbicide: one that kills weeds but does not harm grass, and one that kills everything. It is very important to know what kind you are using. This is the second kind - it kills everything, so keep it away from your lawn. * The chemical name for this herbicide is glyphosate, it was discovered in the 1970s, and has revolutionized agriculture. Farmers use it to clear weeds prior to planting. It inactivates on contact with soil, and breaks down after a few weeks into harmless components. Glyphosate is no more harmful to humans than most of what you have under your kitchen sink right now. It has no particular effect on animals, and is actually consumed by bacteria. Look it up ( do that for any chemical you plan to use ! ) RoundUp is the original glyphosate formulation. (( * A few years ago I decided start the lawn over from scratch, and deliberately killed the whole thing with glyphosate. The new grass is much more vigorous, the old lawn was a 50 year old clone and it showed. )) Glyphosate is extremely effective, and it doesn't take very much. A single light spraying will start to show results in a day or two, and after a week your target will be withered and brown. Glyphosate works by blocking a plant's ability to make food, causing it to starve to death. This works best at moderate temperatures where the plant's metabolism is at its highest, generally in the 70s and low 80s. Outside that range, plants slow down or even go dormant, and results are much slower, tough weeds may even 'sleep off' the herbicide entirely. Also, bulb plants with large underground reserves may need more than one application. Conifers are especially susceptible to herbicides, so be very careful that no mist or overspray gets on them. A tiny bit may not kill a large shrub, but it can kill branches. Glyphosate is also useful for removing problem trees. For example, sweetgum trees will re-sprout from the lateral roots for years after cutting and even stump removal. To get rid of a problem tree like this, you want to kill it first, from top to bottom. To do that, drill a series of 1/2" holes around the periphery of the trunk near the base, angled downward about 45 degrees. Fill them with a fairly concentrated solution of glyphosate and a little dish soap. Refill as needed until the tree dies. Do this in the early fall when the tree is drawing material down from the tops into the roots, so that the roots are killed. When it is dead, then you can cut it down without leaving live roots to re-sprout all over your lawn for years to come. The best and by far most cost-effective way to apply herbicide is to buy the concentrate and mix it up yourself. Much of the cost of the ready-mix is packaging and shipping water. A bottle of concentrate may seem expensive, but do the math - you can save a lot. For application, I recommend a jug-type 2-gallon pump-up sprayer, as these are simple and usually have longer wands that are easier to use. Backpack sprayers are expensive and complicated, and when they leak, they leak all over you. A small trigger-bottle can also be useful, but only for very small jobs. A teaspoon of dish soap added to a gallon of mix will greatly enhance the effectiveness. Oh my, I seem to have said a lot about killing things. But that is what this stuff is for, and it is superb for it. And tree-huggers, fear not - I have planted ten times as many trees as I got rid of. Sniping weeds with a sprayer puts far less herbicide into the environment than carpet-bombing everything, and is far more effective. I find it relaxing to walk around the property for an hour once a month and shoot the weeds. I figure I get about 90% of them every time, by the third time, there's nothing left to do.

Rated 5 out of 5 by from The standard in weed killer The key to this concentrate is value. Roundup is the standard in weed and grass killer and that's because it performs. This stuff works and works quickly. One quick spray and weeds in driveway expansion joints are killed. This stuff also works well along mulch beds to prevent grass from entering and creates a nice uniform line. We also use it for spot sprays in the yard. One thing to consider, when you do spray you need to wait a while before seeding or planting something else. On this concentrate, the amazing thing is it makes 48 gallons! The included measuring cup helps make sure you get the right amount for the job. That's the best value around. Great product at a great value. Good as it gets.

Rated 1 out of 5 by from Disappointing I have always used "Roundup Extended Control" concentrate and have been very satisfied with it's performance, so I expected the same results with "Super Concentrate." I was shocked a few days after using it only to find the weeds and grass that I used it on were still healthy, as if never treated. This is quite unlike the other Roundup product that I've always used and trusted to do the job. Maybe I received a bad batch, but I have to be honest in my review and give accurate feedback. I cannot recommend this Roundup "Purple Super Concentrate."

Rated 1 out of 5 by from Total waste of time and money. Roundup Super Concentrated does not do what its advertised to do! ... Total waste of time and money. Roundup Super Concentrated does not do what its advertised to do! It does not even get the weeds to wilt. It was as though I was spraying water. I called Roundup's customer service line for help and got a lecture that their product doesn't work because of the EPA. They quickly offered to refund but I'd have to mail the receipt to them and wait. More hassle. I spent 3 hours spraying Roundup Super Concentrate and not one leaf has wilted. Don't understand how they can get away with such deception and fraud.

Roundup Weed and Grass killer in concentrated form works great on those hard to kill weeds. My house backs up to a field so I use it back there to keep weeds from creeping in to my lawn. Be careful if you have an incline of any sort. I sprayed weeds on a rocky area and then it rained and the run off killed the good lawn grass. It is best to mix in a tank sprayer. Follow the instructions, it will take 2 to 4 days and thicker weeds may take a couple of applications.

Rated 5 out of 5 by from Great for landscaping work around stone patio and in mulch Roundup is the best for killing weeds and grass for landscaping work. We have landscaping that includes hardscape stones, stone patio with dirt/most in-between stones and mulched areas. It is a bugger to weed everything by hand. I utilize this concentrate along with a 2 gallon sprayer and go out at the start of warm weather (new buds) and again about three-six weeks later. Landscaping then looks great all season long.

Rated 5 out of 5 by from Works great to kill weeds and grass. Round up is an excellent product to use to destroy weeds and any stray grass you may have. I used it to spray my brick paver deck. I used a hose end sprayer and put in the amount as directed on the container. I have a lot of moss and weeds popping up this time of year and after 2 days I began to see the weeds die and the moss turn brown so it works very well and took very little time.

Rated 5 out of 5 by from Big difference in 24 hours I am impressed. I sprayed the weed and grass killer all over the perimeter of the house. The next day the weeds looks like they were dying. In less than 72 hours it became obvious that the weeds were all going to dye off. Within a couple of weeks all weeds were dead and completely brown. Nothing new has popped up, and I would not expect them to. I like how fast this worked.
