Highly Recommended

I am a long time user of Roundup and have achieved good results with each use. It has been very dry in this part of Georgia so the weed population is reduced in size and Roundup reduces it even more and down to zero when applied. Excellent product.

Really Works

This works very fast and does a great job. It's an easy product to use and not too heavy to carry around your yard. The instructions are very clear also. No confusion when using this. My weeds were totally dead within hours. I have used this product for years, but this was the first time I've gotten it in this packaging. I'll buy it again. No mixing, just use it.

Great product and price, it really works great!!!!

Exceeded my expectations. I didn't think this product would completely kill all the grass and weeds especially since I was using it on a fairly descent sized space. Approx 15x10' Within two days everything started to die off. It's been a month and I have not seen any re- growth. See the photos attached. I did not spray my perennial bushes as I want those to come back next season. The precise sprayer helped with this tremendously. I was able to control the flow and spray only where I wanted.

Great for long term relief from weeds and unwanted grass

I mix at a ratio of 6 ounces per gallon. It is expensive but works very well. It is the only weed and grass killer I have found that last fairly long. With less expensive brands I find myself going out 2 weeks after the application and spraying fresh sprouts, I felt like I was always spraying the yard. The cheap stuff seems to kill quickly and have visible results in about 3 hours. This expensive roundup does not show any indication of working until about 2 to 4 days have passed. After 1 week it is looking really bad, 2 weeks and its brown and dead. I use this on my gravel driveway and all around trees so I don’t have to mow or trim near them. When some of this hits a shrub it will kill the part that it hit. I am on a 3 plus acre lot so rinsing the plant is not an option after an accidental spray. With the other sprays I find I am using the spray every 2 to 5 weeks depending on rainfall and weather, this seems to last 2 to 3 months. It is expensive but a great time saver for me so well worth it. This has been a great time saver on my 3 acre yard with several hundred trees and shrubs. I continue to buy this product.

Best formula for weeds

Works better than other formulas because it poisons the root zone too, if you apply enough in the soil area. It lasts about 3 months, if the area gets regular amount of water. More or less depends on amount of water/ rain applied to soil. Can be used on weeds where you plan to replant if you avoid contact with soil and don't work Dead leaves and stems into the soil. Small weeds take a couple of days in warm weather to die off. Larger ones take about a week to turn brown.

Buy it

Fantastic stuff. Weeds are gone. Takes about 3 days to fully kill the weeds it seems but once they're gone - they are gone. Been about a month and no sign of anything. Normally I'd at least see little sprouts appearing but there is nothing growing where I sprayed it. I'd highly recommend this product over the normal Roundup.

Round up, its the best

Roundup works. I tried to save some money earlier this spring and I shouldn't have. It didn't make as much since I couldn't read the full directions on amazon. So I only got half as much with the generic vs round up and it didn't kill the tough weeks. Back to Round UP, I learned my lesson. I am sticking with the good stuff. I sprayed yesterday and can already see brown on everything I sprayed. Still have over half a bottle left after filling a 2 gallon sprayer. Use the best then you know it will work and you don't waste money and time like I did.

A MUST HAVE Spot Treatment For Weeds. Satisfaction Guaranteed

This thing WORKS. There isn't a weed I haven't been able to kill with this thing, it will literally kill everything it touches. Have used it on dandelions especially and will generally work within 24 - 48 hours with just one application. I generally apply once a day for 2 days to make sure it really gets in there and by the fourth day, the weed is generally completely dead. If you are looking for something that is guaranteed to work, this is the product for you.

It is what it says it is!!

I don't understand why buy this stuff in a store anymore, I save at least 20% on everything I buy from Amazon and I get it delivered to the door, I don't even have to spend money in gas going to the store for it, and the time also!! Oh, do you even know what this is? It's for people who live in places like FL like me where weeds try to take over you life! I take it to the extreme and spray all around my house and fence, it works great... this is the Extended control (which means it lasts a long time, which is actually true, it has been proven to me) and the concentrate, you use 6-8oz of this per gallon of water, I have a 2 gallon tank that I then spray all over... I probably go through 8 gallons from spring to fall, don't use in the winter, if you live north of FL you won't need as much... I didn't even know about this nor needed or cared when I lived in NY... For FL it is esential, if you live here you know what I am talking about.

This is the Good Stuff . Works well .

I have used the concentrated or regular round up for years on my driveway cracks to keep grass and weeds from causing more damage then I already have . My drive really needs to be replaced but absent a affordable bid I carry on with what I have . This stuff works well and is priced close to what I can buy it for local . Personally I prefer to buy local but do not get out easy so Amazon won this year . I applied this about a month ago so far so good . Like one person stated moss will grow where you use it without effect but otherwise it does what it says . I am surprised they have another formula for brush and poison ivy . I will be trying that soon as one gets one piece of their property under control they find themselves moving onto the next . I believe for my use this extended week and gas killer plus preventer is definitely the most effective on my drive and sidewalk cracks . I have touched up weekly , I have a rather large drive guestimate about 1800 sq feet definitely larger then most city lots and I figure 32 oz will cover the alligator cracked areas and touch ups for the season . If anyone knows of a rubber process that may keep my drive together shoot me a message under comments . Whoever put my drive in put it in very thin so when it cracked pieces just come loose leaving dirt below . It is only about a inch thick in many areas with alligator cracking over the whole drive . I imagine allot of people who get older or disabled and find themselves neglecting their sealing and also end up with situations like this . You always hear of people being scammed but it seems like a rubber coating could repair it . I asked a hot tar roofer and they said they wouldn't even try coating it . My only bids to remove and replace were over $6 a square foot which I cannot justify as I have been able to get by like this for years . If I could just get a rubber top coat that would hold together over it I think I would be ok . Surprised nobody makes anything other then those hot rubber crack repair machines that leave only a few inch wide repair . It would seem to be affordable to cover the whole drive like that while pressing into the cracks too . Have a great day and this is extended preventer is good stuff where you want weeds and grass killed all season . You may need to still touch up though but will be way ahead over using the regular one time kill stuff .
