    This stuff will kill, well, pretty much everything if it's plant based.
    J. Tant
    This product is meant to be used for grass and weeds that grow between the cracks in the sidewalk and patio.
    peace
    Some wilting is noticeable within 24 hours, but the weeds don't brown off and die until days later.

    I love this stuff. I use it in a pump sprayer and have been doing so for about 3 years in a row now. It kills EVERYTHING! I spray it along the woodsline to kill poison ivy and keep the line nice and neat. I spray in about mid-may and it keeps anything except moss from growing back for the rest of the summer and fall. For me it has killed poison ivy, many very tall weeds, grass, tree branches (not the whole tree) everything I have ever sprayed that was once green. I also use it in my mulch beds and rock gardens so I don't have to weed around my established plants. It will kill large desirable plants, though, so you have to be careful, but when I have accidentally sprayed desirable plants I just washed then off right away and it didn't do any damage. Works great on driveway seams too. It does not work as quick as the bottle says, though. Usually takes 4 to 5 days for things to get really brown and dead looking. This stuff is kind of expensive but it works and keeps working. Bottle of concentrate makes around 6 gallons. 2 gallons does about 300 feet of woodsline. 1 gallon does the 2 foot rock garden that goes around my whole house. Other/cheaper products I've used including some of that stuff from tractor supply will kill the weeds but they come back after a few weeks. I will keep buying this every year.

    I've been using another well-known product for years but desired to try this one to see if it was any better. Cost wise it was more economical but did not do everything I would have liked. It works very well on grass and weeds (as long as it is not in a wetland area) but does nothing to small saplings or tough plants like blackberries. I suggest adding a small amount of dish-washing liquid to your sprayer because it helps the liquid to stay on the leaves instead of beading off.

    Excellent prduct. I have a very large woodchipped area and a bank around my pond. Other products worked well, but within a week of killing the growth, new growth would begin to appear. This product killed all growth, including vines and pickes and has kept my woodchips and bank area free of any new growth for over a month now. It definitely is "extended weed control". The price on Amazon was the best I could find either locally or on-line. Shipping was fast and very reasonable.

    Size Name: 32-Ounce Verified Purchase
    We live out in the country where weeds and thorny vines really flourish, so I still use either the Roundup Super Concentrate (purple top) or the Tough Brush Killer (yellow top) for much of our more stubborn vegetation such as blackberry vines, multifloral rose, poison ivy, and saplings. It just seems to do a better job of getting rid of the difficult stuff.

    But for sidewalks, flagstone patios and walkways, and driveways, this Roundup Extended Control can't be beat. When I use the purple or yellow topped Roundup on these areas, I end up having to respray every 3-5 weeks to combat all of the new weeds. With the Extended Control, I can usually go 2-3 months before spraying again. The bottle claims that it lasts up to 4 months, but in my experience, it generally wears off before then. Still, it makes a big difference. Instead of the 5-6 times that I would normally need to spray these areas during a growing season, I can usually get by with only spraying a couple times a year.

    Roundup products do take considerably longer to start producing noticeable die-back of weeds. Many weed killers, such as Spectracide Weed And Grass Killer, wilt the weeds within an hour and leave noticeably dead weed "leaves" within 24 hours but have little luck in killing the root. With the Roundup, I rarely notice any effect at all on the weeds until at least a few days later. Even then, it's sometimes up to 2 weeks or more before they are fully dead.

    But, there is a reason for this. Spectracide uses a an active ingredient called "diquat" which kills only the part of the plant that the spray physically touches...

    I originally tried regular Roundup. It killed the weeds that were already growing, but a few weeks later new ones just popped up.

    This extended control formula is a lot more expensive than standard Roundup, but it works great to prevent weeds after the initial treatment. As advertised, I didn't see any weeds for about 3 months. After that, I had to re-apply.

    Some here say there's better products out there, and there may be, but this one works pretty darn well for me. It kills everything I need it to. I just mix it in a pump sprayer and go!

    I gave up buying anything else. I have a pervasive weed and Bermuda grass problem twice every year, southwest desert area. Other sprays have to be reapplied too often and have actually killed shrubs and harmed trees. Not this one! It lasts through to the next spraying time! Do it once and forget bout it! It is very important to apply it in the sun or warmer part of day, but too much sun or heat (in excess of 110 degrees) seem to counteract the effect. Every year I seem to have less to spray, too! So maybe in a few years.........
