Roundup Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer Refill, Kills & Prevents for up to 1 Year, 1.25 gal.

I have used Roundup 365 for several years now and love this product for areas that I want to keep weed-free for the entire summer (curbs, patios, etc.) In general, I just spray it down in early Springtime -- and it where ever I've sprayed stays weed-free until the next Spring!I say "in general" because this past Spring I bought a bottle of this from Walmart, spayed it down like usual, and the weeds were back just a few weeks later! I don't know if the batch was bad, or if something had happened during the Walmart distribution process, so I contacted the manufacturer directly to see if they knew of any problems with certain batches of the chemical... They told me there had been no previous complaints about any of the batches, but instantly sent me my money back! It's nice to see a manufacturer who stands behind their products!BTW, please follow the directions on the bottle precisely -- some versions are pre-mixed, but others (like this one) are concentrates that require the addition of water.

I’ve tried multiple brands and always struggled to keep the weeds under control in my rock yard. This product does the trick and lasts much longer than other options I’ve used.

This weed kill is easy to use, just spray and your weeds die. The weed kill works pretty fast, I sprayed yesterday afternoon and within 24 hours it had gotten all the weeds. I like to buy the refill so I can transfer it to my bottle so I don’t have to worry about the sprayer going out. In my opinion this is the best weed kill there is out there. It’s fast, effective and it lasts a long time. I’m not sure about it lasting an entire year but it usually lasts for months which is great.

I bought this for my driveway and in some spots I had to respray so I was kinda disappointed. But whatever e erything I sprayed once or twice is dead. It does have a chemical smell but is not too overwhelming. I hope this stuff will last as it was on the expensive side.

Can’t have enough of this. Smell is a little strong. Kills weeds great. Safe around pets because I have a dog. Coverage is great. Longevity is good

Works as described

Awesome work fast!

Used with Round-Up pump sprayer. Effective, but it seems it washes away, for weeds re-appear in high-flow areas very well in advance of the promised timeframe. Still a good value.
