- RM18 Fast-Acting Weed & Grass Killer Herbicide, 32-ounce

I used this on ferns, as they were taking over everything. The bottle says that it should kill plants and weeds within 24 hours, but from what I experienced, the plants did not start turning brown till about 24 hours after application, and were not fully dead till about 72 hours, however it did kill grass within 24 hours. I will need to wait till next spring to find out if they are truly dead, or just dead for the season.

Used it two years in a row it knocked my poison Ivy out it started to wilt .With in 24 hours but to me ivy is always hard to kill used dish soap and 6 ounces to a gallon .I'm highly allergic so i re sprayed it this year when it krept back from neighbors yard . it will kill all types weed s in my stone drive way depending on the weed some showed signs right away others with in 24 hours i have thistle clover vine s grass violets etc . Rm 18 is cheaper than round up it almost killed new re emerging weeds from last years dose they had a yellow tint to all there leaves but this year dose knocked them out 12 hours so there must be some left chemical just on drive way want make that clear . when i spray its to kill its heavy .I'm not Melian who loves flowers or weeds i kill every thing i not want or like same when i cut the grass if the husband wants it alive he best cut the grass i kill anything mower can reach .i do not weed whip i use rm 18 no wasting time trimming i have no golf course to run big tractor 6 reel mowers pulling behind

I like the product it was just leaking from the package but it did not leaked that much but other than that is great

I am not sure what some of the bad ratings are about. I bought a 32 oz container to try this product. It arrived on time and was packed well. The plastic bottle was in a sealed plastic bag in case of leaks. Previously I have used a Glyophsate only product that did not work very fast. This product has an additional ingredient.I mixed 6 oz of product in a gallon of water with a few drops of Dawn dish detergent and shook the sprayer well and applied the product to some well-established weeds. 24 hours later the effects were obvious. This did the job for me so I will buy a larger container and if I continue to get these results it will be by go-to non-selective herbicide.

Product is the best. I always use this over any other grass killer. Issue is it comes in and had spilled everywhere. I'll continue to use product but will no longer purchase online

I used this product twice and had no results of killing weeds in my flower beds. I used more than the recommended amount to ensure the weeds were killed but it's not working and weeds are still green and growing. Maybe it's a bad batch from the factory 🤷‍♂️

This was my first time using this weed killer. Worked great and very fast. Has been several weeks now no regrowth. Will use again.

Product takes 3 days to complete kill weeds.Very effective without changing PH of soil like vinegar does. Happy gardner
