    • Effective vegetation killer at a reasonable price.
Product works well provided we follow the instructions correctly. For tougher weeds we may need to use more concentrated solution. It did not seem to work for bamboo shoots. Perhaps I may need to apply it several times.

Like most other similar items, it only works on certain weeds.

    • Absolute best flower bed clearer
I can't express enough about this product to be honest. I needed it for a bed clearing job and I didn't want to go through tilling and such although my tiller broke. Anyways I bought this to clear the bed and I did one application. I didn't get back to the property until around a week and a half and when I came today, that bed looked completely done for. There was some monkey grass in there and those roots are tough even though small, like literally out of the total 500sq ft bed there was like 5-6 little clumps of green showing and those can be pulled and that will be cleared out. So hence I did chase the RM18 with some emergent to keep any weeds and such from coming back. so that bed will not have any problems. I used the RM18 on the other side which I didn't till or anything and it killed everything in site. The monkey grass of course although was 97% dead, some green showed so literally all it needs is one more application and it's all done for whatever my customer needs. I used an old hose end bottle I had from other product I used for treatment... so I use that for spraying, just pour the RM-18 that you need in and you can use that hose end to spray and apparently it puts the exactly right amount you need in the mix and good to go. That's my trick. I'm about to purchase more of these bad boys. ... show more

    • Does not work
I bought this for just regular grass kill. It barely yellowed the grass. Did not kill anything. This was applied in dry hot weather and the grass was uncut so it was optimal conditions for it to work if it was going to work as described. I will not buy and would not suggest this product.

    • Works
This weed killer works well. I add it to a spray pump diluted and spray over weeds. As long as there is no rain after using it works effectively and results are seen within a few days.

It's been three and a half hours so far so I will definitely update tomorrow morning and again in a week. But so far feeling super disappointed. There was a guarantee that this product would start to show visible results within hours however if anything my weeds seem to be looking healthier than they did before I sprayed the product. I am only comparing this to the vinegar and soap solution that I used about a month ago which began wilting the weeds within 2 hours and killing them off completely where I had sprayed within 2 weeks. The only reason I decided to use this product is because after research there was a lot of good reports on it that it works and with the vinegar I had to buy at least six bottles and a large bottle of dish soap in order to cover my large yard which has just gone rampant with weeds since I got sick and have not been able to keep up with it like I used to. Now that I'm better and trying to recover myself and my beautiful garden and yard there's a lot of catch up to do. Since this seemed to cover a lot more area with a smaller amount I thought I'd give it a try. Again I will update tomorrow and again in a week but I wanted to show the results at different time periods as I go. Hopefully I will see some results in the next 12 hours. If still no results in a week I will be returning this product unfortunately. ... show more
