This RM43 saves me lots of time. Highly recommend.
I get faster dieback using Spectracide or Roundup, but weeds sprayed with RM43 stay dead, where the spectracide and roundup weeds are back within 2 weeks. I really appreciate having to spend less time spraying weeds. It hasn't been a year, so I don't know how long this herbicide will actually last, but it has been 3 months on sections I sprayed first, and so far they haven't come back. I even had a section of nutsedge die from this. I've been fighting that nutsedge for a decade, and nothing fazed it, until I sprayed RM43 on it. I like the fact this product is red, because I can see that the mixture is evenly mixed before spraying. It's pricey, but if I only need to spray this once or twice a year, instead of monthly, it ends up being much cheaper, and a huge timesaver.

works great, just not fast.
Was concerned at first, didn't show any signs of really working, but after a week, everything was dying. 9 days, it's all dead, great, just not fast.

Amazing Results Around Our Fence Line
This stuff is amazing! I sprayed it along the base of our fence line to eliminate the need for constant weed eating, and it has worked exactly as I hoped. The weeds and grass died off, leaving a clean edge along the fence that's much easier to maintain. It's going to save me a lot of time and effort throughout the growing season. The concentrate mixes easily, and a little goes a long way, making it a good value for larger properties. Overall, I'm extremely happy with the results. If you're looking for a product to help keep fence lines and other hard-to-maintain areas free of weeds, this one definitely gets the job done. 👍🌱

Great for a wooded parcel
I have been using this for years on my property. I have a wooded parcel that had some mulching done on it and this stuff will kill any new seedlings that come up. Spay every year for 2 or 3 years and it will prevent new seedlings from coming up over time. Be patient because it takes a little time for it to work.

It does work, just takes a very long time!!
This stuff does work but it takes over 2 1/2 weeks to kill the weeds!! WOW, a really long time, thus the 3 star rating instead of 4. Also, I more than doubled the amount to use because I had such tall weeds that needed gone. Not sure how good it would work using the recommended amount or how long it would take to kill the weeds. Because it does take so long to do anything. At at least it finally did work.

5 days to clear
Attached photos from day one to day five. I used 6oz to one gallon of water in a pump sprayer. This product is expensive. It also works. I’ve tried other products for the same application. The grass grew better between my stone than it did in the lawn. The weeds are crispy but still present on day 5. I can sweep them and they fall to dust. This definitely works.

Wow!
This stuff really works! If you are tired to constantly using round up this is a one time application that will save you hours. We have many areas around our rural home where the weeks love to grow and take over. Paths, along outbuildings, gravel drives, all over the place. One application and these unsightly, fast growing nuisance plants are no more. Give it a week and bye, bye weeds! Till next year anyway. Make sure you have pants and boots on, can’t be too good to get overspray on you. And no doubt it’s knocked down habitat for mice and ticks and chiggers also. Win win!
