RM43 Concentrated Extended Control Weed Killer

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. 👍🌱

I mixed 6oz of RM43 weed killer with one gallon water sprayer and sprayed three gallons in ditch three days ago and it took about a week and half and it did do job of getting rid of all weeds. Also with other weed killer when we received a major rain which filled the ditch, weeds would come back. Now it been close to month and all weed are still gone. It took longer to work but so far I’m very pleased with RM43.

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.

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.

I have finally stayed away from Round UP and sold on RM43. It's very effective killing weeds along the roadside but you have to be patient in its effectiveness. It doesn't kill right away but it brings slow death to all kinds of weeds it touches. I was truly impressed since I have tried literally every brand of weed killer at the store but this RM43 is by far the most effective weed killer for your home. Simply follow directions and I used a spray container to treat the weeds. I made sure there was no forecast of rain before application. Also be sure not apply it during windy days to avoid contaminating your good plants in the garden per se.

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.

RM43 really works. Careful because it kills all vegetation. Takes 2 weeks to see full results.

Great weed & Grass killer. Good value compared to shopping locally.
