BUY This!! OMG No more biweekly or monthly spraying. Thank goodness. Yes, it's considerably more cost but saves your time (a) and (b) it prevents use of double or triple lesser product. Highly Recommend! Review: 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. ## Features - Concentrated mix with water, add to sprayer - Serious Weed Control - Up to one year control - Total Vegetation control ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00CI05VFO | | Active Ingredients | glyphosate | | Best Sellers Rank | #263 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #11 in Weed Killers | | Brand | RM43 | | Brand Name | RM43 | | Coverage | 17297 square feet | | Customer Reviews | 4.6 out of 5 stars 10,643 Reviews | | EU Spare Part Availability Duration | 1 Years | | Global Trade Identification Number | 00737716765007 | | Included Components | RM43 43-Percent Glyphosate Plus Weed Preventer Total Vegetation Control, 1-Gallo | | Item Form | Spray | | Item Type Name | RM43 43-Percent Glyphosate Plus Weed Preventer Total Vegetation Control, 1-Gallo | | Item Weight | 9.4 Pounds | | Liquid Volume | 1 Gallons | | Manufacturer | RM43 | | Model Number | 76500 | | Part Number | 76500 | | UPC | 737716765007 | | Unit Count | 128.0 Fluid Ounces | | Warranty Description | Warranty | ## Product Details - **Active Ingredients:** glyphosate - **Brand:** RM43 - **Item Form:** Spray - **Item Weight:** 9.4 Pounds - **Liquid Volume:** 1 Gallons ## Images ![Concentrated Extended Control Weed Killer - Image 1](https://m.media-amazon.com/images/I/81I87Eqy4hL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: how much water do mix per ounce of weed killer** A: six oz. to one gal.RM43 43% Glyphosate Plus Weed Preventer Total Vegetation Control is ideal for fence rows, gravel paths, sidewalks, driveways, parking areas and around farm buildings and barns -- anywhere you want to spray once and be done for up to 1 year. The concentrated formula of glyphosate and imazapyr is effective against most noxious weeds, grasses, vines, brush and trees. For use on non-crop areas as a spot treatment for brush, vines and weeds or on bare ground for total vegetation control. Do not spray this product over the root systems of desirable plants. One gallon treats 17,297 square feet. **Q: My front yard is bad with weeds, I want to spay this on the lawn the till the yard, then plant new grass seed. Will new grass seed work in the soil?** A: This weed killer also has a seed germination preventer that last about a year. I would not recommend RM43 for your weeds. Round-up is what you should use. **Q: How many sq feet does a mixture of rm 43 mixed 6 - 7 oz per gal treat for. good kill?** A: Ok there are two rates on the label. One is 6 ounces per gallon for spot treatments and the other is confusing and is more for spraying large areas. It says to use 7.4 ounces in 1 to 10 gallons of water and to spray that over 1000 square feet. Basically what that means is use whatever water between 1-10 gallons that it takes you to cover 1000 square feet at the pace you are working and the rate your sprayer is putting out spray. What is important is that you get 7.4 ounces of chemical over 1000 square feet. Call us at 800-264-5281 if you have any questions. **Q: How long until you can see results?** A: I was a little nervous when I first mixed up a batch and sprayed weeds. It honestly takes three to five days to see results. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly Recommend! *by B***Y on June 19, 2026* IF you want the gtass and weeds where you are spraying to die and not regrow a week later...

I am a 76 year old man with bad back and knees, I have a 4 acres of yard to take care of and if you are like me no matter your age that weedeater will kill your back.I have been using RM43 for many years and this product saves me a lot of work and pain.I have a 4 gallon backpack sprayer, I use 8 Oz of RM43 per gallon and I also add 6oz of 2-4D as a carrier and I weedeat everything one good time and then I spray all my fince lines, under my pool deck everywhere I have to weedeat , I spray on a very sunny day high heat also helps increase the time to kill Usually the next day everything is dead,and I only spray just 1 time a year. This product RM43 is worth every penny.As I said I'm 76 years old and every step I save not having to use that weedeater is worth it. ## Frequently Bought Together - RM43 Concentrated Extended Control Weed Killer - Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White - RM18 Fast-Acting Weed & Grass Killer Herbicide, Spray, 1-gallon --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/11011020-concentrated-extended-control-weed-killer](https://www.desertcart.ni/products/11011020-concentrated-extended-control-weed-killer) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-07-10*
