Review: The best weed killer and PREVENTER you can buy - This is yet another product where people around me can't understand why I pay $80+ a gallon for weed killer when you can just go to Home Depot and buy whatever they have there. It does the same thing right? No, not really. This stuff works the first time around, and knocks everything down to the dirt. Results don't happen overnight, but it is worth the wait as this product works into the roots of weeds and undesired plants to kill them, which eliminates them at the source. Most "store bought" weed killers don't attack the roots so they just grow back over time, usually stronger with a tolerance to whatever weed killer you just used - therefore starting a vicious cycle. RM43 also has a pre-emergent built in which will prevent new growth of weeds (or grass) for up to a year - this prevents you from having to go back and spray the same areas multiple times throughout the year. IMPORTANT: if you accidentally spray a section of your lawn or have some of this seep into it, you will not be able to plant and successfully grow new grass there right away. Be very careful using this product. It'll probably be at least a year until you can fill in those bare spots with grass. For best results I mix this at around 6/7 ounces per gallon of water, going slightly stronger for heavily overgrown areas and for our gravel driveway. I like to mix in a couple ounces of their 'fast acting' RM18 as well, which will give you visible results in about a day or two. It doesn't contain the pre-emergent, and isn't as strong, but it feels like it speeds the process up a little bit. Because of this product we maintain a weed-free 500ft gravel driveway and other common areas such as beside our in-ground pool (landscaping rock around it) and our rock covered firepit. Also around our pole barn. These areas quickly get weed infested without taking action. People comment on our lack of weeds and ask what we use, but of course are always repulsed at the price. You decide what your time is worth. For me, $80 a gallon is well spent knowing I only have to spray for weeds once, or maybe twice a year.
Review: Love it!!!! - You don’t have to use much at all! A little goes a long way!!!! :) for the money you’re spending it is worth it!!!! We put maybe 6 cap fulls and put the rest with water in a 10 gallon jug sprayer and it worked for my huge backyard and we have a 3rd of an acre. I would honestly spray the dirt first to prevent the weeds from coming up at all :) kills the weeds fast and it keeps the weeds from coming up for a few weeks maybe even months depends on how much you spray in the spot. Works great!!!!

## 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.

### ⭐⭐⭐⭐⭐ Works better than any other brand or type I have tried! Will buy again and again...
*by G***S on August 18, 2025*

GREAT PRODUCT! This is the best weed killer I have ever used! It not only kills the weeds in about 7 days but it kills them down to the ground, they are just completely dead and basically dissolved. It also has worked great as a weed preventer... after 3 months I still have no weeds growing in my driveway, I was up to 4 bags of another popular brand grainules that was supposed tom last for 4 - 6 months and was having to retreat 3 to 4 time a year and still could not stop the weeds from growing. This definately my new go to replacing to different tratment types, a spray weed killer and a preveter granuals.
