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 ### ⭐⭐⭐⭐⭐ Save your back and time young or old.This Stuff is Amazing *by R***M on March 27, 2026* This stuff is a back saver.
