When you want fast results with minimal prep, the 64 oz. RM18 Fast-Acting Grass and Weed Killer with Diquat is your total solution for unwanted brush, grass and broadleaf weed control. Perfect for lawn replacement, clearing walkways, and leveling weeds along fence lines, buildings, and roadsides, this weed killer for grass kills the weeds while leaving fertile soil available for the plants you want-any product not absorbed by the plant will deactivate after it touches the ground.

10 months ago1 Answer

Diquat and glyphosate are both herbicides, but they work in very different ways. Diquat is a contact herbicide that breaks down quickly in the environment and does not persist in soil. We offer products with clear labeling and usage instructions to ensure they are applied safely and responsibly. If you’re looking for alternatives or have specific concerns, we’d be happy to help you choose the right product for your needs.10 months agoHelpful?

Wicked Stuff - NOT Fast!
2 years ago
I've now used the RM-18 in two different applications, and I have found it to be *extremely* effective, it kills everything you spray it on, without any ifs, ands, or buts. HOWEVER! It is *not* as fast as they say it is. In the first three days, I saw absolutely nothing happen, or only maybe the very slightest bit of graying on the edges. By the end of the first week, the sprayed area was looking very distressed and much of it was visibly dying or dead. By the end of the second week, absolutely everything in the sprayed zone was stone dead.
For reference, I used a mix of 4.5oz per gallon of water, along with 3ml/gal of an indicator dye to make sure I got good coverage of all areas, and sprayed at about 1pm on a warm, sunny day for maximum impact.
So this stuff does work, and it works very well! Just be patient, and the weeds will die off just fine.

Took days for minimal results. Grass and small weeds are barely browning. Large weeds are unaffected. Will still have to make or buy something that works. Waste of time and money.

Does great if you mix less water
a month ago
This product was recommended by a friend. I found it more effective not following the directions on the label. When you follow their mix, it does not work as fast killing weeds. One day after application, you're ready to pull the weeds.
Yes, I recommend this product.

Great Weedkiller

This is the best weedkiller we have found and it does not smell. Weeds are yellow the next day. It doesn't seem to work as well as it did 2 years ago though.
