Customer Reviews
John Anderson
I’ve used several weed killers in the past, but RM18 is by far the most effective. I had a major problem with crabgrass and poison ivy taking over my backyard. After one application, I noticed results within 24 hours. By the third day, the weeds were completely dead, and they haven’t come back for weeks. The fast-acting formula is perfect, and I love that it works on such a wide variety of plants. Highly recommend it to anyone dealing with stubborn weeds!
Sarah Mitchell
RM18 saved my front yard! Living in a humid area, I constantly battle Kudzu and wild blackberries creeping up my fence. I sprayed RM18 along the fence line, and within a couple of days, I saw a noticeable difference. The weeds turned brown and started to wither away. What I appreciate most is how easy it is to mix and apply. It also didn’t harm the surrounding plants, which was a huge relief. I’ll be keeping a bottle on hand for maintenance!
Robert Carter
As a property manager, I need a reliable herbicide that delivers quick and lasting results. RM18 exceeded my expectations. I used it on a gravel driveway that was overtaken by weeds, and it cleared everything out within days. Even the toughest plants, like poison oak and dandelions, were gone with just one treatment. The best part? No regrowth for weeks! It’s now my go-to product for weed control, and I highly recommend it to anyone looking for a powerful solution.
RM18 FAQ
How long does it take for RM18 to show results?
You will typically see visible wilting and browning within 12 hours of application, though the full systemic kill of the root system can take up to 1 to 2 weeks depending on the weed type.
Is RM18 safe for pets and children?
Once the spray has completely dried on the foliage (usually about 30 minutes to an hour), it is safe for people and pets to enter the treated area.
Can I use RM18 to spot-treat weeds in my lawn?
No, RM18 is a non-selective herbicide, meaning it will kill almost any green plant it touches, including your desirable lawn grass; it is best used for fence lines, driveways, or total lawn renovations.
How soon after spraying can I replant flowers or grass?
Because the formula breaks down upon contact with the soil and does not provide residual control, you can safely replant ornamentals, trees, or sow grass seed one day after application.
Is RM18 rainproof after application?
The formula is designed to be rainfast in as little as 30 minutes, so a sudden downpour shortly after application should not wash away the product or reduce its effectiveness.
What is the correct mix ratio for the concentrate?
For most applications, you should mix 6 fluid ounces of RM18 concentrate per 1 gallon of water to ensure total control of both weeds and grasses.
