Product Overview

RM 18 Fast Acting Weed and Grass Killer Concentrate is a fast-acting herbicide that is absorbed through foliage and begins killing weeds immediately upon contact. This non-selective herbicide can be used to remove unwanted broadleaf weeds, brush, and grass. Ideal for spot treatment as the product deactivates after it reaches the soil, making it safe for non-target plants.  Weeds usually turn yellow and wilt within 12 hours after application and are destroyed in one to two weeks. Works well with tank sprayers and hose-end sprayers. Recommended for use in areas such as patios, walkways, driveways, and fo spot treating in and around flower beds, shrubs, trees, lawns, and gardens.

    RM 18 Weed Killer

    By Eric on 09/22/2023

    Very good product, and a good price. Compared to Round Up, I have decided to use RM 18 fast acting weed killer instead. It works faster, costs less, and it lasts longer.
