This efficient and economical EPA registered product kills all unwanted and injurious weeds and grass, non-selectively, without sterilizing the soil. As a "top killer," it only kills above-ground, green plant material as well as aquatic weeds. Deactivates upon contact with soil on trees and other woody stems.  Ideal for areas where ornamental plants are present. Dilution is 16 oz. to 1 gallon of water.
