Cascade® has revolutionized submerged weed control in irrigation canals throughout the Western United States. Cascade® provides control of sago pondweed, horned pondweed, watermilfoil and other troublesome weeds found in irrigation canals; providing 12-16 weeks of control with a single application. A single injection site can provide weed control for an entire irrigation canal system. At rates of 2-4 ppm injected for 12-24 hours requires only 1.8-3.6 gal. per CFS. Cascade® is easy on the environment and is non-toxic to fish and wildlife when used according to the label.
