Cascade Aquatic Herbicide, UPI

Cascade Aquatic Herbicide for aquatic plant control in irrigation systems and other flowing water sites and quiescent, or slow moving waters 

Cascade Aquatic Herbicide 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. 

The majority of applications will target the aquatic weed sago pondweed. The rates needed for sago pondweed control are approximately 1.25 gallons of Cascade per cubic foot per second (CFS), which is directly tied to UPI’s rule of 24.

Hours of Application Concentration in Parts Per Million
24 hrs. 1 PPM
12 hrs. 2 PPM
8 hrs. 3 PPM
6 hrs. 4 PPM

If targeting an aquatic weed other than sago pondweed, please see the Cascade label for recommended rates and length of application.
