Product should be applied as close to Myriophyllum spp. Underwater Najas spp. Do not disturb with motor wake or paddles after treatment. Choose a dilution which will allow relatively even application throughout the intended treatment area with the type of equipment being used. Prior to treatment, it is important to accurately determine water flow rates.
Velocity is the time it takes a floating object to travel a given distance.
Repeat measurement at least 3 times at the intended application site and use the average of these measurements. If turnover time is less than 3 hrs., substitute 3 hrs. into this calculation. Calibrate drip system, metering pump or similar dosage device to establish output rate determined in Step No. 9. This can be done using a watch with a second hand and a calibrated measuring cup, graduated cylinder or similar vessel. Turn them on as simultaneously as possible, beginning with the device furthest upstream.
