Product Label MSDS Sheet

Sonar* Ready-To-Use RTU formulation allows even the most inexperienced pond owner to make water usable for recreation, bring fish populations back into balance and restore property values.

Open the Bottle and Treat

Sonar RTU, the first Sonar product designed specifically for small pond and lake owners. Now you can benefit from time-tested application methods and materials developed by SePRO scientists all in one convenient package you'll use right on your water's edge.

Sonar RTU contains 5% fluridone in an easy-to-use liquid formulation that is applied straight from the bottle. Sonar RTU requires absolutely NO mixing, diluting, spray equipment or boat.

How It Works

Sonar works by stopping photosynthesis, which robs target plants of their ability to make food. Target plants turn white and gradually die over a period of six to twelve weeks. Unlike other aquatic herbicides, Sonar has no restrictions for swimming, fishing, boating or livestock use, even immediately after application. Check the label for irrigation precautions.

Visible effects in 7 to 10 days.

Initial results show a bleaching at growing tips of the weed. Within 7 to 10 days weeds begin to turn white or pink and decay. Under optimum conditions full weed kill occurs in 30 to 90 days. Results occur slowly.

Application

Sonar RTU comes in a distinctive squeeze bottle that only requires the user to lift the nozzle on the lid and squirt the Sonar RTU directly into the water. Treating an entire lake or pond only takes a few minutes. After measuring the size of the water body, consult the rate chart included with each Sonar RTU purchase to determine the amount of Sonar required.

Apply half of the total dose on day one, then return 21 and 42 days later to add the rest. Simply apply Sonar RTU at two to four locations around the water body each time and the unique formulation of Sonar RTU will disperse throughout the water.
