How To Apply
Apply Sonar™ RTU directly into the water either in one location or multiple locations and Sonar™ RTU will mix throughout the pond. Sonar™ RTU should be applied with an initial application followed by two additional applications at three-week intervals. Over time, the weeds will begin to brown and die. Once completely dead, use a rake, like the Pond Logic® Pond & Beach Rake, to remove dead weeds to prevent an accumulation of dead plant material and muck.
When To Apply
Apply Sonar™ RTU during sunny, dry, non-windy conditions. Best results are typically achieved by starting applications just as weeds have started to grow.
Restrictions
- Wait 30 days after final treatment before using treated water for irrigation.
