When is the best time to treat with SonarOne?

It is best to apply SonarOne early in the season when aquatic weeds begin growth. 

Can I use Sonar One to spot treat weeds growing in my pond?

No, Sonar One is a whole pond treatment. This should be applied throughout the entire body of water.

How does Sonar work?

The active ingredient in Sonar is fluridone. After the Sonar is broadcasted across the pond's surface, it spreads throughout the whole water body. Sonar is absorbed through the plant shoots. Once absorbed into the plant, it stops the formation of carotene, which is needed to transmit energy absorbed from chlorophyll. In the absence of carotene, plants begin to turn white. Begin noticing results in 15-30 days. Complete management of weed species in 30-90 days.

Aquatic Weed Treatment Instructions:

Broadcast pellets over pond surface. Pond should have very little flow through for at least 30 days so that the treatment is not dilluted.
