When To Apply

Navigate® should be applied when weeds are actively growing in early spring and summer. Begin applications when weeds first appear.

  • Wait 21 days before using treated water for human drinking water.
  • Wait 21 days before using treated water for irrigation on forage or food crops.

Chemical Application Best Practices

Anytime you use chemicals to treat algae or weeds, please keep in mind the following:

  • Treat your pond in sections. Treat only half the pond's surface at a time. During hot weather or when treating heavy growth, it is important to treat no more than ¼ of your pond at a time and wait the full 14 days before re-applying. This helps lower the risk of fish loss during hot weather or when treating heavy growth.
  • Once the algae or weeds have browned & died, use a rake to remove as much dead material as possible. This prevents an accumulation of dead plant material and muck.
  • Take a proactive approach to pond management. Use PondClear, MuckAway and Pond Dye to keep your pond looking great. For more information, see our article on the Airmax® Ecosystem
