How To Apply

Broadcast Navigate onto the area to be treated using a granular spreader. Treat only up to half of the pond's surface and wait 21 days before a second treatment. In hot weather or when fish are stressed, treat only 1/4 - 1/3 of the pond at a time. Over time, the weeds will begin to brown and die. Once it is completely dead, use a rake, like the Pond & Beach Rake, to remove the dead weeds away to prevent an accumulation of dead plant material and muck.

When To Apply

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


  • Wait 24 hours before swimming in treated water.
  • 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.
