How To Apply

Mix the amount of Shoreline Defense® and Treatment Booster Plus (if using) with pond water in a tank sprayer according to label instructions. Spray only on foliage above the water's surface on a calm day to keep sprayed contained to target areas. Completely wet foliage for best results. Over time, the weeds will begin to brown and die. Once completely dead, use a rake, like the Pond & Beach Rake, to remove dead weeds to prevent an accumulation of dead plant material and muck.

When To Use

Shoreline Defense® has no temperature restriction, but it should only be applied when weeds are actively growing. Use with Treatment Booster Plus for best results.



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 cattails or emergent 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
