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.
