Pond Logic Shoreline Defense
  • Broad Spectrum Emergent Weed Killer

Kill the roots of even the most persistent emergent aquatic weeds & grasses. Pond Logic® Shoreline Defense® is great for controlling cattails or any other plant growing above or out of the water. Apply directly to the foliage, allowing it to be absorbed by the weed, killing the roots for long term control. Shoreline Defense® is not to be used for submerged weeds. Works great for beaches, shorelines or anywhere emergent weeds grow. Use with Treatment Booster™ PLUS for the best results.

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.

"Killed My Cattails!"Gary of Santee, SC

What a great product! I used Shoreline Defense to kill some new cattail growth, along with the Treatment Booster. Within 3 weeks, the cattails I sprayed were brown and ready to be removed from the pond!
