Pond Logic Shoreline Defense 1 qt 32 oz

Pond Logic Shoreline Defense aquatic herbicide kills a variety of pond weeds. It does not control plants that are mostly or completely below water. Its active ingredient is glyphosate. Dying plants reduce the oxygen level in water which can endanger fish. So apply Shoreline Defense to only 1/4 of a pond at one time. Following label directions mix the desired amount of this herbicide with pond water in a pressurized sprayer and spray the mixture directly on target weeds. Avoid getting this broad spectrum herbicide on non-target plants to prevent harming or killing them. The visual effects of this herbicide appear in 2 to 4 days for most annual weeds and in 7 or more days for most perennial brush plants. They begin with plants wilting and yellowing and continue to browning and deterioration. This herbicide can be reapplied after 14 days.
