Shoreline Defense aquatic herbicide kills a variety of emergent weeds and grasses in ponds. It does not control plants that are mostly or completely below water. The 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 the pond at one time. Following label directions, mix the correct amount of herbicide with pond water in a pressurized sprayer, and spray the mixture directly on the targeted weeds. Avoid getting this broad spectrum herbicide on non-target plants to prevent harming or killing them.
The visual effects of the herbicide appear in 2 to 4 days on most annual weeds and in 7 or more days on most perennial brush plants. Symptoms begin with wilting and yellowing foliage, and continue with browning and deterioration. Once weeds have browned and died, use a rake to remove as much dead material as possible, to prevent accumulation of dead plant material and muck. Note: This herbicide can be reapplied after 14 days.
