When To Use PondWeed Defense®

PondWeed Defense® should be applied to target weeds while they are active and growing. The active ingredients in PondWeed Defense® will be absorbed by the plant where it travels to the roots killing the entire plant.

How To Use PondWeed Defense®

Mix the desired amount of PondWeed Defense® and pond water in accordance to label directions. Using a pressurized sprayer, like our Airmax® Specialty Tank Sprayer, spray the PondWeed Defense® mixture directly onto target weeds. Once treated weeds are completely dead, cut and rake them away to prevent an accumulation of plant decay and pond muck.
