When To Use Ultra PondWeed Defense®

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

How To Use Ultra PondWeed Defense®

Mix the desired amount of Ultra PondWeed Defense® and pond water in
accordance to label directions. Using a pressurized sprayer, spray the
Ultra PondWeed Defense® mixture directly onto target weeds. Treated
weeds will begin to brown and die. Once weeds are completely dead, cut
and rake them away to prevent an accumulation of plant decay and pond
