Ultra PondWeed Defense® should be applied to target weeds while they are active and growing. Use with Treatment Booster™ PLUS for best results.

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.
