How To Apply

Mix the amount of Ultra Pondweed Defense® and Treatment Booster™ PLUS (if using) with pond water in a tank sprayer according to label instructions. Use a pressurized pond sprayer to spray the Ultra Pondweed Defense® mixture directly onto to the target weeds. Treat only up to half of the pond's surface and wait 10-14 days before a second treatment. In hot weather or when fish are stressed, treat only 1/4 - 1/3 of the pond's surface at a time. For deeper water, place the sprayer's tip beneath the water's surface. Over time, the weeds will begin to brown and die. Once completely dead, use a rake, like the Pond & Beach Rake, to remove dead weeds to prevent an accumulation of dead plant material and muck.

When To Apply

Ultra Pondweed Defense® has no temperature restriction, but it should only be applied when weeds are actively growing. Use with Treatment Booster™ PLUS for best results.

Restrictions

  • Wait 3 days before using treated water for human drinking water.
  • Wait 1 day before using treated water for livestock and domestic animal consumption.
  • Wait 5 days before using treated water for irrigation.
