Item Information

Ultra PondWeed Defense is a broad spectrum aquatic herbicide that works on all pondweeds including submerged, floating and emergent weeds. Pond Logic Ultra PondWeed Defense may be used for short term control of duckweed. For best results, use with Treatment Booster PLUS when weeds are actively growing. Ultra PondWeed Defense should be applied to target weeds while they are active and growing. Use with Treatment Booster PLUS for best results. 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 muck. For best results, use Ultra PondWeed Defense with Treatment Booster PLUS.

Is it safe for family pets to drink, swim, etc?

Asked by: burbee
This is safe for family pets, however you will need to wait 1 day before using treated water for livestock and domestic animal consumption.

can this product be used in fishing ponds

Asked by: bear 65
This can be used in fishing ponds. However, in this case, you should only treat about 1/4 to 1/3 of your pond at a time to assure you don't deplete all the oxygen in the water for the fish. Treatments should be spaced about 10 - 14 days apart.
