Ultra PondWeed Defense is a broad spectrum aquatic herbicide that works on all pondweeds including submerged, floating and emergentweeds. 

Ultra PondWeed Defense may also be used for short-term control of duckweed.

For best results, use on actively growing plants.

Emergent treatments may require additional applications to gain full control. 

For best results, use with Treatment Booster PLUS.

How to Use: 

Mix 16 oz of Ultra PondWeed Defense, 4 oz Treatment

Booster PLUS and 2 gallons of water in a tank sprayer to treat up to

2,500 sq. ft. Spray target directly. 

Only treat up to half of the pond’s surface, wating 10-14 days before treating the second half. In hot weather, or when fish are stressed, treat 1/4 to 1/3 of the pond at a time.

For deeper water, place the tank sprayer’s tip beneath the

water’s surface.
