Control Duckweed

Duckweed has the ability to multiply rapidly and can infest a pond or quiet bay in a matter of days. Duckweed can be a major nuisance for homeowners due to its ability to turn an otherwise beautiful pond into an unsightly mess. Luckily, controlling duckweed in ponds is very simple. We recommend our Dibrox® Herbicide – it is easy to use and will eliminate duckweed from your pond. See our POND solutions to determine what products are suited for your pond.

Duckweed is commonly spread by migratory birds flying between ponds with the tiny plants clinging to their feathers. Duckweed is very prolific, and given enough nitrogen and phosphorus nutrients, it is possible for a new duckweed plant to be produced every 24 hours. This means that in just two weeks, a single parent plant can result in up to 17,500 plants!

Extensive mats of duckweed colonies may cover an entire pond surface, depleting oxygen and blocking sunlight. Fish and submerged plants can be killed. Because of this, duckweed infestation often contributes to poor pond health.

Duckweed can tolerate a wide range pH, between 4.5 and 7.5, as well as temperatures between 68F (20C) and 86F (30C), making duckweed a challenging aquatic plant management issue worldwide.

For effective duckweed control and removal at a reasonable cost (and without environmental damage or risk to water users), choose which POND Solution products you need to give you control over your duckweed.

Diquat herbicide is also an effective short-term duckweed killer if used repeatedly. We recommend using our Dibrox® Herbicide which contains the same active ingredient as Diquat.
