Plant Description

Baby pondweed is a perennial plant that arises from thickly matted rhizomes and has no floating leaves. The stems are thin, long and highly branching with leaves very thin and filament-like, about 1/16 of an inch wide and 2 to over 12 inches long tapering to a point. The leaves grow in thick layers and originate from a sheath. The fruit is nut-like 1/8 to 1/4 inches long and 1/10 to 1/8 inches wide.

Common Application Questions

Q. What are the best control options?

A. Herbicide Application:
Hydrothol 191 Granular or Aquathol Super K granular are very good control agents.

Q. When is the best time to treat?

A. Once water temperatures are around sixty degrees or warmer and the plants are viable.

Q. How often do I need to treat?

A. Generally, there is little regrowth within the same season. Note that some aquatic species like the Naiad family grow later in the season that may require a mid to later season treatment to achieve season long clear water.

Q. How long before I see results?

A. Generally within two weeks things will be cleared up.
