May Aquatic Report

Well Spring has sprung and with this seasonal change aquatic vegetation is coming to life.  Some commonly reported problems this spring are Filamentous Algae, Curlyleaf Pondweed and Duckweed and/or Watermeal.  Some identification tips and management options are detailed below:

Filamentous Algae

Filamentous Algae

Are algae cells that form long thread or filament.  Filamentous algae will start to develop in the shallow water around the shoreline of ponds attached to soil, rocks or even aquatic and/or terrestrial plants.  These cellular filaments form mats that float to the surface of the pond.  These floating mats are often referred to as pond scum.

We carry several algaecides.  The liquid products are best to use in controlling the mats that are on the surface of the pond.  While granular formulations are best to use in targeting algae that is still on the bottom substrate of a pond.

Curlyleaf Pondweed

Curlyleaf Pondweed

Is a non-native, invasive plant species.  The identification of this plant can be made by the visual rippled or wavy nature of the leaves along the stem of the plant.  Curlyleaf pondweed is an aggressive plant species that can dominate large areas within ponds and lakes.

We carry several herbicides that will control curlyleaf pondweed.  Aquathol K, Reward, Hydrothol Granular, Weedtrine D and Sonar are some effective herbicides for managing this plant species.  Contact us for help in determining your best option.


Duckweed and Watermeal

Duckweed Watermeal

Duckweed is a green, floating plant.  When collected in a clear container of water a root (or multiple roots in some cases) can be seen extending from each plant or frond.  Duckweed can be aggressive in covering the entire surface of pond and is often found mixed with watermeal.

Watermeal is a very tiny, lighter green floating plant.  Watermeal does not have a root structure and is coarse or gritty to the touch.  It is the smallest flowering plant in the world.

While both of the aquatic plants are small in size, the ability of the plants to reproduce rapidly covering the surface of ponds often leads to fish kills.  Sonar is the best product for elimination of either or both these plant species for a season.  Contact us today for help in determining the proper product formulation and application rate.

If you have other plant species causing issues with your aquatic resource, please feel free to send us pictures for identification and management planning.  We are here to help you enjoy your aquatic resource in the years ahead.
