Identify the weeds to be controlled – There are many resources including the Internet. Note how the leaves are arranged on the stems, the fruiting bodies (if there are any), and if it is rooted and stays submerged, or if it is rooted with emergent growth.
Aquatic growth falls into different categories and helps to define the type of weed and how to treat that weed.
Algae: String algae, planktonic and a rooted algae like chara. Resistant strains of algae such as Pithophora and Lyngbya.
Treatment method: Difficult strains of algae can be attacked by tank mixing 1 part Pond2O Submerge Weed Control (diquat) with 1 part Pond2O Algae Treatment (liquid copper w/stabitrol) and applying at the rate of 2 gallons of mix in sufficient water to cover 1 acre, 1 foot deep – or 1 acre/foot.
Floating Plants: Duckweed, Water meal, Water Hyacinth, Yellow & White Water Lilly and Watershield.
Submerged : rooted weeds: Pond weed- several varieties including Sago, American and Curley leaf, Eurasian water milfoil, Star grass, Naiad, Hydrilla and Elodea to name a few.
Submerged – Non rooted: Coontail is a submersed plant without roots.
Emergent/Shoreline Weeds: Cattails, Spike and Bull Rush, Purple loosestrife, Water primrose, Knotweed, Arrowhead and Water willow.
Timing is important to get good results with any method of treatment that is used. Young actively growing plants will respond much better to herbicide treatments than older well established weed problems.
