Plant Identification -- Submerged Weeds -- Leafy Pondweed |
LEAFY PONDWEED (Potamogeton foliosus)
Treatment Tips: Treat these plants before seeds appear. This may not only prevent a regrowth later in the season, but may reduce these weed populations in subsequent years. In waterfowl areas, these plants are a valuable food source.
Description: Short, grass-like submersed leaves. Clumps of 4 to 8 fruiting bodies are attached to a center stem by a short seed stalk. Grows from shallow water to a depth of 4 feet.
Distribution: Occur throughout the United States in highly variable forms based on local conditions.
|
Recommended Control Method: Tank mix 1 part Cutrine-Plus to 2 parts Aquathol® K. Apply at the rate of 1 gallon per acre-foot of water. Dilute to facilitate even distribution.
|
Maintenance Control Method: Add Aquashade at the rate of 1 quartper acre-foot of water to prevent initial growth or to retard regrowth of plants after chemical treatment.
|
Alternate Control Methods: Aquathol® Granular: 27 to 81 pounds per acre-foot.
Aquathol K liquid: 0.6 to 1.9 gallons per acre-foot.
Clearigate: 4.4 to 8.7 gallons per acre-foot.
Cutrine-Plus/Reward: Tank mix in the ratio of 1:1. Apply 2 gallons per surface acre.
Reward: 2 gallons per surface acre.
Fluridone: Various liquid or pelletized formulations (see label).
*Nutlets: a small nut or nut-like fruit.
