Plant Identification -- Submerged Weeds -- Brazillian Elodea |
BRAZILIAN ELODEA (Egeria densa)
Treatment Tips: Care should be taken to remove weed fragments from equipment, boats and trailers since infestation of new areas can occur by human transportation.
Description: Plants are very similar to Hydrilla but the leaves are not toothed.A visual inspection and handling of the leaves will quickly distinguish it fromHydrilla. Both species are controlled with similar treatment.
Distribution: California, Arizona, Gulf states and southeastern states north to Washington, D.C.

Recommended Control Method: Tank mix 3 1/3 gallons of Cutrine-Plus with 2 gallons of Reward and inject below the surface. For soft water, reduce Cutrine-Plus to 2 gallons. Above recommendations will treat 1 acre.
OR
Apply Clearigate at the rate of 3.6 to 8.7 gallons per acre-foot for Hydrilla or 5.4 to 8.7 gallons per acre-foot for Brazilian Elodea.
OR
Apply Cutrine-Plus at the rate of 1.2 to 3.0 gallons per acre-foot in areas where water use restrictions are prohibitive.
OR
Tank mix 5 parts Aquathol K to 3 parts Cutrine-Plus and apply at the rate of 2 gallons per acre-foot.
|
Maintenance Control Method: Add Aquashade at the rate of 1 quart per acre-foot of water to prevent initial growth or to retard regrowth of plants after chemical treatment.
