The aquatic weed Parrotfeather is a rooted weed that generally grown in shallow subsurface areas throughout the United States and many other countries. The plant gets its name from due to its appearance which is usually similar to bunches of leaves that become emergent as the plant matures. The emergent portion of the plant swirls and groups to form a dense mat, thus the name Parrotfeather.
The plants are not entirely detrimental to the pond provided growth is not excessive. Letting parrotfeather flourish unattended for years can result in virtually all areas of the pond being completely covered. As the old growth dies down, it begins to decompose which provides nutirents for the aquatic life within the water. Exorbitant amounts of decomposition can lead to oxygen depletion and can have a negative impact on the ponds entire ecosystem.
As Parrotfeather left untamed can become a true nuisance weed, growth control is always preferred since the weed is invasive and there are many alternate, less all consuming, options to add to your aquatic foray.
Clipper herbicide containing flumioxazin is an excellent choice when dealing with excess Parotfeather infestation. Clipper is a fast acting contact control product that will eradicate all target weeds when applied per labeling. It is best to apply Clipper early in the day and quickly after tank mixing the spray solution. Light blocking aquatic dye’s such as Aquashade can help control growth prior to a Clipper application. Follow all directions on container labels to assure maximum blockage.
