Myriophyllum aquaticum - parrot-feather
|
Aquatic perennial,
that in addition to affecting water bodies associated with agriculture,
parrot's feather also takes over lakes and rivers, and crowds out
native vegetation, degrading fish and wildlife habitat. To control
parrot's feather, harvesting just before peak plant biomass and removal
of plant fragments is recommended. This will allow the water body to be
used recreationally, but it will have to be repeated at least yearly
and it will not eradicate the plant. It is also advised that
recreational water users be alerted to the presence of the plant and
the means by which it is spread. At present, the most effective method
of eradication is via herbicide. Because parrot's feather has a waxy
cuticle on its stems and leaves, it is important to follow directions
specific for this plant. Also, recreational use of the lake should be
prohibited, because fragments can spread the problem. Biological
control looks promising, but further research needs to be conducted.
