Purple Loosestrife
Lythrum salicaria
Introduction
Purple loosestrife (Lythrum salicaria) is an introduced plant
originally from Eurasia and Africa. It was brought over because of
its ornamental value. It is a beautiful plant with purple blossoms.
It has now escaped into the wild and is very difficult to control.
Environmental Impacts
Purple loosestrife destroys wetlands by literally shading out
any natural vegetation. It grows vigorously near Nebraska waterways
and destroys many animal habitats as well. Thick infestations of
purple loosestrife will reduce the number of birds in the area and muskrats
will no longer have a habitat. On January 1, 2001 purple loosestrife
officially became a noxious weed in Nebraska.
Remedial Action
What is being done to control this weed? There are some
herbicides that can control purple loosestrife. Roundup and 2,4-D
will work but since purple loosestrife grows in close proximity to water
extra care must be taken when using herbicides. Another more long-term
option is to use biological controls. Some insects that feed on purple
loosestrife have been introduced to Nebraska and it will take time to see
if they will be successful in controlling purple loosestrife.
