TextPublication details: Madison, WI : 1992. University of Wisconsin,Description: 11 p. : ill. ; 28 cmOnline resources: Abstract: Purple loosestrife (Lythrum salicaria L.) is an aggressive invader of North American wetlands that has been resistant to previous control methods. The lack of success with control methods may be the result of an inadequate application period in the case of herbicide use, or application of control method at a sub-optimal time in the case of previous cutting methods. While cutting loosestrife stems was tried in the past, it was always tried during the summer. Beule (1979) showed that cattails could be controlled by cutting of stems at the end of the growing season, followed by flooding over winter. The results of this experiment showed that purple loosestrife stems and biomass were significantly decreased by similar procedures.
