Parrot’s feather: Use of lightproof barriers
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
Covering submerged weeds with lightproof barriers, such as plastic foils, tarpaulins or black sheeting, can control growth and eventually kill plants by preventing photosynthesis (De Winton et al. 2013). Lightproof barriers have been used to control other species of the same genus of parrot’s feather with some success (Eurasian watermilfoil Myriophyllum spicatum) (Laitala et al. 2012). The method is not species-specific and its usage is usually restricted to small-scale management in slow-flowing or static waterbodies (Hussner et al. 2017).
