Wetlands in the Prairie Pothole Region of North America are integrated with farmland and contain mixtures herbicide contaminants. Passive nonfacilitated diffusion is how most herbicides can move across plant membranes, making this perhaps an important process by which contaminants absorbed wetland vegetation. wetlands dominated native cattail (Typha latifolia) hybrid x glauca). The objective batch equilibrium study was to compare glyphosate absorption shoots rhizomes versus cattails. Although it has been previously reported for some pesticides that passive greater rhizome than shoot components, first demonstrate capacity species dependent, being significantly case cattails, but no significant differences between Most importantly, far exceeded occurring rhizomes, shoots. Glyphosate long used manage invasive cattails America, expansions continue occur. Since our results showed limited lack sorption may partially explain poorer ability control wetlands.
