Landoltia punctata (L. punctata) , the most investigated representative of the Landoltia genus, showed high phytoremediation capacities along with … Chemical: Diquat is a widely used and effective herbicide because it causes ion leakage in duckweed and other aquatic plants.A Florida study showed that after 20-30 years, Landoltia punctata developed resistance to Diquat and Paraquat herbicides. Currently, there are several studies suggesting the capacity of these plants for the removal of organic contaminants such as petroleum hydrocarbons and transforming or sequestering them in nonphytotoxic forms (Macek et al., 2000). Tomás López Arias Landoltia punctata invades quiet waters such as ponds, ditches, swamps and backwaters. Landoltia punctata has been considered as a potential bioenergy crop due to its high biomass and starch yields in different cultivations.
