Parrot’s feather: Use of herbicides - diquat
A small, replicated, randomized, controlled, laboratory study conducted in 2006 in the USA (Wersal et al. 2010), found that the application of the herbicide diquat reduced growth of parrot’s feather Myriophyllum aquaticum. After four weeks, the dry weight of parrot’s feather plants treated with diquat was lower than untreated plants (1–3 vs 6 g/pot). Daytime and night-time application of the herbicide resulted in similar results. Parrot’s feather shoots were propagated in 3.78 l pots and placed inside 246 l containers filled with water. Each herbicide rate (0.19 and 0.37 mg/l) was applied to three plants.

Parrot’s feather: Use of herbicides - carfentrazone-ethyl
A small, replicated, randomized, controlled, laboratory study conducted in 2006 in the USA (Wersal et al. 2010), found that the application of the herbicide carfentrazone-ethyl reduced growth in parrot’s feather Myriophyllum aquaticum. After four weeks, the dry weight of parrot’s feather plants treated with carfentrazone-ethyl was lower than untreated plants (1–2.1 vs 4.6 g/pot). Daytime and night-time application of the herbicide resulted in similar results. Parrot’s feather shoots were propagated in 3.78 l pots and placed inside 246 l containers filled with water. Each herbicide rate (0.1 and 0.2 mg/l) was applied to three plants.
