Parrot’s feather: Use of herbicides - other herbicides
A small, replicated, controlled, laboratory study conducted in the USA (Emerine et al. 2010) found that the herbicide imazamox reduced the growth parrot’s feather Myriophyllum aquaticum. After five weeks, plants treated with imazamox had a dry weight (0.97 g) approximately 40–85% lower than that of untreated plants (3.15 g). Application of imazamox to parrot’s feather regrowth led to similar biomass reduction. Dry weight of plants treated with imazamox did not differ from the dry weight of plants treated with the herbicides glyphosate (0.49 g) or imazapyr (0.39 g). The plants were grown for approximately three weeks prior to herbicide application and each treatment had four replicates. Herbicides were sprayed on plants with no submerged growth. Concentration of imazamox ranged from 35 to 580 g/ha, glyphosate was applied at 2240 g/ha and imazapyr at 560t g/ha.

The plants were grown for approximately three weeks prior to herbicide application and each treatment had four replicates. Herbicides were sprayed on plants with no submersed growth. Herbicide concentration was 560 g/ha for both imazapyr and imazamox and 2240 g/ha for glyphosate.
