Parrot’s feather: Use of herbicides - 2,4-D
A small, replicated, controlled, laboratory study conducted in Brazil (Souza et al. 2012), found that the application of the herbicide 2,4-D reduced plant growth in parrot’s feather Myriophyllum aquaticum even when plants were exposed to simulated rainfall. Seven days after the application of 2,4-D at concentrations of 670 g/ha and 1340 g/ha, treated parrot’s feather plants were controlled by 61.5% and 81.5% respectively, when exposed to simulated rain 15 minutes after herbicide application. Exposure to simulated rain only influenced treatment if it occurred within 15 minutes of herbicide application and for a 2,4-D concentration of 670 g/ha. With or without simulated rain, the control was almost complete 21 days after the application of 2,4-D (commercial version DMA 806 BR). Parrot’s feather shoots (20 cm) were transplanted into plastic containers and each treatment had four replicates. The metric used to define control is not clearly presented.
