Herbicide Applications Undermining Protection of Biodiversity | The Barley Mow | Scoop.it

"The study, funded by the U.S Fish and Wildlife Service (FWS) and published in the journal Environmental Pollution, is one of the first to document the effects of herbicides on butterflies. Several studies have shown herbicides can adversely affect animal life, even though they are designed to kill plants. Since each herbicide in the Behr’s metalmark research has a different mode of action, Dr. Stark speculates that their toxic effects may be due to inert ingredients contained but not identified in the formulations, or indirect effects on food plant quality. Of the three herbicides studied, refuge managers now use only triclopyr, mainly on woody plants and trees in areas far away from prime butterfly habitat."
