Herbicide Applications Undermining Protection of Biodiversity

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."

West Coast Salmon: Pesticides Put Protected Species In Jeopardy

West Coast Salmon: Pesticides Put Protected Species In Jeopardy | The Barley Mow | Scoop.it

"A draft federal evaluation has found that three more common pesticides used on home lawns and agricultural crops jeopardize the survival of West Coast salmon.

The evaluation from NOAA Fisheries Service is the latest one resulting from lawsuits filed by conservation groups and salmon fishermen demanding the U.S. Environmental Protection Agency enforce restrictions on pesticides around salmon streams.

This one looked at the pre-emergent herbicides oryzalin, pendimenthalin and trifluralin. They are used to control weeds in lawns, on road shoulders, in orchards, vineyards, and farm fields growing soybeans, cotton, corn, Christmas trees and other crops. Heaviest use is in California. The herbicides are ingredients in more than 100 commercial products made by dozens of manufacturers."
