"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."
