Lorsban continues to be available to vegetable growers in Michigan
EPA announces that chlorpyrifos (Lorsban) will continue to be an available insecticide for Michigan vegetable growers.
Chlorpyrifos (Lorsban) will continue to be available to Michigan vegetable growers after a recent Environmental Protection Agency (EPA) decision. This insecticide has been in use since 1965 and EPA has been considering banning its use because of its potential to persist in the environment for long periods, leach into groundwater and cause learning disabilities and memory loss in farm workers and children.
Most often it is used in vegetables as a soil or at-planting treatment for root damaging insects, such as maggot larvae, and is often the only option vegetable growers have to target these pests. EPA announced that next it will focus its attention on updating and revising human health assessment of chlorpyrifos to be completed by Oct. 1, 2020, in order to support future decision-making.
