The manufacturer of a pesticide that is believed to pose unacceptable dietary risks has agreed to end all uses of the chemical in the U.S.
Bayer CropScience and the U.S. Environmental Protection Agency reached an agreement that will halt all uses of the pesticide aldicarb, sold under the trade name Temik, no later than September 2018. Bayer will phase out production of aldicarb by Dec. 31, 2014.
Citrus and potatoes will be the first crops that will be unable to use the chemical, and Bayer has agreed to adopt risk mitigation measures for protection of groundwater resources. New measures to protect shallow drinking water wells in vulnerable areas of the southeastern U.S. coastal plain and lower application rates will be immediately added to product labels for use on cotton, soybeans and peanuts.
Additionally, the EPA plans to revoke the tolerances (legal pesticide residues allowed in food) associated with these commodities.
Based upon current toxicological studies, aldicarb at levels higher than those typically found in food has the potential to cause various effects such as sweating, nausea, dizziness and blurred vision, abdominal pain, vomiting, and diarrhea.
Aldicarb is registered for use as a systemic insecticide and nematicide on agricultural crops, and is formulated and marketed solely as a granular pesticide. During the phase-out, the pesticide will continue to be registered for use on cotton, dry beans, peanuts, soybeans, sugar beets, and sweet potatoes. Aldicarb products are not intended for sale to homeowners or for use in residential settings. A restricted use pesticide, aldicarb may be applied only by trained, certified pesticide applicators.
