"Reversing a decade-old decision, the U.S. Environmental Protection Agency announced Tuesday that it plans to require pesticide manufacturers to disclose to the public the inert ingredients in their products. An inert ingredient is anything added to a pesticide that does not kill or control a pest. In some cases, those ingredients are toxic, but companies do not identify them on pesticide labels. For 11 years, EPA denied petitions seeking disclosure of the chemicals but now the new administration says it plans to draft a rule that will increase transparency and encourage companies to replace toxic substances. Manufacturers worry about revealing trade secrets. "
