EPA is revoking certain tolerances for the fungicides prothioconazole and thiabendazole; the herbicide primisulfuron-methyl; and the insecticides azinphos-methyl, disulfoton, esfenvalerate, fenvalerate, and phosalone; the plant growth regulator 1- naphthaleneacetic acid; and the antimicrobial/insecticidal agent ethylene oxide. Also, EPA is modifying certain tolerances for the insecticides disulfoton, esfenvalerate, and phosmet; and the plant growth regulator 1-naphthaleneacetic. In addition, EPA is establishing new tolerances for the insecticides disulfoton, esfenvalerate, and phosmet; and the antimicrobial/insecticidal agent ethylene oxide and ethylene chlorohydrin (a reaction product formed during the fumigation/ sterilization process). The regulatory actions finalized in this document are in follow-up to the Agency's reregistration program under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and tolerance reassessment program under the Federal Food, Drug, and Cosmetic Act (FFDCA), section 408(q).
