EPA is revoking certain tolerances for the fungicides chloroneb and thiabendazole; the herbicide sulfosate; the defoliant thidiazuron; the insecticides cypermethrin, methidathion, and pirimiphos-methyl; and the soil microbiocide nitrapyrin. Also, EPA is modifying certain tolerances for the fungicides chloroneb and thiabendazole; the herbicides oxyfluorfen and tebuthiuron; the defoliants thidiazuron and tribuphos; the insecticides cypermethrin, methidathion, and pirimiphos-methyl; and the soil microbiocide nitrapyrin. In addition, EPA is establishing new tolerances for the fungicides chloroneb and thiabendazole; the herbicide oxyfluorfen; the defoliants thidiazuron and tribuphos; the insecticides cypermethrin, methidathion, and pirimiphos-methyl; and the soil microbiocide nitrapyrin. 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).
