Pesticides Tolerance Reassessment Actions; 4-Amino-6-(1,1- dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one [Metribuzin], Dichlobenil, Diphenylamine, O-Ethyl O-[4-(methylthio) phenyl] S-propyl phosphorodithioate [Sulprofos], Pendimethalin, and Terbacil

Riepilogo

This document announces the proposed revocation of tolerances for the herbicides 4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4- triazin-5(4H)-one [Metribuzin], dichlobenil, pendimethalin, and terbacil; and the insecticide O-ethyl O-[4-(methylthio) phenyl] S- propyl phosphorodithioate [Sulprofos]. EPA expects to determine whether any individuals or groups want to support these tolerances. Also, this document is proposing the establishment and revision of tolerances for 4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one (metribuzin), dichlobenil, pendimethalin, terbacil, and the plant growth regulator diphenylamine. In addition, EPA is also proposing to revise commodity terminology for 4-amino-6-(1,1-dimethylethyl)-3- (methylthio)-1,2,4-triazin-5(4H)-one [Metribuzin], diphenylamine, and pendimethalin to conform to current practice. The regulatory actions in this notice are part of the Agency's reregistration program under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and the tolerance reassessment requirements of the Federal Food, Drug, and Cosmetic Act (FFDCA). By law, EPA is required to reassess 33% of the tolerances in existence on August
