2-Amino-4-alkylamino-6-trifluoromethylpyrimidine derivatives are used as herbicides, especially for weed control in crops

摘要

2-Amino-4-alkylamino-6-trifluoromethyl-pyrimidine derivatives (I) are used as herbicides. 2-Amino-4-alkylamino-6-trifluoromethyl-pyrimidine derivatives of formula (I) are used as herbicides. R<1> = H; and R<2> = 1-phenyl-ethyl, 1-(4-chlorophenyl)-ethyl or 4-phenoxy-butyl; or R<1> = acetyl; and R<2> = 1-phenyl-ethyl or 1-(2-phenyl-ethyl)-ethyl.
