BENZYL-4-AMINOPYCOLINIC ESTERS AND REPLACED PYRIMIDINE-4-CARBOXYL ESTERS, METHODS FOR THE PRODUCTION OF THE SAME, AND USE OF THE SAME AS HERBICIDES AND PLANT GROWTH REGULATORS

摘要

the present invention relates to benzyl-4-aminopicolinic esters and substituted pyrimidine-4-carboxylic esters, methods for producing them, and their use as herbicides and plant growth regulators. benzylcarboxylic acid derivatives of benzoheterocyclylpyridines and benzoheterocyclylpyrimidines of the general formula (i) are described and their use as herbicides in which x represents ch or cf, a represents a benzo-fused heterocycle, r1 represents h, hal or organic radicals , as alkyl, and r2 represents cl or f.
