CONTROL OF PHENOXYALKANOIC ACID HERBICIDE-RESISTANT WEEDS WITH 4-AMINO-3-CHLORO-6-(4-CHLORO-2-FLUORO-3-METHOXYPHENYL)PYRIDINE-2-CARBOXYLIC ACID AND ITS SALTS OR ESTERS
4-Amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylic acid and its salts or esters effectively controls phenoxyalkanoic acid herbicide-resistant weeds despite having the same mode of action as phenoxyalkanoic acid herbicides.
