Abstract: 4-Amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylic acid (halauxifen) or 4-amino-3-chloro-5-fluoro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylic acid or agriculturally acceptable esters or salts of either are used for selective pre-emergence and post-emergence control of undesirable vegetation in the presence of vine crops such as grapes and other perennial crops.
