BROADLEAF CROP CONTROL WITH 6-ARYLPICOLINE CARBOXYLIC ACIDS, 2-ARYLPYRIMIDINE CARBOXYLIC ACIDS, OR SALTS OR ESTERS THEREOF

摘要

Disclosed herein are methods of controlling a broadleaf volunteer crop, comprising applying to the broadleaf volunteer crop, an area adjacent the broadleaf volunteer crop, or to soil or water to prevent the emergence or growth of the broadleaf volunteer crop, a herbicidally effective amount of a 6-arylpicoline carboxylic acid, a 2-arylpyrimidine carboxylic acid, or a salt or ester thereof.

主权项

1. A method of controlling a broadleaf volunteer crop, comprising:
applying to the broadleaf volunteer crop, an area adjacent the broadleaf volunteer crop, or to soil or water to prevent the emergence or growth of the broadleaf volunteer crop, a herbicidally effective amount of a herbicide of Formula (I) or its salts or esters: wherein R1 is halogen, trifluoromethyl, cyano, substituted or unsubstituted C1-C4 alkyl, or substituted or unsubstituted C1-C4 alkoxy; R2 is hydrogen, halogen, trifluoromethyl, cyano, substituted or unsubstituted C1-C4 alkyl, substituted or unsubstituted C2-C4 alkenyl, substituted or unsubstituted C2-C4 alkynyl, or substituted or unsubstituted C1-C4 alkoxy; R3 is hydrogen, halogen, substituted or unsubstituted C1-C4 alkyl, or substituted or unsubstituted C1-C4 alkoxy; R4 is halogen, substituted or unsubstituted C1-C4 alkyl, substituted or unsubstituted C2-C4 alkenyl, substituted or unsubstituted C2-C4 alkynyl, or substituted or unsubstituted C1-C4 alkoxy; and X is N or CR5, wherein R5 is hydrogen or halogen, and wherein optionally R1 and R2 are combined to form —OCH2O, —OCHFO—, or —OCF2O—, wherein the broadleaf volunteer crop is genetically modified.
