摘要:
Novel 4-amino-6-(heterocyclic)picolinic acids and their derivatives are useful to control undesirable vegetation. The occurrence of undesirable vegetation, e.g., weeds, is a constant problem facing farmers in crops, pasture, and other settings. Weeds compete with crops and negatively impact crop yield. The use of chemical herbicides is an important tool in controlling undesirable vegetation. The invention concerns a compound of formula (I) wherein X is CF, R1 is OH or OCH3, R2 is Cl, R3, R4, R5, R6 and R6’ are H, R7 and R7’ are CH3, and A is Ar1; or an N-oxide or an agriculturally acceptable salt thereof. The invention also concerns herbicidal compositions comprising a compound of formula (I) and methods for controlling undesirable vegetation comprising applying a herbicidally effective amount of a compound of formula (I).
