4-AMINO-6-(HETEROCYCLIC)PICOLINATES AND 6-AMINO-2-2(HETEROCYCLIC) PYRIMIDINE-4-CARBOXYLATES AND THEIR USE AS HERBICIDES

摘要

4-Amino-6-(heterocyclic )picolinic acids, 6-amino-2-(heterocyclic )pyrimidine-4-carboxylates, and derivatives thereof are provided. Also provided are herbicidal compositions including these compounds, as well as methods of using thereof as herbicides. The occurrence of undesirable vegetation, e.g., weeds, is a constant problem facing famers 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.
