ARYLALKYL ESTERS OF 4-AMINO-6-(SUBSTITUTED PHENYL)-PICOLINATES AND 6-AMINO-2-(SUBSTITUTED PHENYL)-PYRIMIDINECARBOXYLATES AND THEIR USE AS SELECTIVE HERBICIDES FOR CROPS

摘要

Arylalkyl esters of 4-aminopicolinic acids and 6-amino-4-pyrimidinecarboxylates are herbicides for control of weeds especially those species common to rice and wheat cropping systems and in pasture management programs.
