Arylalkyl esters of 4-amino-6-(substituted phenyl) picolinates and 6-amino-2-(substituted phenyl)-4-pyrimidinecarboxylates and Their use as herbicides

Abstract

The present invention relates to herbicidal compound of Arylalkyl ester of 4—aminopicolinic acid and 6-amino-4-pyrimidinecarboxylate compound of formula 1 B wherein X represents H or F; Y represents halogen, Ci-C8 alkyl, C3-C6 cycloalkyl, or phenyl substituted with 1 - 4 substituents independently selected from halogen. Ci-C3 alkyl, C3-C6 cycloalkyl, C1-C3 alkoxy, C1-C3 haloalkyl, C1-C3 haloalkoxy, cyano, nitro, NRlR2, or where two adjacent substituents are taken together as —0 (CH2)nO— or —0 (CH2)n— wherein n=l or 2; Z represents halogen or C2-C4 alkenyl; R1 and R2 independently represent H, Ci-Ce alkyl, or C1-C6 acyl; R3 represents unsubstituted or substituted C7Cnarylalkyl; are herbicide for control of weeds especially those species common to rice and wheat cropping system and in pasture management program.
