"4-AMINOPI-COLINATES AND THEIR USE AS HERBICIDES". 4-Aminopicolinic acids, having halogen, alkoxy, alkylthio, aryloxy, heteroaryloxy or trifluoromethyl substituents at positions 3, 5 and 6, and their amine and acid derivatives of formula (I) where X represents H, halogen, C ~ 1 ~ - C ~ 6 ~ alkoxy, C ~ 1 ~ - C ~ 6 ~ alkylthio, aryloxy, nitro or trifluoromethyl; Y represents halogen, C ~ 1 ~ - C ~ 6 ~, alkoxy, C ~ 1 ~ - C ~ 6 ~ alkylthio, aryloxy, heteroaryloxy or trifluoromethyl; Z represents halogen, C ~ 1 ~ - C ~ 6 ~ alkoxy, C ~ 1 ~ - C ~ 6 ~, alkylthio, aryloxy or nitro; and W represents -NO ~ 2 ~, -N ~ 3 ~, -NR ~ 1 ~ R ~ 2 ~, -N = CR ~ 3 ~ R ~ 4 ~ or -NHN = CR ~ 3 ~ R ~ 4 ~ are herbicides demonstrating a broad spectrum of weed control. |
