"PYRIDINS REPLACED BY HERBICIDES, PROCESSES FOR THEIR PREPARATION AND APPLICATION OF HERBICIDES AND PLANT GROWTH REGULATORS". The present invention relates to a compound of formula (I) and / or its salts, wherein R 1 is the same or different as H, halogen, CN, nitro, SF-5, (C 1-1). C ~ 8 ~) alkyl, (C ~ 2 ~ -C ~ 8 ~) alkenyl, (C ~ 2 ~ -C ~ 8 ~) alkynyl, (C ~ 1 ~ -C ~ 8 ~) alkoxy, [(C ~ (C 1 -C 8) alkyl] carbonyl or (C 1 -C 8) alkylsulfonyl, each radical being unsubstituted or substituted, S (O) R 2 R 7 where p is O, 1 or 2 and R 7 represents R (C 1 -C 8) alkyl, (C 1 -C 8) haloalkyl or NR 8 R R 9 being that R 8, R 8 and R 9 independent of each other, the same or different, are H, (C 1 -C 8) alkyl, C 2 -C 8 alkenyl, C ~ 7 ~ -C ~ 10 ~) arylalkyl, (C ~ 7 ~ -C ~ 10 ~) alkylaryl or (C ~ 6 ~ -C ~ 10 ~) aryl, each of the last five mentioned radicals being unsubstituted or substituted, or represents a group of formula (II), wherein R 10 represents R (C 1 -C 8) alkyl which is unsubstituted or substituted and W represents O or S, A is optionally substituted aryl. or represents an r optionally substituted heterocyclic cyclic, X represents O or S, R ^ 2 ^, R ^ 3 ^, R ^ 4 ^, R ^ 5 ^ the same or different, represent H, halogen, CN, (C 1 -C 8) ~) alkoxy or (C 1 -C 8) alkyl, wherein each of the two radicals mentioned above is unsubstituted or substituted, m represents 0 or 1, R 6 is H, (C 1 ~ -C ~ 8 ~) alkyl, (C ~ 1 ~ -C ~ 8 ~) alkoxy, (C ~ 2 ~ -C ~ 8 ~) alkenyl or (C ~ 2 ~ -C ~ 8 ~) alkynyl, each one of the last four mentioned radicals is unsubstituted or substituted, represents hydroxy or an acyl radical and B is an acyl radical or B and R 6 'together form a 4 or 5 membered chain, except for N-hydroxy-N- [(6-phenoxy-2-pyridyl) methyl acetamide and its salts. The compounds according to the invention are provided, for example, as herbicides and growth regulators. |
