Abstract
Novel 2-naphthyridinyloxy(or thio)phenoxy propanoic acid compounds of the formula ##STR1## wherein ##STR2## represents a 6 membered nitrogen containing an aromatic ring which forms a 1,5-, 1,6-, 1,7- or 1,8-naphthyridinyl moiety with the adjoining pyridine ring, said naphthyridinyl moiety optionally substituted at the 6 position of the naphthyridinyl moiety with a chloro, bromo, iodo, CF.sub.3, or fluoro atom; A represents 0 or S; and agriculturally acceptable salts, esters, ethers, and amides thereof, are useful as fungicides and herbicides, particularly effective against grassy weeds.
Claims17
A compound of the formula ##STR19## wherein ##STR20## represents a fused six-membered nitrogen-containing aromatic ring which forms a 1,5-, 1,6-, 1,7- or 1,8- naphthyridinyl moiety with the adjoining pyridine ring, said naphthyridinyl moiety optionally being substituted at the 6-position of the naphthyridinyl moiety with a chloro, iodo, CF.sub.3, bromo, or fluoro atom with the proviso that said substitution occurs only when the 6-position of said naphthyridinyl moiety is occupied by a carbon atom;
- A represents O or S;
- and
- R' represents H or C.sub.1 -C.sub.4 alkyl.
A composition comprising an inert agricultural carrier and a herbicidally effective amount of an active compound of the formula ##STR21## wherein ##STR22## represents a fused six-membered nitrogen-containing aromatic ring which forms a 1,5- 1,6-, 1,7- or 1,8 naphthyridinyl moiety with the adjoining pyridine ring, said naphthyridinyl moiety optionally being substituted at the 6-position of the naphthyridinyl moiety with a chloro, iodo, CF.sub.3, bromo, or fluoro atom with the proviso that said substitution occurs only when the 6-position of said naphthyridinyl moiety is occupied by a carbon atom;
- A represents O or S;
- and
- R' represents H or C.sub.1 -C.sub.4 alkyl.
A method of controlling undesired plant growth which comprises applying to the locus of said plants a herbicidally effective amount of an active compound of the formula ##STR23## wherein ##STR24## represents a fused six-membered nitrogen-containing aromatic ring which forms a 1,5-, 1,6-, 1,7- or 1,8-naphthyridinyl moiety with the adjoining pyridine ring, said naphthyridinyl moiety optionally being substituted at the 6-position of the naphthyridinyl moiety with a chloro, iodo, CF.sub.3, bromo, or fluoro atom with the proviso that said substitution occurs only when the 6-position of said naphthyridinyl moiety is occupied by a carbon atom;
- A represents O or S;
- and
- R' represents H or C.sub.1 -C.sub.4 alkyl.
