HERBIZIDE PHENOXYPROPIONSÄURE-N-ALKYL-N-2- FLUOROPHENYLAMID-VERBINDUNGEN

摘要

The present invention relates to novel herbicidal phenoxypropionic acid N-alkyl-N-2-fluorophenyl amides represented in formula (1), a method for preparing thereof, their use to control barnyard grass produced from rice and composition as suitable herbicides. In said formula, R is methyl or ethyl group; X is hydrogen, halogen, cyano, C1~C6 alkyl, C1~C6 alkoxy, C1~C3 haloalkyl substituted with 1 to 3 of halogen atom(s), C1~C3 haloalkoxy substituted with 1 to 3 of halogen atom(s), C2~C4 alkoxyalkoxy, phenoxy, benzyloxy, C2~C6 alkenyl, C2~C6 alkinyl, C2~C6 alkkenyloxy, C2~C6 alkinyloxy, or phenyl group; Y is hydrogen or fluoro; n is an integer of 1 or 2 and when n is 2, X can be in a combination of other substituents.
