HERBICIDAL PHENOXYPROPIONIC ACID N-ALKYL-N-2-FLUOROPHENYL AMIDE COMPOUNDS

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 an d composition as suitable herbicides. In said formula, R is methyl or ethyl group; X is hydrogen, halogen, cyano, C1C6 alkyl, C1C6 alkoxy, C1C3 haloalky l substituted with 1 to 3 of halogen atom(s), C1C3 haloalkoxy substituted with 1 to 3 of halogen atom(s), C2C4 alkoxyalkoxy, phenoxy, benzyloxy, C2C6 alkenyl , C2C6 alkinyl, C2C6 alkenyloxy, C2C6 alkinyloxy, or phenyl group; Y is hydrog en or fluoro; n is an integer of 1 or 2 and when n is 2, X can be in a combination of other substituents.
