Abstract: Provided are an ortho-substituted phenylisoxazoline-based compound with 2,6-difluorobenzyloxymethyl represented by Formula 1, or a racemate or enantiomer thereof, a herbicide including the ortho-substituted phenylisoxazoline-based compound, or the racemate or enantiomer thereof as an active ingredient, and a method of selectively controlling grass weed comprising treating with the ortho-substituted phenylisoxazoline-based compound, or the racemate or enantiomer thereof before or after the grass weed emerges.

Abstract: Provided is an industrial method for the preparation of [5-{(2,6-difluorobenzyloxy)methyl}-4,5-dihydro-5-methyl-3-(3-methylthiophene-2-yl)-isoxazole](common name: methiozolin) represented by Formula 1 that is a herbicidal substance in high-purity.

Abstract: Provided are an ortho-substituted phenylisoxazoline-based compound with 2,6-difluorobenzyloxymethyl represented by Formula 1, or a racemate or enantiomer thereof, a herbicide including the ortho-substituted phenylisoxazoline-based compound, or the racemate or enantiomer thereof as an active ingredient, and a method of selectively controlling grass weed comprising treating with the ortho-substituted phenylisoxazoline-based compound, or the racemate or enantiomer thereof before or after the grass weed emerges.

Abstract: A method of selectively controlling annual bluegrass and/or goosegrass in turf grass, the method includes applying 5-benzyloxymethyl-1,2-isoxazoline derivative compounds, pre-emergence or post-emergence, to goosegrass and/or annual bluegrass in turf grass.

Abstract: A method of selectively controlling annual bluegrass and/or goosegrass in turf grass, the method includes applying 5-benzyloxymethyl-1,2-isoxazoline derivative compounds, pre-emergence or post-emergence, to goosegrass and/or annual bluegrass in turf grass.

Abstract: The present invention relates to a turf herbicide comprising, as an active ingredient, of 5-benzyloxymethyl-1,2-isoxazoline derivatives of formula (I), which have been known as an a rice paddy herbicide. In addition, 5-benzyloxymethyl-1,2-isoxazoline derivatives of the present invention have a high activity not only as a turf herbicide but also as a herbicide for upland crops and direct-seeded rice. As such, the derivatives of the present invention can be used either as an upland herbicide or as a herbicide for direct-seeded paddy field rice.

Abstract: The present invention relates to a method of controlling weeds in a turf grass using a sulfonylurea compound. More specifically, the present invention relates to a turf grass herbicide which comprises as an effective component a benzene sulfonylurea derivative compound that is represented by the Formula (I), or a thiophene sulfonylurea derivative compound that is represented by the Formula (II), and a method of controlling selectively poaceae, cyperaceae and broadleaf weeds by using the sulfonylurea compounds.
