摘要:
Herbicidal fluorovinyloxyacetamide compounds of formula (I) are useful for protecting crops from weeds: wherein: R1 is a phenyl group optionally having one or more substituents selected from the group consisting of C1-6 alkyl, halogen-substituted C1-6 alkyl, C1-6 alkoxy and halogen; R2 is a C1-6 alkyl; or R1 and R2 together with the nitrogen atom to which they are bound form a 5-, 6- or 7-membered nitrogen heterocycle optionally having one or more ring oxygen atoms, double bonds and C1-6 alkyl substituents; R3 is a phenyl or thiophen-2-yl group optionally having one or more substituents selected from the group consisting of C1-6 alkyl, halogen-substituted C1-6 alkyl, C1-6 alkoxy, methylenedioxy and halogen; and R4is a perfluoro C1-6 alkyl group.
摘要:
The present invention provided with novel 5-benzyloxymethyl-1,2-isoxazoline derivatives of the formula (1), their preparation method and their use as herbicides. The 5-benzyloxymethyl-1,2-isoxazoline derivatives according to the present invention have sufficiently high herbicidal activity against the weeds in the paddy field rice even at low dose rates and excellent selectivity to transferred rice in particular. As thus, the compounds of the present invention are typically useful as herbicides for control of paddy weeds in rice.
