  • Patent number: 8466089
    Abstract: The present invention provides a novel herbicide showing excellent herbicidal effects, which has a wide application range including agricultural fields and non-agricultural fields and various application methods including soil treatment and foliage treatment. A pyrazole compound represented by the formula (I) or its salt: wherein R1 is alkyl, R2 is a hydrogen atom or alkyl, R3 is alkyl, R4 is alkyl, R5 is alkyl substituted by one alkoxy, alkoxy substituted by one alkoxy, or alkoxycarbonyl, R6 is alkylsulfonyl, A is alkylene substituted by at least one alkyl; a process for its production; a herbicide containing it as an active ingredient; and a method for controlling undesired plants or inhibiting their growth, which comprises applying a herbicidally effective amount thereof to the undesired plants or to a place where they grow.

  • Patent number: 8466088
    Abstract: Provided is an herbicidal composition which can be applied at a low dose as compared with individual application, and thus is effective to reduce the environmental load on a place where the composition is applied or a periphery thereof, of which the herbicidal spectrum is enlarged, and of which the herbicidal effects last over a long period of time. The herbicidal composition has as active ingredients (a) a herbicidal benzoylpyrazole compound represented by the formula (I) or its salt: wherein Q is —C(O)SR3 or a hydrogen atom, R1 is alkyl or cycloalkyl, R2 is a hydrogen atom or alkyl, R3 is alkyl, cycloalkyl or the like, R4 is alkyl, haloalkyl or the like, R5 is a hydrogen atom, alkyl or the like, R6 is haloalkyl, halogen or the like, and (b) a further herbicidal compound.
