Patent number: 8492310Abstract: Many herbicidal compositions have been developed and used, but there are many types of weeds to be controlled, and their development lasts for a long period of time. Accordingly, it has been desired to develop a herbicidal composition having a wider herbicidal spectrum and having a highly active and long-lasting herbicidal activity. The present invention provides a herbicidal composition which comprises as active ingredients (a) a herbicidal benzoylpyrazole compound represented by the formula (I) or its salt: wherein R1 is alkyl or cycloalkyl, R2 is a hydrogen atom or alkyl, R3 is alkyl, R4 is alkyl, haloalkyl or the like, R5 is a hydrogen atom, alkyl or the like, R6 is haloalkyl, halogen or the like, and A is alkylene substituted by alkyl, and (b) other herbicidal compound.Type: GrantFiled: December 10, 2009Date of Patent: July 23, 2013Assignee: Ishihara Sangyo Kaisha, Ltd.Inventors: Hiroshi Kikugawa, Souichiro Nagayama, Makiko Sano

Patent number: 8466088Abstract: 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.Type: GrantFiled: February 1, 2008Date of Patent: June 18, 2013Assignee: Ishihara Sangyo Kaisha, Ltd.Inventors: Hiroshi Shimoharada, Masamitsu Tsukamoto, Masahiko Ikeguchi, Hiroshi Kikugawa, Souichiro Nagayama, Makiko Sano, Yoshinori Kitahara, Hidemasa Kominami, Tatsuya Okita
