PROBLEM TO BE SOLVED: To provide new means and method to effectively control a noxious organism that cannot be controlled or is difficult to be controlled because there is a case that cannot perform effective control respectively alone by the reason of the kind of an object noxious organism or the like, the differential effect by living characteristics or the like, and a resistant development or the like.SOLUTION: The use of flubendiamide and thiosultap or a salt thereof in combination can produce a significant synergistic control effect, even when each of the components is used in an amount in which a satisfactory control effect cannot be achieved when used singly. The use of these components in combination can produce a significant control effect against noxious organisms that cannot be controlled when each of the components is used singly and noxious organism that have resistance to commercially available control agents.COPYRIGHT: (C)2013,JPO&INPIT【課題】各々単独では、対象有害生物等の種類、生息特性等による効果差、抵抗性の発達等の理由で有効な防除ができない場合があり、防除不可能な又は困難な有害生物を効率的に防除するための新たな手段及び方法。【解決手段】 各々単独では十分な防除効果が得られなかった薬量でも、フルベンジアミドとチオスルタップ又はその塩とを組み合わせて使用することにより、顕著な相乗効果を発揮し、単独では防除できなかった有害生物、及び市販剤に対して抵抗性等を示す有害生物に対しても顕著な防除効果を有する。【選択図】なし
