The content of component (C) is preferably 5 to 45% by mass, more preferably 10 to 30% by mass, even more preferably 15 to 30% by mass, based on the total mass of the control agent composition. When it is within the above range, it is easy to enhance the microbial control effect, and it is easy to enhance the sustainability. Moreover, it is excellent in compatibility of the (B) component in a composition as it is below the said upper limit.
防除剤組成物の総質量に対して、(A)成分と(C)成分の合計の含有量は、65~99.9質量%であり、75~95質量%が好ましく、80~89質量%がより好ましい。上記範囲の上限値以下であると良好な微生物防除効果が得られやすく、下限値以上であると、微生物防除効果の良好な持続性が得られやすい。

The total content of components (A) and (C) is 65 to 99.9% by mass, preferably 75 to 95% by mass, more preferably 80 to 89% by mass, based on the total mass of the control agent composition. When the content is equal to or less than the upper limit value of the above range, a good microbial control effect is likely to be obtained, and when it is equal to or more than the lower limit value, it is easy to obtain a good persistence of the microbial control effect.
The mass ratio (A)/(C) of component (A) to component (C) is 0.6 to 20, preferably 1 to 8, more preferably 2 to 5. When it is at least the lower limit value of the above range, a good microbial control effect is likely to be obtained, and when it is at most the upper limit value, it is easy to obtain a good persistence of the microbial control effect.
Although the reason why component (C) contributes to the improvement of the microbial control effect and the improvement of sustainability is not clear, it is believed that component (A) and component (B1) act effectively against microorganisms because the humidity in the space increases due to volatilization of component (C).
