さらに、特開２００７−６３１５１号公報では、１,１−ジクロロ−Ｎ−（ジメチルアミノ）スルホニル−１−フルオロ−Ｎ−（４−メチルフェニル）メタンスルフェンアミドを含有することを特徴とする揮散性防黴剤組成物が開示されている。
しかしながら、これらの防黴剤では、防虫効果の持続性が不十分になったり、臭いの面で問題があったり、防虫効果が不十分であったりするなどの問題があり、検討が十分になされているとはいえなかった。
Conventionally, various insect repellents are commercially available for controlling pests inhabiting in homes, in particular, clothing pests such as moths, moths, cutlet worms, and worms. When these insect repellent components are used in a chiffon or drawer, if the moisture in the repellent becomes high, wrinkles are likely to grow on clothes and the like, so that a preparation having an antibacterial performance in addition to the insect repellent effect is desired. For this reason, for example, a preparation in which a phenolic antifungal agent such as 2-phenylphenol, 4-isopropyl-3-methylphenol, p-chloro-m-xylenol, thymol and the like is added to empentrin is commercially available. -298619 discloses the use of hinokitiol.
In addition, JP-A-2001-213712 discloses components (A) and (B) [(A) pyrethroid compounds and / or 2-phenoxyethanol (B) N- (fluorodichloromethylthio) -phthalimide and / or N -Dichlorofluoromethylthio-N ', N'-dimethyl-N-phenylsulfamide] containing an antifungal insect repellent composition, an antifungal repellent formulation, and the above components, as well as component (C) [(C) 3- An antifungal repellent composition and an antifungal repellent preparation containing iodo-2-propynylbutylcarbamate and / or orthophenylphenol] are disclosed.
Further, JP-A-2007-63151 discloses volatilization characterized by containing 1,1-dichloro-N- (dimethylamino) sulfonyl-1-fluoro-N- (4-methylphenyl) methanesulfenamide. An antifungal composition is disclosed.
However, these antifungal agents have problems such as insufficient sustainability of the insect repellent effect, problems in terms of smell, and insufficient insect repellent effect. I couldn't say.
本発明は、防黴成分と防虫成分を併用した際に、両方の効果が十分に、かつ持続的に得られるとともに、実質的に臭いがない防黴防虫組成物及びこれを用いた防黴防虫方法を提供することを課題とする。 The present invention provides a fungicide / insect repellent composition having both effects sufficiently and continuously obtained and having substantially no odor when using a fungicide component and an insect repellent component together, and a fungicide / insect repellent using the same It is an object to provide a method.
上記課題を解決するため、本発明者らは、鋭意検討を重ねた結果、木材保存用の防黴成分として用いられていたイソチアゾリン系防黴成分に、優れた空間用としての防黴効果を見出した。しかる後、この防黴成分を防虫成分と組み合わせて使用することによって、防黴効果と防虫効果が補完的に向上し、目的とする防黴防虫組成物、ならびにこれを用いた有用な防黴防虫方法を提供できることを知見し、本発明を完成した。

In order to solve the above-mentioned problems, the present inventors have made extensive studies, and as a result, found an isthiazoline-based antifungal component used as an anti-fungal component for preserving wood, and found an excellent antifungal effect for space use. It was. Thereafter, by using this fungicide component in combination with an insect repellent component, the fungicide effect and the insect repellent effect are complementarily improved, and the intended fungicide and insect repellent composition, and a useful fungicide and insect repellent using the same It was found that a method could be provided, and the present invention was completed.
That is, the present invention has the following configuration.
(1) An antifungal and insecticidal composition containing an isothiazoline-based antifungal component and an insecticidal component.
(2) The antifungal and insecticidal composition according to (1), wherein the blending ratio of the isothiazoline-based antifungal component and the insecticidal component is in the range of 0.01: 1 to 0.5: 1.

別に寒天培地を入れ固めたシャーレを培地面を下向きにして置き、容器内には、精製水を入れて湿度を調整した。ステンレス容器に蓋をし、２５℃±２℃で７日間保存し、内部から寒天培地を取り出し、別に黴胞子懸濁液を含浸したペーパーディスクを用意し、寒天培地の中央に置き、このまま蓋を被せて２５℃±２℃で５日間培養した。培養後の発育した黴の発育直径を算出し、防黴効果の評価を行った。また対照品として、他の防黴成分を含有したものを作成し、同様の方法で試験した。
防黴効果の評価基準：○（発育直径が対照の６０％を超えないとき）、△（発育直径が対照の６０〜８０％のとき）、×（発育直径が対照の８０％より大きいとき）
Antifungal test method:
The inside of a stainless steel container with an internal volume of 50 L, which can be sealed with silicon packing, was sterilized with 75% alcohol. The antifungal and insect repellent composition of the invention was dispensed into test pieces and placed in a plastic container and placed in this container.
Separately, a petri dish containing an agar medium and solidified was placed with the medium surface facing downward, and purified water was placed in the container to adjust the humidity. Cover the stainless steel container and store at 25 ° C ± 2 ° C for 7 days. Remove the agar medium from the inside and prepare another paper disk impregnated with the spore suspension and place it in the center of the agar medium. Cultivated at 25 ° C. ± 2 ° C. for 5 days. The growth diameter of the cocoon grown after the culture was calculated, and the antifungal effect was evaluated. Further, as a control product, a product containing other antifungal ingredients was prepared and tested in the same manner.
Evaluation criteria for antifungal effect: ○ (when growth diameter does not exceed 60% of control), △ (when growth diameter is 60-80% of control), × (when growth diameter is greater than 80% of control)
防虫試験方法（食害防止試験方法）：
内容積５０Ｌの衣装ケース内いっぱいに５枚のモスリン布を重ねて収納し、その上に、本発明の防黴防虫組成物を分注したマットをプラスチック容器にいれたものを置いた。
試験開始直後、試験開始６ヶ月後及び試験開始１２ヶ月後に、底から３枚目及び５枚目のモスリン布の上にイガ幼虫６０匹を放虫し、放虫１週間後のモスリン布での食害状況を調べた。なお、食害状況の結果は以下の基準で評価した。
○：（全く食害なし）
△：（わずかな食害あり）
×：（明らかに食害が認められる）
Insect protection test method (food damage prevention test method):
Five muslin cloths were stacked and stored in a 50 L internal clothing case, and a plastic container containing a mat dispensed with the fungicide and insect repellent composition of the present invention was placed thereon.
Immediately after the start of the test, 6 months after the start of the test and 12 months after the start of the test, 60 moth larvae were released on the 3rd and 5th muslin cloth from the bottom, and the muslin cloth 1 week after the release. The state of eating damage was investigated. The results of the damage status were evaluated according to the following criteria.
○: (No damage at all)
Δ: (Slightly damaged)
×: (Estimately eating damage is recognized)
臭いの試験
使用開始時のステンレス容器内の臭いを、10人のモニターで評価した。
臭いの評価：○（臭いなし）、△（わずかに臭いあり）、×（明らかに臭いが認められる）
Odor test The odor in the stainless steel container at the start of use was evaluated by 10 monitors.
Odor evaluation: ○ (no odor), △ (slightly odor), × (obviously odor is recognized)
試験の結果、本発明の防黴防虫組成物を用いたものは、いずれも高い防黴効果が初期から１２ヶ月後まで、継続して持続した。また、防虫効果においても同様であった。さらに臭いにおいてもいずれも臭いがないかわずかに臭う程度で、実用上の問題はなかった。
これに対して、比較例のフェノール系の防黴成分を使用したものでは、防虫効果に問題はなかったが、初期から防黴効果が不十分であった。また臭いの点でも、いずれも臭いが強く実用上、好ましくなかった。また、イソチアゾリン系防黴剤を単独で使用し、添加量を増やした場合には、初期の防黴効果は認められたが、６ヶ月後には防黴効果は低下した。
As a result of the test, all the antifungal and insecticidal compositions according to the present invention maintained a high antifungal effect continuously from the initial stage to 12 months later. The same was true for the insect repellent effect. Furthermore, there was no problem in practical use even in the case of odor.
On the other hand, in the case of using the phenolic antifungal component of the comparative example, there was no problem in the insect repellent effect, but the antifungal effect was insufficient from the beginning. Also, in terms of odor, all of them were strong in odor and were not preferable for practical use. When the isothiazoline antifungal agent was used alone and the amount added was increased, the initial antifungal effect was recognized, but the antifungal effect decreased after 6 months.
実施例４と同様の方法で、サンプルを作成し、試験を実施した。結果を表３に示す。
○：（着色なし）
○〜△：（わずかな着色あり）
△：（着色あり）
Samples were prepared and tested in the same manner as in Example 4. The results are shown in Table 3.
○: (No coloring)
○ to △: (Slight coloration)
Δ: (colored)
実施例４と同様の方法で、サンプルを作成し、これを内層がポリエチレン製のフィルムに包装し、４０℃に保管し、各々の時期に回収して防虫成分の回収率を調査した。結果を表４に示す。
A sample was prepared in the same manner as in Example 4, and the inner layer was packaged in a polyethylene film, stored at 40 ° C., collected at each period, and examined for the insecticidal component recovery rate. The results are shown in Table 4.
試験の結果、本発明の防黴防虫組成物は、いずれも６ヵ月後まで、９８％以上の回収率を示し、防虫成分の回収率が高く、優れていた。それに対して、エムペントリンのみ及びプロフルトリンのみの比較例１及び２では、回収率は低かった。
As a result of the test, all of the antifungal and insecticidal compositions of the present invention exhibited a recovery rate of 98% or more until 6 months later, and the recovery rate of the insect repellent components was high and excellent. On the other hand, in the comparative examples 1 and 2 using only empentrin and only profluthrin, the recovery rate was low.
本発明の防黴防虫組成物及びこれを用いた防黴防虫方法は、室内の各種空間に揮散させて効果を発揮させることが出来るので、防黴効果と防虫効果が必要とされる場面で利用可能である。 The antifungal and insecticidal composition of the present invention and the antifungal and insecticidal method using the composition can be used in situations where an antifungal effect and an insecticidal effect are required because they can be volatilized in various indoor spaces to exert their effects. Is possible.
