Description
本発明は、水で希釈した際に、分離や白濁したり沈殿物が生じたりしない殺虫殺菌剤組成物に関する。 The present invention relates to an insecticidal fungicide composition that does not separate, become cloudy or precipitate when diluted with water.
従来、農作物や木材、畳などから害虫を防除したり、腐食や病気感染などの原因となる微生物を防除したりする薬剤として、殺菌成分と殺虫成分とを含む殺虫殺菌剤組成物が開発されている（例えば、特許文献１）。殺虫殺菌剤組成物などの薬剤を保管する際に保管場所の省スペース化や薬剤の運搬を容易にするため、殺菌成分や殺虫成分などの有効成分を、組成物中に高濃度で含有させた製剤が開発されている。このような製剤には、乳剤や水和剤などが用いられている。このような殺虫殺菌剤組成物は、施用時に必要に応じて水で希釈して使用される。 Conventionally, an insecticidal fungicide composition containing a bactericidal component and an insecticidal component has been developed as a chemical to control pests from crops, wood, tatami, etc., and to control microorganisms that cause corrosion and disease infection. (For example, Patent Document 1). When storing medicines such as insecticidal fungicide compositions, active ingredients such as bactericidal ingredients and insecticidal ingredients are included in the composition at high concentrations in order to save space and facilitate the transportation of the medicine. Formulations are being developed. In such preparations, emulsions and wettable powders are used. Such an insecticidal fungicide composition is used by diluting with water as needed at the time of application.
しかし、乳剤や水和剤などを用いた殺虫殺菌剤組成物は、水で希釈すると分離したり沈殿物が生じたりしやすく、殺菌成分および殺虫成分を均一に処理することが困難であるという問題がある。そこで、特許文献２には、このような分離や沈殿を防止するために、殺菌成分と殺虫成分とを含む水性懸濁剤中に水溶性セルロースを配合することが記載されている。 However, an insecticidal fungicide composition using an emulsion or a wettable powder tends to separate or precipitate when diluted with water, and it is difficult to uniformly treat the fungicidal component and the insecticidal component. There is. Therefore, Patent Document 2 describes that water-soluble cellulose is blended in an aqueous suspension containing a bactericidal component and an insecticidal component in order to prevent such separation and precipitation.
水溶性セルロースを配合すると、分離や沈殿を抑制する若干の効果が発揮されるものの、その効果は不十分であり、殺虫殺菌剤組成物を均一に処理するには満足できるものではない。そのため、簡便に殺菌成分および殺虫成分を均一に処理できる殺虫殺菌剤組成物が求められている。 When water-soluble cellulose is blended, some effects of suppressing separation and precipitation are exhibited, but the effects are insufficient, and it is not satisfactory for uniformly treating the insecticidal fungicide composition. Therefore, an insecticidal fungicide composition that can easily and uniformly treat the bactericidal component and the insecticidal component is desired.
本発明の課題は、水で希釈した際に、分離や白濁したり沈殿物が生じたりしない殺虫殺菌剤組成物を提供することである。 An object of the present invention is to provide an insecticidal fungicide composition that does not separate, become cloudy or precipitate when diluted with water.
本発明者は、上記課題を解決するべく鋭意検討を行った結果、以下の構成からなる解決手段を見出し、本発明を完成するに至った。

表１および３に示すように、実施例１〜８で得られた殺虫殺菌剤組成物は、水で希釈して常温で保管しても、白濁や分離したり、あるいは沈殿物が生じたりしていないことがわかる。一方、表２および３に示すように、比較例１〜９で得られた殺虫殺菌剤組成物は、水で希釈して常温で保管すると、白濁や分離したり、あるいは沈殿物が生じたりしており、水性製剤としての安定性に劣ることがわかる。 As shown in Tables 1 and 3, the insecticidal fungicide compositions obtained in Examples 1 to 8 may become cloudy or separated, or precipitates may be formed even when diluted with water and stored at room temperature. You can see that it is not. On the other hand, as shown in Tables 2 and 3, when the insecticidal fungicide composition obtained in Comparative Examples 1 to 9 is diluted with water and stored at room temperature, it may become cloudy or separated, or a precipitate may be formed. This indicates that the stability as an aqueous preparation is poor.
このように、ＰＯＥ硬化ヒマシ油とＰＯＥアルキルエーテルとの両方を含み、これらのＨＬＢ値の加重平均を１０〜１２の範囲とすることによって、水での希釈時に白濁や分離したり、あるいは沈殿物が生じたりしない殺虫殺菌剤組成物が得られる。このような殺虫殺菌剤組成物は、均一に殺菌成分および殺虫成分を処理できる効果が期待される。 Thus, by including both POE hydrogenated castor oil and POE alkyl ether, and making the weighted average of these HLB values be in the range of 10-12, white turbidity or separation at the time of dilution with water, or precipitates Thus, an insecticidal fungicide composition that does not cause the occurrence of odor is obtained. Such an insecticidal fungicide composition is expected to have an effect of uniformly treating the fungicidal component and the insecticidal component.
