Abstract
Description
本発明は、シロアリ、ダニ、ゴキブリ、ハエ（ウジ）、蚊等の家害虫の防除（駆除および予防）に用いられる害虫防除剤に関する。 The present invention relates to a pest control agent used for control (control and prevention) of house pests such as termites, ticks, cockroaches, flies (maggots), and mosquitoes.
シロアリ、ダニ、ゴキブリ、ハエ、蚊等の家害虫と呼ばれる害虫の駆除や予防には、従来から化学薬品が使用されてきた。特にシロアリに対しては、有機リン系等の強力な薬剤が用いられてきた。しかし、薬品に対する耐性の発現や人体に対する安全性が問題となり、安全性の高い害虫防除剤の開発が求められている。
これまでに、有効成分として塩化カルシウムを使用する家害虫駆除および忌避剤が知られている（特許文献１、２）。この駆除ないし忌避作用は、塩化カルシウムが家害虫の細胞内に吸収されると、細胞内の電解バランスが崩れて、細胞膜が破壊されてしまうことによる。
Chemicals have been used in the past for the control and prevention of pests called house pests such as termites, ticks, cockroaches, flies and mosquitoes. Particularly for termites, powerful drugs such as organophosphorus have been used. However, the development of resistance to chemicals and the safety to the human body are problems, and the development of highly safe pest control agents is required.
So far, domestic pest control and repellents using calcium chloride as an active ingredient are known (Patent Documents 1 and 2). This extermination or repellent action is due to the fact that when calcium chloride is absorbed into the cells of a pest, the intracellular electrolytic balance is disrupted and the cell membrane is destroyed.
しかし、発明者の検討によれば、特に厳しい防除効果（ここで、防除とは駆除と予防の双方を含む。）が求められるシロアリ防除剤としては、上記特許文献１の塩化カルシウムの濃度を飽和濃度にまで高めても、充分な防除効果が得られず、木材食害試験および土壌貫通試験において、シロアリの死虫率を１００％とすることはできなかった。すなわち、塩化カルシウムは、シロアリのなかでもヤマトシロアリに対しては、ある程度の防除効果（土壌貫通阻止効果）は認められるものの、イエシロアリに対しては土壌貫通を阻止することができず、容易に家屋への侵入を許して甚大な損害を与えるおそれがある。 However, according to the inventor's study, as a termite control agent for which a particularly severe control effect (here, control includes both control and prevention), the concentration of calcium chloride in Patent Document 1 is saturated. Even when the concentration was increased, a sufficient control effect could not be obtained, and the termite death rate could not be made 100% in the wood feeding damage test and the soil penetration test. In other words, calcium chloride has a certain degree of control effect against soil termites (soil penetration prevention effect) among termites, but does not prevent soil termites from penetrating soils. There is a risk of incurring enormous damage by allowing intrusion into the
また、塩化カルシウムは、強い吸湿性を有する弱酸性化合物であるため、その水溶液を家屋の床下へ土壌処理した場合、飛散した塩化カルシウムによって建築物の金属部材が腐食を受けてしまう。したがって、塩化カルシウムを床下におけるシロアリ防除剤として使用する場合、注意を要した。 Further, since calcium chloride is a weakly acidic compound having a strong hygroscopic property, when the aqueous solution is treated under the floor of a house, the metallic member of the building is corroded by the scattered calcium chloride. Therefore, care was required when using calcium chloride as a termite control agent under the floor.
さらに、シロアリ駆除は、通常、土壌処理と木部処理の双方を行う必要があり、それぞれ適用箇所に合致した防除剤が選択・使用されていた。
しかし、土壌処理と木部処理とで異なる防除剤を使用する場合、それぞれを散布する噴霧器を複数、現場に用意するか、あるいは、薬液を変えるたびに噴霧器の洗浄等を行う必要があり、コスト面でも、労力面でも改善が求められていた。
そこで本発明は、上記問題点を解決し、家害虫、特にシロアリに対する防除効果が高く、かつ、人体に対して安全な防除剤を提供することを目的とする。
Further, termite control usually requires both soil treatment and xylem treatment, and a control agent that matches each application site has been selected and used.
However, when using different control agents for soil treatment and xylem treatment, it is necessary to prepare multiple sprayers to spray each, or to clean the sprayer every time the chemical solution is changed. Improvements were required both in terms of labor and labor.
Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a control agent that has a high control effect on house pests, particularly termites, and is safe for the human body.
本発明は、塩化カルシウム、界面活性剤、防錆剤、および水を含む害虫防除剤に関する。
別の本発明は、上記本発明に係る害虫防除剤を土壌処理および／または木部処理に使用するシロアリ防除方法に関する。
この害虫防除剤を用いた処理（散布または塗布）の際に、硫酸塩またはアルギン酸塩、好ましくは硫酸カルシウム、硫酸バリウム、またはアルギン酸ナトリウムを事前に、同時に、または事後に散布または塗布することにより、より効果的なシロアリ防除が可能となる。
The present invention relates to a pest control agent containing calcium chloride, a surfactant, a rust inhibitor, and water.
Another aspect of the present invention relates to a termite control method using the pest control agent according to the present invention for soil treatment and / or xylem treatment.
During the treatment (spraying or application) with this pest control agent, by applying or applying a sulfate or alginate, preferably calcium sulfate, barium sulfate or sodium alginate in advance, simultaneously or afterwards, More effective termite control becomes possible.
本発明では、塩化カルシウムに界面活性剤および防錆剤を組み合わせることにより、塩化カルシウムの展着性を高めて高い防除効果が得られるとともに、床下の金属部材に対して金属腐食性の問題のない害虫防除剤を得ることができる。
さらに、硫酸塩またはアルギン酸塩、たとえば硫酸カルシウム、硫酸バリウム、またはアルギン酸ナトリウムを併用することにより、害虫と塩化カルシウムとの接触時間を増やすことで相乗効果が得られ、顕著に高い防除効果を得ることができる。その結果、ヤマトシロアリのみならずイエシロアリを含む様々なシロアリに対して高い殺虫効果を示し、家屋を有効に予防することができる。
また、本発明に係る害虫防除剤の材料は、安全性が高く、入手も容易であるため、安全かつ安価な害虫防除剤を提供することができる。
さらに、この害虫防除剤は、土壌処理と木部処理の双方に適用できるため、現場での施工を容易に、効率よく行うことができる。
In the present invention, by combining a surfactant and a rust preventive agent with calcium chloride, the spreadability of calcium chloride is enhanced and a high control effect is obtained, and there is no problem of metal corrosiveness with respect to a metal member under the floor. A pest control agent can be obtained.
Furthermore, by using a sulfate or alginate, such as calcium sulfate, barium sulfate, or sodium alginate, a synergistic effect can be obtained by increasing the contact time between the pest and calcium chloride, and a remarkably high control effect can be obtained. Can do. As a result, it exhibits a high insecticidal effect against various termites including not only Yamato termites but also termites, and can effectively prevent houses.
Moreover, since the material of the pest control agent according to the present invention is highly safe and easily available, a safe and inexpensive pest control agent can be provided.
Furthermore, since this pest control agent can be applied to both soil treatment and xylem treatment, construction at the site can be performed easily and efficiently.
以下に、本発明の好ましい実施形態について説明するが、本発明はこれらの実施形態に限定されることはない。
塩化カルシウムは、無水塩でも含水塩（１〜６水塩）でも、どちらも用いることができる。
Hereinafter, preferred embodiments of the present invention will be described, but the present invention is not limited to these embodiments.
As calcium chloride, either an anhydrous salt or a hydrated salt (1 to 6 hydrate) can be used.
塩化カルシウムの配合量は、害虫の種類に応じて適宜設定すればよいが、一般には１０〜５０重量％であることが好ましく、１５〜４５重量％であることがより好ましく、２０〜４０重量％であることがさらに好ましく、２５〜３５重量％以上あることが一層好ましい。塩化カルシウムを５０％より多く配合しても飽和溶液となってしまうため、さらなる効果の向上はみられない。一方、１０重量％に満たない場合は、特にシロアリに対しては、十分な防除効果が得られない恐れがある。 The blending amount of calcium chloride may be appropriately set according to the kind of pest, but generally it is preferably 10 to 50% by weight, more preferably 15 to 45% by weight, and more preferably 20 to 40% by weight. More preferably, it is more preferably 25 to 35% by weight or more. Even if calcium chloride is added in an amount of more than 50%, it becomes a saturated solution, and thus no further improvement in effect is observed. On the other hand, when it is less than 10% by weight, there is a possibility that a sufficient control effect cannot be obtained particularly for termites.
本発明において、有効成分の木部への浸透性を高めるために、害虫防除剤には界面活性剤が配合される。界面活性剤の種類は特に限定されず、アニオン界面活性剤、非イオン界面活性剤等を使用することができる。なかでも、浸透性、乳化・分散性などの観点から、非イオン界面活性剤が好ましく、ポリオキシエチレンアルキルエーテル、ポリオキシプロピレンアルキルエーテル、ポリオキシエチレンアルキルフェニルエーテル、ポリオキシプロピレンアルキルフェニルエーテル等のエーテル型の非イオン界面活性剤が特に好ましい。 In the present invention, a surfactant is added to the pest control agent in order to increase the penetration of the active ingredient into the xylem. The kind of surfactant is not specifically limited, Anionic surfactant, a nonionic surfactant, etc. can be used. Among these, nonionic surfactants are preferable from the viewpoints of permeability, emulsification / dispersibility, and the like, such as polyoxyethylene alkyl ether, polyoxypropylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxypropylene alkyl phenyl ether, etc. Ether type nonionic surfactants are particularly preferred.
また、環境面への配慮から、生分解性の界面活性剤を使用することが好ましい。生分解性の界面活性剤としては、たとえば、「ＳＣ−Ｍａｇｉｃ Ｐａｎ（マジックパン）」（インフィニティ株式会社）等の市販品を使用することができる。これは、植物性の界面活性剤、脂肪酸およびその他の成分から構成される界面活性剤である。 In consideration of the environment, it is preferable to use a biodegradable surfactant. As the biodegradable surfactant, for example, a commercially available product such as “SC-Magic Pan” (Infinity Co., Ltd.) can be used. This is a surfactant composed of vegetable surfactants, fatty acids and other ingredients.

More preferably it is. Wood processing For, is preferably about 100 to 500 ml / m 2, and more preferably about 200~400ml / m 2.
本発明によるシロアリ防除効果を高めるために、害虫防除剤の散布または塗布の前に、散布または塗布と同時に、あるいは散布または塗布の後に、硫酸塩またはアルギン酸塩、たとえば硫酸カルシウム、硫酸バリウム、またはアルギン酸ナトリウムを散布または塗布することが非常に有効である。これらの薬剤を散布または塗布することにより、物理的な層を形成してシロアリと塩化カルシウムとの接触時間を増やすことで相乗効果が得られ、顕著に高い防除効果を得ることができる。 In order to enhance the termite control effect according to the present invention, a sulfate or alginate such as calcium sulfate, barium sulfate, or alginic acid is applied before, simultaneously with, or after the application or application of the pest control agent. It is very effective to spray or apply sodium. By spraying or applying these agents, a synergistic effect can be obtained by forming a physical layer and increasing the contact time between termites and calcium chloride, and a remarkably high control effect can be obtained.
硫酸カルシウム、硫酸バリウム、またはアルギン酸ナトリウムの添加量または処理量は、特に限定されず、その有効成分の濃度や適用箇所により適宜設定すればよい。 The addition amount or treatment amount of calcium sulfate, barium sulfate, or sodium alginate is not particularly limited, and may be set as appropriate depending on the concentration of the active ingredient and the application location.
以下、本発明に係る害虫防除剤の効果を、シロアリを対象とする土壌貫通試験および木材食害試験により確認した。
＜土壌貫通試験＞
直径１．８ｃｍの円筒に植壌土を４ｃｍの高さに詰め、上部から処理量５Ｌ／ｍ２の試験液をしみこませた。風乾後、２．５ｍｌの水で土壌を適度にしめらせた後、円筒の一端に松の木粉の入った容器を、他端にイエシロアリの職蟻４０頭を入れた。４日後までのシロアリによる土壌の穿孔の程度（穿孔長）とシロアリの死虫数を調べた。
Hereinafter, the effect of the pest control agent according to the present invention was confirmed by a soil penetration test and a wood eating damage test for termites.
<Soil penetration test>
A 1.8 cm diameter cylinder was filled with planting soil to a height of 4 cm, and a test solution with a treatment amount of 5 L / m 2 was soaked from above. After air drying, the soil was moderated with 2.5 ml of water, and then a container containing pine wood flour was placed at one end of the cylinder, and 40 termite ants were placed at the other end. The degree of soil perforation by the termites (perforation length) and the number of termite dead insects until 4 days later were examined.
＜防錆試験＞
試験液２５ｍｌを５０ｍｌ蓋付ガラス瓶に入れ、鉄製テストピース（ＳＳ−４００、４０ｍｍ×２０ｍｍ×２ｍｍ）を浸漬後、密閉し４０℃、３０日間恒温機内で静置した。その後、テストピースを取り出し、錆の発生程度を観察した。
<Rust prevention test>
25 ml of the test solution was placed in a 50 ml glass bottle with a lid, an iron test piece (SS-400, 40 mm × 20 mm × 2 mm) was immersed, sealed, and left in a thermostatic oven at 40 ° C. for 30 days. Then, the test piece was taken out and the degree of rust generation was observed.

得られた結果を表２〜４に示す。
<Examples 1-5, Comparative Examples 1-2>
Test solutions for each Example and Comparative Example shown in Table 1 were prepared. The components of the test solution shown in Table 1 are as follows.
Calcium chloride: Reagent made by Iki Kasei Co., Ltd. (CaCl2)
Surfactant: Polyoxyethylene alkyl ether (“Pelesoft NSC” manufactured by Miyoshi Oil & Fat Co., Ltd.)
Antirust agent: Polyoxyethylene alkylamine (Miyoshi Oil Co., Ltd. “Muron”)
Adjuvant A: Calcium sulfate: Wako Pure Chemical Industries, Ltd. Reagent (CaSO4)
Auxiliary agent B: Barium sulfate: Wako Pure Chemical Industries, Ltd. Reagent (BaSO4)
Adjuvant C: Sodium alginate: Reagent manufactured by Wako Pure Chemical Industries, Ltd. As a control, soil not treated with the test solution was also tested. There were 3 test zones each.
The obtained results are shown in Tables 2-4.
上記の結果にみるように、実施例の試験液では、非常に高い防除効果が得られた。シロアリに対しては、死虫率が１００％でなければ、実用上耐えることができないことから、これら試験液の有用性は明らかである。補助剤の物理的な層を作る作用により、シロアリと塩化カルシウムとの接触時間を増やすことで相乗効果が得られ、顕著に高い防除効果を得られることが判明した。
これに対し、比較例の試験液では、十分な防除効果が得られなかった。
As can be seen from the above results, the test solution of the example obtained a very high control effect. For termites, the usefulness of these test solutions is clear because they cannot be practically tolerated unless the death rate is 100%. It has been found that a synergistic effect can be obtained by increasing the contact time between termites and calcium chloride by the action of forming a physical layer of the adjuvant, and a remarkably high control effect can be obtained.
On the other hand, with the test solution of the comparative example, a sufficient control effect was not obtained.
