Abstract
Description
本発明は、シロアリ駆除・防除のためのシロアリ駆除組成物およびシロアリ防除方法に関する。 The present invention relates to a termite control composition and a termite control method for controlling and controlling termites.
現在、主に実用化されているシロアリ駆除法としては、カーバメート系化合物、ピレスロイド系化合物等の殺虫活性成分を含有する製剤をシロアリで被害を受けた箇所やシロアリが家屋に侵入する箇所等に散布する方法およびベンゾイルウレア系化合物等の昆虫成長制御剤を餌に混入してシロアリに摂食させてシロアリ駆除を行うベイト工法が挙げられる。後者のベイト工法では、限定的に薬剤を使用するので環境を汚染しないという長所がある反面、シロアリを駆除するのに2,3か月もかかるという欠点があった。 Currently, the termite control methods that are currently in practical use include spraying formulations containing insecticidal active ingredients such as carbamate compounds and pyrethroid compounds to places where termites are damaged or where termites enter homes. And a bait method in which an insect growth control agent such as a benzoylurea compound is mixed in the bait and fed to termites to control termites. The latter bait method has the advantage that it does not pollute the environment because it uses chemicals on a limited basis, but it has the disadvantage that it takes a few months to remove termites.
近年、殺虫活性成分をシロアリ巣の中枢に効率よく運搬させる方法として、擬似卵運搬によるシロアリ駆除法(以下、本シロアリ駆除法という)が開示されており、本シロアリ駆除法に適用するためのシロアリ駆除組成物が開示されている。これによれば、擬似卵の運搬を阻害しない範囲でピレスロイド化合物、有機リン化合物、カーバメート化合物等の殺虫活性成分を使用できると記載されている。しかしながら、実際に適用できる殺虫活性成分については、具体的にどのような殺虫活性成分が適するのか、またその薬量範囲についても明らかにされていなかった。 In recent years, a termite extermination method (hereinafter referred to as this termite extermination method) by means of simulated egg transportation has been disclosed as a method for efficiently transporting an insecticidal active ingredient to the center of the termite nest, and this termite is applied to this termite extermination method. A disinfecting composition is disclosed. According to this, it is described that an insecticidal active ingredient such as a pyrethroid compound, an organophosphorus compound, and a carbamate compound can be used within a range that does not inhibit the transportation of a pseudo egg. However, as for the insecticidal active ingredient that can be actually applied, it has not been clarified what kind of insecticidal active ingredient is suitable and its dosage range.
本シロアリ駆除法に用いられる擬似卵の基材に塗布または含有するシロアリ駆除組成物、その薬量範囲および当該シロアリ駆除組成物を用いてシロアリを防除する方法を提供することが本発明の課題である。 It is an object of the present invention to provide a termite-controlling composition applied to or contained in a pseudo-egg base material used in this termite-controlling method, a dosage range thereof, and a method for controlling termites using the termite-controlling composition. is there.

Examples of such a solvent include water, N, N-dimethylformamide, glycol solvents such as ethanol, methanol, and glycerin, and silicone solvents such as silicone oil. Any solvent that does not hinder it may be used.
擬似卵の運搬を阻害させない特殊な製剤としては、乳剤、水性乳剤、活性成分の微粉末や微粒子分を分散剤や増粘剤等で水中に分散させた水性懸濁剤、微粒子や微粉末を溶剤で溶解させて、ウレタン等の高分子樹脂で有効成分を包み込み、その粒子を分散剤、増粘剤等を配合させて水中に分散させるマイクロカプセル製剤等が挙げられる。 Special preparations that do not impede the transportation of mimetic eggs include emulsions, aqueous emulsions, aqueous suspensions in which fine powders and fine particles of active ingredients are dispersed in water with dispersants and thickeners, fine particles and fine powders. Examples include a microcapsule formulation in which an active ingredient is wrapped with a polymer resin such as urethane after being dissolved in a solvent, and the particles are mixed with a dispersant, a thickener, and the like and dispersed in water.
