本発明は水性殺虫剤、更に詳しくは水不溶性のピレス
ロイド系殺虫剤を特定の界面活性剤を用いて水中に可溶
化してなる均一透明て安定性の優れた新しい形態の水性
殺虫剤に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is a new, uniformly transparent and highly stable form of an aqueous insecticide, more specifically a water-insoluble pyrethroid insecticide, which is solubilized in water using a specific surfactant. Concerning aqueous insecticides.

所から近時その有用性が注目されている。Aqueous insecticides based on water have recently become useful because they do not pose the risk of ignition and explosion or toxicity to humans and animals, and are inexpensive to produce compared to oil-based insecticides based on organic solvents. Gender is attracting attention.

。However, pyrethroid insecticides are water-insoluble, and it is impossible to stably disperse or emulsify them directly in water. The decomposition of the drug is accelerated by contact with the drug, which has the disadvantage that its originally excellent medicinal efficacy is drastically reduced in a short period of time. Therefore, at present, no aqueous insecticide has been developed which is made by dispersing the above-mentioned pyrethroid insecticide in water and which has excellent storage stability and does not substantially suffer from a decrease in efficacy. In addition, emulsified insecticides that are diluted with water before use have been commercially available, and are considered water-based insecticides in that they exhibit an emulsified state when used, but the emulsified state is still inferior in stability. If the pyrethroid insecticide separates into two layers in a short period of time and is left in an emulsified state after dilution, the efficacy of the pyrethroid insecticide rapidly decreases. As described above, the present invention provides a new aqueous insecticide that has not yet been developed, although its usefulness has been attracting attention as compared to oil-based insecticides. That is, the present invention includes a pyrethroid insecticide of 2.0% by weight or less, a mixed surfactant of the same weight or more as the above-mentioned insecticide and 5% by weight or less, and an aqueous insecticide whose main component is water. If the mixed surfactant is A. H.L.

る。The aqueous insecticide of the present invention successfully disperses or solubilizes a pyrethroid insecticide in water in a uniform and transparent state by using a predetermined amount of the above-mentioned specific mixed surfactant. The solubilized state does not change at all even after a long period of over 6 months. However, the dispersed pyrethroid insecticide does not substantially lose its medicinal efficacy even after a long period of time as described above. On the other hand, when the surfactants mentioned above are used alone or in combinations other than those mentioned above, it is not possible to disperse the pyrethroid insecticide in a solubilized state, and even if it can be uniformly dispersed, only 1. It separates into two layers within a few days, and its medicinal efficacy is greatly reduced.

できる。Each component used must have a specific HLB value, and if the HLB value deviates from the predetermined value, the effect of combined use will be reduced and it will be difficult to achieve the desired solubilization. Of course, solubilization is not possible when the compounds belonging to each component are used alone. Further, the usage ratio of each component constituting the above-mentioned mixed surfactant can be determined as appropriate depending on the type and combination of the components, the type of pyrethroid insecticide, etc. ．． A-C
When using a combination of components A, B and C, it is preferable to mix them in approximately equal weight proportions, preferably in the range of about 30 to 7% by volume and about 70 to 3% by volume, respectively.

とにより調製される。The polyoxyethylene castor oil used as component B is HL.
Any castor oil having 40 to 80 moles of ethylene oxide added thereto so that B is in the range of 12 to 15 can be used. As the polyoxyethylene styrenated phenol nonionic surfactant used as component C, there are various surfactants having an HLB in the range of 12 to 15 and an added mole of ethylene oxide of 10 to 30 moles, similar to the above component B. Can be used. In addition, the surfactant used as component D is the above-mentioned A
- All nonionic surfactants other than component C can be used, but in any case, their I (L and B must be in the range of 12 to 15. Typical examples include polyoxyethylene sorbitan fatty acid Examples include ester, polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene fatty acid ester, etc. The amount of the above pyrethroid insecticide and mixed surfactant used is preferably 2% by weight or less of the pyrethroid insecticide. is 0.01 to 1% by weight, and the mixed surfactant is in the same weight range as the above pyrethroid insecticide to 5% by weight, preferably 3% by weight.The mixed surfactant is preferably pyrethroid within the above range. It is preferable to use the active agent in an amount of 1 to 2 times the weight of the insecticide, preferably 2 to 5 times the weight of the insecticide.If the active agent is less than the same weight as the insecticide, it will be difficult to achieve the desired solubilization. On the other hand, if it exceeds 3% by weight, the desired solubilization may be achieved, but the active agent itself will be too much in the resulting aqueous insecticide, and when used, it may cause phytotoxicity to plants, etc., or produce an irritating odor. The aqueous insecticide of the present invention is prepared by adding the insecticide and activator to water at the above-mentioned predetermined ratios simultaneously or sequentially and mixing and stirring.
