Problems solved by technology

Although the main component contained in these cinnamon essential oils is cinnamaldehyde as described in JP-A-6-286104, aldehyde compounds generally lack stability and are easily oxidized, thereby changing the chemical structure and losing their chemical properties.
Therefore, even if the pest repellent containing plant essential oils mainly composed of aldehyde repelling components is spread in places where pests are produced indoors and outdoors, the repellent components are easily oxidized and denatured due to the influence of light and oxygen in the air. , it cannot be said that the effect as a repellent, but its persistence is a satisfactory pest repellent
These essential oil components are artificially extracted from the bark, leaves, seeds, roots, etc. of plants by methods such as steam distillation and solvent extraction. During these extraction processes, aldehyde components, because of their part It is oxidized and denatured, so the repelling components contained in the plant cannot be effectively and efficiently used as active ingredients of pest repellents

Embodiment 1

[0027] 0.4 parts by weight of cyfluthrin are fully dissolved in 3.0 parts by weight of tripropylene glycol to form a solution, 0.2 parts by weight of cinnamon powder is mixed in the solution, and then 96.4 parts by weight of kaolin is further added, pulverized and mixed with a mixer to obtain The pest control powder of the present invention. 10.0 g of this powder was mixed into 755.0 g of commercially available river sand, stirred well, and then 75.5 g of it was evenly sprinkled in a petri dish made of nitrous. A resin cylinder with an inner diameter of 8 cm and a height of 7 cm was installed in the center portion where the sand was sprinkled, and 20 Japanese mountain ants caught from the wild were placed in the cylinder. After 10 minutes, the inside of the installed tube was observed, and all Japanese mountain ants escaped, confirming that the pest control powder of the present invention has a high control effect.

Embodiment 2

[0029] Based on Example 1, various powders for controlling crawling pests shown in Table 1 were prepared, and a control effect test was performed. The results are shown in Table 1 together. TPG in the table represents tripropylene glycol used as a solvent. In addition, DPG also represents dipropylene glycol. Put 20 individuals of Japanese mountain ants into the cylinder, observe the inside of the cylinder after 10 minutes, and evaluate the results of the effect test with the following criteria.

[0030] ++: All individuals in the cylinder flee.

[0031] +: 5-10 individuals are wandering in the cylinder.

[0032] -: Individuals placed in the cylinder are all wandering in the cylinder.

[0033] 【Table 1】

Abstract

The subject of the invention is to provide a powder for notable preventing and killing crawl pests as follows, which is prepared by adding cyfluthrin as a dimethrin kind of components for preventing and killing crawl pests into mineral substance carriers. The invention provides the powder for notable preventing and killing crawl pests to solve the problems. The powder for notable preventing and killing crawl pests is characterized in that: the mineral substance carriers contains cyfluthrin as components for preventing and killing crawl pests with a total amounts of 0.1 to 0.5 wt.%, ground cinnamon as lustrating components for crawl pests with total amounts of 0.05 to 1.0 wt.%, and dipropylene glycol and / or tripropylene glycol with total amounts of 1.0 to 9.0 wt.% relative to the total amounts of the powder.

Description

technical field [0001] The present invention relates to a powder for controlling pests, and specifically relates to the improvement of the control effect of cyfluthrin powder. Background technique [0002] For a long time, powders containing pyrethroid insecticidal ingredients in mineral carriers have been widely used for indoor and outdoor pest control. Powder is an easy-to-use dosage form. On the other hand, pyrethroid insecticidal ingredients are easily decomposed due to the surface activity of the mineral carrier. Therefore, the stabilization of the formulation is a subject that often needs to be studied. For example, in Japanese Patent Laid-Open No. 63-290803, it is disclosed that "a stable pesticide solid formulation is mixed with at least one compound having a polyoxyethylene group in the following solid formulation, and the solid formulation contains It is formed by synthesizing pyrethroids and organophosphate compounds with benzyl esters with cyano groups at the α ...
