Problems solved by technology
[0007] However, although the preparation stability of the pest repelling powder described in Patent Document 1 is excellent, its stability is only about 2 weeks as described in paragraph [0015]. Therefore, there is still room for further improvement. room
[0008] Here, in order to ensure the long-term stability of more than 2 weeks, it is also considered to increase the compounding amount of the preventive component and the solvent, but there is the following problem: due to the increase in cost, or the inability to form a powder due to too much solvent, it is not possible to simply Increase the amount of compounding
[0009] In addition, in Patent Document 2, although the effect of improving the control performance brought by solvents such as n-paraffins has been confirmed, it cannot meet the requirements in terms of long-term stability beyond 2 weeks.

Embodiment 1
[0036] Fully mix 91.8% by weight of talc in 5.0% by weight of normal paraffin, then add a mixed solution of 0.2% by weight of cyfluthrin and 3.0% by weight of dipropylene glycol, and use a hammer mill to pulverize and mix to obtain the compound of Example 1. Powder for creeping pest control.
Embodiment 2～10
[0038] Except having prepared according to the raw material and compounding quantity shown in Table 1, it operated similarly to Example 1, and obtained the powder agent for creeping pest control of Examples 2-10.
Embodiment 11
[0040] Fully mix 95.1% by weight of talc in 1.5% by weight of n-paraffin, then add a mixed solution of 0.3% by weight of cyfluthrin and 3.0% by weight of tripropylene glycol, add 0.1% by weight of cinnamon powder thereto, and use a hammer mill Machine is pulverized and mixed, obtains the creeping pest control powder of embodiment 11.

The present invention provides a powder used for creeper pest control, and aims at providing a powder used for creeper pest control capable of realizing long-term stability of control performance and realizing further improve of the control performance. The powder used for creeper pest control loads cyfluthrin, aliphatic hydrocarbon solvent and / or aromatic ether solvent, and glycol solvent on a mineral substance carrier, and is characterized in that: a use level of the cyfluthrin is 0.03-1.0% by weight relative to the powder, a use level of the aliphatic hydrocarbon solvent and / or aromatic ether solvent is 0.5-20.0% by weight relative to the powder, and a use level of the glycol solvent is 0.5-9.0% by weight relative to the powder.
Description
technical field [0001] The present invention relates to a powder for controlling creeping pests outdoors or indoors, and more specifically, to a powder for controlling creeping pests capable of improving the long-term stability of the control performance and improving the control performance itself. Background technique [0002] Conventionally, control agents have been used for repelling crawling pests outdoors or indoors, and higher control performance and stability are generally required for these control agents. [0003] Here, the present applicant has already disclosed in Patent Document 1 that by using a solvent such as dipropylene glycol or tripropylene glycol to load a pyrethroid compound as a control component on a mineral carrier such as talc, it is possible to provide a product with excellent formulation stability. Powder for expelling pests. [0004] In addition, for example, Patent Document 2 describes that by using a solvent such as n-paraffin for the purpose o...
