Embodiment 1

[0009] The present embodiment RIFA contact powder is made up of the following components by weight percentage: fipronil 0.2%, emulsifier 0.1%, white carbon black 12%, kaolin 86.05%, solvent 1.65%, described solvent is acetone, described emulsifying agent The OP series emulsifier is used as the agent, and of course other commonly used emulsifiers can also be used. The solvent is used to dissolve fipronil, and the emulsifier is used to emulsify fipronil and then mix it with white carbon black and kaolin to make powder according to conventional methods. This medicine can be obtained.

Embodiment 2

[0011] The RIFA contact powder of this embodiment is composed of the following components in weight percent: 0.2% fipronil, 0.1% emulsifier, 13% white carbon black, 85% kaolin, and 1.70% solvent, the solvent being xylene. All the other features are the same as in Embodiment 1.

Embodiment 3

[0013] The contact powder of red imported fire ants in this embodiment is composed of the following components in weight percent: 0.2% of fipronil, 0.1% of emulsifier, 12.5% ​​of white carbon black, 85.52% of kaolin, and 1.68% of solvent, and the solvent is dimethylformamide . All the other features are the same as in Embodiment 1.

[0014] The solvent described in the above examples may also be other commonly used solvents such as butanone or glacial acetic acid.

[0015] The active ingredient of the powder of the present invention is fipronil (Fipronil), and its chemical name is (RS)-5-amino-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-trifluoro Methylsulfinylpyrazole-3-carbonitrile is a phenylpyrazole insecticide with a wide insecticidal spectrum. The insect mechanism is to hinder the chloride metabolism controlled by insect γ-aminobutyric acid. It has high insecticidal activity and has no phytotoxicity to crops. This product can not only kill the red fire ants directly co...
