Embodiment 1

[0010] Embodiment 1: 10% fenprole oil

[0011] At room temperature, 2.4 grams of calcium dodecylbenzenesulfonate, 4.8 grams of alkylphenol polyoxyethylene ether and 4.8 grams of castor oil polyoxyethylene ether were fully mixed to prepare 12 grams of emulsifier; The former drug, 10 grams of cosolvent N-methylpyrrolidone, and the above-mentioned 12 grams of emulsifiers are fully mixed together to form an oil phase. With a high-speed shearing machine, 68 grams of solvent castor oil are slowly mixed at 800 rpm while stirring. Add it into the oil phase, gradually increase the rotation speed to 3000rpm, and stir until it becomes transparent to obtain 10% fenprole oil.

Embodiment 2

[0012] Embodiment 2: 5% tetraprole oil

[0013] At room temperature, 1.6 grams of calcium dodecylbenzenesulfonate, 3.2 grams of alkylphenol polyoxyethylene ether, and 3.2 grams of castor oil polyoxyethylene ether were fully mixed to prepare 8 grams of emulsifiers; The former drug, 4 grams of cosolvent N-methylpyrrolidone, and the above-mentioned 8 grams of emulsifiers are fully mixed together to form an oil phase. With a high-speed shearing machine, 83 grams of solvent castor oil are slowly mixed at 800 rpm while stirring. Add it into the oil phase, gradually increase the rotation speed to 3000rpm, and stir until it becomes transparent to obtain 5% fenprole oil.

[0014] The quality detection index of 5% fenprole oil agent of the present invention is as follows:

[0015]

[0016] 10% fenpronil oil agent of the present invention is as follows to the laboratory bioassay test of locust:

[0017] Before the test, the pressure of the Potter spray tower was stabilized at 100kPa...

Abstract

The invention discloses a flufiprole oily agent and a preparation method thereof. The flufiprole oily agent is characterized by being prepared from the following components by weight percent: 10% of flufiprole raw medicine, 10% of cosolvent, 12% of emulsifying agent and 68% of solvent. The preparation method comprises the following steps: mixing calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene and castor-oil polyoxyethylene ether into the emulsifying agent, then mixing the flufiprole raw medicine, the cosolvent and the emulsifying agent together, carrying out high-speed shearing, slowly adding the solvent into an oil phase at low speed, gradually increasing the rotating speed to high speed and thus obtaining 10% of flufiprole oily agent. The flufiprole oily agent not only can be used for carrying out conventional field spraying, but also is applicable to ultra-low-volume large-area spraying of an airplane, can be used for preventing and controlling insecticide damage at wide areas such as grasslands, has no pollution to the environment and no killing effect for natural enemies of locusts, and has no injury effect for humans and livestock.

Description

technical field [0001] The invention relates to an insecticide, in particular to an oil agent for controlling locusts, and a preparation method thereof. Background technique [0002] Chinpronil is a new type of substituted phenylpyrazole insecticide. It has high insecticidal activity and wide insecticidal spectrum. The main mechanism of action is to hinder the fluoride metabolism controlled by insect γ-aminobutyric acid. , flies and coleopteran pests have high insecticidal activity, and the drug effect lasts for a long time. It is safe for humans and animals and has no mutagenic effect on mouse germ cells. It is ideal for vegetables, fruit trees, fields and other crops. Insecticidal effect, at present, there is no registered dosage form of tetraprole in the control of locusts. [0003] At present, the chemical agents registered for locust control mainly include malathion, imidacloprid, lambda-cyhalothrin, and flubenzuron; the biological pesticides include Beauveria bassiana...
