preparation example Construction

[0015] The present invention also provides a preparation method of the insecticide described in the above technical scheme, comprising the following steps:

[0016] Mix the components at 25-45° C., and stir at 400-600 rpm for 20-40 minutes to obtain the capsaicin-containing insecticide. In the present invention, the components are preferably mixed at 25-45°C, more preferably at 30-40°C, most preferably at 32°C. The setting of the temperature in the present invention can ensure the activity of each component and make the performance of the obtained insecticide more stable. In the present invention, the rotational speed is preferably 450-550 rpm, and the stirring time is more preferably 25-35 minutes, most preferably 30 minutes. The combination of the mixing conditions in the present invention makes the performance of the obtained insecticide stable, and can realize long-term preservation under the environment of 0-55° C., and has a long lasting period.

[0017] In the present...

Embodiment 1

[0026] Take 0.02 parts of capsaicin, 0.05 parts of casein, 0.25 parts of osthole and 10 parts of oleic acid, mix the components at 32°C, and stir at 600 rpm for 35 minutes to obtain a capsaicin-containing insecticide.

Embodiment 2

[0028] Take 0.1 part of capsaicin, 0.02 part of casein, 0.35 part of osthole and 12 parts of oleic acid, mix the components at 28° C., stir at 550 rpm for 30 minutes, and obtain a capsaicin-containing insecticide.

Abstract

The invention relates to a pesticide containing capsaicin, and belongs to the technical field of pesticide preparation. The provided pesticide comprises following components in parts by weight: 0.01 to 0.5 part of capsaicin, 0.02 to 0.06 part of casein, 0.01 to 0.6 part of osthole, and 8 to 15 parts of oleic acid. The provided pesticide is stable, can be stored for a long term at a low / high temperature, has a long acting term and a wide insecticidal spectrum, and barely harms humans and livestock.

Description

technical field [0001] The invention relates to the technical field of pesticide preparation, in particular to a capsaicin-containing pesticide. Background technique [0002] Capsaicin is an extremely pungent vanillyl amide alkaloid extracted from the fruit of capsicum. Capsaicin has complex physiological, biochemical, pharmacological and toxicological biological activities. It can activate the cation channel of the cell membrane, causing a large influx of calcium ions, disrupting the balance of the microenvironment in the body, and causing cell poisoning, such as burning sensation, tingling, itching and Skin flushing, regional hyperemia, and neurogenic inflammatory response. In addition, capsaicin also has a penetrating effect, which can penetrate the cortex, mucous membrane and nail layer of pests, and can be used in traditional insecticide and insect repellent. However, capsaicin-containing insecticides are highly irritating, harmful to humans and animals, and have cert...
