preparation example Construction

[0019] A preparation method for pyrethroids (fenvalerate solution), comprising the following steps:

[0020] (1), accurately take each component by the mass percentage described in claim 1 for subsequent use;

[0021] (2), accurately weighed ethyl acetate and fenvalerate are poured into the batching tank successively;

[0022] (3) After the esfenvalerate is completely dissolved, add accurately weighed Tween 80 and Span 80, constant volume with absolute ethanol, and fully stir for 30 minutes.

[0023] A kind of pyrethroid medicine (fenvalerate solution) and preparation method thereof provided above have the following advantages:

[0024] (1) The pyrethroid drug (fenvalerate solution) provided by the present invention has a reasonable proportion, good stability, convenient use, low toxicity, high efficiency and safety, and reduces the risk of environmental pollution and drug residue caused by other drugs ;

[0025] (2), the pyrethroid medicine (fenvalerate solution) provided ...

Embodiment 1

[0028] ①. Accurately weigh 10kg of ethyl acetate and 20kg of fenvalerate and pour them into a mixing tank until the fenvalerate is completely dissolved.

[0029] ②. Accurately weigh 1 kg of Tween 80 and 1 kg of Span 80, pour them into a mixing tank, use absolute ethanol to make up to 100 L, and stir thoroughly for 30 minutes to obtain the product.

Abstract

The invention relates to the technical field of livestock pesticides, and discloses a pyrethroid pesticide (fenvalerate solution). Each 100 L of the pyrethroid pesticide (fenvalerate solution) comprises the following components in percentage by mass: 20% of fenvalerate, 10% of ethyl acetate, 1% of Tween 80, 1% of span 80 and the balance of anhydrous ethanol for filling. The pyrethroid pesticide (fenvalerate solution) and the preparation method thereof have the following advantages: (1) the pesticide has reasonable proportioning and good stability, is convenient to use, low in toxicity, efficient and safe and reduces environmental pollution caused by other pesticides and pesticide residue risks; (2) the pesticide has good killing effect on various ectoparasites and bloodsucking insects suchas mites, lice, fleas, ticks, mosquitoes, flies and horseflies, of livestock and poultry, the insecticidal power is strong, and effect is definite; (3) the pesticide can also be used for killing sanitary insects, such as mosquitoes, flies and cockroaches in the environment, livestock and poultry sheds and the like.

Description

technical field [0001] The invention relates to the technical field of poultry insecticides, in particular to a pyrethroid drug (fenvalerate solution) and a preparation method thereof. Background technique [0002] With the rapid development of the poultry industry, the country pays more and more attention to people's health, the country's monitoring of animal drug use is becoming more and more strict, and the requirements for drug residues are getting higher and higher. Like the previous organochlorine pesticides and organic Phosphorus pesticides and other pesticides have many disadvantages. Because of their high toxicity, environmental pollution, and long-term drug residues in animals, these pesticides are used less and less, and now the mainstream is pyrethroids. Pesticides are characterized by high efficiency, broad spectrum, low toxicity, high efficiency and safety, no residue and no pollution to the environment. [0003] This product has a good killing effect on vario...
