Embodiment Construction

[0019] In order to make those skilled in the art understand the production process and technical effects of the present invention in detail, the application and technical effects of the present invention will be further introduced below with specific production examples.

[0020] Embodiment 1-5 operating steps: according to the proportioning of each component by weight, the long-acting insecticidal composition is prepared according to the following steps: S1. , earthworm antimicrobial peptide and polyhexamethyleneguanidine phosphate are mixed into carboxybetaine and edible alcohol, and mixed and stirred at 0-40°C to obtain a mixed solution;

[0021] S2. place the mixed solution in an autoclave, add the nitrogen gas boosted by the high-pressure diaphragm pump into the autoclave, heat up and stir to form a suspension;

[0022] S3. The suspension is sprayed and impacted by at least one pair of nozzles placed coaxially opposite each other, and the precipitated coated microcapsule ...

Abstract

The invention provides a long-acting pest-killing composition. The long-acting pest-killing composition is characterized by being prepared from, by weight, 25-35 parts of pyrethroids, 15-25 parts of nanometer silicon carbide hollow microspheres, 10-16 parts of earthworm antimicrobial peptides, 3-7 parts of polyhexamethyleneguanidine phosphate, 6-13 parts of carboxylic glycine betaine and 40-65 parts of edible alcohol. By means of the long-acting pest-killing composition, it can be achieved that the pyrethroids are smoothly released at the room temperature, and with the combination of plant ingredients, the safety is further improved; the long-acting pest-killing composition is used for spatially expelling and killing pests, and a good pest-killing effect especially on flying pests is achieved for control.

Description

technical field [0001] The invention relates to a long-acting insecticidal composition, which can realize the stable release of pyrethroids under normal temperature conditions, and is used for repelling and killing insects in space, especially for the control of flying pests. Background technique [0002] Household hygienic insecticides have a long history. Thousands of years ago, there were records in China of using various natural plants and minerals to drive away and kill mosquitoes. After thousands of years of evolution, mosquito coils, electric mosquito coils, liquid mosquito coils, aerosols, and sprays are now widely used in the prevention and control of mosquitoes. The drug structure of these insecticides has also undergone several changes. With the successful development and wide application of pyrethroids, this type of high-efficiency, low-toxicity, and safe hygiene drugs has gradually replaced Basa, which is harmful to humans, animals and the environment. Wait for...
