Problems solved by technology

[0005] The inventors found that the drug-soaking body prepared by this method had obvious inhomogeneity in the release rate of the insecticide components, and the release rate of the insecticide showed an obvious gradual downward trend, and even the release rate at the end was less than 50% of the initial release rate; on the other hand, due to the lack of buffer conditions for the release of insecticides, the release rate is greatly affected by external conditions such as temperature, humidity, and wind speed

Embodiment 1

[0032] A pyrethroid release control composition, comprising: 100 parts by weight of transfluthrin; 2 parts by weight of paraffin; and a polyester fiber mesh carrier.

[0033] Preparation method: mix 20g perfluthrin, 0.4g paraffin, and 79.6g D30, heat at 50°C to dissolve the wax completely, put a 65mm×65mm×2mm square polyester fiber mesh into the liquid medicine and soak for 1min Take it out, shake off the excess medicinal solution, control the weight of the medicinal solution immersed in the mesh to about 1 g, and let it air-dry for 8 hours at room temperature to obtain release-controlled composition 1.

Embodiment 2

[0035] A pyrethroid release control composition, comprising: 100 parts by weight of transfluthrin; 60 parts by weight of paraffin; and a polyester fiber mesh carrier.

[0036] Preparation method: Mix 20g of perfluthrin, 12g of paraffin, and 68g of D30, heat at 60°C to dissolve the wax completely, put a 65mm×65mm×2mm square polyester fiber mesh cloth into the liquid for 30s and take it out. Shake off excess medicinal solution, control the weight of the medicinal solution immersed in the mesh to about 1 g, and air-blow for 8 hours at room temperature to obtain Release Controlling Composition 2.

Embodiment 3

[0038] A pyrethroid release control composition, comprising: 100 parts by weight of transfluthrin; 30 parts by weight of carnauba wax; and a polyester fiber mesh carrier.

[0039] Preparation method: Mix 20g of perfluthrin, 6g of carnauba wax, and 74g of D30, heat at 60°C to dissolve the wax completely, put a 65mm×65mm×2mm square polyester fiber mesh into the liquid medicine and soak for 1min Take it out, shake off the excess medicinal solution, control the weight of the medicinal solution immersed in the mesh to about 1 g, and let it air-dry for 8 hours at room temperature to obtain the release-controlling composition 3.

Abstract

The invention provides a pyrethroid release control composition. The pyrethroid release control composition comprises pyrethroid, wax and a carrier, wherein the weight part ratio of pyrethroid to wax is 100 to (2-60), and the steam pressure of pyrethroid is more than or equal to 1x10<-6>Pa at the temperature of 25 DEG C. Under the required condition, the release control composition can further comprise 0.4-120 parts by weight of low volatile solvents. According to the pyrethroid release control composition, the stable release of pyrethroid under the normal temperature condition can be realized, and the pyrethroid release control composition can be used for spatially dispelling pests, in particular to flying pests such as mosquitoes, flies and the like.

Description

technical field [0001] The invention relates to a composition for controlling the release of pyrethroids, which can realize the steady 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] Pyrethroids are a class of broad-spectrum insecticides that can control a variety of pests, and are widely used in the control of sanitary pests, especially the control of flying pests such as mosquitoes and flies. To achieve the effect of continuous space control of pests, pyrethroids need to be continuously released into the air. The usual way is to continuously release pyrethroids for a certain period of time under heating conditions, such as coiled mosquito coils, electric mosquito coils, and electric mosquito coils. It is this type, but because these products need to release pyrethroids under high temperature conditions, the energy consumption is high ...
