Problems solved by technology

[0003] However, there are certain problems in the process of using the phosphine agent. During the release process of the phosphine agent, the drug release is prone to uneven release and the long-term effect of the drug is poor, which affects its insecticidal effect. Therefore, we Proposed a slow release device for drug application and its production process

Embodiment 1

[0029] see Figure 1-3 , this embodiment provides a technical solution: a slow-release device for drug application, including a drug application box 1 and a box cover 2, one end of the shaft seat 3 is arranged on the drug application box 1, and the box cover 2 Connected to the other end of the shaft seat 3, the inner surface of the drug application box 1 is coated with a slow-release material, and the main structure of the present invention is formed by the drug application box 1, the box cover 2 and the slow-release material. Among them, the drug application box 1 and the box cover 2 are connected through the shaft seat 3, and the joint of the drug application box 1 is sealed by the sealant 4. The mouth of the box body 1 is sealed to improve the sealing of the spraying box body 1, and the slow-release material slowly releases phosphine, and the effective insecticidal concentration (≥300ppm) of the released phosphine can reach more than 23 days. It can effectively kill insect...

Embodiment 2

[0046] The production process of the slow-release device for drug application is the same as in Example 1, and the thickness of the box board is 4mm.

Embodiment 3

[0048] The production process of the slow-release device for drug application is the same as in Example 1, and the thickness of the box board is 5mm.

Abstract

The invention discloses a drug application slow-release device and its production process, which comprises a drug application box body and a box cover. One end is connected, and the inner surface of the drug application box is coated with a sustained-release material, and the main structure of the present invention is formed by the drug application box, the box cover and the slow-release material, wherein the drug application box and the box cover pass through the axle seat Connect, and seal the junction of the spraying box with sealant, at the same time, seal the mouth of the spraying box 1 through the cooperation of the sealing assembly and the box cover, so as to improve the sealing of the spraying box The slow-release material slowly releases phosphine, and the effective insecticidal concentration of the released phosphine can reach more than 23 days, which can effectively kill insects, especially for resistant pests and eggs, and has long-term insecticidal properties effect.

Description

technical field [0001] The invention relates to the technical field of insecticide, and its specific field is a slow-release device for pesticide application and its production process. Background technique [0002] According to the FAO report, about 10% of the grain in the world is lost due to stored grain pests. The loss caused by pests in the storage process is close to 4%, and the direct or indirect harmful activities of stored grain pests in warehouses will cause a large amount of nutrients to be lost, reducing the quality and safety of grain use. In the process of grain storage, phosphine agent has many advantages such as convenient use, obvious insecticidal effect, economical application, strong penetration and diffusivity of the agent, less pollution and residue on grain, etc., and is currently the best performance in the world. One of the storage insecticides. It is reported that the amount of stored grains that uses phosphine to control pests in my country accoun...
