Problems solved by technology

[0002] With the continuous increase of the planting area of ​​my country's protected areas, aerosols have developed rapidly due to their high efficiency, time-saving and labor-saving, and simple use methods. Such problems lead to low smoke formation rate and uneven distribution of the active ingredients of the smoke agent, which will affect the control effect, and seriously cause combustion and explosion accidents, which will cause potential safety hazards and cause huge economic losses.

Abstract

The invention relates to an insecticidal and bactericidal smoke agent. Nitrate, sulfur and a combustion improver are used as raw materials and each component is properly proportioned to finally prepare the insecticidal and bactericidal smoke agent; after the insecticidal and bactericidal smoke agent is ignited, a lot of carbon monoxide, carbon dioxide and sulfur dioxide, even carbon powder and sulfur powder are generated; the fuming temperature is not too high; carbon monoxide and sulfur dioxide have a relatively good killing effect on various insect pests and also has a promotion effect on the growth of plants; therefore, the insecticidal and bactericidal smoke agent provided by the invention is also added with traditional Chinese medicine components with a certain insecticidal effect; the fuming temperature of the insecticidal and bactericidal smoke agent can be controlled within a certain range; the problems in the prior art that the temperature is too high so that properties of added traditional Chinese medicines are changed and the insecticidal effect is influenced are effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of aerosols, and in particular relates to an insecticidal and bactericidal aerosol and a preparation method thereof. Background technique [0002] With the continuous increase of the planting area of ​​my country's protected areas, aerosols have developed rapidly due to their high efficiency, time-saving and labor-saving, and simple use methods. Such problems lead to low smoke formation rate and uneven distribution of the active components of the smoke agent, which in turn affects the control effect, and seriously leads to combustion and explosion accidents, hidden safety hazards, and huge economic losses. Contents of the invention [0003] In order to solve the above problems in the prior art, the present invention provides an insecticidal and bactericidal aerosol and a preparation method thereof. The insecticidal and bactericidal aerosol can produce a large amount of carbon monoxide and sulfur dioxide, an...
