This requires the development of pesticide products in the direction of high efficiency, low toxicity, and low residue. Since most of the protected areas provide melons, fruits and vegetables that are out of season and have high economic value, consumers have higher requirements for product safety, while tobacco Pesticide is the main dosage form of the protected area, so its pesticide variety positioning is particularly important, but a prominent contradiction is that not all high-efficiency, low-toxicity, and low-residue pesticide varieties can be made into smoke agents, and some pesticides are inherently It is said that it cannot be used as a smoke agent, which is one of the main reasons restricting the development of smoke agents today.
However, through research, it has been found that although many pesticide varieties are analyzed from the physical and chemical properties, it is difficult to make smoke agents according to the previous point of view, but as long as the preparation is reasonable, they still have strong biological activity after being made into smoke agents. Greatly broadened the scope of screening and opened up a new way for the expansion of smoke agent products
For example, the fungicide cymoxanil is a relatively new-generation product for the prevention and treatment of downy mildew and blight in melons, fruits and vegetables. At present, there are only two varieties registered as smoke agents. It is safer to use; the powdery mildew in the later stage of protecting sweet potato crops is serious, and once it occurs, it is difficult to eradicate it by conventional spraying methods, but tests have show

Abstract
The invention discloses a sterilization and insecticide compound, a smoke agent of the compound and a preparation method of the smoke agent. The smoke agent comprises the following components in parts by weight: 1-42 parts of radix stemonae, 1-23 parts of cinnamon, 1-21 parts of turmeric, 1-25 parts of syzygium aromaticum, 1-37 parts of potassium chlorate, 1-37 parts of nitrate of potash, 1-46 parts of wood flour, 1-34 parts of ammonium chloride, 1-49 parts of talcum powder and 0.2-9 parts of superfine silica powder. The preparation method of the smoke agent comprises the steps of extracting the radix stemonae, the cinnamon, the turmeric and the syzygium aromaticum to obtain an extract, and mixing the extract with the rest of components to obtain the smoke agent. According to the invention, the formula is scientific, the process is simple, and the product has sterilization and insecticide functions and is applicable to prevention and treatment of plant diseases and insect pests of traditional Chinese medicinal materials, grain crops, grain depots, trees, flowers and greenhouse vegetables.
Description
technical field [0001] The invention relates to the technical field of pesticides, in particular to a bactericidal and insecticidal composition, an aerosol and a preparation method thereof. Background technique [0002] At present, the application of smoke agent is mainly concentrated in greenhouses, forestry, sanitary pests, and a small amount is used in mildew prevention and disinfection. Most of the original drugs used in commercial smoke agents on the market are chlorothalonil, procymidone, dichlorvos, and isoprocarb. However, in order to pursue drug efficacy and expand the bactericidal spectrum or insecticidal spectrum, some unregistered agents are targetedly added to the fungicides, and highly toxic organophosphorus original drugs such as methamidophos and carbofuran are added to the insecticides. Variety also accounts for a certain proportion. [0003] In order to meet the market demand, the current product development direction of agricultural smoke agents should...
