The nature and use
of pesticides in the field of raw materials for chemical production
1. Introduction

With the continuous development of agricultural production, pesticides play an important role in protecting crops and increasing the yield of agricultural products. Pesticides are a special class of chemicals, and their properties and uses are essential for effective pest control. This article will detail the nature and use of pesticides in the field of chemical production raw materials.

2. the nature of pesticides

1. chemical properties: pesticides usually have a certain toxicity, can affect the nervous system, digestive system or other physiological processes of pests. At the same time, pesticides may have different chemical stability, pH, water solubility and other properties, which affect their effects and methods of use in practical applications.
2. Physical properties: The physical properties of pesticides include boiling point, melting point, vapor pressure, density, etc. These properties are of great significance for the storage, transportation and use of pesticides. For example, pesticides with high vapor pressure are easy to volatilize and need to be sealed; pesticides with high density need to pay special attention to the mixing ratio during the preparation process.

3. the use of pesticides

1. control of agricultural pests: pesticides are widely used in agricultural production, mainly for the prevention and control of various pests, improve the yield and quality of crops. Different types of pesticides for different types of pests, according to the pest's living habits and damage characteristics of the appropriate pesticides.
2. Health pest control: Insecticides can also be used to control health pests, such as mosquitoes, flies, cockroaches, etc. These pests cause distress to human life and may even spread disease. The use of pesticides can effectively control the number of pests and ensure people's quality of life.
3. Stored grain pest control: Pesticides also play an important role in the protection of stored grain. Grain is vulnerable to pests during storage, resulting in a decline in quality or loss of quantity. The use of pesticides can effectively control stored grain pests and ensure the safe storage of food. The development trend of

With the continuous progress of science and technology, the development of pesticides is constantly upgrading. In the future, the development of pesticides will pay more attention to environmental protection, safety and efficiency. The following are some of the development trends of pesticides:

1. Biopesticides: Biopesticides are an environmentally friendly and safe alternative, and their active ingredients are mainly derived from organisms or their metabolites. Biopesticides have less impact on the environment and non-target organisms, and are an important direction for the development of pesticides in the future.
2. Nano-insecticides: Nanotechnology can improve the activity and efficacy of pesticides and reduce the impact on the environment and non-target organisms. The research and application of nano-insecticides is an important development trend in the field of insecticides in the future.
3. Precision pesticide application technology: Precision pesticide application technology can improve the utilization rate and control effect of pesticides, reduce environmental pollution and harm to non-target organisms. In the future, precision pesticide application technology will be more widely used in the field of pesticides.

5. conclusion

insecticides play an important role in the field of chemical production raw materials, and their properties and uses are very important for effective pest control. With the continuous progress of science and technology, the future development of pesticides will pay more attention to environmental protection, safety and efficiency. In practical applications, appropriate pesticides should be selected according to the types and hazard characteristics of pests, and attention should be paid to use methods and safe operations to ensure the safety of agricultural product yield and quality.
