Pesticides are a class of chemical agents used in agriculture to protect crops from diseases, insects, rodents, and to regulate plant growth and weed removal. In addition to application in agriculture, it is also used in health and epidemic prevention and forestry, animal husbandry, and environmental sanitation. According to the control object, it can be divided into insecticides, fungicides, acaricides, nematicides, rodenticides, herbicides, defoliants, plant growth regulators, and the like. There are more than one thousand varieties of pesticides developed worldwide, most of which are chemically synthesized and a few biologically derived. Pesticides used to control harmful insects are called insecticides. The early insecticides used are mainly biological insecticides (such as pyrethrum, nicotine, etc.) and inorganic compounds. By the 1940s, due to DDT and BHC. The discovery and application have promoted the rapid development of organic pesticides, and organic pesticides such as organic chlorine, organic phosphorus and carbamate have emerged. In addition to being widely used in agriculture, pesticides can also be used in household health and other fields. The use of insecticides is an effective method for controlling pests, but for long-term use, insects develop resistance, which reduces the efficacy and requires replacement of varieties. The pesticides that control various types of crop pathogenic microorganisms are called fungicides. The current fungicides are mainly agents for controlling fungal diseases, and the development of drugs for controlling bacteria and viruses is slow. Rodenticides are used to poison rodents. Early use of acute rodenticides has the disadvantage of being toxic to humans and animals. In recent decades, it has gradually changed to safer chronic rodenticides. Chronic rodenticides are mainly anticoagulation. Pharmacy. Herbicides, also known as herbicides, are used to control weeds in farmland. Plant growth regulators are a class of pesticides that regulate plant growth and development. They are non-nutritive chemicals that promote or inhibit certain aspects of the plant's life processes in a small amount, so that they can be developed in line with human needs.
