There are many varieties of pesticides. So far, there are more than 1,500 kinds of registered countries in the world, of which more than 300 are commonly used. For research and ease of use, pesticides are often classified from different angles. There are many ways to classify it, and the main ones are the following three.
(1) According to the main use, there are insecticides, acaricides, rodenticides, molluscicides, fungicides, nematicides, herbicides, plant growth regulators, and the like.
(2) According to the source classification, it can be divided into three categories: mineral source pesticides (inorganic compounds), biogenic pesticides (natural organic substances, antibiotics, microorganisms) and chemical synthetic pesticides.
(3) There are dozens of chemical structure types of organic synthetic pesticides classified according to chemical structure. The main ones are: organophosphorus (phosphine), carbamate, pyrethroid, organochlorine compounds, organic sulfur compounds, amides. a compound, a urea compound, an ether compound, a phenol compound, a phenoxycarboxylic acid, a triazine, a diazobenzene, a benzoic acid, an anthracene, a triazole, a heterocyclic ring, a coumarin, Organometallic compounds and so on.
