Pesticides can be classified in the following ways:
According to the mode of action, they can be classified into: stomach poisons, contact poisons, fumigants, and systemic insecticides; according to toxicological effects, they can be classified into: nerve agents, respiratory poisons, physical poisons, and specific insecticides; according to sources, they can be classified into: inorganic and mineral insecticides, botanical insecticides, organic synthetic insecticides, and insect hormone insecticides;
According to chemical structure, they can be classified into: neonicotinoid insecticides, such as imidacloprid and acetamiprid etc.; organophosphorus insecticides, such as phoxim, chlorpyrifos, etc.; carbamate insecticides, such as isoprocarb, methomyl, etc.; pyrethroid insecticides, such as cypermethrin, cypermethrin, etc.; organochlorine insecticides, such as thiosulfan, etc.; acaricide insecticides, such as pyridaben, propargite, etc.; insect growth regulator insecticides, such as fenbuconazole, fenvalerate, etc.; nereis toxin insecticides, such as carbofuran, dimethoate, etc.; benzoylurea insecticides, such as diflubenzuron, buprofezin, etc. In addition, there are plant-based insecticides classified according to the source of active ingredients, such as rotenone, nicotine, etc.; microbial-based insecticides, such as BT, polyhedrosis virus, etc. Let's introduce them in detail according to the chemical structure classification!
Neonicotinoid insecticides
1. Imidacloprid: It has excellent systemic absorption, high efficiency, broad insecticidal spectrum, long lasting effect, and low toxicity to mammals. It also has good root systemic activity, stomach poison and contact killing. Imidacloprid is a systemic insecticide used to control piercing-sucking mouthparts pests such as aphids, leafhoppers, planthoppers, whiteflies, thrips, etc. It can be used for stem and leaf treatment, seed treatment, and soil treatment.
2. Acetamiprid: It has the characteristics of strong systemicity, small dosage, fast effect, high activity, long lasting effect, and wide insecticide spectrum. It is used to control homoptera, lepidoptera, and coleoptera pests of crops such as vegetables, fruit trees, potatoes, and tobacco. It also has obvious preventive effects on beetle pests and has excellent egg and larval killing activity. It can be used for stem and leaf treatment and soil treatment.
3. Thiamethoxam: It has contact killing, stomach poison, and systemic activity, and has higher activity, better safety, a wider insecticide spectrum, fast action speed, and long lasting effect. It has high activity against Coleoptera, Diptera, Lepidoptera, especially Homoptera pests, and can effectively control various aphids, leafhoppers, planthoppers, whiteflies, potato beetles, flea beetles, nematodes and other pests and pests resistant to various types of chemical pesticides. It can be used for stem and leaf treatment, seed treatment, and soil treatment. It is widely used in rice crops, beets, rapeseed, potatoes, cotton, beans, fruit trees, peanuts, sunflowers, soybeans, tobacco and citrus.
4. Nitenpyram: It has the characteristics of low toxicity, high efficiency, long residual effect, and excellent systemic and penetrating effects. It has excellent control effects on various aphids, whiteflies, rice leafhoppers and thrips, and also has good activity against pests resistant to traditional insecticides. Suitable crops are rice, vegetables, fruit trees and tea. Stem and leaf treatment, soil treatment.
5. Thiacloprid: It has the characteristics of strong systemicity, small dosage, good quick effect, high activity, long lasting effect, wide insecticidal spectrum, and no cross-resistance with conventional pesticides. It is also effective against Lepidoptera pests such as leafminers and apple moths on apple trees. Stem and leaf treatment, seed treatment.
6. Thiacloprid: It has the characteristics of wide insecticidal spectrum, contact, stomach poison and systemicity. It is mainly used to control Hemiptera, Coleoptera and some Lepidoptera pests on crops such as rice, fruit trees, cotton, tea, turf and ornamental plants. Stem and leaf treatment, soil and seed treatment.
7. Flonicamid: It has the characteristics of strong systemicity, small dosage, high activity, long lasting effect and wide insecticidal spectrum. It is mainly used to control piercing-sucking mouthparts pests such as aphids, leafhoppers, whiteflies, etc. on crops such as fruit trees, cotton, vegetables, potatoes, etc.
