According to the classification of the targeted pests and diseases
they can be divided into insecticides, acaricides, fungicides, nematicides, herbicides, rodenticides and plant growth regulators, etc.
A chemical agent used to control pests.
Moxidectin
Compared with Abamectin, its insecticidal, acaricidal and nematicidal activities have increased by 10 to 100 times, and the insecticidal spectrum has broadened; it mainly has stomachic action and also has contactic action; the pests will undergo irreversible paralysis, stop feeding, and it takes 2 to 4 days before they die; the killing speed is relatively slow; the residual effect lasts for a long time, 10 to 15 days for crops and 15 to 25 days for mites. It has no internal absorption performance for crops, but it can penetrate the epidermal tissue; it has extremely high activity against lepidopteran pests, mites, Coleoptera and Homoptera pests, and thrips, and is not likely to cause pests to develop resistance; it is easily degraded in soil; it is highly safe for all crops in protected areas or at 10 times the recommended dosage; there is a second insecticidal peak after 10 days.

In such cases, the application rate or concentration can be appropriately increased; it is effective against chewing and piercing pests; it has contact and stomachicidal effects, as well as certain fumigative and penetration effects; it has a strong knockdown effect on pests, performing better at higher temperatures; the residual effect is short; it is prone to cause phytotoxicity to some varieties such as sorghum, melons and beans, grapes, cherries, etc., and should be used with caution; it should be discontinued 10 days before harvest.
Imidacloprid
It is applied during the early larval stage. The older the larva, the worse the efficacy; it inhibits chitin synthesis; it has stomachicidal effects and can penetrate the epidermis of insects and eggs to exert its effect, but has no systemic effect; it is sprayed on the upper surface of plant leaves; the efficacy lasts for more than 30 days and is resistant to rain erosion; it is safe to natural enemies and has high activity against lepidopteran larvae and mosquito and fly larvae; it begins to die 3 days after application and reaches the peak of mortality 5 days later; it is ineffective against adult insects.

Thiazinone
Inhibits chitin synthesis and interferes with metabolism； It takes 3-7 days to take effect； It has no direct killing effect on adults， but can shorten their lifespan， reduce the number of eggs laid， and the eggs produced are mostly infertile； It has good control effects on pests of the hemipteran family such as aphids， leafhoppers， scale insects， and mealybugs， as well as pests of the order of Coleoptera such as beetles，蓟mites， and thrips； The drug effect lasts for more than 30 days； It cannot be used by the soil poisoning method； It is not suitable for direct contact with cabbage and radish， otherwise， it will cause phaeomeningeal spots and green leafing and other pesticide damage.
Iprocarb
It has a killing effect by contact, has certain penetration and conduction activity, and is highly effective quickly; it is mainly used for the control of rice leaf hoppers and leaf beetles, and can also treat thrips; it cannot be used together with bentazon and must be spaced more than 10 days apart; this agent causes damage to taro and should not be used.
Ethylene phosphide
It has a wide range of insecticidal effects, has strong knockdown power, mainly through contact and stomach poison effects, has no systemic effect, is very effective against larvae of the Phyllotreta family, and has a certain killing effect on eggs; it is unstable under light and is best used at night or in the evening, with a short residual period; in the soil, the residual period is very long, suitable for the control of underground pests; cucumbers and beans are sensitive to ethylene phosphide and are prone to drug damage; sorghum is sensitive and should not be sprayed for use; in corn fields, only granular formulations can be used for the control of corn borers, and do not spray for the control of aphids, stink bugs, etc.
Carbendazim
It has a wide range of insecticidal effects, has strong knockdown power, mainly through contact and stomach poison effects, has no systemic effect, is very effective against larvae of the Phyllotreta family, and has a certain killing effect on eggs; it is unstable under light and is best used at night or in the evening, with a short residual period; in the soil, the residual period is very long, suitable for the control of underground pests; cucumbers and beans are sensitive to carbendazim and are prone to drug damage; sorghum is sensitive and should not be sprayed for use; corn fields can only use granular formulations to control corn borers, and do not spray for the control of aphids, stink bugs, etc.
Bifenthrin
Insecticide and acaricide; stomachic and contactic; rapid action, long residual effect; several times more active than other pyrethroid pesticides; stop using 4 days before vegetable harvest; more effective at low temperatures, used in spring and autumn.
Dinotefuran
Rapid action; contactic and stomachic effects; also an excellent egg-killing agent and can penetrate the plant and move upward through body fluids.
Phosalone
Contactic and stomachic effects; no systemic action; rapid knockdown, can control soil pests and larvae of lepidopteran pests; easily decomposes upon exposure to light; sensitive to phosalone in melons, beans, sugar beets, and corn; stop using 5 days before harvest.

Poor efficacy against mites and planthoppers; longer residual period; weak penetration, less contamination of fruit interior.

Triflumethrin
Strong contact killing and stomachicidal effect on pests and mites, also repellent effect; effective against Lepidoptera larvae, ineffective against mites; weak penetration, less contamination of fruit surface.

Bacillus thuringiensis
Bacterial; stomach poison, produces bacterial toxin; slow onset; residual effect lasts about 10 days; the higher the temperature, the more the insects feed, the better the effect; larvae of lepidopteran pests such as cabbage caterpillar, small cabbage moth, striped night moth, sugar beet night moth, silver-winged night moth, etc.; effective only above 30℃; use 2-3 days in advance.
Avermectin
Broad-spectrum antibiotic insecticide and acaricide; stomach poison and contact poison, repellent.
Quaternary ethyl aldehyde
Strong attractant; spring and autumn rainy seasons; after sowing or transplanting of seedlings; due to the weak activity of snails at low temperatures (below 1.5℃) or high temperatures (above 35℃), the control effect is affected.
