The insecticidal, acaricidal and nematicidal activity of abamectin has been enhanced by 10 to 100 times, and its insecticidal spectrum has broadened. It mainly acts as a stomach poison and also has contact killing effect. The pests will suffer irreversible paralysis and stop feeding, and it takes 2 to 4 days for them to die, so the killing speed is relatively slow. It has a long-lasting effect, with a duration of 10 to 15 days for insects and 15 to 25 days for mites. It has no systemic property in crops but can penetrate the epidermal tissue. It has extremely high activity against Lepidoptera, mites, Coleoptera and Homoptera pests, and thrips, and is less likely to cause pest resistance. It is easily degradable in the soil. It is highly safe for all crops in greenhouses or at 10 times the recommended dosage. There is a second insecticidal peak after 10 days.
Nicotine type; Contact, stomach poison and systemic; Paralyzes and kills pests; Quick-acting; High efficacy is achieved within 1 day, with a residual period of about 25 days; Better insecticidal effect at higher temperatures; Sucking mouthpart pests; Easily absorbed by crops and distributed to the top; Has root absorption effect.
Tebufenozide
Promotes the molting of lepidopteran larvae; operates differently from other mechanisms that inhibit larval molting; effective for both older and younger larvae; stops feeding within 6-8 hours (gastric toxic effect), more rapid than the action of molting inhibitors, and begins to die after 3-4 days; no phytotoxicity, safe for crops, and no residual spots.
Malathion
When the temperature is low, the toxicity decreases. In such cases, the application rate or concentration of the pesticide can be appropriately increased. For pests with chewing mouthparts and piercing-sucking mouthparts; contact and stomachicidal effects, certain fumigation and penetration effects; it has strong knockdown power on pests, and the effect is better at high temperatures; the residual effect period is short; it is prone to cause phytotoxicity to some varieties such as sorghum, melon and bean, pear, grape, and cherry, etc. Therefore, it should be used with caution; it should be stopped 10 days before harvesting.
If the drug is administered during the early larval stage, the larger the larval age, the poorer the control effect will be. ； Inhibits chitin synthesis; gastrotoxic effect, can penetrate the epidermis of insects and eggs to exert its effect, but has no systemic action; sprayed on the back of plant leaves; has a drug efficacy period of more than 30 days, resistant to rain erosion; safe to natural enemies, highly active against lepidopteran larvae and mosquito and fly larvae; begins to die 3 days after application, reaches the peak of death within 5 days; ineffective against adult insects.
Quinalphos
Insecticidal and acaricidal effects, with stomachic and contact killing properties, without systemic and fumigating capabilities; has good penetration ability, has a certain effect on egg killing, degrades rapidly on plants, and has a short residual effect period; has good efficacy in preventing and eliminating chewing and sucking pests.
Acetamiprid
Chlorinated nicotinic pyridine class; Contact and stomachic action, excellent systemic activity; Inhibits the activity of acetylcholine receptors; Effectively controls various pests such as aphids, leafhoppers, scale insects, mealybugs in hemiptera, leaf-eating moths, small pests in lepidoptera, and various pests in diptera like wood-boring beetles, thrips, etc.; Granules can be used for soil treatment to control soil pests; Rapidly effective, with a long residual period of about 20 days.
Buprofezin
Inhibit chitin synthesis and interfere with metabolism; it takes 3 to 7 days to take effect. It has no direct killing effect on adult insects, but it can shorten their lifespan, reduce the number of eggs produced, and the eggs produced are mostly infertile. The larvae even if they hatch will die quickly. It has a good control effect on pests such as planthoppers, leafhoppers, aphids and scale insects. The efficacy period lasts for more than 30 days. It cannot be used by the soil poisoning method; it is not suitable to come into direct contact with cabbage and radish, otherwise, it will cause phytotoxicity such as brown spots and green leafing.
Isoprocarb
Contact killing effect, with certain penetration and conduction activity, and strong efficacy; mainly used for controlling rice leaf hoppers and leaf beetles in rice, and can also treat thrips; cannot be used together with bentazon, a 10-day interval is required; this agent causes damage to taro and must not be used.
Phoxim
The insecticidal spectrum is wide, the knockdown effect is strong. It mainly uses contact killing and stomach poison action, without systemic action. It is very effective against larvae of the Phyllotreta family and has a certain killing effect on insect eggs. It is unstable under light. It is best used at night or in the evening. The residual period is short. In soil, the residual period is very long, suitable for controlling underground pests. Cucumber and bean plants are sensitive to methoxyfenozide and are prone to pesticide damage. Sorghum is sensitive and should not be sprayed for use. In corn fields, only granular preparations can be used to control corn borers, and spraying for aphids, sticky insects, etc. should not be done.
Bifenthrin
Insecticides and acaricides; 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, suitable for use in spring and autumn.
Methomyl
The effect is rapid; it has both contact killing and stomachicidal properties. It is also an excellent egg-killing agent and can penetrate into the plant body, moving upward along the body fluids from the bottom.
Cypermethrin
Contact killing, stomach poisoning effect, and repellent effect. It has strong knockdown power and fast killing speed. It has a specific effect on lepidopteran pests and is effective against aphids and small green leafhoppers. It has poor efficacy against mites and mealybugs; the residual period is longer; the penetrating power is weaker, and it causes less contamination inside the fruit.
Deltamethrin
Contact killing effect, also having stomachicidal, repellent and repellent feeding effects; highly effective against lepidopteran larvae, but ineffective against mites; very weak penetration ability, only contaminating the fruit skin.
Cyfluthrin
Contact killing and stomach poisoning; effective against various lepidopteran larvae; egg killing; repellent effect;
Bacillus thuringiensis
Bacterial; stomach poison, producing bacterial toxins; the efficacy is relatively slow; the residual effect lasts about 10 days; the higher the temperature, the more the insects eat, and the better the effect; larvae of lepidopteran pests such as cabbage caterpillars, small cabbage moths, striped night moths, sugar beet night moths, and silver-striped night moths; the insecticidal effect can only be exerted at temperatures above 30℃; use 2-3 days in advance
Abamectin
Broad-spectrum antibiotic-type insecticides and acaricides; stomachic and contactic, repellent.
Metaldehyde
Strong attraction; Spring and autumn rainy seasons; After sowing or transplanting seedlings; Low temperature (below 1.5℃) or high temperature (above 35℃) due to the weak activity of snails, which affects the control effect.
Diafenthiuron
Thiourea insecticide and acaricide; used on cotton, fruits, vegetables and tea plants; has both systemic and fumigant effects; converts into substances with insecticidal activity under ultraviolet light, suitable for use on sunny days; resistant aphids, big leaf bugs and tobacco aphids, etc.; controls damage caused by small whitefly, cabbage butterfly and night moth.
Diflubenzuron
The chitin synthase is inhibited; this results in sterility of adult insects, and it is toxic to larvae, pupae, adults and eggs; its efficacy in controlling larvae of lepidopteran and dipteran insects is particularly remarkable.
Hexaflumuron
Insecticidal and egg-killing activity, with rapid efficacy, especially for controlling cotton bollworms; it inhibits the feeding speed of various Coleoptera, Diptera, and Hymenoptera insects; has a relatively quick knockdown effect.
