1. Emamectin Benzoate
Compared with abamectin, its insecticidal, acaricidal and nematicidal activity is increased by 10-100 times, and its insecticidal spectrum is broadened. It has mainly stomach poisoning effect and also has contact killing effect. The pests become irreversibly paralyzed, stop eating, and die after 2-4 days. The killing speed is slow. The long-lasting effect is 10-15 days for pests and 15-25 days for mites. It has no systemic properties on crops, but can penetrate into epidermal tissue. It is extremely active against Lepidopteran pests, mites, Coleoptera and Homoptera pests, and thrips, and does not easily cause pests to develop resistance. Easily degraded in soil. Highly safe for all crops in protected areas or at 10 times the recommended dosage. A second insecticide peak occurred more than 10 days ago.
2. Imidacloprid
Nicotinoids; contact poison, stomach poison and systemic inhalation; paralysis and death of pests. It has good quick-acting effect, with a high control effect in one day, and a residual period of about 25 days; it has good insecticidal effect at high temperatures; it has piercing and sucking mouthparts for pests; it is easily absorbed by crops and is distributed to the top, with root sucking effect.
3. Tebufenozide
Promotes lepidopteran larval molting; contrary to other mechanisms that inhibit larval molting. Effective on both older and younger larvae. Stop feeding within 6 to 8 hours (gastric poisoning effect), which acts more quickly than molting inhibitors and begins to die after 3 to 4 days; no phytotoxicity, safe for crops, and no residual drug spots.
4. Chlorobenzuron
Use medication during the first instar larvae stage. The older the insect is, the worse the control effect will be. Inhibits chitin synthesis. It has gastric poisoning effect and can invade the epidermis of insects and eggs, but has no systemic effect. Spray the underside of plant leaves. The drug has an efficacy period of more than 30 days and is resistant to rain erosion; it is safe to natural enemies and highly active against lepidoptera and mosquito and fly larvae; it begins to die 3 days after treatment and reaches the peak of death in 5 days; it is ineffective against adults.
5. Quinalphos
It has insecticidal and acaricidal effects, has gastric poisoning and contact killing effects, and has no systemic or fumigation properties. It has good permeability, has a certain egg-killing effect, degrades quickly on plants, and has a short residual period; it has good effect in preventing chewing and sucking pests.
6. Acetamiprid
Chlorinated nicotine pyridine; contact and gastric poison, good systemic activity; inhibits the activity of acetylcholine receptors. Effectively control various pests such as aphids, leafhoppers, mealybugs, scale insects in the order Hemiptera, leaf miners and small insects in the order Lepidoptera, as well as beetles, thrips and other pests in the order Coleoptera. Granules are used for soil treatment to prevent and control underground pests; they are quick-acting and have a long-lasting effect, up to about 20 days.
7. Buprofezin
Inhibits chitin synthesis and interferes with metabolism. The drug takes 3-7 days to take effect. It has no direct killing effect on adult worms, but it can shorten their lifespan and reduce the number of eggs they lay. Most of the eggs produced are infertile, and the larvae will die quickly even if they hatch. It has good control effect on Hemiptera planthoppers, leafhoppers, whiteflies and scale insect pests, and the efficacy period is as long as more than 30 days. It cannot be used in the poisonous soil method; it is not suitable to come into direct contact with cabbage and radish, otherwise it will cause brown spots, green leaves and other phytotoxicity.
8.Phoxim
It has a broad insecticidal spectrum and strong knockdown power. It mainly has contact and gastric poisoning effects. It has no systemic effect. It is very effective against leptopteran larvae and has a certain killing effect on insect eggs. It is not stable to light and is best used at night or in the evening. It has a short residual period. In the soil, it has a long residual period and is suitable for controlling underground pests. Cucumbers and beans are sensitive to phoxim and are prone to phytotoxicity. Sorghum is sensitive and should not be sprayed. In corn fields, only granules can be used to control corn borers, and sprays should not be used to control aphids, armyworms, etc.
9. Methomyl
It acts quickly; it has contact and gastric poisoning effects. It is also an excellent ovicide and can penetrate into the plant body and move from bottom to top with body fluids.
10. Chlorpyrifos
Broad spectrum, stomach poison, contact kill and fumigation; good effect on underground pests; Coleoptera, Lepidoptera pests and harmful mites; melons are sensitive in seedling stage.
11.Cypermethrin
It has contact killing and gastric poisoning effects, as well as repellent effects, strong knockdown power and fast killing speed; it has special effects on lepidopteran pests and is effective on aphids and small green leafhoppers. It has poor control effect against mites and bugs; it has a long residual period; it has weak penetrating power and causes less internal contamination of fruits.
12.Deltamethrin
It has a contact killing effect and has stomach poisoning, repellent and antifeedant effects; it has special effects on lepidopteran larvae, but is ineffective against mites; its penetration is very weak and only contaminates the peel.
13.Abamectin
Broad-spectrum antibiotic insecticide and acaricide; gastric and contact poison, repellent.
14.Metaldehyde
Strong attraction; spring and autumn rainy seasons; after seedlings are sown or transplanted; low temperature (below 1.5℃) or high temperature (above 35℃) affects the control effect due to weak snail activity.
15.Diafenthiuron
Thiourea is an insecticide and acaricide; used on cotton, fruits, vegetables and tea trees; it has systemic and fumigation effects, and is converted into substances with insecticide and insecticide activity under ultraviolet light. It should be used on sunny days. Resistant aphids, leafhoppers and whiteflies; control damage from diamondback moth, cabbage butterfly and armyworm.
