2. Imidacloprid

Touch, stomach poisoning and systemic sucking; pest paralysis and death; quick-acting, high control effect within one day, high temperature insecticidal effect; piercing and sucking mouthparts pests; easily absorbed by crops, can be absorbed by the same root, It is mainly used to control aphids.

4. Tebufenozide

Promote molting of lepidopteran larvae; effective for both advanced and young larvae; stop feeding (stomach toxicity) after 6-8 hours, which is more rapid than molting inhibitors, and begin to die after 3 to 4 days; no drug damage, Safe for crops.

5. Diflubenzuron

The drug is used in the first instar larvae stage. The larger the insect age, the worse the control effect. It is safe against natural enemies and has high activity against Lepidoptera and mosquito larvae; it starts to die at 3 days after the drug and reaches the peak of death at 5 days; it is not effective for adults.

6. Thiocyclam hydrogen oxalate

Selective insecticide with contact and stomach action, Control of Lepidoptera, Coleoptera, some Diptera and Thysanoptera.

7. Pymetrozine

It is mainly used to control rice planthoppers on rice, with poor quick effect and increasing resistance, and it has poor effect on certain aphids.

8. Nitenpyram

Mainly used to control aphids, rice planthoppers, etc., with good quick-acting, short-lasting period and increased resistance.

9. Acetamiprid

Touch and stomach poison, it can be affected by aphids, leafhoppers, whiteflies, scale insects, leaf miners in Lepidoptera, small carnivorous insects, coleoptera longhorns, thrips and other pests. It is greatly affected by temperature and has low temperature effects. difference!

10. Buprofezin

11. Azadirachtin

Broad-spectrum insecticide, effective against both sucking and chewing pests. 

12. Bifenthrin

Insecticide and acaricide; stomach poison and contact killing; rapid action, can be used as acaricide and control lepidopteran pests.

13. Chlorpyrifos

Broad-spectrum, stomach toxicity, contact killing and fumigation; good effect on underground pests; effect on lepidoptera, mites and nematodes, sensitive to melon seedlings.

14. Deltamethrin

Contact effect, with gastric toxicity, repellent and antifeedant effects; effective for lepidopteran larvae but ineffective against mites; very weak penetration.

15. Lambda-cyhalothrin

Non-systemic insecticide with contact and stomach action,used to control of a wide spectrum of insect pests, e.g. aphids, Coloradobeetles, thrips, Lepidoptera larvae, Coleoptera larvae and adults, etc., in cereals, hops, ornamentals, potatoes, vegetables, cotton, and other crops. 

16. Cypermethrin

Contact and stomach poison are mainly used to kill underground pests.

17. Bacillus thuringiensis

Biological pesticides, in reality, add hidden ingredients to increase the effect.

18. Abamectin

Broad-spectrum antibiotic insecticides and acaricides; stomach poisoning and contact killing are currently used to control red spiders, leaf rollers, and high concentrations of Chilo suppressalis.

19. Malathion

Non-systemic insecticide and acaricide with contact, stomach, and respiratory action, control Coleoptera, Diptera, Hemiptera, Hymenoptera and Lepidoptera in a wide range of crops, including cotton, pome, soft and stone fruit, potatoes, rice and vegetables. 

20. hexaflumuron

Insecticidal and egg-killing activity, and quick-acting, especially to control cotton bollworm, leaf roller, borer, etc. Now high doses are used to control Chilo suppressalis.
