At present, China has established a national standard for 197 pesticide residue limits (MRLs) covering 32 different pesticides across 32 types of agricultural and sideline products. These standards are particularly important for fruit crops, where strict control is necessary to ensure food safety. The maximum allowable levels of pesticide residues on fruits are as follows (note: mg/kg = milligrams per kilogram):
1. Chlorothalonil ≤ 1 mg/kg
2. Fenthion ≤ 0.05 mg/kg
3. Phenbutyltin ≤ 5 mg/kg
4. Glyphosate ≤ 0.1 mg/kg
5. Diflubenzuron ≤ 1 mg/kg
6. Mancozeb ≤ 3 mg/kg (for pears)
7. Mancozeb ≤ 5 mg/kg (for small fruits)
8. DDT ≤ 0.1 mg/kg
9. Trichlorfon ≤ 0.1 mg/kg
10. Chlorpyrifos ≤ 1 mg/kg (for pears)
11. Parathion – not detectable
12. Carbendazim ≤ 0.5 mg/kg
13. Diazinon ≤ 0.5 mg/kg
14. Fenvalerate ≤ 0.5 mg/kg
15. Phorate – not detectable
16. Carbaryl ≤ 2.5 mg/kg
17. Metalaxyl ≤ 1 mg/kg (for small fruits)
18. Pirimicarb ≤ 2.5 mg/kg
19. Captan ≤ 15 mg/kg
20. Dimethoate ≤ 1 mg/kg
21. Hexachlorocyclohexane (HCH) ≤ 0.2 mg/kg
22. Cyhalothrin ≤ 0.2 mg/kg (for pears)
23. Permethrin ≤ 2 mg/kg
24. Malathion – not detectable
25. Fenvalerate ≤ 0.2 mg/kg
26. Acetylene ≤ 5 mg/kg (for pears)
27. Thiacloprid ≤ 0.5 mg/kg (for pears)
28. Triazolone ≤ 0.2 mg/kg
29. Triadimefon ≤ 2 mg/kg (for pears)
30. Chlorpyrifos ≤ 0.5 mg/kg
31. Double hyperthyroidism – this term might be a mistranslation; it could refer to a specific compound or a misstatement in the original text
32. Tetramethylazine ≤ 1 mg/kg
33. Phoxim ≤ 0.05 mg/kg
34. Bromoxynil ≤ 5 mg/kg (for pruned fruits)
35. Deltamethrin ≤ 0.1 mg/kg (for edible skin)
36. Imipenem ≤ 0.5 mg/kg
37. Acephate ≤ 0.5 mg/kg
38. Iprodione ≤ 10 mg/kg (for pears)
39. Dichlorvos ≤ 0.2 mg/kg
These regulations reflect the country’s efforts to regulate pesticide use and protect consumer health. Farmers and producers are encouraged to follow these guidelines closely to avoid exceeding the permissible levels. Regular monitoring and testing are essential to ensure compliance and maintain the quality of agricultural products.
