At present, China has established a national standard for 197 pesticide residue limits (MRLs) across 32 different types of agricultural and sideline products. These regulations set maximum allowable levels for various pesticides on fruit crops, ensuring food safety and compliance with international standards. Below are the specific maximum residue limits for some commonly used pesticides on fruit trees (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 should not be detectable
12. Carbendazim ≤ 0.5 mg/kg
13. Diazinon ≤ 0.5 mg/kg
14. Fenvalerate ≤ 0.5 mg/kg
15. Phorate should not be 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. HCH (Hexachlorocyclohexane) ≤ 0.2 mg/kg
22. Cyhalothrin ≤ 0.2 mg/kg (for pears)
23. Permethrin ≤ 2 mg/kg
24. Malathion should not be 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. Triazophos ≤ 2 mg/kg (for pears)
30. Chlorpyrifos ≤ 0.5 mg/kg
31. Double hyperthyroidism – this term may refer to an incorrect or outdated listing; it is advised to consult the latest regulatory documents.
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 standards are regularly updated to reflect new scientific findings and ensure that the pesticide residues in food remain within safe limits. Farmers and producers must strictly follow these guidelines to maintain product quality and consumer health.
