China Funds 232 Research Topics to Develop 3000 More Pesticide MRLs by 2020

China pledged to develop 3000 more statutory pesticide MRLs by the end of 2020. Part of the research will be conducted through a government procurement program, consisting of 232 research topics including new MRL developing, existing MRL amendment and CAC standard transformation, as well as the field trial and development of international MRLs.

China Funds 232 Research Topics to Develop 3000 More Pesticide MRLs by 2020On April 9th, 2020, the Chinese National Pesticide MRL Review Committee announced a government procurement program for pesticide MRL regulation development. Successful tenderers will be required to complete a series of MRL-related research and field trials within the next year.

The program consists of 232 topics:

  • 84 new MRLs will impact 63 pesticides in 36 categories of food commodities.
  • 27 MRLs are designated for amendment
  • 114 MRLs will be subject to evaluation and transformation to aligned with 678 CAC (Codex Alimentarius Commission) MRLs of 81 pesticides
  • 9 are for the development of international MRLs of 9 pesticides in 6 minor crops(Chinese featured commodities)
  • 6 are for the development of testing methods
  • 3 are for the development and revision of follow-up evaluation of existing MRLs and pesticides exempted from development.

Detailed information on the active ingredients and commodities to be researched are summarized as follows:

Procedures for the follow-up evaluation of national statutory MRLs of pesticides

(Exemption lists)

Lists of pesticides exempted from Developing MRLs (Microbial pesticides and other Low-risk pesticides)

In late 2019, China updated the national food safety standard, “GB 2763-2019 Maximum Residue Limits of Pesticides in Foods," and the number of statutory MRLs reached to 7107, exceeding those developed by Codex Alimentarius Commission (CAC standard). MoARA also pledged to have 10,000 statutory MRLs by the end of 2020, and 3000 more MRLs and testing methods will be developed within the next year. Parts of the research works were assigned to private research institutes through the government procurement process.
