Abstract:

To study the impact of maximum residue limit standards of pesticides on China’s foreign trade of mung bean, we made a comparative analysis between China and its trading countries in terms of the quantity, the size and proportion of the maximum residue limits (MRLs), and the degree of looseness of the limit standards, based on the maximum residue limit standards of pesticides of mung bean established by China, Codex Alimentarius Commission (CAC), the European Union, Japan, the United States, South Korea, Canada and etc. The results show that China’s number of pesticide maximum residue limit standards of mung bean (83 items) is significantly fewer than that of Japan (388 items) and EU (566 items), and also lower than that of CAC (111 items), South Korea (124 items) and the United States (114 items). In addition, China has fewer exemption limit standards and uniform limit standards. The GB 2763-2019 standard only stipulates a list of 44 pesticides that is exempted from establishing the maximum residue limits of pesticides, and does not stipulate the uniform limit standards. Therefore, we need to pay attention to the update of pesticide maximum residue limit standards of relevant trading countries continuously, and combine the pesticide residue data, pesticide degradation data, toxicological data and dietary data to provide technical support for formulating pesticide maximum residue limit standards suitable for China’s mung bean production.

Key words: mung bean, maximum residue limits of pesticides, CAC, European Union, Japan, the United States of America, South Korea, Canada
