    In recent years, in order to further strengthen the safety management of registered pesticides, while drawing on the pesticide management experience of other countries and combining with China’s national conditions, China has gradually implemented the post-registration safety management concept of pesticides and initiated the re-evaluation of some risky pesticides in batches.
    Achieved certain results
    .
    The progress of pesticide re-evaluation in some developed countries or regions and the re-evaluation and registration of pesticide varieties in China in recent years are now briefly introduced for the reference of industry professionals
    .
    1.
    Progress of pesticide re-evaluation in some developed countries or regions 1.
    1 The United States revised the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) in 1988 to establish a pesticide re-evaluation system
    .
    According to the law, since 1990, the United States has re-registered 1,150 active ingredients (including disinfectants) that were registered before November 1, 1984, and finally retained registration of 384 categories, accounting for 63 of the total number of re-registered varieties.
    %, 229 categories of cancellation of registration, accounting for 37%
    .
    In 1996, the United States promulgated the "Food Quality Protection Act" and revised the "Federal Pesticides, Fungicides, and Rodenticides Act" accordingly, requiring periodic re-evaluation of all registered pesticides for a period of time In 15 years, a pesticide re-registration system with a 15-year cycle has since been established
    .
    Re-evaluation decision (RED) is divided into four situations: cancellation, restriction, revision or continued use
    .
    1.
    2 The European Union and the European Union issued Directive 91/414/EEC in 1991, stipulating that the limited period of registration of registered active ingredients shall not exceed 10 years, and re-registration must be applied for when they expire
    .
    Since 1993, the EU has re-evaluated nearly 1,000 active ingredients on the market.
    The re-evaluation was completed in March 2009.
    As a result, about 250 active ingredients, or 26% of pesticides, were re-registered, and 67% of pesticides had no company.
    Withdrawal from the market due to application, incomplete information, or voluntary withdrawal by the company, and about 70 active ingredients, or 7% of pesticides, were eliminated because they did not meet safety requirements
    .
    In December 2009, the European Union issued Regulation (EC) 1107/2009, which replaced the original Directive 91/414/EEC, stipulating that the re-registration cycle should be adjusted to 15 years.
    Since then, a 15-year re-evaluation system has been established
    .
    At the same time, registration management introduces comparative evaluation and product substitution policies, that is, if there are safer alternatives, the original active ingredient products may not be approved
    .
    1.
    3 Canada Canada revised the PestControl Products Act in 2006, and also established a 15-year re-evaluation system, which has played a huge role in ensuring agricultural production, agricultural product safety and eliminating outdated pesticides
    .
    2.
    Development of pesticide re-evaluation registration in China China’s pesticide re-evaluation registration is in its infancy.
    The current laws and regulations are only reflected in Article 35 of the "Pesticide Management Regulations".
    If serious harm to agriculture, forestry, human and animal safety, and the ecological environment is found in it, after review by the pesticide registration review committee, the agricultural administrative department of the State Council shall announce restriction of use or cancellation of registration"
    .
    Since strict re-evaluation management measures are not formulated in the laws and regulations, pesticide companies have little desire or awareness to adapt to and participate in the re-evaluation work, and lack of awareness of the importance of re-evaluation
    .
    In order to strengthen the safety management of registered pesticides, the Pesticide Inspection Institute of the Ministry of Agriculture has established a special pesticide re-evaluation agency since 2013, which specifically undertakes the establishment of the re-evaluation legal system and the re-evaluation of registered pesticides
    .
    After several years of work, the organization drafted the "Technical Specifications for Pesticide Re-evaluation" and "Methods for Risk Monitoring after Pesticide Registration" and other normative documents
    .
    The monitoring of pesticide use risk has also been strengthened.
    According to statistics, 785 pesticide safety risk incidents have been found, including pesticide resistance, crop safety, residue, environmental and occupational health issues, involving more than 600 pesticides with 137 active ingredients Product
    .
    And carried out the re-evaluation of related risk pesticides.
    Now we briefly introduce the development of the re-evaluation of pesticide varieties in my country in recent years.
