Since the establishment of pesticide registration management system in 1982, China has had a history of more than 30 years of development and improvement. As of December 31, 2012, there were 29631 pesticide registered products in China, 27784 officially registered products and 1348 temporarily registered products. However, because China's current pesticide registration and management system has not yet established a normalized pesticide withdrawal mechanism, most pesticide products only need to be renewed on schedule, and products can be produced and used indefinitely, so it is difficult to actively withdraw. At the recent China Pesticide Import and Export Situation Analysis and Experience Exchange Conference held in Shenzhen, Zong Fulin, Director of the Reevaluation Division of the Pesticide Control Institute, introduced to the participants some ideas and work plans for building the China Pesticide Reevaluation Registration System.

Pesticide reappraisal registration refers to the systematic reappraisal of the effectiveness, safety and economy of pesticides that have been approved, registered, produced and used by applying new scientific evaluation techniques and methods to meet the needs of the constantly developing social economy and various safety standards. It is a common practice for developed countries and regions to strengthen pesticide management to establish a pesticide re-examination system.

A large number of existing registered products are continuously used, and problems such as excessive residue, environmental accumulation and resistance development are particularly prominent; For some registered products, all data are missing and no systematic safety evaluation has been conducted; The problems exposed in the production and use of registered pesticide products have brought great pressure to agricultural production and pesticide market supervision, and also laid huge risks and hidden dangers for pesticide safety management.

Material basis of re-evaluation registration

China has produced and used more than 300 varieties of bulk pesticides throughout the year, with an annual use of 500000 tons, an annual production of more than 3 million tons, and an export volume of 1.6 million tons. Therefore, the existing pesticide production can fully meet the domestic market demand. As the world's largest pesticide production, use and export country, more strict and safe management of registered pesticides will not only have no adverse impact on China's agricultural production and food security, but also greatly reduce the negative pressure of pesticides on the quality and safety of agricultural products and the environment.

Technical support for re-evaluation registration

China implemented the pesticide registration system in 1982, and the registration data requirements were modified three times, adding and improving the evaluation standards and technical indicators of toxicology, environment, residue and other aspects related to food and environmental safety. At the same time, as the chairman of the Codex Alimentarius Commission on Pesticide Residues (CCPR), China has participated in the formulation of international pesticide residue standards, tracked the changes of international pesticide residues, and became familiar with the pesticide residue standard system.

In recent years, China has actively promoted the global joint review of pesticides, and has carried out bilateral and multiple pesticide registration cooperation with the United States, Canada, Australia and other countries, improving the technical level of pesticide risk assessment.

Regulatory support for re-evaluation registration

The newly revised Pesticide Management Regulations strengthen the monitoring and evaluation of the effectiveness and safety of pesticides after registration. So that the cancellation and change of the corresponding pesticide registration certificate can be legally followed.

In addition, many countries around the world have carried out and formulated the management and institutional requirements for pesticide re-registration, which provides reference experience for China. The United States, the European Union, Canada, Mexico, Australia, Japan, South Korea, Thailand and other countries have formulated relevant system requirements according to their pesticide management situation, and have played a great role in ensuring agricultural production, quality and safety of agricultural products, and eliminating backward pesticide varieties and products.

Specific objectives

Through systematic re-evaluation of registered products used for many years in production, a number of varieties and products with high safety risks, poor effects and benefits will be eliminated to ensure agricultural and forestry production, agricultural product quality, ecological environment and human and animal safety. It is planned to select 10-20 varieties with long registration time and large consumption for re-registration evaluation every year from 2014 to 2016. And give full play to the advantages of existing technology reserves, introduce the concepts of risk analysis and control and crop grouping management into the re-evaluation registration management, and guide the applicant enterprises to change the registration management concepts and behaviors. At the same time, we will explore the establishment of pesticide re-evaluation and registration standards that are in line with China's national conditions.

Future key work

First of all, collect the relevant contents of the re-registration work of the United States, the European Union and other countries to understand the main problems and solutions encountered in the process of re-registration. Systematically sort out the situation of registered varieties in China, and combine the national conditions of China to improve the pesticide re-evaluation registration policy and regulations in the pesticide management measures.

Secondly, start the monitoring and operation of pesticide safety accidents in China, and organize the tracking and monitoring of the effectiveness, safety and economy of registered pesticides; Use the online platform to collect and analyze pesticide safety accident information.

According to the registration of pesticide varieties in China, the routine reassessment process plan of registered pesticide varieties is proposed, and the early warning and reassessment of potential risk varieties are launched according to the daily safety monitoring and the comments of the evaluation committee.

The Ministry of Agriculture will also carry out the summary of potential risk pesticide varieties proposed by the temporary and formal registration review committee. Put forward varieties and products that need attention or have risks, do a good job of monitoring, and put forward relevant variety management suggestions. (China Pesticide Network)
