North Central Region IR-4 Project


Dr. Jiang has a solid background in science with 20+ years of experience in research, teaching, and services. He has been principal and co-principal investigator on grants and contracts totaling over $8 M. He published and presented over fifty papers and presentations in the areas of chemistry, food safety, environmental contamination, and pest management. Dr. Jiang co-authored over one hundred IR-4 Analytical Summary Reports that have been submitted to the US EPA and AAFC Canada for pesticide tolerance establishment. While being on the USDA Foreign Agricultural Service (FAS) mission Capacity Building, Dr. Jiang and colleagues travelled many countries in Asia, Africa, and Latin America, and helped these developing countries to develop internationally recognized pest management programs and to establish their regulatory systems, which are important to the global food safety. He worked in industries in Toronto and Detroit before joining Michigan State University in 2003. Dr. Jiang became a faculty member at the Department of Entomology in 2006. Dr. Jiang is serving as a senior editor of Bulletin of Environmental Contamination and Toxicology.

Program Description

For more than 50 years, the USDA Interregional Research Project Number 4 (IR-4) Project has been the primary resource in the US for facilitating registrations of pesticides on specialty crops and minor uses which include the majority of fruit, vegetable, and ornamental crops. The IR-4 program is fully funded by USDA. The IR-4 Project contributes more than $7.3 billion to annual GDP in the US. Therefore, IR-4 is important to US specialty crop growers.

Overall my work with IR-4 at MSU is providing the reliable and high quality residue data necessary for tolerance establishment with US EPA. All these studies are conducted under the demanding regulations of EPA’s Good Laboratory Practice (GLP) system. The findings of a new study by the MSU Center for Economic Analysis show that the IR-4 Project contributes to over 95,000 U.S. jobs throughout the agricultural production value chain, generating some $5,632 million in annual labor income, and contribute $9,436 billion to annual gross domestic product (Miller and Mann 2017).

Capacity Building Program of USDA Foreign Agricultural Service helps developing countries improve agricultural systems (such as minor use programs and regulatory systems) and enhances the international trade capacities. Many institutions in the US participate in the Capacity Building program. I have been on the mission of Capacity Building Program for past five years and have been providing the services for the pesticide laboratory GLP training in many countries. I have been the main trainer to pesticide laboratory trainings for Capacity Building studies in the Association of Southeast Asian Nations countries and nearby countries (trainees are from Brunei, Cambodia, Indonesia, Malaysia, Myanmar, Philippines, Singapore, Thailand, Laos, Vietnam, and China, South Korea) , in Africa (Egypt, Ghana, Kenya, Morocco, Senegal, Uganda, and Tanzania), and in Latin America (Costa Rica, Colombia, Argentina). I have been working closely with China to be on the team to foster cooperation and information exchange with intention of a reciprocal recognition of each other’s GLP programs and mutual acceptance of pesticide residue data.
