We live in a global community and plant diseases do not recognize country borders. Agricultural trade is responsible for movement of a myriad of plant pathogens globally each year. A significant portion of the foods we consume are grown in the tropics and imported into the United States. Students need a global perspective on the plant pathogens that infect our imported food crops.
The International Research Experience for Students (IRES) in Global Plant Health promotes discovery research using hands-on training in the tropics. Plant disease is a limiting factor in agricultural production in many areas of the world. In the humid tropics, diseases are difficult to control due to high rainfall conditions and the presence of a diversity of plant pathogenic microorganisms.
The program is directed by Dr. Jean Ristaino (Department of Plant Pathology) and Dr. Margo Daub (Department of Plant Biology). Requirements for the Global Plant Health Internship program include:
- 1 semester studying tropical plant pathology (PP540), offered in the spring
- 6-week summer research internship in Costa Rica
- 1 special problems research course, offered in the fall.
- Upper-undergraduate or graduate level
Learning objectives of the program include:
- Developing a knowledge base and critical thinking skills on issues related to tropical agriculture, emerging plant diseases, ecology and the environment.
- Identifying trade issues that are important in regulating plant pathogens that are imported from the tropics.
- Identifying and developing appropriate skills for conducting ecologically-based plant pathology research in the tropics.
- Developing an appreciation for the language, culture and people of Costa Rica and the foods they consume and export.
