Regional Project: Southeast Asia


A research project working to improve food security and safety in Cambodia, Indonesia, and the Philippines. The focus is on participatory and collaborative IPM research and education programs with farmers who grow vegetables and other high value crops.

Country Profiles

The IPM Innovation Lab has a presence in three countries in Southeast Asia. These fact sheets provide an overview of the work we are doing in each country, including our research challenges and accomplishments.



This participatory regional project involves farmers, extension workers, NGOs, IARCs, and national research agencies as well as scientists from U.S. universities. Field research is targeted to activities that directly address farmer needs while providing ancillary benefits to the environment, rural communities, and consumers. In conjunction with the field research, social scientists assess IPM systems in terms of economic impacts and changes in the social dynamics of farm communities, including the role of women in agriculture. Integral to the project are the effects of changing women’s roles as IPM systems are implemented.

To enhance the adoption of IPM in vegetable and other crop systems, education activities form the cornerstone of the project.  This training helps to ensure that famers and IPM scientists adopt and propagate viable IPM practices. An additional benefit of this project is the communication between project collaborators in the United States, Philippines, Indonesia, and Cambodia who promote synergistic efforts in IPM across the Southeast Asian region.

In the Philippines, research focuses on IPM for tomato, cucurbits, and eggplant in Laguna and Batangas Provinces. Additional sites include vegetables grown in rice-based systems in Nueva Ecija and the surrounding area.

In Cambodia, IPM research sites are established near Phnom Penh, and in Kampong Cham, Kampong Thom, and Siem Reap Provinces.

In Indonesia, research on vegetable IPM and other crops is extensive. The project has research sites and collaborators centered in North Sulawesi, East Java, West Java, North Sumatra, and Bali.

Project achievements and highlights


  • After only two years, the project has introduced Trichoderma, a beneficial fungus, which in repeated trials has shown significant improvement in crop production for cabbage, bitter gourd, yardlong beans, tomato, eggplant, Chinese cabbage, and cucumber.
  • Two workshops on plant pest diagnostics have been a key part of an effort to build an infrastructure for Cambodian farmers to receive expert assistance with disease and pest problems.


  • Bogor Agricultural University, a leading institution in the country, has six Clemson-trained, Ph.D. faculty members and leads a national IPM research effort focusing on important high-value vegetable and fruit crops.
  • Under this project, working partnerships with research institutions in six major crop areas in the country have been established. These research efforts, coupled with outreach programs for farmers, have improved food security, safety, and income for farmers growing  important vegetable crops and other crops, including coffee, cocoa, and local fruits.
  • Papaya mealybug devastation of Indonesian papaya crops was identified, analyzed, and controlled via IPM efforts initiated by program leaders and local collaborators.


  • Since the project’s inception, over a thousand farmers have been trained in IPM practices for local vegetable crops, including eggplant, onion, garlic, tomatoes, and peppers.
  • Research has focused on identifying local, beneficial organisms in vegetables, applying Trichoderma and VAM in onions, and identifying eggplant lines resistant to fruit and shoot borer.
