IRRI Concludes Hands-on Training on Biotic Stress Resistance Evaluation

Los Baños, Laguna, Philippines – A two-week hands-on training program on biotic stress resistance evaluation concluded at the International Rice Research Institute (IRRI) on October 31, 2024, with 19 researchers and scientists from 9 countries including the USA, Italy, Vietnam, India, South Korea, Laos, Cambodia, Indonesia, and the Philippines.

The training aimed to equip participants with practical skills in identifying, collecting, isolating, and evaluating the damage caused by major rice pests and diseases. The immersive program included lectures, laboratory exercises, and field visits, designed to enhance participants’ understanding of resistance evaluation techniques crucial to their research.

Former IRRI Senior Scientist for Plant Pathology Genetics and Biotechnology Division Dr. Casiana Vera Cruz highlighted the importance of resistance strategies for managing diseases and pests. She stated that effective screening protocols are vital for successful resistance programs, especially when collaborating with rice breeders. “Resistance to diseases and pests is one of the most economical, safe, and environmentally friendly methods of managing these challenges,” she explained.

Dr. Hans Bhardwaj, Research Director and Head of IRRI’s Rice Breeding Innovations, underscored the necessity of standardized and harmonized screening protocols. “This course provides the practical skills and knowledge needed to conduct effective evaluations that ensure reliability and consistency across global research efforts.” He also emphasized the value of networking, noting that the professional relationships developed during the course would benefit their future work.

The training featured expert-led sessions on a range of topics, including rice diseases, insect pests, pathogen collection, media preparation, and especially pathogen inoculation and pest infestation techniques. Dr. Van Schepler-Luu, the primary expert for the course, led the program, with invaluable contributions from resource persons across several IRRI groups, including the Plant Pathology and Host Plant Resistance, Entomology, and Biotic Stress Resistance Evaluation Center (BSREC). Participants gained hands-on experience with pathogen isolation, insect nematode rearing, and pest damage evaluation in greenhouse settings.

Participant feedback was highly positive, with many highlighting the practical value of the hands-on training. Ms. Subah Soni, a graduate student researcher from the University of California, Davis, USA, described the course as an “accelerated learning experience” that helped her gain confidence in handling rice pathogens and pests. Ms. Maricel Torres, Assistant Scientist at IRRI, emphasized how the training would help her support farmers in identifying early signs of pests and diseases while applying eco-friendly control methods.

Given the success of this year’s program, the IRRI Education team plans to offer the course again in 2025.
