Senior Associate Scientist Nancy Castilla

Nancy is a senior associate scientist at IRRI working in assessing rice crop health and diseases of rice.

Nancy conducts field research on crop health in changing agricultural environments, crop loss assessment, disease management, and disease etiology. She does coordination and organization of knowledge on the biology and management of rice diseases.

Nancy ensures that research linkages with partners in national agricultural research and extension systems (NARES) through technical backstopping, organization of trainings, preparation of training materials, maintenance of database on training materials. She also serves as a resource person on rice fungal diseases and crop health assessment.

Leigh Vial looks at assessing biotic influences (both good and bad) that are taking place as the rice crop approaches its maximum tillering stage. He consults with Nancy Castilla, IRRI plant pathologist, on how to proceed with this assessment, which will take place in the coming days.
