CURRENT PROJECTS
Screening of Acacia koa germplasms for resistance to koa wilt
Koa (Acacia koa Gray) is a keystone species in Hawaii’s forests, valued for its ecological significance and high-quality timber. Infection with koa wilt, caused by Fusarium oxysporum f. sp. koae, has resulted in high mortality rates in both field plantings and native forests. Screening for germplasm with natural resistance to koa wilt is critical to support successful koa reforestation and restoration efforts.
This project is being conducted in collaboration with Nick Dudley and his team at the Hawai'i Agriculture Research Center (HARC).
Survey and management of fungal tomato diseases
Tomato (Solanum lycopersicum L.) is a widely cultivated and consumed vegetable crop worldwide. In Hawai'i, tomatoes are grown in commercial farms, small-scale operations, and backyard gardens. The state's tropical climate characterized by high temperatures, frequent rainfall, and elevated humidity creates ideal conditions for fungal disease development. Disease occurrence and severity are further influenced by tomato genotype and growing conditions. Identifying the prevalent pathogens and implementing targeted disease management strategies will help improve crop productivity and minimize yield losses.
Exploring fungal threats and biocontrol strategies for macadamia nuts
Macadamia nut is a signature crop and an important part of Hawaii's agricultural industry. Its production has declined over the past decades due to challenges posed by insects and diseases that damage the trees or compromise nut development and harvest quality. Ongoing and expanded research focused on improved pest monitoring and management strategies is essential to safeguard this valuable crop in Hawai'i.
Fungal ID and disease diagnostics
Proper pathogen identification and disease diagnosis are necessary for making informed field management decisions before, during, or after the growing season. Proactive detection of recurring, new, and emerging diseases enable timely interventions and mitigates the risk of widespread disease outbreaks that could significantly impact crop production and increase management costs.
