CURRENT PROJECTS
Screening of Acacia koa 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 Senior Forester Nicklos Dudley and his team at the Hawaii Agriculture Research Center (HARC).
Survey and management of prevalent tomato pathogens
Tomato (Solanum lycopersicum L.) is a widely cultivated and consumed vegetable crop worldwide. In Hawaii, 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.
Fungal identification and disease diagnosis
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.
Exploring fungal threats and biocontrol strategies in macadamia production
Macadamia nut is a signature crop and an important component of Hawaii's agricultural industry. Its production has been affected by insect pests and diseases that damage trees or compromise nut development. Ongoing and expanded research on improved pest monitoring and management strategies is essential to sustain high nut yield and quality.
Investigation and management of turmeric diseases
Turmeric (Curcuma longa) is a culturally significant and economically valuable specialty crop in Hawaii. It is cultivated for its culinary, medicinal, and wellness-related uses. The emergence of new diseases threatens rhizome quality and marketability, highlighting the need for pathogen investigation and evaluation of management strategies.
