Research Interests :
- Etiology of New Tropical Disease:The continuous importation of new plants into the state has been accompanied by the introduction of new pathogens.Although we address all plants, we are generally focused on orchids, ornamentals, landscape, fruit, and vegetable crops.International movement of ornamentals is recognized at a pathway for global pathogen movement.New pathogens are pure cultured, hosts are challenged and causal agents are confirmed.We also conduct routine diagnostic disease analysis for nurserymen and farmers.
- Pathogen Population Biodiversity:Pathogenicity, statewide distribution, genetic, morphological characteristics and molecular analysis of pathogen populations to determine phylogenetic and pathogenic relationships among isolates in selected fungal pathogen species. We are currently working on Puccinia psidii the new rust of ohia and other Mytaceae and Fusarium oxysporum on Acacia koa. The rust research spans the globe with cooperators in Brazil, the Caribbean, and Australia.
- Determination of fungicide efficacy:Disease control efforts require the screening of fungicides to identify fungicides that will control diseases.New fungicides and low risk environmentally friendly compounds are being tested.Currently field testing fungicides for orchid diseases, P. psidii, and Coleosporium on plumeria.Lab tests on P. psidii.
