My research and extension interests are focused on biological, cultural and chemical control of plant pathogens, disease management, biology, etiology and epidemiology of fungal plant pathogens, bacteria and viruses. I am also interested in the development of diagnostic tools and conducting phylogenetic analyses to determine geographic origin of new pathogens.
Current research projects are:
Development of management strategies for Iris yellow spot virus(IYSV) in onion using cultural methods; determination of feeding habits of onion thrips to identify local sources of IYSV.
This spring, we'll be conducting a survey to determine the distribution of streptomycin resistant Erwinia amylovora strains, causal agent of fire blight, in Utah orchards.
Identification of root-knot nematode species (Meloidogyne sp.) in golf course greens and development of species specific identification tools.
