The fungal pathogen Verticillium dahliae has resulted in significant losses in numerous crops in coastal California, but lettuce remained unaffected until the mid-1990s. Since then outbreaks have… Expand
A Real-Time, Quantitative PCR Seed Assay for Botrytis spp. that Cause Neck Rot of Onion.
A real-time fluorescent polymerase chain reaction (PCR) assay was developed using SYBR Green chemistry to quantify the Botrytis spp. associated with onion (Allium cepa) seed that are also able to… Expand
Carrot Purple Leaf: A New Spiroplasmal Disease Associated with Carrots in Washington State.
During the growing seasons of 2003 and 2004, a disease occurred in several carrot crops in south central Washington with symptoms suggestive of infection by phytopathogenic mollicutes (phytoplasmas… Expand
Evaluation of Onion Cultivars for Resistance to Enterobacter cloacae in Storage.
Sixty-nine storage onion (Allium cepa) cultivars (seven white, five red, and 57 yellow cultivars) were evaluated in the Washington State University Onion Cultivar Trials in the semiarid Columbia… Expand
Disease Severity and Yield of Sweet Corn Hybrids with Resistance to Northern Leaf Blight.
Reactions of supersweet (sh2) sweet corn to northern leaf blight (NLB) and associated yields were evaluated in Belle Glade, Florida and Urbana, Illinois in yield-loss trials, hybrid evaluations, and… Expand
Greenhouse Evaluation of Seed and Drench Treatments for Organic Management of Soilborne Pathogens of Spinach.
The efficacy of 14 seed and drench treatments for control of soilborne damping-off pathogens in organic production of spinach was evaluated in a greenhouse study. The efficacy of each treatment was… Expand
Variation Associated with Silk Channel Inoculation for Common Smut of Sweet Corn.
Efforts at breeding for resistance to common smut of maize (Zea mays), caused by Ustilago maydis, are hampered by the lack of a reliable and efficient method of inoculation. Silk channel injection is… Expand
Sequence diversity of the nucleoprotein gene of iris yellow spot virus (genus Tospovirus, family Bunyaviridae) isolates from the western region of the United States
Summary.Iris yellow spot virus (IYSV), a tentative virus species in the genus Tospovirus and family Bunyaviridae, is considered a rapidly emerging threat to onion production in the western United… Expand
