Elizabeth Fichtner recently joined UC Cooperative Extension as a Fruit and Nut Advisor in Tulare Co. Elizabeth is originally from New York and completed her BS in Plant Science at Cornell University in 1997. Elizabeth co-majored in both Plant Pathology and Soil Science for both her MS and PhD at NC State University in Raleigh, NC. After completing her PhD she joined UC Davis as a post-doctoral scientist and developed a research program on emerging forest diseases including Sudden Oak Death. Elizabeth’s research focused extensively on survival and transmission of pathogens in forests, both in the United Kingdom and California. Elizabeth enthusiastically welcomes the opportunity to continue applying her background to orchard systems and looks forward to working with Tulare County growers to learn the culture of the crop and address new challenges.

Crown gall on walnuts: assessing origin of infection, disease management and prevention
Crown gall is one of the most common diseases observed in commercial walnut orchards in California. The disease, caused by a plant pathogenic bacterium, is easy to identify based on symptomology alone. Agrobacterium tumefaciens causes crown...
The dynamic state of spurs in almond
Over 80% of the almond crop is borne on short, compact vegetative shoots called spurs. Each season, however, only a portion of the spur population on a given tree supports fruit production. Because of their role in supporting productivity and yield,...
Distribution of chlorosis in almond orchards may help assess potential irrigation-related issue
The first step in assessing the cause of canopy chlorosis and decline in an orchard is mapping the distribution of the symptoms. If a pattern of chlorosis is similar across irrigation lines, then the cause of the problem may be related to over- or...
