The purpose of my program is improving knowledge and understanding of plant pathogen biology, ecology, and population dynamics that could facilitate development of new disease management options and strategies on apple and pear. The goal is to elucidate quantitative parameters of pathogen survival and stress, improve understanding of plant defense responses under field conditions, and develop new or improve existing strategies for disease management. An integral part of my program are plant pathogen identification, detection, and fungicide and bactericide efficacy trials on apples and stone fruit with generating information that directly benefits the tree fruit industry of Virginia and the U.S. The two key areas of my research focus are:
(1) Plant Pathogen Biology, Ecology, and Population Dynamics with focus on:
- Survival, physiology, and population dynamics of fire blight bacterium Erwinia amylovora under stress conditions and during overwintering
- Plant defense responses (SAR, ROS, gene expression)
- Plant pathogen identification, detection, characterization and population structure (Colletotrichum spp., Diplocarpon coronariae)
- Plant pathogen resistance to biocides.
(2) Plant Pathogen Management with focus on:
- Fungicide and bactericide efficacy trials in the field and in vitro (EC50, MIC)
- Evaluation of classic and novel management options for apple and stone fruit tree pathogens
- Development of new strategies, tools, and programs for plant disease management.
My ongoing projects focus on investigating survival and population dynamics of fire blight pathogen Erwinia amylovora, population structure and fungicide resistance of fungal apple pathogens, plant defense responses (gene expression and compound accumulation), and evaluation and development of apple disease management options and programs. One of the most interesting areas in research on fire blight is the effect of different stressors such as resistant cultivar/species, drought, low temperatures, and bactericides on E. amylovora physiology, population dynamics, and pathogenicity and virulence. Very little is known about E. amylovora biology, ecology, and epidemiology during late summer, fall, and during the winter. Specifically, it is not understood which factors at these periods could influence fluctuations in population of this bacterium in the plant and how much. In order to improve and precisely apply existing fire blight control options, and provide basis for developing new tools in integrated management of this disease, more knowledge is needed about periods when E. amylovora is most vulnerable and least abundant in the host, including factors that lead towards these conditions. Knowing the key stress factors that affect E. amylovora will provide better understanding of how successful pathogen is in overwintering and what is the impact of the abundance of overwintered bacterial populations on the disease occurrence in the following season. This knowledge will enable improvement of existing and new fire blight prediction models, development of new management strategies, and allow more accurate and precise application of various practices thus securing high efficiency in fire blight control. Some ongoing projects focus on improving efficacy of post-infection spray programs for tissue invasion prevention and reduction of populations of fire blight bacterium E. amylovora. Of particular interest are sprays of different rates of copper and plant growth regulators, as well as use of penetrants to boost their efficacy. In addition, we are investigating detection and quantification of E. amylovora in tolerant and susceptible apple rootstocks.
The purpose of my extension program is to provide industry with disease management recommendations specific for each growing season. In recent years, fruit tree growers are challenged with complications associated with climate change such as mild winters, early spring frosts, unusually warm weather during bloom, and hailstorms early in the season. Some of these conditions often favor development of some of the major apple diseases such as scab, fire blight and bitter rot. Hence, the use of disease prediction models (NEWA, RIMpro) is crucial for forging out and issuing sound spray recommendations and their timing. In support of accuracy in model predictions, my lab is monitoring the start of discharge of apple scab fungus ascospores and their quantity. The need for precise timing of sprays and correct fungicide/bactericide choice for maximum efficacy has never been greater. This is primarily due to high potential for extensive damage diseases can cause, facilitated by growing apples in high density orchards, using spindle training systems, and planting new and susceptible apple cultivars and rootstocks that nurseries and fresh market prefer. My disease management recommendations are delivered at spring extension meetings, during on farm visits and tours, via phone calls and e-mails, and through workshops, fruit schools and my blog webpage: https://treefruitpathology.spes.vt.edu/posts/ My extension engagement also includes diagnosis of tree fruit problems in cooperation with AREC entomology and horticulture faculty and Virginia Cooperative Extension specialists, educators, and staff. Through networking with other research and extension plant pathologists and horticulturalists at conferences I attend, my lab delivers region wide information on tree fruit issues to the growers. Finally, through establishing and expanding my research program, my goal is to generate new information on pathogen biology, ecology and plant disease management to include into extension.
