My academic interest is in the applied plant pathology and plant disease epidemiology. Using various statistical and analytical tools, behaviors of a pathogen in the field can be characterized, and the information can be used for the development of biologically, environmentally, and economically sound disease management tools. At Virginia Tech, I engage in a range of research and extension activities, including exploration of cultural and chemical means of disease management, fungicide and fungicide-alternative testing, variety susceptibility evaluation, and development of novel diagnostic tools. His current research includes: 1) Epidemiological studies of grapevine leafroll associated virus and its vectors; 2) Development of map-based disease risk assessment tools for grape and apple diseases in Virginia; 3) Study of infection process of ripe rot of grape; 4) Trunk diseases management, 5) Development of organic wine grape disease management strategies, and 6) Fungicide efficacy evaluations.
Open House Presentation: Grape Pathology Program
- “New detection, research, and extension tools for managing wood-canker diseases of fruit and nut crops” sponsored by the USDA/NIFA Specialty Crop Research Initiative.
- “Understanding Grapevine Virus Complex, and Development of Grapevine Leafroll Disease Management” supported by Virginia Wine Board
- “Investigating the lifecycle of ripe rot of grape caused by Colletotrichum species.” Supported by Virginia Wine Board and VDACS Specialty Crop Research Initiative block grant
- “Re-visiting Pierce’s Disease in Virginia” supported by CALS internal competitive grant
- “Establishment of Virginia wine grape vineyards using organic production methods” supported by VDACS Specialty Crop Research Initiative block grant
- "Development of a web-based grape disease risk assessment system" supported by Southern Region Small Fruit Consortium, VDACS Specialty Crop Research Initiative block grant, and Virginia Agricultural Council
I have been active on extension programs target growers as well as Cooperative Extension agents with training in disease identification and management, using the web and traditional resources. The goal of my extension program is to support stakeholders to make informed wine grape disease management decisions. The objectives of my extension program are to educate stakeholders how to better manage grape diseases that could reduce grape production. My extension program and my research program are integrated and share the same goals, which is the development of environmentally, biologically, and economically sound disease management strategies.
I take an approach where my research program directly feed into my extension program. Please refer to projects under research section.
