Grants:"Impacts of elevated CO2 on plant disease severity at the Duke FACE site", Not currently funded,
Description:Despite the influence of environmental factors on plant disease, research addressing the impacts of climate change on plant pathosystems has been limited. Plant disease consists of the interaction between host plant, pathogen, and environment and changes in any of these components can significantly impact disease incidence and severity. The Duke FACE site provides a unique opportunity to assess how interactions between plants and pathogens will change under elevated CO2 conditions. In the summer 2002, we will initiate surveys of several deciduous understory plant species and the dominant loblolly pines in the site to identify important pathosystems. After initial pathogen assessments, surveys will be conducted in ambient and elevated CO2 rings to assess the incidence and severity of foliar and stem diseases on randomly selected individuals of designated plant species.
Update 11/3/2006:We have been assessing natural levels of plant disease incidence using leaf images from the Duke FACE site. I would like to correlate our disease data with weather data from the site for 2000-2005. All disease assessment is already complete.
