Aerial dissemination of plant pathogens: tools, analysis and impact on understandings epidemics

Airborne spread of Pseudomonas syringae and Botrytis cinerea

Forecasting the aerial dissemination of a plant pathogen at different spatial scales can lead to refined prediction of outbreaks of epidemics in specific areas. However, it is virtually impossible to observe directly the long distance movements of airborne microorganisms. To tackle this issue, we chose the approach of coupling Lagrangian models of air mass trajectories with the genetic characterization of strains collected from dry air and precipitation.

Our research are focused on Botrytis cinerea  and  Pseudomonas syringae. Ongoing studies are in progress to understand the origin of the airborne inoculum of Sclerotinia sclerotiorum.
