Tree Health, Fungi and Pathology - Exploring their World

 

 

Due to increasingly extreme climatic conditions, trees are more and more exposed to biotic and abiotic stress factors, making them susceptible to damaging agents, such as pathogenic fungi. The trees in our forests and cities are increasingly confronted with novel, spreading pathogens.

Our research addresses:

  • What factors favor the spread of new pathogens
  • What strategies exist for increasing the resilience of trees against new pathogens
  • What interactions exist between endophytes and pathogens
  • The development of diagnostic methods for the identification of pathogens, in order to act preventively
  • Methods for tracking disease outbreaks
