Dieback in invasive and agricultural plants is a common phenomenon attributed to a range of abiotic and biotic factors. In this project we are investigating the link between the introduction and establishment of a non-native plant to a new range and the subsequent dying-back of the invasive population. We are focusing on possible pathogen-related causes for dieback, especially considering the following three scenarios:1. re-association with pathogens from the non-native's native range,2. new association with pathogens in the introduced range, and3. association with cosmopolitan pathogens.
