​Seismic Shifts in Disease Risk

The theme for Plant Health 2021Online will be "Seismic Shifts in Disease Risk." This is a timely topic!​ As we've seen in this past year, shifts in hosts, pathogens, and environmental conditions can transform a previously minor disease to a raging epidemic. ​

In human pathology, the coronavirus pandemic shows what chaos can happen when the host-pathogen-environment axis tilts in favor of the pathogen. In plant pathology, disease risk can change incrementally or explosively. 

This theme explores major shifts in several bacterial, viral, nematode ​and fungal pathosystems from multiple perspectives, seeking common threads to help pathologists anticipate and deflect future shifts in disease risk.

We look forward to having you join us online next year as we explore this important global theme across our wider community.​​​​​
