Study: Where bison roam could spread microbes

A new study from University of Florida and Kansas State University researchers found that bison carry plant-associated fungi in their saliva, with the potential to spread fungi across the prairie.

Probing plant infections

A UF professor deploys unusual methods in the field to investigate bacteria that infect tomato and pepper crops.

Epidemiology of citrus greening

UF/EPI mathematical disease modeler Burton Singer has coauthored a book chapter reviewing the epidemiology of citrus greening.

Eggplant’s newest pathogenic fungus

A known pathogenic fungus, so far only reported to cause disease in two crops, has ensnared a third victim: eggplants. UF plant pathologists affiliated with both UF’s Institute of Food and Agricultural Sciences and the EPI, were the first to describe Lasiodiplodia hormozganensis’s jump to a new host.

Lethal bronzing spreads to new palm hosts, counties

A new study adds four additional species to the growing list of palm trees susceptible to lethal bronzing disease, for a revised total of 16. Researchers with UF’s Emerging Pathogens Institute and the Institute for Food and Agricultural Sciences sampled hundreds of palms in Florida to identify the new hosts, all of which are common ornamentals found throughout central and southern portions of the state. They also found the disease has spread to eight new counties.

Global crop surveillance system, bulwark against disease

proposed global surveillance system would act as a bulwark against diseases that threaten food crops. UF plant pathologist Karen Garrett, who is affiliated with both IFAS and the EPI, coauthored a policy paper in Science outlining a visionary system that would link existing local and national programs to identify, predict, monitor and mitigate outbreaks of emerging crop diseases.
