Welcome To Plant Pathology

Unraveling plant-microbe interactions, inspiring students, and supporting agricultural industries in Florida and around the globe …

The Plant Pathology Department at the University of Florida is an exciting place to study all aspects of plant disease and plant-microbe interactions! The richness of Florida agriculture and the many emerging pathogens provides unparalleled opportunities to work at the cutting edge of this field. We conduct research on a broad range of subjects including plant defense responses, plant genetic engineering, disease management, and microbial evolution, ecology, epidemiology, systematics, and functional genomics. Many of us participate in the Plant Molecular and Cellular Biology graduate program, the Emerging Pathogens Institute, and the Doctor of Plant Medicine Program.

      UF/IFAS study: Strawberry monitoring system could add $1.7 million over 10 years to some farms

      A University of Florida-developed web tool can bring growers $1.7 million more in net profits over 10 years than a calendar-based fungicide system because it guides growers to spray their crop at optimal times, a new UF study shows.

      UF/IFAS finding could help stop potato, tomato disease

      The potato late blight pathogen was introduced to Europe in the 1840s and caused the devastating loss of a staple crop, resulting in the Irish potato famine and subsequent diaspora. Research on this disease has engendered much debate, which in recent years has focused on whether the geographic origin of the pathogen is South America or central Mexico. Read More.

      Fungus Threatens Banana Supply

      The fruit is under assault again from a disease that threatens the popular variety that Americans slice into their cereal or slather with chocolate and whipped cream in their banana splits. But aside from its culinary delight, the banana is the eighth most important food crop in the world, and the fourth most important one for developing nations, where millions of people rely on the $8.9 billion industry for their livelihood.
