Department of Plant Pathology



The U-scout program is a joint collaboration between the Department of Plant Pathology and the North Florida Research and Education Center of the Institute for Food and Agricultural Sciences, University of Florida. This website has been designed as part of our research and extension program on vegetable and ornamental crops with support from numerous centers within the University of Florida including

  1. Department of Plant Pathology, Gainesville, FL - Lead institution

  2. North Florida Research and Education Center (NFREC), Quincy, FL - Lead institution

  3. Gulf Coast Research and Education Institution (GCREC), Wimauma, FL

  4. Tropical Research and Education Center (TREC), Homestead, FL

  5. Florida Plant Diagnostic Network Labs (Gainesville, Quincy, Wimauma, Immokalee, Homestead, FL)

  6. University of Florida Cooperative Extension &

  7. Florida Agricultural and Mechanical University, Tallahassee, FL (collaborating institution)

U-scout includes a plant disease DATABASE, plant disease BLOG, plant disease WATCH, plant disease management TUTOR, plant disease ALERT, plant disease MONITOR and a plant disease PUBS section.

The goal of this interactive website is to routinely inform and train extension agents, commercial scouts, master gardeners, industry personnel, vegetable and ornamental crop producers and landscapers on latest identification of plant pathogens and its management. The seed funding for the U-scout program came from a grant from the office of the Dean for Extension, Institute for Food and Agricultural Sciences, University of Florida (2011 - 2012). Current funding for this program is through a grant from the United States Department of Agriculture (2013 - 2016) in partnership with Florida A & M University.
