Ferrarezi Citrus Hort Lab Extension: Dr. Rhuanito "Johnny" Ferrarezi
Dr. Rhuanito “Johnny” Ferrarezi leads IRREC’s citrus horticulture research and extension in the world’s premier grapefruit production region.
Dr. Ferrarezi’s extension program involves methods to support citrus producers with their efforts to protect crops from citrus greening by nutrition and irrigation management for growers to extend HLB affected grove life.
As a first step to fight citrus greening, he is working to create an integrated solution that will involve research scientists from multiple disciplines. His research is taking place in IRREC’s citrus experiment groves and greenhouses where he will demonstrate good practices with extension activities.
A prolific author, he published three catalogs for research projects; a book on nutritional guidelines for citrus seedlings production; and, wrote several book chapters about plant nutrition. He wrote and published multiple 18 peer-reviewed journal articles in publications such as the Journal of the American Society for Horticultural Science, HortScience, Journal of Plant Nutrition, HortTechnology, Frontiers in Plant Science, Tree, Weather and others.
