Foliar Fungal - Main
The research program in this lab deals with the etiology, epidemiology and control of foliar fungal diseases of citrus. Our current research focuses on the following diseases in Florida: Postbloom fruit drop (PFD), Greasy spot, Citrus scab, Alternaria brown spot, Melanose and Citrus Black Spot, caused by Guignardia citricarpa, an exotic disease of concern to Florida growers. Much of the program is devoted to the basic biology and epidemiology of those diseases and weather-based forecasting to determine the need for and timing of fungicide applications. Fungicides are routinely evaluated for disease control under field conditions. Morphology, molecular techniques, pathogenicity and host range are also used to characterize the species and pathotypes of fungal pathogens of citrus.
For general information, treatment strategies and graphic illustrations of foliar fungal diseases of citrus, refer to the 2007 Florida Citrus Pest Management Guide. The fungicide reports contained in each disease section may be of some interest to citrus growers, grove managers and agrichemical representatives. These reports include the recent performance (1998 to 2006) of various fungicidal compounds against PFD, Scab, Alternaria Brown Spot, Greasy Spot and Melanose.
Useful publications. Researchers may find Dr. Timmer's publication list to be of interest. This list contains a complete list of the articles published in refereed and non-refereed journals as well as popular articles. Requests for reprints can be made to Dr. Timmer at the address given above or via email.
Lab personnel. For those who would like to know more about the people performing the research in our lab, the personnel profiles contain biographical information and resumes of all current employees. A list of our collaborators is also included. Although we are a small and diverse group, we try to pool our talents and skills to advance scientific knowledge in plant pathology as well as enhance production capabilities of citrus growers.
