Approximately 50 fact sheets that were originally developed by diagnosticians and Plant Pathology Faculty for use in the Plant Disease Diagnostic Clinic at Cornell University will be updated and enhanced. The fact sheets have served as a useful means of conveying information about various diseases and their pathogens to a diverse clientele. Revisions will include photographs of diagnostic features that may aid in the determination of disease. Graphically representing symptoms on the fact sheets will increase their value considerably. The completed project will allow anyone with a computer and modem to access information about specific diseases, their characteristics, and control measures.
