Abstract:  Digital camera and Internet communication advances provide efficient, effective diagnostics of plant pests or disorders and identification supporting agents and clientele.  Following early transmissions of digital photos attached to e-mail, a working group of agents and specialists developed a systematic routine for submitting entomology, plant pathology, plant/weed and crop physiology/nutrition images to diagnostic labs.  A web-based Java applet provides data entry of the “virtual sample.”  Agent originated compressed images and descriptive data are routed to specialists who make determinations.  Diagnostic results are returned. Two-way traffic of information is captured in a searchable object database, building an extensive archive of images to enhance future diagnoses while bolstering user competency and supporting other educational functions.  The Digital Diagnostics and Identification System (DDIS) shortens turn-around time for traditional “biotic,” samples.  Agents, supported by specialists and programmers of Information Technology, designed the applet, wrote user guides and helps, reviewed photo techniques, compression standards, digital camera features and trained users. Where biological samples are submitted, sample, field distribution and environmental context images provide valuable diagnostic aids. Currently a pilot project is underway with 24 counties.  These counties have been equipped with cameras, adapters, and stereoscopes.  In addition 5 of these counties have been equipped with microscopes.
