Barb Corwin, MU Extension
explains how digital imaging can make plant
diagnosis possible from many miles away.
Barb Corwin with the MU Extension Plant Diagnostic Clinic
spoke Wednesday evening in concurrent sessions about a newly
designed site in which users could upload digital images of
diseased plants from anywhere in Missouri. Corwin's talk
started out with a basic introduction to digital imaging,
containing topics such as:
The MU Extension Plant Diagnostic Clinic was created to
achieve remote diagnosis of plant diseases, said Corwin.
She went on to say that local extension offices have been
equipped with digital cameras for this purpose. Expected
- Digital Cameras vs. Flatbed Scanners,
- Image sizes,
- Image resolution,
- Cropping photos, and
- Including size references in photos
Submitted plant photos and information will be kept
confidential. All a user needs is access to a digital
camera or scanner, photo editing software, and the Internet.
- Rapid support for affected plants,
- Images can be used for direct diagnosis, and
- Users can supply supplementary information with their photos.
The MU Extension Plant Diagnostic Clinic is accessible online at http://agebb.missouri.edu/pdc/.
