A Chinese warrior once said that you must first know thy enemy before you do battle.

The same can be said about citrus diseases.

Online tool helps ID citrus diseases

To help with "enemy" identification, the University of Florida. in conjunction with the U.S. Department of Agriculture's Plant Protection and Quarantine, has developed an online tool featuring 24 of the most common and commonly confused diseases and disorders.

The website houses more than 300 color images as well as keys and descriptions of each disease or disorder.

The site also can be accessed using iPhones and iPads.

The online tool is the second in a trilogy, according to a National Pest Detection Network newsletter.

The first, released in August and updated last month, was Citrus ID.

The final tool, Citrus Pests, is expected to be released early next year.

The tool can be accessed at www.idtools.org/id/citrus/diseases.

The developers also have asked that users send comments or concerns to Christina Southwick so they can improve its funtionality and usefulness.
