Plant Diagnostics Lab

The function of the plant diagnostic lab is to identify disease causing pathogens of plants and recommend appropriate treatments for their control. In the human medical field, this is the same function that a diagnostic lab would perform for a medical doctor. The ultimate goal of the diagnostic lab is to reduce the misuse and the overuse of pesticides in our landscape settings. Accurate disease diagnosis is the first step in reaching this goal. Diagnostic techniques include visual as well as microscopic examination, culture isolation, serology, bioassays, and other biotic tests. Soil testing includes pH levels and total soluble salts. Complete soil testing will be referred to the Auburn University Soil Testing Lab.
