Plant Disease Diagnosis: hands-on workshop

Twenty participants examined plant diseases and disorders on live material in the laboratory and in the landscape, and learned simple diagnostic techniques that County Agents can use in the field or at their office.  Agents toured the PDIC and “walked through” the process of diagnosing a clinic sample.
