Plant and Insect Diagnostic Clinic

MARCH 1 - MARCH 31:  Diagnosticians may not be in the lab daily, so if sending or dropping off plant material that might deteriorate, please contact us ahead of time. We want to ensure we process your sample promptly. If dropping off samples please note that ISU Campus requires face coverings. Thank you!

The Plant and Insect Diagnostic Clinic provides diagnosis of plant problems (plant diseases, insect damage, and assessment of herbicide damage) and the identification of insects and weeds from the field, garden, and home. The PIDC is a joint effort between Iowa State University Extension Plant Pathology, Entomology, Horticulture, and Agronomy.
