Plant and Insect Diagnostic Clinic

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.
