Plant diseases

Leaf spots, fruit rot, wilt and unusual plant growth or color can all be symptoms of a plant disease problem.

Identify the insect, disease or nonliving factor that is causing problems in your garden with the UMN Online Diagnostic Tool What’s wrong with my plant? or send a diseased plant sample to the UMN Plant Disease Clinic.

Find more information about common plant disease problems below.
