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 factors that are 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.

Growing healthy vegetables provides basic garden care information that will help you prevent and control plant diseases and damage caused by insects and environmental factors in your home garden.

See the Clean and disinfect gardening tools and containers page for tips on preventing the spread of diseases through tools.
