Plant Disease Diagnosis


The NDSU Plant Diagnostic Lab strives to provide timely and accurate plant disease diagnosis and research-based recommendations.

Our lab accepts both physical samples and digital images from homeowners and commercial clientele. We analyze plant and soil samples for pathogen/biotic and abiotic disorders. We also conduct phytosanitary testing in support of ND Department of Agriculture (Plant Industries Division).

Our services are available to anyone in the United States; however, if you reside outside of North Dakota, we suggest to contact your local Extension office or a diagnostic lab/clinic within your state/region for assistance.

Please see the sample submission form and guidelines here.
