Plant and Insect Identification

Description

The NDSU Plant Diagnostic Lab provide plant and insect identification to the public. Our lab accepts both physical samples and digital images of plants/weeds and insects. We are most likely to be successful in identifying plant and insect samples collected from North Dakota and the Red River Valley region.

For ND residents, NDSU Extension has an office in every county staffed with extension agents ready to assist in identifying plant or pest issues. Should the agents encounter challenges in diagnosing the problem or if testing services are required, they promptly forward the sample to PDL for further analysis.
