Seed Health Testing

Seed Health Testing

The NDSU Plant Diagnostic Lab performs a limited number of seed health tests. The NDSU Plant Diagnostic Lab is USDA-accredited to perform screening of seed lots for Clavibacter michiganensis subsp. sepedonicus (causal agent of potato bacterial ring rot) for export. Other seed health or phytosanitary tests are also available at the NDSU Plant Diagnostic Lab. For additional services and fees, please click on the 'Services and Fees' link in the vertical menu, at left.

Seed Health Information Request Form - Please fill out this form and submit with sample

If you have questions regarding how to send a sample for seed health testing, please contact the NDSU Plant Diagnostic Lab (click on 'About the Lab,' in the menu at left, for contact information).

The North Dakota State Seed Department (NDSSD) performs seed quality testing (such as germ and purity) and seed health testing. NDSSD is a separate entity. For more information on NDSSD and the services it offers, click here.

Disclaimer: Seed health and phytosanitary testing by the NDSU Plant Diagnostic Lab is completely self-supportive. The Lab is intended as a service to the seed and grain industries in an effort to bring the latest testing technology to the grower.

The NDSU Plant Diagnostic Lab cannot be responsible for the accuracy or uniformity of samples. Those who submit samples should strive to provide representative samples. Since disease losses in the field are also determined by conducive environments and additional factors, a low disease rating or an organism that is not detected in a submitted sample is not a guarantee that losses will not occur.
