Seed-borne diseases and poor seed quality can lead to poor produce quality, as well as significant crop losses with affect overall yields. Planting healthy, disease-free seed is a first line of defense against infectious pathogens and environmental stressors.
This is why Sunburst provides testing services to evaluate seed health and quality: To provide the grower with the diagnostic information they need to ensure the maximum possible crop performance and yield.

Seed Quality Testing
We provide seed health testing services for a variety of vegetable and field crops, using a number of tests to evaluate for quality attributes such as germination percentage.
By being proactive in evaluating the quality of your seed before planting, you give yourself the best possible chance for growing crops with record yields.
Seed Disease Testing
We use a variety of sophisticated diagnostic techniques, including pathogen selective media plates, microscopy, ELISA, real-time PCR, and gene sequencing to identify bacterial, viral, and fungal pathogens that can infect seeds and have a deleterious impact on plants grown from infected seeds.
The Sunburst Plant Disease Clinic is accredited by the National Seed Health System (NSHS).

Xanthomonas campestris pv. campestris – Plating/PCR
Phoma lingam – Grow Out
Xanthomonas campestris pv. carotae – Planting/PCR/Pathogenicity
Alternaria radicina – Grow Out
Acidovorax avenae ssp. citrulli – Planting/Grow out/PCR/ELISA
Cucumber Green Mottle Mosaic Virus (CGMMV) – ELISA
Melon Necrotic Spot Virus (MNSV) – ELISA
Squash Mosaic Virus (SMV) – ELISA/Pathogenicity
Lettuce Mosaic Virus (LMV) – Pathogenicity/ELISA
Peronospora farinosa f.sp. spinaciae – Wash Test

If you have any questions about the seed diseases we test for, or the seed quality tests we offer, please contact us for more information.
Some plant diseases, such as certain forms of corn ear rot, are caused by fungi that can produce mycotoxins in certain conditions. Mycotoxins can cause serious health effects and even death in people and animals that consume infected crops.
We offer mycotoxin testing services for food and feed, including corn, corn flour, corn gluten meal, corn germ, corn germ meal, wheat, wheat bran, wheat middlings, wheat gluten, whole wheat flour, white wheat flour, sorghum, oats, barley, soybean meal, distiller’s dried grains with solubles (DDGS), milled rice, rough rice, whole rye, and more.
Early detection of mycotoxin is an important means of managing and mitigating infections before they result in complete crop loss.
To help enable the earliest possible detection of mycotoxin contamination in food and animal feed, Sunburst offers the most sensitive protein-based methods of detection currently available on the market.

“I have used Sunburst Plant Disease Clinic for close to 20 years now and I’ve been very satisfied with the level of their performance year in & year out. I have trusted their lab testing expertise in many of my soil samples for disease diagnostics and the results I receive from these soil tests are vital to many of my decisions out in the field. I have learned to trust quite a lot of the results that their lab produces. Their office staff also communicates very well & are very responsive to our questions or needs. I have always received excellent service from Sunburst in all departments & look forward to continued business with them in the future.”
