Please, do not include payment with your sample submission. The total cost of testing can range from $20.00 to $100.00 for commercial production and from $20.00 to $50.00 for non-commercial production. An invoice will be generated when sample analyses are completed.


1. Plant Health Analysis

Basic Sample Submission

In-state sample submission – $20.00
Out-of-state sample submission – $40.00

  • Samples submitted for Plant Health Analysis are charged a basic submission fee according to the place of origin. This fee includes visual and microscopic inspection of the plant sample for infectious/non-infectious diseases, assessment of insect-feeding injury and insect identification, culturing for bacteria, fungi, and oomycetes, and measurement of soil pH and soluble salts.
  • Additional testing services will be charged as described below. 

Add-on Testing Services

In-house serological test – $10.00 

  • Additional serological tests (ELISA and/or Immunostrips) are available at $5.00 each.
  • The lab has limited availability of serological test kits for viruses and bacterial pathogens. This allows for rapid and sensitive testing for specific pathogens. Contact us to learn more about the available tests.

Bacterial identification (BIOLOG®) – $15.00

  • Upon request and based on culture results, a BIOLOG® metabolic analysis can be conducted.

Molecular pathogen identification – $45.00

  • Upon request and depending on the available barcodes, identification to genus or species (when possible) level can be conducted. 

Molecular pathogen detection (PCR/qPCR) – $25.00 (unless noted)

  • Upon request and/or based on culture results, detection of specific bacteria, fungi, and oomycetes can be conducted.
  • List of available molecular tests:
    • Bacterial leaf spot (Xanthomonas genus)
    • Grapevine viruses (panel of 10 viruses) – $100.00
    • Oak wilt (Bretziella fagacearum)
    • Phytophthora diseases
    • Phytoplasma diseases
    • Ramorum blight (Phytophthora ramorum) – $150.00
    • Soft rot bacteria (Pectobacterium and Dickeya) – $40.00
    • Soybean brown stem rot (Phialophora gregata)
    • Soybean sudden death syndrome (Fusarium virgulifome)
    • Verticillium wilt (Verticillium dahliae)

An additional molecular test run on the sample sample is charged at $10.00 each.

2. Plant / Weed Identification

Out-of-state samples are charged double.

Plant ID – $10.00

  • Plants may be mailed in or dropped off for identification.

Digital plant ID

Please note that specific identification is not always possible from digital images. 

We reserve the right to limit identifications via digital images based on current sample volume.

  • Digital ID of 1-3 different plants – No charge
  • Digital ID of additional plant – $10.00 each

3. Herbicide Resistance in Weeds

Out-of-state samples are charged double.

Herbicide resistance screening – $90.00

  • Learn about herbicide resistance in weeds and how to submit samples.
  • Testing includes multiple sites of action, based on seed quantity and quality.
  • MI soybean growers qualify for free testing of the following species courtesy of the Michigan Soybean Promotion Committee:
    • Palmer amaranth
    • Waterhemp
    • Horseweed/marestail
    • Common lambsquarters
    • Common ragweed
    • Giant ragweed

We reserve the right to limit herbicide-resistance samples based on current sample volume and space limitations.

4. Nematode Analysis

Out-of-state samples are charged double.

Basic nematode analysis – $25.00

  • Includes the identification of all plant-parasitic nematodes found in the soil and roots.  This is the standard nematode analysis most clients request.

Foliar nematode analysis – $25.00

  • Reports any nematodes detected in leaf tissue submitted to the lab.

Total nematode community analysis – $50.00

  • In addition to the counting and identification of plant-parasitic nematodes (basic nematode analysis), beneficial nematodes, mycorrhizal fungi, and microscopic earthworms are also counted. The nematodes are separated out into functional or trophic groups such as bacterial-feeding, fungal-feeding, and predatory.

Full SCN type testing – $75.00

  • Screens against 7 sources of soybean cyst nematode (SCN) resistance.

Mini SCN type testing – $40.00

  • Screens against 3 sources of soybean cyst nematode (SCN) resistance.

5. Verticillium Soil Analysis

Out-of-state samples are charged double. 

Wet sieving – $25.00

  • Ten grams of air-dried soil are plated for counting colonies of V. dahliae.

Dilution plating – $20.00

  • Five-gram subsamples of air-dried soil are plated for counting colonies of V. dahliae.

Both methods – $40.00

  • Both wet-sieving and dilution-plating soil assays are performed.

6. Insect, Spider, Tick, or Other Arthropod Identification

Common insect ID – No charge

  • Arthropod specimens may be mailed in or dropped off for identification. 
  • Photos of arthropods may also be sent via email free of charge. We reserve the right to limit identifications via digital images based on current sample volume.

Key-out insect ID – $20.00

  • There is usually no charge for insect identifications.  If the specimen requires extra time and effort (Key-out ID) then the lab will contact you before proceeding.
  • Out-of-state samples are charged double.
