Fungal and oomycete test kits: target scope and specimen limits
Distinguish a named species from a genus-level product before ordering. This group includes Phytophthora sojae, Leptosphaeria maculans, Colletotrichum spp., Pythium spp. and Fusarium spp.; the catalog names are not interchangeable.
What to check first
A search for a soil pathogen kit does not establish that soil is covered. The current Colletotrichum, Pythium and Fusarium genus IFUs list corn stalks and seeds; Phytophthora sojae lists leaves and stems. Request confirmation before changing the matrix.

Selection questions to resolve
Can I use soil in this Phytophthora sojae kit?
The IFU lists leaves and stems, not soil. Discuss soil or other unlisted matrices with the product team before changing the procedure.
Does Fusarium spp. identify Fusarium graminearum specifically?
This product is labeled at genus level and its IFU lists corn stalks and seeds. Do not report a species identity from that label. The Fusarium graminearum wheat product is listed separately.
Is this a general soil test for Pythium?
The current IFU specifies corn stalks and corn seeds. Soil is not listed, so this page does not claim a validated soil-testing workflow.
Does a Colletotrichum genus name mean every crop sample is covered?
No. The current IFU lists corn stalks and corn seeds. The genus label does not establish suitability for every crop or specimen, or identify an individual species within the genus.
Is the blackleg / Phoma stem canker kit a general fungal assay?
No. This product names Leptosphaeria maculans. The common disease names help locate the product, but they do not expand it to other fungi or unlisted specimen types.
Before you order
- Check the full target name, abbreviation and SKU; do not order solely from a common name or symptom description.
- Confirm that the actual specimen is within the IFU scope. Ask about unlisted matrices, preservation methods or specimen conditions.
- Read the matching IFU for preparation, controls, storage and result interpretation.
- Confirm equipment and program compatibility. Kits and the platform are separate products; do not assume any PCR instrument or third-party reader is compatible.
- For a quote, provide testing volume, existing equipment and destination, and confirm the sales pack, shipping and delivery arrangements.
