Soil Testing and Plant Diagnostic Services
Plant Nematology Laboratory
This laboratory tests soil and plant samples qualitatively and quantitatively
for the presence of plant parasitic nematodes. Recommendations are provided for
management strategies to reduce the effect of nematodes on plant growth and yield.
- Soybean cyst nematode (SCN) egg count
$20 per sample
- Plant parasitic nematode identification
$30 per sample
- Soybean cyst nematode modified HG type (race) test:
$75 per test, in-state
$125 per test, out-of-state
- Soybean cyst nematode full HG type (race) test:

Note for HG type testing
For Missouri soybean producers, we recommend a modified HG type test, which includes five indicator lines representing the predominant sources of SCN resistance available in Missouri. A full HG test uses all seven indicator lines of resistance and is available upon request.
Does your garden have root-knot nematode?
Root-knot nematodes are microscopic worms that can infect vegetable roots causing serious symptoms and producing galls or "knots" on the roots. The nematodes impede the flow of water and nutrients to the plant.
Magnified 100 times and stained to be visible, juvenile soybean cyst nematodes infect a soybean root. The juveniles will form feeding sites and rob nutrients from the plant.
Unexplained soybean yield losses?
SCN could be the culprit
Soybean producers who experienced unexplained yield losses this season should test their fields for soybean cyst nematode this fall, a University of Missouri researcher said.
