Testing in the lab

The Plant Nematology Laboratory determines the number of nematodes or nematode eggs in soil samples submitted by

  • Farmers
  • Golf course managers
  • Agricultural consultants
  • Other labs
  • MU researchers

A fee is charged for each sample analyzed

The primary lab procedure we perform is analysis of soil samples for number of soybean cyst nematode (SCN) eggs. SCN reduces soybean yields significantly and is primarily controlled by crop management methods such as rotation of resistant soybean varieties with other non-host crops. The lab analysis helps producers decide what crops to plant. Most samples come in the fall after harvest and in the spring before planting.

We also determine the number of plant-parasitic nematodes in the samples from golf courses or from fields where cotton, corn, certain vegetable crops, and other crops susceptible to plant parasitic nematodes have been grown.

Plant-parasitic nematodes other than SCN are identified as vermiforms (or verms) or by vermiform identification plus egg count for SCN.

Laboratory procedures vary depending on the analysis to be performed.
