“Soybean Cyst Nematode (SCN) is the most important nematode in soybeans because it causes the most damage. It is the number one yield robbing soybean pathogen in North America,” said Marisol Quintanilla, Michigan State University Extension Nematologist.
It is important for a farmer to know if they have SCN in their field, and at what level.
“A key in SCN management is to try to avoid getting it in the field. The first step is to sample and determine if it is present or not. Collect soil samples and know your numbers,” Quintanilla said. “Some labs can also determine the type of SCN present.”
If SCN is not present, then the goal is to keep it out. “SCN cannot spread on its own,” said Quintanilla. “SCN needs to be spread by something that moves soil, (such as tillage or planting equipment).”
