Researchers engineer durable soybean cyst nematode control

By Doug Rich

Soybean cyst nematodes (SCNs) were first discovered in North Carolina in 1954. Today these nematodes can be found anywhere soybeans are grown and have been known to cause yield losses up to 40 percent in some fields. These destructive parasites cost soybean growers in this country up to $860 million every year.

A group of researchers from the Department of Plant Pathology at Kansas State University have discovered a unique new way to control SCNs.

Harold Trick, professor; Tim Todd a nematologist; and Jiarui Li, a research assistant professor, have genetically engineered soybean plants with specific traits. When nematodes feed on these plants they ingest these traits, which turn off specific nematode genes dealing with reproductive development and overall fitness.

"What we do is target genes that we think might be vital for the nematode to survive," Trick said. "If we are able to turn these nematode genes off, we essentially can kill the nematode and provide the soybean with protection."
