The buildup of soybean cyst nematode (SCN) on SCN-resistant soybean varieties is a growing concern across the Midwest.
“I liken it to the cliché ‘a train wreck in slow motion’,” says nematologist Dr. Greg Tylka, director of the Iowa Soybean Research Center.
Tylka says the most common source of SCN-resistance, PI 88788, is losing its effectiveness due to overuse.
“We’re already continuing down a path that eventually could mean that common PI 88788 resistance might not be resistant at all,” Tylka says.
