The SCN Coalition wants soybean growers to consider the impacts soybean cyst nematode (SCN) can have on their bottom lines if left unmanaged. SCN is the No. 1 yield-grabbing soybean pest in North America.
In a new video series titled, “Let’s Talk Todes,” Iowa State University Nematologist Greg Tylka explains why soybean growers need to consider the economic impacts of SCN.
SCN is considered to be the most damaging pathogen, in part, because the most common source of resistance known as PI 88788 isn’t as effective as it once was.
“Don’t be complacent. The nematode doesn’t actively spread itself; it’s spread by anything that moves soil,” he adds. “It’s spreading within states where it’s well established like Iowa and Illinois, and more recently moved into areas of the Upper Midwest like North Dakota.”
North Dakota State University Plant Pathologist Sam Markell encourages growers to test for SCN so its spread can be tracked.
“If we find it, we need to manage it, and we can learn from the situation in states like Iowa,” he said. “Growers will benefit by incorporating varieties with the Peking source of SCN resistance into their rotation. This can translate into yield benefits in areas where PI 88788 is not as effective, and rotation between these two sources of resistance can help keep the nematode from overcoming PI 88788 in new areas. Early detection, frequent monitoring and strategic management are keys to managing the No. 1 yield-grabbing pest of the soybean crop in North America.”
