Waukesha, Wis. (Jan. 15, 2019) – In some soybean-growing areas, soybean cyst nematode (SCN) is overcoming the main source of genetic resistance (PI 88788) used in 95 percent of commercially available SCN-resistant soybean varieties – and negatively impacting yields. So research scientists funded by the soybean checkoff (United Soybean Board and the North Central Soybean Research Program) have been developing new sources of genetic resistance and new SCN resistance management strategies.

The SCN Coalition recommends using soil test results to develop a management strategy

Waukesha, Wis. (Dec. 11, 2018) – The SCN Coalition encourages soybean farmers who “took the test to beat the pest” this fall to develop a soybean cyst nematode (SCN) management strategy for the 2019 growing season. “Now that you’re armed with egg counts, you and your advisors can use that data to actively manage SCN,” says Carl Bradley, plant pathologist from the University of Kentucky and a leader of The SCN Coalition.

New Booklet Describes How Farmers Can Beat SCN Resistance

The SCN Coalition is offering a free 32-page booklet called Beat SCN Resistance. It tells the story of how soybean cyst nematode is adapting to the genetic resistance source used in 95 percent of commercially available resistant soybean varieties – and how that’s driving down yields. The booklet describes several SCN management tools and options, and includes recommendations for farmers in different growing regions. Stories from individual farmers who are actively managing SCN are also included.

One Step Closer to SCN Control Iowa State University researchers have discovered the mechanism that gives SCN power over plants

In a recent discovery by Iowa State University researchers, they determined one-way nematodes alter the activity of plant genes. Based on their findings, they concluded that the nematode injects a mixture of proteins into plant cells, thus altering the conformation of the host plant’s genetic material. This results in the redirection of the plant’s gene expression structure to enable parasitism.

While this discovery doesn’t eradicate SCN, the outlook is promising. Researchers will leverage this information to piece together a larger and more clear understanding of soybean cyst nematodes. They are hopeful similar findings will occur through future trials, which could result in the ability to engineer more SCN resistant seed varieties.

The SCN Coalition encourages piggybacking on fall fertility sampling

Waukesha, Wis. (Oct. 9, 2018) – For soybean farmers and agronomists doing soil fertility sampling and testing this fall, “it’s also a great time to pull soil samples for soybean cyst nematode (SCN) testing while you’re in the field,” says Sam Markell, North Dakota State University plant pathologist and leader of The SCN Coalition. It’s the first step in actively managing SCN resistance, which is a growing problem for many soybean farmers, whether they realize it or not.

SCN Expanding To New Areas Coalition Urges Growers To Take The Test. Beat the Pest.

We’ve expanded soybean acres dramatically in the last 20 years, and when you do that, you expand the problems, too,” advised Sam Markell, North Dakota State University plant pathologist. AgriTalk host Chip Flory talked to Markell and Kaitlyn Bissonnette, University of Missouri plant pathologist, about identifying and managing soybean cyst nematode (SCN) in different soybean growing areas and the return of the coalition after its 20-year hiatus. The SCN Coalition leaders were interviewed as part of AgriTalk coverage at the Farm Progress Show.

Learn How SCN Is Overcoming Resistance New animation demonstrates how soybean's best defense is faltering

Soybean plants growing in fields across the United States and Canada are fighting a pest we thought was under control. After 20-plus years of relying on the same source of SCN resistance – PI 88788 – SCN is becoming aggressive, feeding and reducing bean yields as they overcome SCN resistance. Unfortunately, the PI 887888 source of resistance is used in 95% of all commercial soybean varieties. Watch a new video animation, produced by the SCN Coalition and learn more about this and what farmers can do to fight it.

The New SCN Coalition At Commodity Classic. Why it's more important than ever to take the test. Beat the pest.

Field tests prove that yield-robbing soybean cyst nematode (SCN) populations are rising and spreading, despite use of SCN – resistant soybean varieties. Listen to how successful growers — Ron Heck, Perry, Iowa, and Pat Duncanson, Mapleton, Minnesota — are activelly managing SCN in their fields. Dr. Greg Tylka, a leading nematologist from Iowa State University, moderates the discussion and advises growers to think of SCN like high blood pressure: no one magic bullet can manage high blood pressure or SCN. Taped at 2018 Commodity Classic, February 27-March 1, 2018, in Anaheim, California.
