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.

Soybean cyst nematode (SCN) is adapting and reproducing on SCN-resistant varieties, and the SCN Coalition has reformed to help the industry speak with one voice on SCN management. Coalition leaders – like Greg Tylka, Iowa State University nematologist and George Bird, Michigan State University nematologist – are working with partners exhibiting at Farm Progress Show 2018 in Boone, Iowa, to spread the word about SCN best management practices at the show. You can visit partners exhibiting at the show including BASF (Lot 744); Bayer at (Lot 1126); Corn+Soybean Digest in the Visitors Hospitality Tent (Lot 631); Growmark FS (Lot 660); Iowa Soybean Association (Lot 740); Monsanto (Lot 30S); Pioneer (Lot 634); Syngenta (Lot 402 and Annex 7000); and WinField United (Lot 617).  

You can also catch scheduled presentations from Coalition leaders:

  • Tuesday, August 28 at 9:30 a.m. Central in the Pioneer Tent (Lot 634)
  • Wednesday, August 29 at 4 p.m. Central in the Pioneer Tent (Lot 634)
  • Thursday, August 30 at 9:00 a.m. Central in the Pioneer Tent (Lot 634)

You’ll learn about why the SCN Coalition is back and how the SCN pest is evolving.

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. 

Iowa State University Nematologist Urges Farmers to Refocus On Soybean Cyst Nematodes. SCN Coalition announcement.

Ames, Iowa (April 16, 2018) - Farmers preparing for spring planting would do well to renew their commitment to managing soybean cyst nematodes, according to an Iowa State University plant pathologist.
“I’m doing everything I can to convince farmers that we are on a slow-moving train heading towards a cliff," Greg Tylka said of the push to revive a program called the SCN Coalition.

New SCN Coalition Urges Soybean Farmers To Research shows nematodes are becoming

Waukesha, Wis. (Feb. 28, 2018) – After a 20-year hiatus, the SCN Coalition is back encouraging soybean farmers to “Take the test. Beat the pest.” Like the predecessor, the new SCN Coalition is a public/checkoff/private partnership formed to help the agricultural industry speak with one voice about soybean cyst nematode management.

Research Led Formation Of New SCN Coalition. As SCN reproduction increases in farmers' fields, yields decrease.

Waukesha, Wis. (Feb. 28, 2018) – Analysis of soybean variety trials conducted by Iowa State University (ISU) shows conclusively that soybean cyst nematode (SCN) is adapting and reproducing on the PI 88788 resistance source – used in more than 95 percent of resistant soybean varieties – and yields are decreasing. Reversing this trend requires a comprehensive SCN management plan, a goal of the SCN Coalition.

Known SCN-Infested Counties. List continues to grow.

Soybean cyst nematodes impact almost every soybean growing area in the U.S. and are moving into Canada. In the U.S. alone,  70-80% of U.S. soybean-growing counties are impacted. An additional 34 new SCN-infested counties were identified from 2014-17. #SCNcoalition root-illustration.png
