Who we are. Why we’re back.
We’re the second SCN Coalition – a diverse group of University researchers, Extension specialists and ag company representatives who are concerned about the evolving threat from soybean cyst nematode. Just like the first SCN Coalition from 1997, we’re encouraging growers to Take the Test. Beat the Pest.
What’s different this time? Because SCN is becoming resistant to the PI 88788 source of resistance (used in more than 90% of resistant varieties), we’re encouraging growers to “Know Your Number” and actively manage SCN. Our goal is to decrease SCN populations and increase yield potential.
The events that led to the new SCN Coalition
SCN is first discovered in northeast China
SCN is first reported in the scientific literature
SCN is given the scientific name Heterodera glycines by a Japanese scientist
SCN is discovered in the upper Midwestern U.S., in southern Minnesota and northern Iowa
SCN is discovered in Ontario, Canada, Michigan, and Wisconsin
First report of SCN causing increased soybean sudden death syndrome (SDS) symptoms and yield loss
The SCN Coalition is organized and launched with funding by the soybean checkoff through the North Central Soybean Research Program (NCSRP)
The first SCN Coalition ends as funding shifts to breeding for SCN resistance
Surveys of Missouri, Illinois, Kentucky, Tennessee, Indiana, and Ontario, Canada, demonstrate that increasing numbers of SCN populations are reproducing at greater levels on PI 88788
First published report of relationship between high SCN and high soil pH in the field
SCN is discovered in Quebec, Canada
University, industry, and growers come together to discuss how to avoid another resistance crisis in agriculture similar to the herbicide resistance problem. Their decision: Build a second SCN Coalition
