The Minnesota Soybean Research & Promotion Council (MSR&PC) and University of Minnesota are hosting a regional summit on the use of resistant varieties to manage the soybean cyst nematode (SCN).

SCN is a major yield limiting factor for soybean. SCN resistant varieties are widely used for managing this pest but concerns over the long term effectiveness of these varieties are developing.

Managing soybean yield losses using SCN resistant varieties and maintaining the effectiveness of these resistance genes is the topic of a day long summit. Nematologists, pathologists and soybean breeders from upper Midwest land grant universities and private companies will share information at this regional meeting

This summit is intended for soybean researchers, agronomists, consultants, extension educators and others who have a desire to understand the “nuts and bolts” of SCN resistant varieties.

The summit will be held:
September 6, 2007
8:30 am - 5:30 pm
Best Western
North Mankato, MN
