High SCN Numbers in 2014 - 2/10/2014

It is hard to think about planting crops with the brutally cold weather we have been experiencing in Iowa the past several weeks. But warm weather and planting season will be here in a matter of weeks. As plans are being made for the 2014 crops, farmers and agronomists should be aware that fields planted to soybeans this year may have unusually high soybean cyst nematode (SCN) numbers if soybeans were grown in the fields in 2012. The number of SCN eggs in the soil at the time of planting is a major factor determining how much damage and yield loss SCN will cause.

Trial Results Show Dual Benefits of SCN Resistance - 1/17/2014

The soybean cyst nematode (SCN) continues to be a major yield-reducing pathogen of soybeans in Iowa, and it occurs in up to 75 percent of fields in the state. Growing SCN-resistant soybeans is an important part of managing SCN. Results from Iowa State University’s nine SCN-resistant variety trial experiments in 2013 illustrate how resistant varieties can produce high yields and suppress the buildup of the nematode in infested fields.
