Most Sites Showed No Yield Difference between Treated and Untreated Soybean
2011 Field Research Shows Little Yield Effect from Soybean Seed Treatments - UNL CropWatch, 2011
January 12, 2012
A seed treatment trial was conducted at four locations in Nebraska in 2011 to determine its effect on stand, disease control, and yield. The sites, part of the Soybean Management Field Days, were near Bancroft (northeast Nebraska), Clay Center (south central), Cortland (southeast), and Elba (central).

Is Treatment of Soybean Aphids Warranted at R5 or early R6?
August 25, 2011
Soybean aphids are still present, but we are nearing the period when populations decline and soybeans are less likely to incur economic yield loss. Declining night temperatures and shorter days initiate migration of soybean aphids back to buckthorn, their overwintering host.
