Save on time, money, and pesticides by following economic thresholds and taking advantage of biological controls is the idea behind applied research conducted through a North Central Soybean and Research Program (NCSRP) grant led by Kelley Tilmon, Associate Professor and Soybean Extension Entomologist at South Dakota State University.
The key findings and recommendations from this NCSRP project are now available through three easy-to-follow, open-access webcasts produced by the Plant Management Network (PMN), a nonprofit publisher of crop management information:
Host Plant Resistance for Soybean Aphid
by Dr. Erin Hodgeson, Associate Professor and Extension Entomologist at Iowa State University.
Soybean Aphid Management Using Neonicotinoid-Treated Seed
by Dr. Christian Krupke, Associate Professor and Extension Field Crops Entomologist at Purdue University.

Update on Soybean Aphid Biological Control by Dr. Thelma Heidel-Baker, Postdoctoral Research Associate and Extension Coordinator at Iowa State University.

Soybean specialists urge farmers to be on the lookout for white mold, and be prepared to combat the disease. Development is bolstered by wet, cool, cloudy and humid weather at flowering.  With most soybeans just starting to or about to reach the R1 (flowering) stage, experts suggest farmers spray fungicides now in fields with a history of white mold.  Read the full article
Managing White Mold in Soybeans in the Great Lakes Region
Wed, July 2, 2014
Farmers in the Great Lakes region may be concerned about white mold in soybeans in 2014 and how to properly manage this disease.

By Martin Chilvers, Michigan State University Extension, Department of Plant, Soil and Microbial Sciences; Kiersten Wise, Purdue University; Damon Smith, University of Wisconsin; Carl Bradley, University of Illinois; and Daren Mueller, Iowa State University

White mold, also called Sclerotinia stem rot, is a disease caused by the fungus Sclerotinia sclerotiorum. It is not common every year in in the Great Lakes region, but farmers that have battled the disease in the past will want to assess the risk of white mold development as soybeans approach flowering, or growth stage R1 – plants have at least one open flower at any node.
