Impact of foliar insecticides on soybean aphid, 2024
Soybean aphid (SBA) is a significant threat to soybean production in Minnesota, United States. To advance implementation of integrated pest management of SBA, an experiment was conducted to evaluate insecticides for efficacy against SBA. This experiment was performed at the University of Minnesota Rosemount Research and Outreach Center near Rosemount, Minnesota.

Agronomic and economic trade-offs of integrating camelina into the corn–soybean rotation
Farmers in the Upper US Midwest typically grow corn and soybeans, leaving land fallow over winter. This study explored whether adding winter camelina, a cold-hardy oilseed, between corn and soybean crops could make better use of that time. We tested early-, mid-, and full-season corn hybrids and compared plots where corn residue (stover) was removed or left on the field. Camelina yields were highest when planted early after short-season corn and where stover was removed, but these conditions reduced soybean performance. Mid-season corn hybrids struck the best balance, supporting agronomic and economic returns across the system. The key finding is that no crop can be prioritized if camelina is added. Success comes from managing trade-offs to maximize the performance of the full rotation over time. While challenging, integrating camelina could help diversify cropping systems and improve resource use in regions with long fallow seasons.
