Episode 191 – BONUS! Soybean Red Crown Rot: Emerging Threats and Management Strategies

We ran out of time last week with guest Dr. Horacio Lopez-Nicora so we doubled up our releases to cover soybean red crown rot, an emerging and increasingly concerning disease in Midwest production systems. He explains how the pathogen develops, the environmental conditions that favor infection, and why red crown rot can be difficult to distinguish from other soybean wilts and root diseases in the field. Dr. Lopez-Nicora also highlights current research and management options, including the role of resistant varieties, crop rotation, and integrated disease management practices aimed at reducing risk and limiting yield loss. Listeners will come away with practical guidance on scouting, diagnosis, and proactive strategies to stay ahead of this potentially devastating soybean disease.

Episode 190 – Soybean Foliar Diseases

In this episode, guest Dr. Horacio Lopez-Nicora joins us to unpack the evolving landscape of soybean foliar diseases and what growers need to know for effective management. Dr. Lopez-Nicora discusses the most prevalent foliar issues in soybean production, including the environmental conditions that drive disease development and the challenges of timely diagnosis in the field. He also explores integrated management strategies, emphasizing the importance of scouting, disease forecasting, and fungicide decision-making to protect yield while preserving economic return. Listeners will gain practical, research-based insights into disease identification, resistance considerations, and season-long approaches to reducing risk in soybean fields.

Episode 121 – Corn and Soybean Diseases

Mid to late summer attentions quickly turn to fungicide applications and talk of what needs sprayed for that particular year. This year is no exception with the varying weather conditions that seem to appeal to each and every disease. Dr. Horacio Lopez-Nicora and Jason Hartschuh talk about which diseases in corn and soybeans we should watch out for and provide more information on scouting and pulling the trigger on application.

Episode 115 – Insect and Disease Pressure in Cool Soils

Planting conditions were really good in early April which led to a significant amount of corn and soybeans planted early this year. With the turn to cold, wet conditions, much of that seed has sat without emerging for 2-3 weeks. What impact will that have on insect and disease pressure? How might it affect replant considerations?

To answer these questions, Dr. Kelley Tilmon and Dr. Horacio Lopez-Nicora join us to discuss the effectiveness of seed treatment, which insects and diseases we should be concerned about and some cultural considerations to prevent infestations.
