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

by at

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

by at

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 188 – One Thing After Another

by at

Our last weather update at the beginning of March had us talking about lingering drought across the state. Well we can say that has been taken care of and then some. This spring has left some lingering impacts and, in some areas, multiple replants. With crops struggling through emergence and the first few growth stages, we are looking ahead to see what the summer will bring. How much impact will the super El Nino have on our crops? We talk with Dr. Aaron Wilson to get an idea of what may be instore.

Episode 187 – Spring Update: Planting progress, cold damage, and more

by at

Planting season are never normal and 2026 is no exception. With the southern half of Ohio nearing completion and the northern half struggling to make headway, there was a lot of crop variability as below freezing temperatures hit the state. Expected prolonged cold and wet weather as another wrinkle. Dr. Jason Hartschuh, Field Specialist with OSU Extension, joins us as we talk about the potential impacts on corn, soybean, wheat and alfalfa. We share what to look for now and in the coming weeks as we deal with a cooler, wetter May.

This CORN Newsletter has two articles on freeze impacts to soybeans and wheat: https://agcrops.osu.edu/newsletter/corn-newsletter/2026-12. The Purdue photo gallery on freeze damage can be found at: https://www.agry.purdue.edu/ext/corn/news/articles.01/Frost_Corn_Soy-0418_Gallery.html.

Episode 185 – A Slippery Situation: Battling Slugs in Row Crops

by at

Slug pressure has become an increasingly common and frustrating challenge in crop fields in recent years, driven by wetter springs, heavy residue, and changing production systems. In this episode, we dig into why these slippery pests seem harder to manage than ever. With Kelley Tilmon joining us, discuss the limitations of traditional control options and what growers should realistically expect from different management strategies. From scouting and risk factors to cultural, biological, and chemical tools, we’ll break down what we know and how to make informed decisions when slugs start putting your stand at risk.

Episode 181 – From the Ground Up Research

by at

Two farmers, Fred and Josh Yoder, discuss one conservation focused research project developed by a group of farmers in Ohio. They are part of a multi-state, four-university effort to discover how to increase conservation adoption on farms. Our farmer-led team is working to improve real-world, on-farm performance of conservation practices to ensure they better generate the outcomes – e.g. profitability, yield stability, and protection from extreme weather events – that farmers need.

Episode 176 – Transitioning to Organic Grain Production Part 1

by at

Transitioning to organic production is not a consideration farmers can take lightly. The intensive management, restrictions on inputs and changes in marketing must be well understood. To help us wrap our heads around that process, Eric Richer, OSUE Farm Management Field Specialist, joins us to dive into the opportunities and challenges organic production presents in Ohio.
