Episode 138 – Planting Green

We caught up with Drs. Alyssa Essman and Dan Quinn at Conservation Tillage and Technology Conference to pick their brains about planting corn and soybeans into green cover crops. They share information on how to ensure good seed furrow conditions at planting and how to manage the cover crop at different stages. We also discuss herbicide strategies and advantages when planting green.

Episode 132 – 2023 eFields

Our topic for this podcast is on-farm research and the 2023 eFields report. The eFields program is OSU Extension’s on-farm research network. Ohio farmers are encouraged to learn with us by partnering to conduct trials and share data through the annual report. Elizabeth give us a summary of the 2023 report and we talk with Wayne Dellinger and Nick Eckel, county Extension Educators and fellow contributors, about projects they have conducted over the years. 

You can view the 2023 report, along with previous years, at efields.osu.edu. The Knowledge Exchange provides unique ways to sort through all eFields research projects: kx.osu.edu/efields.

Episode 127 – Corn Drydown In-field

Many areas are struggling with higher corn moisture levels than normal at harvest. While it may be tempting to leave corn standing to gain more natural drying, Elizabeth and Amanda will share why that is a high risk, low return venture.

Episode 123 – Tar Spot

If you grow or scout corn in Ohio, you have probably heard rumblings of a new disease called Tar Spot. Pictures from neighboring states to the north and west show bleak images of entire corn fields dead before their time. While researchers are still assessing the threat potential for tar spot in Ohio, it has made appearances across the state and has many farmers quite concerned. To tell us more about this new disease, Dr. Stephanie Karhoff joins us to share what she has seen and learned in her time in NW Ohio.

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 119 – Delayed Growth Stages: What does it mean for crop yield?

Some of the corn and soybeans across Ohio are upwards of two growth stages behind due to early drought conditions followed by cool weather. What does this mean for the rest of the season and ultimately crop yield? Jonah Johnson, CCA with PCT Sunrise attempts to answers those questions based on his agronomy knowledge and past experiences in the field.

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.

Episode 105 – Grain Market Update

Several unprecedented events have impacted grain markets over the past several months making it hard to know where prices may go. Andrea Flowers with Cargill in Dayton, Ohio discusses factors affecting the grain markets today. We talk about what is driving demand and where will prices go over the next few months. Andrea shares some marketing tips and what to keep our eye on as we head into harvest season. Questions for Andrea can be directed to andrea_flowers@cargill.com or 937-419-7149.

Episode 101 – Tar Spot and Other Corn Diseases

Tar spot has been found in Western Indiana. After an unprecedented outbreak in NW Ohio last year, many farmers are wondering what to expect this year, and what can be done to protect their crop. Dr. Pierce Paul, Plant Pathologist for Corn and Small Grains at OSU, shares what we know about tar spot and recommendations for control.

We also discuss the more common diseases Gray Leaf Spot and Northern Corn Leaf Blight. Listen in for suggestions on keeping corn clean this season.

Episode 96 – Do you need sulfur?

Many farmers across Ohio are adding sulfur to their nutrient bill. Research results here in Ohio haven’t revealed a strong need but deficiency symptoms and yield bumps with application do occur on occasion. So how should you approach sulfur on your farm? Elizabeth and Amanda dive into the research and share some pointers to help farmers decide the best approach for each situation.
