Episode 171 – All in on Harvest Data – Part 1

by at

Farmers write some big checks based on harvest data. How confident are you in the quality of that data? We’re getting into the weeds with Dr. John Fulton about how to ensure confident decisions can be made based on what is collected in the field this fall. In the first of this two part series, we talk about how yield measurements are collected in the combine, provide advice on calibration and discuss how unintentional mistakes can lead to big missteps with input decisions.

Episode 169 – Tar Spot in 2025

by at

Tar spot concern continues to grow across Ohio as it shows up in more and more fields each year. Each year farmers and researchers wonder if this will be the season it really explodes, causing widespread economic damage. For a background on Tar Spot, check out episodes 123 and 101.

In this episode, Dr. Stephanie Karhoff updates us on the latest research and treatment recommendations for managing not only Tar Spot but Gibberella ear rot and the vomitoxin it causes. Each disease has certain weather conditions and infection timing that are critical components to successfully managing it in field. The Crop Protection Network’s disease forecasting tool can afford insight into what to look for during scouting: https://cropprotectionnetwork.org/crop-disease-forecasting.

Episode 165 – Which to plant first?

by at

Each planting window brings the same question- Should I plant corn or soybeans first? Perhaps you have heard it referred to as the Battle for the Belt. Dr. Osler Ortez joins us for an update on his research based competition with soybean specialist Dr. Laura Lindsey to determine when the best windows are for planting corn and soybeans. They are also looking at where the largest yield losses occur when planting is delayed. These results can help farmers make decision on when to switch between corn and soybeans based on the calendar, maturity and conditions.

Episode 161 – UAV Cover Crop Seeding

by at

Dr. John Fulton and Alex Thomas share the latest on utilizing drones to seed cover crops. They have done extensive research evaluating seeding capabilities, timing and stand establishment and share the results with us. We also talk about what it takes to become a licensed UAV operator, the challenges and advantages of seeding with UAVs and the future of availability considering tariff restrictions.

Episode 159 – Preparing for Spring Weed Control

by at

Dr. Alyssa Essman gives us the rundown on which weeds we need to watch for (hint- it’s still waterhemp) and management strategies for success. We talk about some cost effective options that still allow for a diverse selection of herbicides to mitigate further resistance development. Over the top application of dicamba is still illegal so we asked her about that as well. Tune in for insight as you make preparations for spring.
