  1. Evaluating your Corn for Ear Rots this Fall

    Author(s):
    Jason Hartschuh, CCA, Pierce Paul, Stephanie Karhoff, CCA/CPAg

    As silage harvest finishes and corn grain harvest begins around the state, we are receiving reports of multiple ear rots, sprouted corn, and DON (vomitoxin) contamination. Preharvest scouting can help you anticipate fall challenges and develop harvest and grain handling strategies. While this article focuses on ear rots, be sure to evaluate stalk quality and potential for lodging while you are in the field.

    If you missed the Green Fields Green Dollars Video Series over the summer, you are very much in luck, as the first episode of Season 3 was just released yesterday, October 5th! Rachel and Clint are back at it, discussing the agronomic and economic aspects of Ohio farming practices. In this first episode of Season 3, Clint and Rachel caught up with Madelyn Celovsky, Conservation Agronomist Educator, Michigan State University, at Farm Science Review to talk all things cover crop drone seeding!

    End-of-Season Corn Yield Forecasts for Ohio - 2026

    Author(s):
    Osler Ortez

    The last USDA Crop Progress & Condition report (week ending 9/27/26) showed that ~95% of Ohio's corn acreage was at the dented stage (R5), ~50% of corn was mature (R6), and <5% was harvested. Most of this progress was at least a few percent points behind 2025 and the 5-year average for this time of the year.

    Author(s):
    Horacio Lopez-Nicora

    National Nematode Day is observed on the first Monday of the first full week of October, which this year falls on October 5. It is a reminder of the impact that plant-parasitic nematodes can have on crop production.

    Soybean Seed Quality Issues in Ohio: Diseases to Watch for at Harvest

    Author(s):
    Kelsey Starr, Laura Lindsey, Horacio Lopez-Nicora

    Not All Seed Discoloration is Disease

    Not all soybean seed discoloration is caused by disease. Seed appearance and quality can be affected by both biotic factors, including fungal and viral pathogens, and abiotic factors, such as environmental conditions, delayed maturity, and genetic characteristics. Different causes can also produce similar symptoms, making visual diagnosis difficult.

  7. Soybean Harvest Challenges: Wet Conditions, Soybean of Other Colors, and Seed Diseases

    Author(s):
    Prabath Senanayaka Mudiyanselage, Laura Lindsey, Horacio Lopez-Nicora

    During the soybean seed-filling period, timely rainfall is essential for maximizing yield. This year, however, persistent rainfall and prolonged wet conditions have created challenges as the crop approaches maturity and harvest. Soybean harvest is running later than in recent years, and growers who have begun harvesting are reporting discolored seeds.

Episode 144 – Dealing with DON
Agronomy & Farm Management Podcast Episode 144 – Dealing with DON

There is nothing more frustrating than getting rejected at the elevator due to high vomitoxin (aka DON) levels. DON is produced by a fungi produced on the ear and is usually infected at the time of pollination. To give farmers a better perspective of what happens behind the scenes at a grain elevator, we interview 3 grain merchandisers on their process when DON test levels start creeping up. Jason Beckman (Poet (https://poet.com/grain) ), Lisa Mitchell (Gerald Grain (https://www.geraldgrain.com/) ), and Seth Miller (The Anderson (https://www.andersonsinc.com/) ) take us behind the scenes of their operations to look at testing, grain flow and market impacts. We end with some quick reminders about DON management and to check the C.O.R.N. Newsletter (https://agcrops.osu.edu/newsletter/co...) for updates and research on corn fungicide and disease.

Agronomy & Farm Management Podcast Episode 146 – Agrivoltaics

Agrivoltaics is combining agriculture and solar energy production. In partnership with Savion Energy, we were awarded a Department of Energy grant to investigate the feasibility of forage production, grazing and impacts on solar health at the Madison Fields solar site near Rosedale, Ohio. In this episode we share the details of the project and what we have learned so far in our first growing season. You can follow along on our progress at Energize Ohio (https://energizeohio.osu.edu/farm-ene...) . To find details on upcoming field days, please visit: https://agcrops.osu.edu/events.
