Tar spot has quickly become a widespread concern on corn this season (2021) across much of the upper Midwest U.S. and portions of Ontario, Canada. This is especially concerning after reasonably localized epidemics resulted in low or no yield reductions over the past two seasons. This season the tar spot fungus has infected corn plants early and is rapidly increasing in many areas of the upper Midwest corn belt. The speed at which the epidemic is now moving and the crop growth stage across much of these acres (ranging from tassel to early dough) has resulted in questions about what in-season management approaches might provide an economic benefit.
Like most of the other diseases of corn, the timing of fungicide application to hedge your bets against tar spot generally is at tasseling (VT) to the silking (R1) growth stage. Recent regional research has demonstrated that while there might be little yield benefit with an application at the V6 growth stage, a single application of fungicide at VT-R1 on average can result in as much as 7 bushels or more yield compared to not treating. This is compared to just 2-3 bushels at the V6 timing and suggests that farmers are more likely to recover their fungicide costs if applying just one application at VT-R1. In the absence of tar spot and southern rust, spraying at V6 AND VT-R1 also has not resulted in economically positive returns. This practice, on average only results in an additional 1 bushel of yield compared to one application at VT-R1. There is no considerable return on investment (ROI) with two-pass fungicide programs for many corn diseases. But what about the tar spot situation this season? What do the data say about a second fungicide application to manage tar spot if I have already sprayed at VT-R1 and the disease is continuing to increase?
As we begin to approach Spring planting, it’s important to think about the intricacies of the growing season – what fertilizer to use, how much to apply, how to apply it, etc. If you’re unsure what rate would most benefit your crop while earning you the largest profit, on-farm research may be a good way for you to determine that. If you’re unsure what effects different management practices are having on the health of your soil, on-farm research may be a helpful tool. For almost any question you may have about your operation, an on-farm research trial may be a good way to better understand what the best practices may be for your farm.
This year, we plan to continue the eFields Soil Health Study that was started in 2020. In this study, soil samples are pulled from three depths: 0-4”, 0-6”, and 0-8” within a field. A variety of different tests are then performed on that soil, including routine nutrient analysis, pH, Cation Exchange Capacity (CEC), total organic matter, aggregate stability, and Permanganate Oxidizable Carbon (POXC). The results of these tests will be grouped with fields of similar management and published in the 2021 eFields book and will help to give you a snapshot of the health of your soil.
OSU Extension Paulding County is here to help you find out what’s best for your operation, whether it be through sharing of information or planning of research trials on your farm. Reach out to Sarah Noggle, Agriculture and Natural Resources Extension Educator, or Rachel Cochran, Water Quality Extension Associate, if you’re interested in doing any type of on-farm research this growing season. We will be happy to set up a trial for you to get the answers you need.
Is there a product or growing practice you want to test on your farm? If so, consider hosting an eFields on-farm research trial this year. eFields is Ohio State University’s on-farm research program. Each year, a publication is released with trial details and results. You may find the electronic version of the 2020 eFields Report by clicking here. Hard copies are also currently available at the OSU Extension Paulding County office.
Current eFields projects include the following:
- Corn Seeding Rate
- Soybean Seeding Rate
- Nitrogen Trials (Rate, Timing, Placement, & Source)
- Sulfur Rate
- Corn Pop-up Fertilizer
- Soybean Fungicide
- Soil Health
You can also work with ANR Educator Sarah Noggle to develop a custom study protocol. If you have any questions or are interested in learning more about hosting an on-farm trial, call 419-399-8225 or e-mail email@example.com.

Improving soil health (SH) can provide a variety of benefits including improved water infiltration, increased water holding capacity, and increased nutrient availability. However, it can be challenging to quantify these benefits in the field.
In 2020, the eFields program is kicking off an effort to help better understand how management practices influence soil health and ultimately water quality. OSU Extension has worked to identify a few soil tests that can provide helpful indicators of improved soil health. Though several health tests exist, we focused on tests that are simple, economical, and repeatable. We are looking for farmers interested in soil health and who want to participate in a statewide field survey collecting soil health data from fields under various management practices, specifically conventional tillage, no-till, organic nutrient management, and cover cropping. The results from this effort will be used to guide recommendations for improving soil health on Ohio farms. Soil health indicators are also being added to selected eFields trials including nitrogen rate and manure sidedress.
If you are interested in learning more about participating in eFields trials focused on soil health, reach out to your local Extension educator or email firstname.lastname@example.org. For more information about the soil health indicators and how to use them, visit: go.osu.edu/MeasureSH.
