If you are fortunate enough to have your corn and soybeans planted, you may be part of the few farmers who are done in the county. However, according to the latest Ohio Crop Weather report, only 52% of the corn is planted and 36% of the soybean field fields are planted across Ohio.
I was out staging crops [last week] and did notice some corn in the 4 leaf stage, but most soybeans that were up were VE emergence stage or VC cotyledon stage. Some wheat has flowered in earlier planted fields. We are definitely behind compared to last year and also compared to the 5 year average because of the cool spring and rain. As you get fields planted and think about nitrogen application to corn or fungicide applications to soybean or corn, you might consider cooperating with OSU Extension with on-farm research. Currently, I have both black cutworm, true armyworm, and European corn borer traps set around the county that I have been monitoring. So far, weekly catches of adult moths have been low. Soon I will be setting western bean cutworm traps, which is a pest of corn. So let me know if you are interested in having a trap near the edge of one of your corn fields.
There is a Beef Quality Assurance certification training set up for Tuesday, May 31 at the Extension office starting at 7:00 pm. Beef Quality Assurance training is for beef cattle producers, needing to recertify or certify to sell cattle at auctions and other markets. Many of the major beef processors, auctions, and other markets began requiring producers to have a BQA certificate at the beginning of 2019. Beef Quality Assurance certification is for a period of three years and was previously held in Kenton in December 2018 and February 2021. Several local producers need to recertify in addition to any cattle producers who need to gain BQA certification for the first time. Certification can also take place online at https://www.bqa.org. Register for this Kenton training at https://go.osu.edu/HardinBQA or call 419-674-2297. Registration is required and space is limited for this local no cost in-person training that is good for both initial BQA certification or recertification. See the attached news release and flyer for more information.
The online Summer Northwest Ohio Agriculture Newsletter is now available for reading. It includes events including programs, meetings, and field days being held in our part of the state.
LEP MONITORING NETWORK UPDATE
True Armyworm vs Fall Armyworm, Trap Count Updates - Amy Raudenbush, Suranga Basnagala , Kyle Akred, Mark Badertscher, Lee Beers, Alan Leininger, Clifton Martin, James Morris, Eric Richer, Beth Scheckelhoff, Cindy Wallace, Curtis Young, Andy Michel, Kelley Tilmon
True Armyworm vs Fall Armyworm— We all remember last year’s outbreak on alfalfa and forage from fall armyworm. Many growers are hearing “armyworm” again, and are worried about infestations in corn, wheat, oats and other small grains this spring. Keep in mind that we have two completely different species of armyworm: True (or common) armyworm (Mythimna unipuncta) usually occurs in the spring. Infestations are typically found in wheat or oats, before marching onto corn and turf later in the season. Read more at https://agcrops.osu.edu/newsletter/corn-newsletter/2022-15/lep-monitorin...
LOW HEAD SCAB RISK ACROSS OHIO
Pierce Paul
Wheat is, or will soon be, flowering in parts of central and northern Ohio. After a relatively slow start to the season, several days of warm weather caused the crop to advance, reaching anthesis (Feekes 10.5.1) a few days earlier than usual in some locations. Feekes 10.5.1 is the growth stage at which wheat is most susceptible to infection by the fungus that causes head scab and produces vomitoxin. However, according to the FHB risk tool (www.wheatscab.psu.edu), fields across the state are currently at low risk for head scab.

REPLANTING DECISIONS IN CORN AND SOYBEANS
What to Consider - Osler Ortez, Laura Lindsey, Alexander Lindsey
Early plantings, cold air and soil temperatures, precipitation, wind, and warmer temperatures during or after planting may lead to reduced stands in planted fields due to factors such as imbibitional chilling, frost damage, soil crusting, and standing water. These factors (or combinations of them) can negatively affect seedling vigor, plant growth, crop establishment, and plant stands. Reduced stands may result in lower yields. If reduced stands are a concern, a potential solution is to replant fields. However, before replanting, make sure you read this article at https://agcrops.osu.edu/newsletter/corn-newsletter/2022-14/replanting-de...
SOYBEAN PLANTING PROGRESS AND VEGETATIVE GROWTH
Laura Lindsey
Cool, wet weather in April and early May delayed soybean planting progress; however, with some warmer and drier days, soybean planting was 18% complete by the second week of May. Soybeans that were planted the end of April or first week of May are likely at the VC growth stage or will be at the VC growth stage soon. There are several common misconceptions about soybean plants at the VC to V3 growth stage.

UPDATE OF CORN NITROGEN RECOMMENDATIONS
MRTN – Greg LaBarge
This article provides an updated Maximum Return to Nitrogen Rate recommendation table for corn planted after soybean. There are a couple of changes to note with these revised tables. First, due to continued concerns about nitrogen source availability, urea was added to the source list to provide per unit N prices. In addition, a nitrogen rate quick lookup table is updated to reflect new data in the Corn Nitrogen Rate Calculator tool. The database for soybean-corn and corn-corn rotations now includes trials through 2021.
