Crop Observation and Recommendation Network

C.O.R.N. Newsletter is a summary of crop observations, related information, and appropriate recommendations for Ohio crop producers and industry. C.O.R.N. Newsletter is produced by the Ohio State University Extension Agronomy Team, state specialists at The Ohio State University and the Ohio Agricultural Research and Development Center (OARDC). C.O.R.N. Newsletter questions are directed to Extension and OARDC state specialists and associates at Ohio State.

    Starting this week until harvest, Ohio State University Extension professionals across the state will report on crop progress and field conditions. This past week, growers made significant planting progress before weekend rains, and wheat continues to mature. OSU Extension Educators and Specialists report emergence issues in earlier planted corn and soybean fields from soil crusting and in some cases slug damage.

    Most farmers in northwest Ohio finally got a planting window last week for corn and soybeans. Given the soil temperatures, crop emergence should only take a few days. Commercial manure applicators also made some progress on finally getting manure to fields.

    Many counties across Ohio are noticing slug damage in their fields this year. Slugs prefer fields that are no-till, especially fields where cover crops are grown. Slugs feed directly on the soybean, causing both seed and foliar damage that can result in complete loss of the plant. Management is difficult due to the nocturnal nature of slugs. During the day they take shelter under leaf litter and other debris in the field (Figure 1). Adding to management difficulties, slugs have all life stages present at any time in the field (eggs, juveniles and adults) (Figure 2).

    After rounding out our sixth week of monitoring for black cutworm and true armyworm, the slight decline that was seen over the past two weeks in the statewide average for both pests has continued to drop. Hardin county recorded the highest average of BCW pests last week, while Van Wert has continued to see the highest average of AMW pests this past week. These low averages indicate that we are nearing the end of the season for both BCW and AMW moths in Ohio.

    Please join Drs. Maggie Lewis, Horacio Lopez-Nicora, and Aaron Wilson on a webinar titled Weather Trends and Pest and Disease Impacts on Soybeans on Tuesday, June 25, 2024, from 8:30-10:00 am ET. We will update the latest climate trends pertinent to soybean-related pests and diseases, including increasing winter temperatures and extreme weather. We will investigate how abiotic stressors linked to global climate change impact insect pests, from changes in population growth rates to geographic range and phenology.

    Save the date! On Wednesday, July 31st, 2024, the OSU Extension Water Quality Team will be hosting their second annual field day focused on agricultural conservation practices. This year’s theme is “Cover Crop ‘Til You Drop!”, and will be focused on all things cover crops, including economics, research results, programs available for funding, as well as how this practice impacts soil health and water quality. This event will be free to attend thanks to support from Cargill and sponsorship from The Nature Conservancy.
