  1. Ag Crops Team at FSR

    The Farm Science Review will be held again this year at the London, Ohio location. Dates are September 19, 20 and 21. See http://fsr.osu.edu for more information. Harvest has not quite stared yet so you should have the time to check in.

    The Agronomic Crops Team (http://agcrops.osu.edu) will once again be welcoming visitors on the east side of the grounds between the parking lot and the exhibit area.

  2. Will Planting Delays Require Switching Corn Hybrid Maturities?

    Author(s): Peter Thomison

    According to the USDA/NASS (https://www.nass.usda.gov/Statistics_by_State/Ohio/Publications/Crop_Progress_&_Condition/2017/cw2117oh.pdf), for the week ending May 21, corn was 73 percent planted, which was 24 percent ahead of last year and the same as the five-year average.

  3. Delayed planting effects on corn yield: A “historical” perspective

    Author(s): Peter Thomison , Author(s): Allen Geyer

    According to the USDA/NASS (https://www.nass.usda.gov/Statistics_by_State/Ohio/Publications/Crop_Progress_&_Condition/2017/cw2117oh.pdf), for the week ending May 21, corn was 73 percent planted, which was 24 percent ahead of last year and the same as the five-year average.  However, at this time, it is unknown what percent of the earlier planted corn has been or will be replanted due to excessive soil moisture, freezing temperatures and frosts, fu

  5. Slugs can’t spring, but late spring is the time to watch for them

    Author(s): Kelley Tilmon , Author(s): Andy Michel

    As planting wraps up, a reminder is in order about possible slug problems in no-till crops, especially in fields with a history of slug damage.  Although we do not know how numerous slugs are in fields, we do know that most crops are being planted later than normal.  If you have read our recommendations for slug management, you know that one way a grower can get a head start is to plant early, and get their crop out of the soil and growing before slugs begin their heaviest feeding.  However, with the weather conditions over the past month, many fields are just now being planted.  Slugs have

  6. Corkscrewed mesocotyls in corn

    “Corkscrewed” mesocotyl development causing emergence problems in corn

    Author(s): Peter Thomison

    Last week I received several reports of abnormal corn emergence. Often the problems were associated with corn seedlings leafing out underground and it’s likely weather and seedbed conditions were responsible for the occurrence of the abnormal growth. Seedlings exhibiting abnormal emergence may have a twisted appearance because internal leaves start expanding before the seeding has elongated. “Corkscrewed” mesocotyl/coleoptile development may occur when the coleoptile encounters resistance (like soil crusting or a dense soil surface) as the mesocotyl elongates.

    Armyworm in Corn and Small Grains

    Author(s): Kelley Tilmon , Author(s): Andy Michel

    In April we reported that University of Kentucky true armyworm moth counts were higher than average.  These moths migrate northward, so if our southern neighbor reported high catches, many moths also likely made it into Ohio. After migrating and establishing, armyworms begin to lay eggs in grasses, including wheat fields and cover crop fields (that may have corn planted soon). Larvae feed for about 3 weeks before pupating. This article discusses armyworm management in corn and small grains.

  9. Corn Management Practices for Later Planting Dates – Changes to Consider

    Author(s): Peter Thomison , Author(s): Steve Culman

    There was little progress made on corn planting last week due to persistent rains and saturated field conditions (https://www.nass.usda.gov/Statistics_by_State/Ohio/Publications/Crop_Progress_&_Condition/index.php).  As of Sunday May 7, 46 percent of Ohio’s corn crop was planted - only 4% more than the previous week. Moreover, according to NASS estimates, only 12% of the crop has emerged.

    Crop Walk Series

    Author(s): Amanda Douridas, CCA

    Join specialists in the field this summer to see hands on what insect and disease pressure is present. The specialists will help participants identify insects and diseases and then discuss management strategies. The series begins with a Pasture Walk on May 23 at 5:30 pm. The field borders the Ohio Caverns so an optional group tour of the Caverns has been set up at 4pm ($15).
