  1. Head Scab Risk has Increased Across Ohio

    Author(s): Pierce Paul

    Due largely to rainfall, high relative humidity, and warmer temperatures over the last several days, the risk for head scab is now moderate across most of the state of Ohio, and high across the south. The risk is low in NW Ohio. This would be the time to apply a fungicide to control head scab and reduce the risk of grain contamination with mycotoxins as fields reach anthesis in the northern third of the state. Even fields in the lower half of the state that flowered 5-7 days ago could benefit from a fungicide application.

  2. Will Upcoming Cool Temperatures Hurt Winter Wheat?

    Author(s): Laura Lindsey

    The short answer, probably not.

    Low temperatures may dip to low 30s/high 20s in northern Ohio over the next few days. However, these temperatures should not harm winter wheat at the Feekes 6 to 7 growth stage. [As a side note, I wrote this exact article last year at this time. Temperatures in Ohio were in the low 30s to upper 20s in northern Ohio, but wheat yield ended up being record-high for many famers due to the long grain fill period. Last year, there was even snow on some fields.]

  3. Reminder to Attend the Wheat Refresh and Field Walk

    Author(s): Amanda Douridas

    On March 30, we’ll walk a wheat field with Dr. Laura Lindsey who will show us how to evaluate the field coming out of winter and refresh growth staging the wheat. Growth staging is critical for nutrient and crop protection applications.

  4. Yes, Another Article About Freeze Symptoms in Winter Wheat

    Author(s): Laura Lindsey

    After a (short) second round of winter last week, there has been some concern regarding winter wheat. As a reminder, the magnitude of freeze damage depends on: 1) temperature, 2) duration ofFigure 1. Photo credit: JD Bethel temperature, and 3) wheat growth stage. During the cold snap last week, the majority of winter wheat in Ohio was at the Feekes 6 to 8 growth stage.

  5. Should you expect any freeze damage to winter wheat? Most likely, no.

    Author(s): Laura Lindsey , Author(s): Alexander Lindsey

    The incoming cold temperatures are not likely to impact winter wheat. The magnitude of freeze damage depends on: 1) temperature, 2) duration of temperature, and 3) wheat growth stage.

    Prior to the Feekes 6 growth stage, the growing point of wheat is below the soil surface, protected from freezing temperatures. Most of the wheat in Ohio is at the Feekes 4 (beginning of erect growth) or Feekes 5 (leaf sheaths strongly erect) growth stage and should be unaffected by the incoming cold temperatures, predicted to be mid- to low 20s on Wednesday and Thursday.
