Scouting for Freeze Injury
Last night, April 10th, 2020, some areas in North Carolina experienced temperatures in the mid to low 30s and some even had a light frost. Please use the Scouting for Freeze Injury in Winter Wheat factsheet to assess injury over the next two weeks. If your wheat sustained injury you will start to notice 5-7 days after the freeze event. Most North Carolina wheat is at the flag leaf stage or beyond and many earlier-maturing varieties are already heading and flowering. Significant freeze damage at the flag leaf and heading stage usually requires sustained temperatures below 30 degrees Fahrenheit. However, we may see low levels of injury for wheat that experienced temperatures in the low 30s for several hours.
