Freezing Temperatures and Wheat

Freezing temperatures occured April 7, 2009 across parts of Kentucky. More freezing temperatures are expected tonight. Wheat in many fields is close to jointing, if not slightly past. Temperatures need to approach 24 degrees F or less before severe damage occurs on wheat that is jointed.

After about five to seven days of good growing conditions, we will have a much better idea of how the wheat survived. However, based on most reported night temperatures, we suspect that most of the wheat will have some leaf damage but no severe damage to yield potential.
