Agronomy Talk: SPRING FREEZE DAMAGE TO WINTER WHEAT

Author: Steve Gauck

Cold weather prevents wheat plants from breaking dormancy, so in cold springs, wheat crops may be slow to greenup. Delayed greenup is less concerning than cold damage to the wheat crop.

Chilling injury is only one part of the evaluation of winter wheat in the spring. If the fall was wet and challenging, there could be stand establishment concerns. In some low areas, the seed may have rotted in the fall. If the plant has fewer than three developed leaves going into the winter, it is more prone to injury as the crown is underdeveloped.
