Predicted Cold Temperatures Should not Impact Wheat

Cold temperatures (30 to 32 degrees F) are predicted across the state of WI for Friday and Saturday mornings. Our winter wheat plots at Arlington and Lancaster WI are arguably the most advanced in the state. Last night (5/5/10) the most advanced winter wheat varieties were in the late Feekes 7 (2-3 detectable nodes and just prior to flag leaf emergence) growth stage. Based on these grow stages the winter wheat crop should be safe down to 28 degrees F. For more detailed information please see "Know Your Wheat Growth Stage to Predict Cold Injury".
