In partnership with Texas A&M AgriLife Extension small grains specialist Dr. Fernando Guillen-Portal (979) 845-4826, fernando.guillen@tamu.edu, Soil & Crop Sciences AgriLife Extension brings you this update.

National Weather Service has issued a series of freeze watches/freeze warnings/hard freeze warnings in Texas generally from Paris to Weatherford to Abilene to Seminole and all areas north.  Some temperatures in the northwest Texas South Plains and Panhandle are predicted to drop into the mid-20s on Wednesday morning.

The vulnerability of wheat to a combination of freezing temperature, its duration, and other factors (canopy closure, lack of soil moisture, position in the landscape like low areas, wind) will determine the actual impact.

http://wheatfreezeinjury.tamu.edu has the information you need to share with inquiries and refer concerned growers to.  On the right side is a link to “Wheat Freeze Injury in Texas” (ESC-026).  This includes how to assess freeze damage in Texas wheat and other small grains, which often involves splitting the stem to find the growing point.

The chart below from Wheat Freeze Injury in Texas catalogs the temperatures at which we may anticipate injury. 



Please refer inquiries to the above website.  Contact your regional Extension specialists if you need help with producer questions.
