Expect frost damage from recent cold snap (Cropland Diseases)
Description:

We are starting to receive samples that show symptoms of frost injury which are associated with the winter comeback last week. Frost damage often occurs in patches in the field, for example in low-lying areas where cold air settles. If and how severely your crop was affected by the cold temperatures depends on the developmental stage of the crop, the duration and low of the temperatures in your location. This alert discusses symptoms of freeze injury on wheat, barley, and pulse crops and includes links for further information.

Call the Schutter Diagnostic Lab at 406-994-5150 or visit our website at diagnostics.montana.edu if you have any questions about how to submit a good sample. Instructions are also on the website.

Best,
