Low Temperature Effects on Winter Wheat

Low temperatures during the early morning hours of May 9–11, 2020 may have had detrimental effects on winter wheat in some areas of South Dakota. However, cooler spring temperatures that have slowed the winter wheat development this year may have actually been beneficial to S.D. producers, as later-maturing wheat is not as susceptible to injury from freezing temperatures.
