Losses to Extreme Events: Frost/Freeze
From 1989-2018, USDA-Risk Management Agency paid just over $4 billion in indemnity payments for commodity losses due to a freeze. The risk of having frost and freeze damage is highly dependent on time of year, crop type, stage of development, and duration. Frost conditions can change within a field and are influenced by topography, with lower elevations in the field having the highest risk. The critical temperature often discussed for corn and soybean damage is 28°F for freeze damage and 30°F-36°F for frost damage, but other crops, especially specialty crops, may have different thresholds and impact. Frost damage may show some symptoms, but freeze damage may cause plant death. Frost and freeze statistics are used to calculate risk of reaching these temperature thresholds on certain days of the year. Changes to these dates for frost and freeze risk pose additional challenges to crop producers.
