Dew Point Temperature and Frost Point Temperature The temperature at which the change of state occurs as the air is cooled is called the dew point temperature when the change of state occurs at a temperature above freezing or the frost point temperature when the change of state occurs at a temperature below freezing.

The bottom line on diagnosing the severity of frost or low temperature injury to corn or soybean is that you generally need to wait three to five days after the weather event before you can accurately assess the extent of damage or recovery.

In the colder months frost develops as the temperature decreases to below the frost point, which is essentially equivalent to dew point but at temperatures below freezing. If dew forms, frost formation is unlikely, even if the temperature drops below freezing. Frost is more likely to form on surfaces above the ground first,

Title: Enhancement of Freezing Tolerance by Frost Temperature Involves Complex Biological Mechanisms Technical Abstract: Previously-cold-acclimated plants can acquire an additional 3-5 C of freezing tolerance in LT50 tests when exposed to a frost temperature of -3 C for 12-18 h. This treatment replicates the...

However, if the temperature drops far enough for the plant cells to freeze, non hardy plants will die. Weather conditions can bring about a frost, even in supposedly frost free areas. It is important to heed the warning when your local forecaster announces 'a chance of frost', and take precautions to protect your garden.
