Video: The Impact of Fall Frost at Different Soybean Developmental Stages


The impact of frost on a crop depends on how low temperatures get, how long freezing temperatures last and the development stage of the crop, among other factors. Assess crops 24-48 hours after the frost event has occurred.

Soybeans at R6 to R7 and edible beans at R8 are susceptible to frost damage. Many soybean and dry bean crops in MB have reached maturity levels that are safe from frost. However, later-seeded fields and longer-season varieties that are still green are susceptible to damage.
