Frost & Cool Temperatures

A message from our local Bayer Market Development Agronomist, Katie Macfarlane.  A few things to consider this week with a lot of fields emerging  and some cool nights still in the forecast.  ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌

‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌ ‌



Corn is less susceptible to frost injury before V5 (Corn growth staging guide) because the growing point remains below ground.

The growing point of soybeans is exposed at emergence, so they can be more susceptible to frost damage than corn (Soy growth staging guide). However, complete death of the plant usually won’t occur unless temperatures are below -2°C for several hours.
