Weekly Crop Scouting Report

Wait 3-5 days before assessing freeze damage

Wheat in the jointing stage becomes sensitive to freeze damage at 26-27 degrees Fahrenheit. Wheat prior to jointing is not likely to be affected by frost or freeze according to Jill Scheidt, agronomy specialist with University of Missouri Extension.

“I scouted fields on April 16th west and south of Liberal,” said Scheidt. “If temperatures remain at 24 degrees Fahrenheit for 2 hours or more, the frost is likely to cause some damage. It is best to wait 3-5 days before assessing damage; you may need to wait longer if cool days follow the frost because the plants’ recovery may be slow. After 3-5 days new leaf tissue should be visible if the plant was not damaged.”

“The growing point of corn is protected under the ground until the 5th leaf stage and corn should be able to recover from a frost without any yield loss,” said Scheidt. “If the frost penetrates deep in the soil, there is a possibility of damage to the plants.”

“Wheat is at the jointing stage, if nitrogen is needed, it should be applied now in order for nitrogen to be efficiently used by wheat,” said Scheidt.

“No diseases or insects were seen,” said Scheidt.

Herbicides and insecticides should not be applied in temperatures lower than 60 degrees Fahrenheit, because plants are not actively growing and insects are not active, therefore pesticides will not effectively be taken up by the pest.
