Crazy that we have SNOW, but we are glad the precipitation we got was not freezing rain. Wheat is a resilient crop, and it is often noted to have "9-lives". The threshold temperature to damage winter wheat in the stem elongation phase we are currently in (Zadocs 30 to 32) is -4 degrees Celsius for 2 hours. Our agronomists are not worried about the wheat at this point of time. If you do however think that damage has occurred, you will not be able to assess the wheat for 3-10 days.
Spraying wheat is something to start considering. If spraying, you have to make sure that the temperature is above 5 degrees Celsius 24-hours before and after application. Spraying can be done until flag leaf and is recommended as the weeds are growing quickly with the warm weather we had. Fertilizer on wheat is wrapping up, with second passes now going on. Along with spraying and fertilizer, it is always a good option to add fungicide, herbicide and a plant growth manipulator on the wheat. If you crop is looking average or better, at the price of wheat right now, why would you not protect it?
