Fields were scouted just west of Lamar, Mo. Wheat was in the tillering stage, with a few plants starting to move into the jointing stage. Right now, we are not seeing much weed pressure, however, some henbit was found. I did not find any aphids.
Fields were scouted west of Golden City, Mo. Wheat was in the second joint. Bird cherry oat aphids were observed, but only at about one aphid per foot of row. Some Septoria was observed on lower leaves. Temperatures in the mid 30s are expected the next few nights. Freeze injury to wheat in the joint stage does not occur unless the temperatures are in the mid 20s. For sprouting corn, temperatures between 28 and 32 degrees are damaging, but can kill the plant when they fall below 28 degrees.
Fields scouted east of Liberal, Mo. The wheat looks good overall and was in the second joint stage. Catchweed bedstraw, henbit, and chickweed were observed.

One field showed heavy evidence of disease including Septoria and stagonospora. Some corn fields have not yet been planted.
