I have been in a few wheat fields recently and they are beginning to reach a stage of growth that we need to consider herbicide applications. Here is a couple pictures I took in an area wheat field:
In this picture you can see a few different broadleaf weed species and ryegrass are beginning to emerge in planted wheat.
Here is a picture of a wheat seedling and a ryegrass seedling that had emerged in the field. I am beginning to find ryegrass emerging around the edges of fields and around obstructions in the field.
Growers should consider making herbicide applications to their wheat now rather than later as they will be much more successful if they treat weeds while they are small.
