CROP STATUS
Significant rainfall over the past two weeks in the northern states and Manitoba have impacted field conditions as well as accelerated late season stalk and head diseases. This is especially the case in parts of northern Minnesota, southern Manitoba and parts of eastern North Dakota. Phomopsis, a stem disease, has been identified in commercial fields in Minnesota. The disease weakens the stalk making it highly vulnerable to lodging. Desiccating the field as early as possible is a management tool.
