Northeast ND (06/18/15)

Information from the Northeast region of North Dakota.

With mild week for weather, the small grains are looking good to excellent.  The earliest seeded fields are at heading stage in barley and spring wheat.  Across the landscape, we do have some field yellowing from nutrient deficiency.  If using soil or tissue testing for nutrient deficiency determination, the value of taking a good and poor samples for comparison is huge.  Just do it.

The mild weather has the Langdon area still at risk for stripe rust and the IPM scouting program has found infections in our region.  These lesions do not look like typical stripe rust look of a yellow stripe if you googled stripe rust images, but are spaced out lesions on the leaf (see previous Crop & Pest Report).  Closely monitor the flag leaves for lesions, which if observed will warrant a fungicide application.  The scout also found the first wheat field with grain aphids.

The tail-end of seeding is occurring in previously wet or frosted areas.   Row crops are in variable conditions depending on planting conditions and in-season excessive rainfall.  Now is the time to scout fields for planter performance on emergence and seed spacing.  We can’t control the weather, but we can control how we seed our fields.
