Northeast ND (08/06/15)

Information from the Northeast region of North Dakota.

Small grains harvest has fully started in the region.  Last week’s high winds caused rapid dry down of the crop.  This year, there is a wide spread of uneven maturity occurring in a field. 

Soybean aphids are present across the region.  Levels are increasing to the IPM threshold of 250 aphids/plant on 85% of plants and increasing.  Sunflowers are at risk for banded sunflower moth. The region’s sunflowers are around the best stage to control them; which is R5.1 or when pollen shed is just beginning. 

In the canola crop, blackleg and sclerotinia stem rot can found in the region.  Swathing has just started.  It’s been fairly dry for 2 weeks – great for haying, but the soybeans are starting to wilt in the light soils.  Our region could use a rain shower.
