North Central ND (07/19/18)

Information from the North Central region of North Dakota

Over the past week, Berthold received 1.04”, Bottineau 1.22”, Crosby 0.51”, Garrison 0.50”, and Rugby 0.22” of precipitation.  Soil temperatures (bare) appear to be holding steady at most NDAWN stations in the North Central region (NCREC/Minot - NA˚F, Berthold 76˚F, Bottineau - 72˚F; Garrison - 76˚F; Rugby - 73˚F).  Please be advised that the Minot NDAWN station has not been accurate the past couple weeks.  If using the disease forecast models – I would refer you to the next closest NDAWN station for forecast information.

Pea aphids are being reported in pulse crops in Ward County.  Always consider economic threshold before spraying to help protect pollinators and other beneficial insects.  Scouting should be completed by examining the number of aphids per plant tip when 50-75% of the crop is flowering.  Check at least five 8-inch plant tips from four different locations in the field.  Calculations should be taken by determining an average of the four locations scouted.  For chickpea, there is no recommended threshold for aphids.

As a reminder, continue to scout for pests that have been reported the past couple weeks, such as small grain aphids (i.e. Greenbug, Bird Cherry Oat Aphid, and English Grain Aphid).  Populations above the threshold could result in economic injury.  Furthermore, wheat midge continues to be detected in traps across the region with numbers now falling from their peak a few weeks ago.  However, scouting should continue for a couple more weeks.  Ascochyta is also being reported in pulse crops in the area and, as a result, fungicides are being applied. 

Just a reminder – some off station field tours will take place this week.  The Renville-Bottineau Field Tour will take place the afternoon/evening of July 19th west of Mohall.  The McLean County Field Tour will occur Friday morning (July 20th) east of Garrison.  Please check each respective NDSU County websites and Facebook pages for further information.
