Crop & Pest Report

Northwest ND (06/28/18)

Information from the Northwest region of North Dakota.

Scattered thunderstorms moved through Northwest ND Friday and Saturday June 22-23. Rainfall totals varied a lot by location with most places receiving between 0.5” and 1.5”. In southern Williams County, a strong downpour Saturday afternoon dumped 1.5-2.0” in less than 2 hours. There were small patches of hail reported from eastern MT to Minot, but no widespread damage has been reported. At the Williston Research Extension Center, the downpour caused residue washing in fields where this year’s crop is still small. Early-planted small grains are flowering and later planted small grains are anywhere from jointing to heading. Peas, lentils, chickpea, flax, and canola are all flowering and the rain and warm temperatures will push crop development this week. Growers are advised to keep an eye on their local weather conditions and be prepared to spray fungicide to control scab in their small grains. Rain, persistent morning fog, relative humidity >85%, and warm (75-85⁰F) temperatures are ideal conditions for scab infection when wheat and durum are flowering. Ascochyta has been observed in chickpea fields in Williams County and growers are advised to stay ahead of this disease with fungicide applications as soon as the crop is flowering and as long as weather conditions favor disease development.
