Southwest ND (06/06/19)

Information from the Southwest region of North Dakota.

As conditions in the region dry down, there is much activity in the fields. Many are spraying and there are still acres that need to be planted. Many are working on sunflowers and there are still some wheat acres going in. The heat we’ve received has really helped the crops take off but has also pushed the insects along as well. There have been reports of pea leaf weevil damage in the region. Look for the crescent shaped notches on the clam leaves. Pea leaf weevil larvae can feed on root nodules and stop the plant from fixing nitrogen. More info can be found in the NDSU Extension Pea Leaf Weevil publication.

Also, be sure to scout canola fields; flea beetles have been very active over the past week. With the colder temperatures, and in some cases snow in May, some of the canola has been delayed in growth and is still in the seedling stage. Over the past week some have received small amounts of rain and there were some patches of hail. From May 28th to June 3rd , Dickinson received 0.05 inch of rain with a small rainfall event on June 3rd. Over the same period, Bowman and Hettinger received 0.02 inch and Beach, Mott, and Carson received no rain. Temperatures have been hot with temperatures in the 80s, the soil is drying out fast and more rain will be needed soon.
