Northwest ND

During the past two weeks (May 26-June 9), the region received rain ranging from 0.4 inch in Williston to 1.31 inches near Crosby, based on NDAWN sites. Rains have been spotty and the region is very dry. Producers are questioning their hay production and have started selling or relocating a portion of their cattle herd.

Winter wheat is jointing while many of the small grains are at the 4 leaf stage and above. Winter wheat stands have been reported as average to slightly poor stands. The same holds true for many of the crops in the region. In the irrigated Yellowstone Valley, many of the fields had to be irrigated which made for poor stands in all crops as well. Field pea leaf stages have been reported up the 7-9 node stage. Other warm season crops are just getting a good start. Alfalfa harvest should begin within the next 10 days if wanting the good quality hay.

Cutworm infestations in small grains and legume crops have been reported throughout the region. Small grain herbicide applications have been going for the past couple of weeks.

During the past week (June 4 to 10), the region received rain ranging from 0.9 inches at Harvey to 2.5 inches at Edgeley, based on NDAWN (North Dakota Agricultural Weather Network). Rainfall during the past two weeks has helped maintain good yield potential in small grain and other cool-season crops, and significantly helped plant stands of row crops.

Winter wheat is beginning to head, and spring wheat and barley are in the 4-leaf to jointing stages. Corn development continues to be slowed by cool temperatures. For example, corn planted on May 1 at Carrington is behind about 150 growing degree day (gdd) units compared to the 5-year average while gdd units at Oakes are about 50 less.

Small grain POST herbicide application is nearing completion, while corn treatments are beginning. Wind and rain are currently hampering herbicide application. Tan spot is becoming more common in all wheat due to the current wet period. Farmers still applying herbicides for weed control in wheat may want to tankmix a foliar fungicide. For example, at the Carrington Research Extension Center last year, three trials with an early-season fungicide application averaged 2 bushel/acre (4 percent) greater yield compared to the untreated check. Winter wheat should continue to be monitored for virus and leafspot disease, especially leaf rust; and row crops for cutworms.
