South-Central ND

During the last week (May 10-16), the eastern part of the region received rainfall ranging from about 0.25 to 1 inch, based on NDAWN (North Dakota Agricultural Weather Network). Rainfall is needed in the western half of the region, especially Burleigh and Emmons counties. On May 12, minimum air temperatures reached 22 degrees at Streeter and 26 to 33 degrees at other NDAWN locations in the region. Small grain seeding essentially is complete. Corn planting should be completed and the majority of soybean acres planted by May 20. Growers are starting to plant dry bean and soon will begin planting sunflower. Early-planted wheat and barley fields generally have good stands and are in the 3- to 4-leaf stage. POST herbicide application in small grain will begin when bean planting ends.

Wheat response to early-season applied foliar fungicides

The Carrington Research Extension Center continues to conduct wheat disease management trials that include foliar fungicide application during the tillering stage. During 2003-05, nine trials were conducted that included early-season treatments with several labeled fungicides and rates. The trials were conducted on previous small grain ground or wheat straw was spread over the trial area if the field history was with a broadleaf crop. Averaged across the 9 site-years, wheat yield was 3.8 bushels per acre (9 percent) greater than yield of untreated checks. The best conditions for yield response with this wheat management strategy is if small grain residue (containing leaf spot disease spores) is present, a wheat variety is being grown that is susceptible to leafspot disease, weather conditions are favorable for leaf disease, and leaf disease is present on wheat leaves.

Northeast ND

Cool temperatures and rain showers in the last week slowed planting progress, especially north of highway 17 and in the eastern part of the region. Fields in the north are now generally in shape for field work and barring any more rain this week, seeding and planting of crops will be rapid. Flooded areas of the valley still remain too wet for field work. Planting progress south of highway 17 is progressing well with most corn planting nearing completion. Cool season crop planting is going well with many producers beginning soybean and sunflower planting. Earliest wheat and barley is in the two leaf stage but most is yet to emerge. Earliest planted corn should emerge this week. Weed spraying in winter wheat is occurring.
