ISSUE 6 June 8, 2006
Rainfall continues to be erratic with some areas receiving about one inch of rain this past week. An area centered on western Walsh county has received little rainfall the last month and plant growth in sandy areas is starting to be affected. Producers in the wettest areas are still planting a variety of crops but most areas have finished seeding and are now concentrating on weed control. Winter wheat is now starting to head and flowering time fungicide applications are beginning on fields with good yield potential. Leaf disease remains low with biggest problems occurring with wheat planted on wheat ground. First pustules of leaf rust were found June 6 in Benson county. Earliest spring wheat is now jointing with most plantings are in the three to four leaf stage. Corn is mostly 5-6 leaves. First true leaves starting to emerge in sunflower, soybeans and dry beans. Canola is from two the two leaf to six leaf stage. Weed control is on going in soybean and canola. Flax is emerging to 3 inches tall. Insect problems remain low. Soil crusting has been occurring in areas of heavy rains and producers have been harrowing to break up the crusts. Last planted fields are going into dry seedbeds and will need some rainfall to emerge uniformly.

During the past week (May 31-June 6), rainfall recorded at NDAWN sites located in the region ranged from 0.8 (Linton) to 0.1 (Streeter and Valley City) inches. Additional rainfall generally is welcome west of Hwy 281. Based on NDAWN estimates, the region’s average daily water use on June 6 was about 0.3 inches for wheat and 0.2+ inches for corn and soybean.
Crop planting is essentially complete. Growth and development of cool-season crops and corn is in ‘high gear’. Winter wheat is flowering. Early-planted (early to mid April) barley is beginning to head and wheat has flag leaves emerging. The small grain crop is short in height, likely due to temperature and moisture stress. Corn is in the 4- to 5-leaf stage, the period when ears are initiated. Soybean are in the unifoliate to first trifoliate stages. Ground rolling for soybean should be completed by the first trifoliate stage to minimize injury to plants. POST herbicide application in small grain is completed, continues in corn, and has begun in soybean. Tan spot can be commonly found in wheat but incidence and severity continues to be low.
