Northeast ND

The area received from 2.5 inches to 8 inches of rainfall the last ten days. The greatest rainfall amounts were in western Benson, Rolette, Towner and Pierce counties, and the least was in Grand Forks county. Some crop was lost in areas where water ponded and some soil crusting can be expected. Streams are full from rainfall runoff. Small grain, corn, peas, and canola plantings are complete in the region. Earliest planted corn is near the four leaf stage with most corn emerged. Frost damage to corn and emerged soybean occurred over the last weekend. It does not appear that acres will have to replanted. Weed control is a concern as fields are too wet or weather has not been conducive to apply herbicides. Growers still have soybean, sunflower and dry beans to plant.

Winter wheat is in second joint and is in excellent condition. Many growers have finished applying herbicides in winter wheat. Winter wheat flag leaf emergence will be around the first of June. Earliest plantings of wheat and barley are in the four to five leaf stage with most having at least emerged. Leaf disease levels have been low to date but would expect tan spot to increase following the moisture the past few days. Canola is emerging to 4 leaf stage. No significant emergence of flea beetle has been reported. Wild oat and broadleaf weeds are emerging and growers will be starting post emergence weed control as soon as the soil dries.

South-Central ND

Initial rain that was received during the week of May 20 was appreciated but it can stop anytime! During the past week (May 23-29), the region received rain ranging from 0.5 inch at Fingal to 3.2 inches at McHenry, based on NDAWN (North Dakota Agricultural Weather Network). A light frost occurred on May 25 that damaged some crops, most noticeably corn, but regrowth will occur as the growing point is below ground.

Spring wheat and barley are tillering and corn is in the 2- to 4-leaf stage. Little planting progress was accomplished during the past week. The regionís planted soybean acres are probably near 75 percent, and sunflower and dry bean at 25 to 50 percent. When soil and weather conditions are favorable, farm activities will include completing row crop planting, continuing POST herbicide application in small grain and corn, and alfalfa harvest. Reported pest problems have been limited to tan spot in wheat.

Southwest ND

Rainfall this past week has delayed completion of seeding sunflower and late season cereals. Precipitation received ranged from Beach with 0.49 inches to Hettinger with 2.62 inches. To date (7:30 AM, May 30) Dickinson has received 2.91 inches of rain for the month of May and expectations are that we will continue to get additional precipitation during these last two days of May. Long term (1897-2006) average precipitation for the month of May at Dickinson is 2.29 inches. Between the rain and wind this past week only portions of two days were suitable for applying herbicides and fungicides.

Wet weather has brought on tan spot in winter wheat as well as spring wheat seeded into last yearís wheat fields. Winter wheat is jointing and early planted spring wheat is about the 5.5 to 6.5 leaf stage of development. Hail damaged some winter wheat fields this past week breaking off the main stem. Tillers on these injured plants should continue to develop and provide a reasonable grain yield. Alfalfa is beginning to bud and has grown to a height of about 24 inches. Some of it is beginning to lodge. Harvest will need to begin soon if the full yield potential of this yearís crop is to be captured. Corn is mostly emerged but with cool, wet weather conditions, most of it appears chlorotic. In some local areas freezing conditions during this past weekend injured leaves or froze off top growth in corn. These plants should recover.

Downy brome has been found in fields where herbicide burndown was not done or was done early prior to emergence. Some of these plants are very robust and too late to control in crop with available herbicides. Including broadleaf crops in what currently are intensive cereal rotations will allow producers to control weeds like downy brome with more effective in crop herbicide products at a lower cost.
