FROM AROUND THE STATE
ISSUE 4 May 27, 2004
This week we saw much of the area receiving at least ½ inch of precipitation. The Hazen NDAWN site reported only 0.4 inches but Bowman and Mott reported 1.22 and 1.11 inches of precipitation. At Dickinson, 0.68 inches fell for the week. For the month to date (May 25) we have received a total of 0.83 inches. We will need substantial rains by the end of the Memorial Day weekend to push the total to the long-term average of 2.28 inches.
The effects of the mid May freezing weather are still being felt. According to Dwain Barondeau up to 90% of the canola that was seeded in Hettinger County may have been killed by freezing conditions experienced earlier this month. He expects much of it to be reseeded to sunflower. Some of the spring wheat was still recovering from freezing conditions. Producers will have more of a challenge in staging the crop since much of the early seeded crop has lost one or two leaves.
Rye is in the boot. Winter wheat is jointing. Most advanced spring wheat I have seen for the week is in the five-leaf stage. Peas are in the four to five node stage and early seeded flax (April 17 planting date) is a couple of inches tall.
We are still receiving reports from producers of cutworm damage. One producer in the New England area indicated a field of alfalfa was not greening up. He scouted the field and found 5 to 6 cutworms per crown. He sprayed and shortly the field greened and is actively growing. In a mustard field that was newly emerged, cutworms had nearly destroyed the entire field. Cutworms were ¼ inch to ½ inch in size and moving to the adjacent wheat plantings. Fully mature Army cutworms will grow to 1 ½ to 2 inches in size before they will pupate. The size of the cutworms found out in the field would indicate they have the potential for feeding another week. Producers should continue to scout fields for cutworms.
Disease – Tan spot infections are very light but with recent rain, producers should expect the incidence and severity of the infections to increase. Rain is expected over the Memorial Day weekend.

Three rainfall events the last eight days delivered 0.75" to 1.25" precipitation throughout the area. Very little field work occurred north of highway 17. Some planting of sunflower, and soybean was accomplished along highway two and in the Red River Valley. About 20% of small grains acreage, 50% of the Canola and most of the warm season row crops are yet to be planted in Cavalier, Towner and Rolette counties. Most cool season crop acreage is planted and about 30 percent of warm season row crops are planted south of highway 17. Average temperatures in the mid 50's last week resulted in very little crop or weed growth last week due to continued extreme cold. Small grains are emerging to 2.5 leaves. Canola is emerging to 2 leaf Corn, generally, is just emerging. Wild oat emergence has occurred and spraying for this weed will start in 7 to 10 days. Winter wheat continues to look very good.

During the past week (May 19 to 25), the south-central region’s rainfall ranged from 0.35 inches at Oakes to 1.1 inches at Pillsbury as recorded at NDAWN (North Dakota Agricultural Weather Network) sites. Most of the area received 0.5 to 1 inch of rain. Topsoil moisture generally is adequate but additional subsoil moisture is welcome.
The region’s cool-season crop and corn planting is complete. Most wheat is at the 2- to 4-leaf stage and timely-planted corn is in the 1- to 2-leaf stage. Previously-frosted corn is well recovered. The majority of soybean have been planted and remaining acreage should be planted by Memorial Day. Dry bean and sunflower planting continues.
POST herbicide spraying for wild oat and early-emerged broadleaf weeds in small grain continues when the weather cooperates. Weed emergence and growth is accelerating with the recent rainfall and warmer air temperatures. Other pest problems currently appear minimal. Some wheat streak mosaic has been found at the Carrington RE Center in volunteer winter wheat and traces of tan spot can be found in our winter wheat variety trial.
