ISSUE 9 June 30, 2005
During the past week (June 22-28), the south-central region’s rainfall ranged from 0.2 inches at Linton to 1.7 inches at Harvey, as recorded at NDAWN (North Dakota Agricultural Weather Network) sites. Growers continue to struggle with timely herbicide applications in warm-season crops, fungicide application in wheat, and hay harvest. The region’s cool-season crops continue to have excellent yield potential. The majority of the region’s spring wheat crop is at heading or beyond. In addition to fungicide applications for leafspot disease control and scab suppression, some farm managers are applying foliar N to increase wheat grain protein content. Differences in wheat variety straw strength and seeding rates are becoming apparent as lodging is occurring in area fields. Corn growth is rapid and the crop will easily be at or beyond ‘knee-high height’ by July 4. During the period of May 1 to June 26 at Carrington there were about 175 greater corn growing degree day units as compared to the same period in 2004. Soybean aphids have been reported in Barnes and Dickey counties. Most soybean fields are in mid-vegetative (V3-5) to early-flowering stages (R1). On June 27 at Carrington, a soybean variety with 0.0 relative maturity began flowering. Downy mildew is present in area sunflower fields.

The region received from 2 to 4 inches of rainfall in the last week with more rain predicted. Soils are saturated and the affected acreage is increasing daily. Preventive planting acreage is considerable in Cavalier, Pembina, Walsh and Grand Forks, Steele, Griggs counties. Streams are flowing and wet areas growing. Growers are struggling with finishing up weed control as crops grew rapidly with warmer weather. Disease development in canola and small grains is a major concern as conditions for white mold and small grain leaf disease development is very good. Fungicides are being applied although it is difficult for ground sprayers due to saturated soils. Growers are also starting to treat spring wheat acreage with supplemental nitrogen for protein enhancement due to encouraging protein premiums or significant discounts. Cool-season crop development is very good. Earliest planted wheat and barley are flowering. May-planted soybean, sunflower, and dry bean are progressing well. Downy mildew in sunflower is very common. The sunflower beetle adult population seems to be below average this year. Earliest canola is at peak bloom and at least half of the canola acreage will either be blooming or begin bloom the next week. Some Flax is blooming and later plantings are being sprayed for weed control. The earliest-planted corn is 2-ft tall or greater. Winter wheat is through flowering and into kernel development. Leaf rust is common in Nelson county and parts of Walsh county, and starting to show up in other regions.

Rainfall over much of the area this past week has delayed hay harvest and herbicide/fungicide applications. This past week (June 21-28), Beach had the greatest amount of precipitation at the NDAWN site with 2.18 inches reported while Hettinger had the least at 0.67 inches. Reports from other locations indicated that greater amounts were received early this morning (June 29) from the Haliday area with up to 4 inches received. From the first of the month to this morning, Dickinson has received 6.39 inches. The record was set in 1947 when 9.02 inches fell in the month of June. Since 1897 when records began to be kept at Dickinson, June precipitation has surpassed 6 inches 10 times. The highest wind gust recorded at Dickinson for the month of June was 75.9 mph. Hail and wind have caused damage in some of fields. Many fields appear to be doing well.
Winter wheat has completed flowering and is in the milk stage. Early-seeded spring wheat is heading to early flowering while canola and field peas are flowering. Early seeded barley has headed. Scouting reports indicate tan spot and rust are prevalent in many wheat and durum fields. Haying began a couple of weeks ago but weather has been less than ideal for getting the hay baled and off the field. Producers who have been able to get their hay cut and baled appear to have a good chance of getting a second cutting.
Field Days for the Research and Extension Centers in southwest North Dakota will be held on Tuesday, July 12 at Hettinger and on Wednesday, July 13 at Dickinson.
This year marks 100 years of service to the State of North Dakota by the Dickinson Research Extension Center. This year’s afternoon Management Tour (begins at 1 PM) at the Dickinson Research Extension Center on July 13 will focus on Forage in Rotations. Dr. Martin Entz, University of Manitoba and Dr. Dwain Meyer, NDSU, will be featured speakers at this tour. Martin is an internationally known researcher and speaker. He will address the use of forages in making cropping systems economically viable. Dwain Meyer, an expert in alfalfa production, will discuss alfalfa termination, establishment, and management. Other speakers and topics include Dr. Pat Carr, DREC station agronomist on annual forages as well as Bridget Johnson and Ron Wiederholt, nutrient management specialists on utilizing manure in corn production. Activities are planned for producer participation. Individuals interested in the afternoon tour should call our office at 483-2348 to save a place on the bus. The traditional small grains variety tour will start promptly at 8:30 AM. In addition, a horticulture tour is available with Ron Smith, NDSU Extension horticulture specialist at 3:00 PM. Further information about the tours is available at the DREC web site, http://www.ag.ndsu.nodak.edu/dickinso .
