ISSUE 8 June 23, 2005
During the past 30 days (May 23 to June 21), the south-central region’s rainfall ranged from 3.5 inches at Robinson to 9.6 inches at Edgeley as recorded at NDAWN (North Dakota Agricultural Weather Network) sites. Hail and strong winds injured crop in Ransom and Sargent counties on June 20. Areas north of I94 and west of Hwy 281, and south of I94 and west of Hwy 3 generally have less challenges with excessive soil moisture compared to other areas in eastern ND. Growers continue to struggle with completion of crop planting in the southeast ‘wet’ counties. Timely herbicide application in warm-season crops, fungicide application in wheat, and hay harvest are challenging most farmers.
The region’s cool-season crops generally continue to have excellent plant stands and yield potential. The region’s spring wheat crop is in the flag-leaf to flowering stages of growth. Wheat growers should be applying a fungicide during early-flowering for scab suppression and protection from leafspot disease. Aggressive farm managers are applying foliar N for increasing wheat protein content. Small grain lodging will be an increasing concern as the crop enters the grain-fill stages. Small grain aphids and barley thrips are present in the region. The region’s abundant moisture is increasing the possibility of white mold infections in flowering canola. Corn growth is rapidly accelerating with the currently adequate moisture and warm temperatures, and should easily be at or beyond ‘knee-high height’ by July 4. Soybean aphids have been reported in the Valley City area. Soybean are in the mid-vegetative stages and will begin flowering during the week of July 4.
