Northeastern ND

Favorable weather has continued to dry soils and allow rapid planting. Planting of small seeded oil crops and small grain is nearly complete. Some pockets that received late fall rains are struggling to finish small grains. Most areas are now finishing soybean, sunflower and drybean seedings. Rainfall amounts Tuesday morning were highly variable, ranging from 0.1" to 0.6". Higher rainfall amounts were ideal for dry seedbeds, especially small seeded oil crops that were shallow seeded into dry soil and having problems with emergence.

April-early May plantings of small grain and canola have emerged, with some reaching the two leaf stage. Corn has just begun to emerge in the region. Dense wild oat stands showed up this week. Last week’s strong winds caused some unprotected plantings to have stand losses. Seedbed and subsoil moisture is generally adequate throughout the region. Flea beetles emerged this week in large numbers.

South-Central ND

Crop planting should be near completion by the end of May throughout the region. Exceptions are some area fields that need replanting and in Sheridan, Wells, and Eddy counties where planting will continue in early June. Small grain stands generally are excellent and growth stages range from emerging to tillering. Winter wheat is jointing. Corn emergence is slow and some fields have been replanted in the southeast. Canola and mustard have been injured by repeated frosts, wind, and more recently by flea beetle. Rainfall is needed throughout the region to replentish topsoil moisture, especially for winter wheat, early-planted spring crops, and for germination of shallow-seeded crops and soybean. Weeds are rapidly emerging and growing including wild oat, kochia, wild buckwheat, wild mustard, common lambsquarters, foxtail, and pigweed. Growers should be monitoring corn, bean and sunflower fields for wireworm and cutworm activity. Alfalfa, grass hay, and pasture growth is very slow, especially early-grazed pastures. Growers may need to start planning to supplement their hay needs by planting warm-season annual forages.

Southwest ND

Producers, county agents, and crop scouts continue to find infestations of Army cutworm in fields scatter throughout southwest North Dakota. The majority of cutworms found have been reported to be ½ to ¾ inch in length indicating that they can still cause significant damage to crops if levels of this pest are high enough. Producers have sprayed for cutworms in several locations in southwest North Dakota. Flea beetle activity in canola is increasing with temperature. Canola plant stands have been difficult to establish this year due to weather. Some producers have given up on establishing a canola stand and have replanted these fields to another crop.

Hard red spring wheat and barley seeded prior to the mid-April snow storm is now in the three- to four-leaf stage. Wheat seeded mid-May is emerging. Established alfalfa is eight to ten inches in height at Dickinson. At other locations where precipitation has been more limited and older stands, growth has been less. Corn planting is nearly complete with emergence reported of earlier sowing. Sunflower planting is well underway.

The Dickinson NDAWN locations received the greatest amount of precipitation at 1.04 inches while other the remaining locations in southwest North Dakota received 0.13 or less.
