ISSUE 2  May 10, 2001


North-Central ND

Seeding of cool-season crops is progressing at a steady rate in the north central and northwest regions of the state. So far there hasn't been any major delays in field work or planting. The crop with the most substantial increase in acres in 2001 is flax. Many north central and northwest counties will see flax acres double if not triple this year.

Top soil and sub soil moisture conditions are good across the region, except for areas in Bottineau and Pierce counties where there are areas that are extremely wet. Most of the region missed the heavy rains that fell in eastern North Dakota on May 6. Canola, field peas, and small grains that were seeded the last week in April are emerging with good stands being established. Warm soil temperatures the past week have resulted in a major flush of many early-season weeds such as, kochia, wild buckwheat, winter annuals, and wild oats. Questions on pre plant or preemergence weed control options are being asked. Fertilizer supplies have been adequate so far this spring. Many questions are being asked on how much urea/nitrogen that can be safely placed with the seed of various crops.

South-Central ND

During May 2 to 8, area rainfall amounts ranged from 0.86 inches (Linton) to 2.02 inches (McLeod) as recorded at NDAWN sites. The rainfall was generally useful but caused a 4- to 7-day delay in field work. As of May 9, some field work was resuming with fertilizer and preplant herbicide application and incorporation, seedbed preparation, and seeding. Black soil temperatures at the 4-inch depth ranged from the mid 40's to low 50's F on May 8. Fertilizer supplies currently appear adequate but delays are common with custom dry fertilizer application. South of I-94, estimated small grain acreage seeded ranges from 20 to 40%. Corn planting also has begun. Early-planted small grain fields were beginning to emerge about May 1. North of I-94, small-grain seeding is about 10% complete and about 20% of the canola acres have been seeded. Winter-injured alfalfa in Emmons County and injured winter wheat in Stutsman County have been observed. Weed emergence or regrowth, including warm-season species such as foxtail, is rapid with the warm and moist soils.

Southwest ND

Seeding continues in southwest North Dakota. In some areas over half of the spring wheat has been seeded. Spring wheat that was seeded on April 25 is emerging to 1 leaf stage. Some fields are experiencing poor emergence because of dry soil conditions. Early seeded spring wheat is about 1 to 2 leaf stage. Canola is emerging. A lot of corn acres have been seeded in Golden Valley County but has not emerged yet. Some grasshopper nymphs were found in Golden Valley but no other reports on grasshopper activity have been received.

Cutworm damage has not been reported in southwest North Dakota but producers should be scouting for this pest. To often the damage from this pest is not recognized until considerable injury to the crop stand has occurred. Plants should be examined carefully for holes in plant leaves or for missing leaf tips. Missing plants are also an indication that cutworms may be present. If missing plants or holes in plant leaves are found use a knife or trowel to scrape soil away from plants to find larvae. A screen or soil sieve is useful in separating larvae from soil. Treatment thresholds are given in this newsletter by Dr. Phil Glogoza. Additional information on this pest can be found in NDSU Extension Service Bulletin E830.

Since canola is emerging and we have warm dry conditions producers should also be scouting for flea beetle.

Rainfall has been very scattered through the southwest this past week with rainfall totals reported ranging from 0 to 0.50 inches. Wind gusts of up to 55 mph were reported. The top inch of soil is drying as a result of limited precipitation and high winds. Producers are adjusting planting depths from 1 to 2 inches deep to assure adequate moisture for germination and establishment.
