With the warm summer like temperatures this past week, crucifer flea beetles are starting to move out from their overwintering sites (i.e., shelterbelts, grassy areas). Flea beetles usually become active when temperature reach >68 degrees F. Flea beetles have been observed feeding on wild mustards and volunteer canola near Minot.

Some field work in the northern red river valley but else where fields remain too wet to begin springs work. Light rain on Tuesday will delay extensive field work until the first full week of May. Reports of extensive winter kill of winter wheat are starting to come in as the very cold April has delayed spring regrowth. Alfalfa health, at first look, appears to be generally good. Questions on fertilizer application amounts with the seed are common. Warm dry weather is needed to begin field work.

During the week of April 22, field work began in south-central North Dakota with fertilizer and preplant herbicide application and incorporation, and seedbed preparation. Cool-season crop seeding including small grain and canola is in progress. Black soil temperatures at the 4-inch depth ranged from the mid-50's to the low 60's F on April 30. While many area fields have moisture-saturated soils, recent warm temperatures and windy conditions have dried soil surfaces in spring-tilled fields. Rainfall is desirable for these fields to re-wet the soil surface for seeding canola or flax. Cool-season weeds are emerging including kochia and common lambsquarters, and regrowth is occurring with perennial weeds including dandelion, leafy spurge, quackgrass, thistles, and absinth wormwood.

Some winter injury has been reported in winter wheat in Sioux and Stark Counties the past couple of weeks. In one winter wheat field that was sampled, roots were washed and symptoms of root disease were found. Winter injury in alfalfa has been reported in McLean County. Established alfalfa at the Dickinson Research Extension Center on May 1 was about three to five inches tall. Alfalfa seeded earlier this spring has emerged. Crested wheatgrass pastures have greened and are growing but moisture supplies for growth are limited. Moisture under native pastures is also below normal. According to Dr. Lee Manske, Range Specialist soil moisture under range and tame perennial pastures is only about half of normal. Forage production in terms of dry matter produced from native pastures is below normal primarily due to dry growing conditions experienced throughout last fall. Even if growing season conditions are average in May through July producers can expect below normal production from range.

Early seeded hard red spring wheat and oats are emerging to the 1 -leaf stage. Seeding of the crop is proceeding rapidly. Hettinger County has seeded 25% of its wheat acreage. Canola, pea, and lentil are also being planted. Producers in the southwest counties can expect canola yields to decrease for canola seeded after May 1 and very low yields or crop failure is likely for canola seeded after May 15.

Record high temperatures (91oF at Dickinson) over the weekend and high winds have dried some soils, especially those that have been tilled. Good soil moisture conditions are still the rule in no-till fields.
