Clean the planter with a pressure washer or high-pressure air; washing off all starter fertilizer is especially important to prevent corrosion; flush all liquid-handling systems. j Requires 15 inches of cumulative precipitation during the growing season following application. Roundup* can be applied in combination with Nortron,* Betamix, Stinger* or UpBeet, depending on broadleaf weed species, to improve control in field. Therefore, late-season control of this species can be difficult and is improbable to achieve. All pesticide use suggestions are based on the assumption that all chemicals will continue to have a registered label with the Environmental Protection Agency. Fields that are waterlogged or have poor soil structure provide favorable conditions for infection. Proper nitrogen fertilizer use increases root and sugar yield. Tolerance was detected in fields where control was not as good as expected. Use maximum Roundup* rates, even in fields with weeds with low-level resistant biotypes because 1- to 2-inch weeds are easier to kill than 3- to 4-inch weeds, and dead weeds cannot produce resistant progeny. Once the pre-commercial seed meets all of the quality requirements it is prepared for commercial production. Soil at 7.5 pH or above requires crop rotation to be extended from nine or 10 months to 17 or 18 months and from 17 or 18 months to 24 months. By mid June plants have reached full height (4 to 5 feet) with flowers starting to open. Control 1-inch glyphosate-resistant common ragweed with Stinger* at 2 fl oz/A followed by a repeat application of Stinger at 2 fl oz/A at approximately 14-day intervals. Variety trials contain experimental lines to evaluate their adaptation, productivity and quality in this area. Areas at highest risk of damaging SBRM infestations include rural Auburn, Bathgate, Cavalier, Crystal, Glasston, Grand Forks, Merrifield, St. Thomas, Thompson and Walhalla, N.D., as well as Argyle, Crookston, Donaldson, East Grand Forks, Eldred and Stephen, Minn. Drop tubes should move freely up and down. Some new planters have small rough areas on casting from the production process; file them down as necessary. Common starter phosphorus fertilizer sources and maximum amounts suggested for seed application. An Aphanomyces soil test should be done to determine if the soil is infested with Aphanomyces and the level of infection. 8. Threshold: Insecticide treatment may be justified if an infestation exceeds one Lygus bug per plant (nymphs and adults combined). A History of the sugar beet Nebraska currently ranks 6th in the U.S. in production and generally ranges between 45,000-60,000 acres planted per year, with a high of 80,000 in 2000. Apply Nortron,* Ro-Neet SB or Dual Magnum* PPI/PRE or S-metolachlor,* Warrant or Outlook* early postemergence in mixtures with Roundup* at full rates + Nortron* at 4 to 6 fluid ounces per acre (fl oz/A). The systemic fungicide thiophanate methyl (benzimidazole) has federal registration for Cercospora control and is in the benzimidazole class of fungicides. During World War I and II, the supply of seed from Europe was insufficient, which required seed companies to find a growing area in North America. All pesticide users should read and understand the pesticide label prior to pesticide use. See publication PP967 for more information on powdery mildew. 7. Growers should not use QoI fungicides to manage populations in areas with known QoI resistance. The sugar factory byproduct “waste lime” at 10 tons/acre is very effective against Aphanomyces for up to 12 years. This condition is believed to keep larvae feeding higher in the soil profile (away from tap roots and nearer to insecticide-treated soil). Any grower in an area with a history of SBRM problems should pay close attention to fly activity levels in late May through June to decide if postemergence treatment is needed. Manage glyphosate-resistant waterhemp with residual herbicides. Check the monitor eye in the drop tube to make sure it is positioned properly. FirstRate = 30-month rotation + successful field bioassay. They will feed above the soil surface if soil is excessively moist. A gene conditions fasciation of flower stalk. Species that affect valley beets are subterranean, spending their entire life below the soil surface. Incorporate insecticide granules well into the upper ¼ inch of soil. In severely infested fields, plant resistant varieties early, avoid “hilling” soil on sugarbeet crowns, increase the length of rotation and rotate with nonhost crops such as small grains. The energy is converted to fat stores in the body of the deer. Sugar beet seed should be planted between 1/2 inch and 1 inch in depth. Root maggot fly counts for the current growing season and those from previous years can be viewed at www.ndsu.edu/entomology/people/faculty/boetel/flycounts. MSO-based “high surfactant oil concentrate” adjuvants (HSMOC) contain a higher concentration of surfactant than COC and MSO, and enhance oil-soluble herbicides such as Nortron,* Betamix, Stinger* or UpBeet without decreasing Roundup* activity and, thus, should be used in tank mixes with glyphosate. After planting of stecklings, an early irrigation is done.
