After the seed stalks have dried, 7-10 days later, a combine with a pickup head is used to separate the seed from the plant material. Learn how to … 7. Apply at a 5- to 10-GPA spray volume when applying alone or in combination with another systemic herbicide. If the first application is late, control will be difficult all season, even if shorter than normal application intervals are used once applications start. Student Focused. COMMERCIAL PRODUCTION OF SUGARBEET SEED. Appropriate isolation may be several miles from the nearest commercial seed production field. In storage, the quality of infected roots may deteriorate more rapidly, compared with non-infected roots. If fields are too wet, nursery is undercut and beets are pulled, topped and trimmed by hand. Sensitive isolates do not grow at all in the presence of 5 ppm of benzimidazole fungicide. NOTE: Seed treatment insecticides reportedly have failed to control springtails in the MonDak area. Recommendations for John Deere Maxi II Planter *. When a nonregistered combination is used, none of the manufacturers of the product used in the combination will stand behind its products. For more information on this and other topics, see www.ag.ndsu.edu/extension. Swathing is done best during periods of high humidity, often at night, to reduce shattering. Growing the Beets. Keep track of how many acres are seeded on a set of plates (write the date of purchase in the owners manual or on the plates). Sugarbeets treated with a nonregistered herbicide may have an illegal residue which, if detected, could cause condemnation of the crop. Beet tops can be eaten, lightly grazed or fed to animals. • Do not reduce N in zones within sugarbeet fields with yellow foliage. In general, annual grass and broadleaf control from Roundup* will not be antagonized by tank mix partners, provided Roundup* is applied at full rates. Using a rotary hoe or field harrow across beet rows in June following egg deposition can help reduce maggot numbers. The alleged failures could have resulted from extremely high infestations, or possibly could have involved a different springtail species from those that occur in the Red River Valley. Perform needed maintenance on planter prior to planting. Replace “wipers” and knock-out wheels. 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. Please attend planter test stand clinic. 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. Improperly sprayed areas become focal points for Cercospora spread. • Second, granules should be incorporated into the soil. Isolation has proven to be the best solution to keep cross- Cover crops should be killed by applying a grass-killing herbicide during the last week of May or first two weeks of June to avoid sugarbeet yield losses due to competition from cover crops for water, sunlight and soil nutrients. The rate of 45 grams of Tachigaren is recommended for fields with heavy disease pressure. i Crops with a nine- or 10-month rotation restriction require 15 inches of cumulative precipitation after application. Research in the Red River Valley, Michigan and irrigated beet-growing areas indicates 400 to 600 pounds of sugar per acre are lost as row widths increase to 28 or 30 inches. • Third, moisture is required after the application to move the chemical off its granular carrier and into the soil. Tachigaren (hymexazol) is highly effective against Pythium at lower rates and Aphanomyces at higher rates. The United States beet sugar industry has experienced great change in … Rates greater than 45 grams of Tachigaren per unit of seed may cause phytotoxicity. z For rotation to field peas in 10.5 months, precipitation must be greater than 7 inches during the 10.5 months following application and greater than 5.5 inches of precipitation from June 1 to Aug. 31 following application. During periods of dry weather, larvae feed just below the soil surface as they move along the row. 3. Apply over small, actively growing annual weeds and at the appropriate stage for perennial weeds. Land Grant. We specialize in every aspect of sugar beet seed production, from the development of new and more resistant varieties right through to the final blue seeds. They will feed above the soil surface if soil is excessively moist. More precise nitrogen management within each crop in a sugarbeet rotation will help prevent overapplication and buildup of nitrogen in the subsoil. p Barley can be planted nine months after application in Cass, Grand Forks, Pembina, Towner, Traill and Walsh counties of North Dakota. Please note the following important terminology used in this guide: • Fly emergence pertains to the initial appearance of flies emerging from soil in previous-year beet fields where they had overwintered as larvae and. Several herbicides are listed in the following table. Herbicides vary in absorption rate and in the ease of being washed from leaves. As a result of exposure to heat and dry air, the developing maggots sometimes die before hatch. If the incompatible tank mixture is applied over the crop, an uneven spray distribution may occur and result in unacceptable performance. The severity of Cercospora varies from year to year, depending on weather conditions, inoculum potential and varietal resistance. All pesticide users should read and understand the pesticide label prior to pesticide use. The vector can survive in soil or root debris. Roundup* is very water- soluble. The first fungicide application should occur when conditions first favor disease or at disease onset. 1. Frequent tillage helps reduce wireworm problems. Sugar beet seed production occurs primarily in Oregon and Washington. When conditions favor disease or disease already is prevalent, fungicide applications must be more frequent than when disease pressure is low. Growing seed requires specific, dedicated equipment to produce a high-quality product… North Dakota statewide number: 800-732-2200, Fargo Poison Control number: 701-234-5575. After planting of stecklings, an early irrigation is done. Multiplication Once a new sugar beet variety has been developed, seed production begins. Seed delivery can be achieved successfully with either a planter drill or hand broadcasting, but the essential key to success here is delivery to a firm seedbed and at the proper depth. Sugar beets are also evaluated for resistance to mildew, resistance to curly top, beet yield, sucrose content, pulp nitrate, and pulp conductivity. x Do not plant corn or sorghum until soil samples analyzed for Tordon residue indicate no detectable levels present. Tin fungicides plus sugarbeet herbicides, including Roundup* may cause more sugarbeet leaf burn than the tin fungicides alone. Among their concerns is that GMO sugarbeets could harm the organic seed industry by contaminating chard and table beet seed production. In 1747, Andreas Marggraf isolated sugar from beetroots and found them at concentrations of 1.3–1.6%. Michigan's Saginaw Valley and Thumb area, along with the southeast corner of the state, produces more than 90% of the sugar beets grown east of the Mississippi River. 9. Fields should be checked frequently during early spring for wilting or dead plants because early detection of injury is essential to good control. Singulators should be adjusted properly to the percentage of the hole showing and lubricated to work very freely. All three crops are the same species, and therefore sexually compatible. Spraying a field but leaving the headland and a strip (or strips) in the middle untreated may be preferable, thereby allowing pre-pile harvest in untreated areas. Call the nearest poison control center for recommended treatments for any type of pesticide poisoning. Applications may be repeated as necessary during peak cutworm feeding. 11. To maximize performance, apply it: • Directly in-furrow at planting using conventional nozzles (not microtubes), • At full rate of 4 oz. Examples include Asana XL, carbaryl (Sevin XLR Plus and several generic products), Lannate LV and Lannate SP. See the inside back cover of this publication for poison control center telephone numbers. Identify glyphosate-resistant biotypes early (few plants/field) and remove surviving plants from field by hand-pulling. • Fly activity refers to fly numbers in current-year beet fields. Wind is a perennial challenge to making effective insecticide applications in the Red River Valley. Observation of posted sticky stake capture data can aid in this determination; however, it is no substitute for actual monitoring of individual fields. Begin checking for Cercospora in late June or early July after row closure, making sure to check near last year’s fields or shelter belts. Alternaria leaf spot is reported in some fields in our growing region that are favored by relatively cool temperatures and high humidity. Release tension on press wheel springs. Stecklings are harvested and placed in bags to move to the final fields for commercial seed production. Commonly, as much as 30% of the granules can be blown sufficiently far from the furrow to render them ineffective for protecting roots from insect pest injury. Glyphosate products are formulated in many different acid-equivalent concentrations. This region typically accounts for about one-eighth of national planted area. 5. The rainfall effect also can vary depending on rainfall amount and intensity. All three crops are the same species, and therefore sexually compatible. Planting the Beets. The female plant (right side) has monogerm flowers (produce one germ per seed) which will produce only one plant per seed when planted by the grower. Value of Seed Treatments. Thiophanate methyl can be used in a tank mix (with TPTH, triazole or demethylation inhibitor [DMI] fungicides, or multisite fungicides) but only once in a season. This is especially important for lambsquarters control. N/A when sampling to 4-foot and 2-foot soil depth, respectively. However, the 20- or 30-gram rate may be inadequate for medium disease pressure when the soil is warm after a heavy rainfall or when these conditions are prolonged within three weeks after planting. 7. 4. 7. Have pesticide label information available when calling. Increasing spray volume and offsetting (perpendicular to first application is ideal) subsequent applications can decrease the inactivation of glyphosate caused by dust. Before installing new plates, clean out obstructions by hand with a 1/16 inch drill bit. 9. Darksided and redbacked cutworms are the most common cutworm pests of sugarbeets in the Red River Valley. Production of high-quality sugar is especially important to growers who are paid based on extractable sugar delivered to the factories. Treatment with Counter 20G or Lorsban 15G (and most generic chlorpyrifos-containing granular materials) is limited to one application per year. Sugarbeet size at peak fly activity - Early planted beets may have sufficient root development and size to withstand some maggot feeding without major yield loss. • 65 lb./acre of nitrogen is required in the 0- to 2-foot soil depth to maximize early season crop growth, yield and quality. 3. Annual grass and broadleaves: 1 to 2 inches, B. Perennial grass and broadleaf weeds: early bud/boot stage to early flowering or in the fall at a minimum-sized plant, C. Biennial weed species: fall, after a light frost. The majority of commercial seed is produced through the transplant method where seed, supplied by member seed companies, is planted in beds for four months to produce stecks (small beets). The disease is favored by high soil temperatures. FirstRate = 30-month rotation + successful field bioassay. (The slightly lighter green 4 rows of plants in the center of the photo is one pollinator strip. After aerial application, ensure that areas around power lines and trees are side-dressed by the use of ground equipment. Run units with all seals in place. In high-risk situations, select approved varieties that are less susceptible than the average. Calibrate starter and/or fungicide application systems. Manage herbicide-resistant wild oat biotypes with Far-Go (PPI) and/or Select* or Select Max* POST at full rates to small wild oats and repeat application as necessary at approximately 14- to 21-day intervals. When unfolding, check to see that all tubes have refilled with seed. Use shims to obtain the proper air gap between the plant and meter. It is wind-pollinated and pollen can travel up to 20 km. By mid June plants have reached full height (4 to 5 feet) with flowers starting to open. This is fairly simple because application rates on granular insecticide labels and in Extension materials are listed in ounces of product per 1,000 row feet. This suggests that SBRM infestations in 2020 generally will be higher than in previous years. The following insecticides should protect sugarbeets from wireworm injury. In the Western United States, where seed production of sugar beets, swiss chard and table beets are all produced, cross-pollination is a concern. 3. Soil moisture - Good soil moisture enhances the effectiveness of planting-time granular insecticides. **Use the Olsen P test on soils with pH greater than 7. Benzimidazole-resistant isolates grow normally in the laboratory in the presence of 5 parts per million (ppm) of benzimidazole fungicide. WCBS grows sugarbeet hybrid seed and parental stocks. Postemergence granules work best under moist soil conditions, and liquids work better than granules in dry soils. Maximize weed control in conventional sugarbeets by scouting fields and applying herbicide treatments when weeds are at the cotyledon to first true leaf stage. C. beticola also has developed reduced sensitivity to triazole (DMI) fungicides. Mild winters, low disease pressure and dry harvest weather makes the area desirable for growing seed. The interval between glyphosate applications should be approximately 14 days, depending on growing conditions, and weed size and density. Tolerance to feeding injury can be enhanced with rainfall in early June and through July. Swathing of the plants is done with equipment outfitted with both horizontal and vertical cutting bars to minimize dragging of plants which could result in additional seed shattering and loss. Consider excluding NIS or HSMOC from insecticide containing tank mixes with Roundup*, especially when applied to cotyledon to two-leaf sugarbeets. Apply during conditions when plants are growing actively and avoid fluctuation in temperature. Be sure you know how effective your seed treatment is for specific problems in a field. Canada produces sugarbeets in Manitoba and Alberta. Seedex, Inc. is a member of West Coast Beet Seed Company (WCBSC), Salem, OR, a non-profit owned by the majority of the world’s beet seed companies. t Rotation to barley is: 9 months if (greater than 18 inches water + greater than 6.2 soil pH) or (moldboard plow with less than 18 inches water or less than 6.2 soil pH) or 18 months if (less than 18 inches water or soil pH less than 6.2). Threshold: No economic threshold has been established for wireworms in sugarbeets; however, field history can be a good indicator of risk. See Page 5. Sugar Beet: Beet Production The industrial demand for sugar beets is still increasing, which provides a higher price, thus incentivizing many farmers to plant more beets. If tolerant strains are present, a reduced level of control will occur. Management of Cercospora requires an integrated approach that includes early incorporation of infected debris, crop rotation, the use of varieties that are less susceptible, disease scouting, timely application of fungicide, adherence to appropriate application intervals and more frequent applications when environmental conditions are favorable for disease development. High labeled application rates should be used in areas where SBRM populations are expected to be high (see forecast map), especially in areas where SBRM problems were evident during the preceding year. Choose grid soil sampling if field history is unknown, if fertility is high, when the field has a history of manure applications, when two or more fields are merged or if phosphate levels are particularly important. 13. Thorough tillage must precede planting of sugarbeets. Adjustment and/or modification of the tickler brush will improve performance. Resistance is used to indicate that the Cercospora fungus is unaffected by a level of fungicide that previously prevented growth in the laboratory. For applications to summer annual or spring applications to perennial weed species, do not apply if the daytime low temperature is below 38 F and the daytime temperature does not exceed 45 to 50 F. 5. - Lorsban 15G and chlorpyrifos-based generics do not provide adequate protection from springtail injury. Residual herbicides applied early postemergence must be rainfall activated before waterhemp emerges in fields. Choose zone soil sampling if yield monitoring or remote imagery reveals a pattern relationship with the landscape, if no history is available or manure use has occurred, if the field has a history of relatively low phosphorus (P) rates or if mobile nutrient levels, particularly nitrate, are required. SBRM population level - Growers and crop advisers are encouraged to check individual fields for threatening fly activity levels and to monitor radio, DTN the NDSU “Crop & Pest Report” and other media sources for reports on fly activity levels from late May through June. Complete coded variety trial results for American Crystal Sugar Co. and Minn-Dak Farmers Cooperative are available in the Sugarbeet Research and Extension Reports (www.sbreb.org). Piles can be as large as 20 feet tall by 180 feet wide by several hundred feet long. 1. Seed treatment such as Kabina ST (Penthiopyrad), Vibrance (Sedaxane) or Systiva (Fluxapyroxad) will provide early season protection for about four to five weeks. 5. Springtails that damage Red River Valley beet fields are tiny (1/32 to 3/32 inch long), wingless, white to cream-colored insects with fleshy, forward-pointed antennae. A large part of industrial beet sugar production involves removing minerals and impurities from the sugar water. However, in the following discussion, they are used with specific different meanings. Co-op Agriculturists’ Office and Mobile Numbers. Cercospora leaf spot, caused by Cercospora beticola, is the most common and destructive disease in this area. 6. Remove seed plate doors. The addition of wind shields to planter row units is a practical solution that greatly diminishes the impact of wind on granule placement. The planter has no agitation in the large tank; to compensate, use pure graphite or a graphite/talc blend. In mixtures, individual fungicides should be used at least at 0.75 to 0.80 times their full labeled rates or preferably at full rates. Sowing oat cover crops immediately before beet planting can reduce SBRM injury to sugarbeet roots. Do not use this publication after Dec. 31, 2020. A composite pre-sample can be used to determine the likelihood of significant spatial variability in nitrate levels. A sugarbeet cutoff brush with metallic bristles helps remove static electricity. West Coast Beet Seed (WCBS) is jointly owned by a group of sugarbeet seed and sugar companies (American Crystal Sugar Co, Hilleshög, and SESVanderHave). Liquid formulations generally provide better control of cutworms, especially in dry soils. Because variegated cutworms feed above ground, they can be managed effectively by using foliar rescue insecticide applications. Nonregistered uses also may result in condemnation of the crop. 2. Crop rotation may reduce inoculum buildup in the soil, but this practice is unreliable because the pathogens have a wide host range and chlamydospores can survive for many years. Application Intervals: Generally, the application interval for most of the fungicides recommended is 14 days. Beet Seed Planting. Steckling beds may be covered to protect against freezing temperatures. Beets are planted from a small seed; 1lb of beet seed will plant about an acre. Infection of mature plants may not cause death, but the disease causes significant reduction in root yield and recoverable sucrose. Current populations are now also less sensitive to triazole fungicides such as tetraconazole, difenoconazole, propiconazole, fenbuconazole, prothioconazole and flutriafol. Stressed sugarbeet plants appear to be more susceptible to Alternaria, and some sugarbeet varieties are more susceptible than others. However, excessive nitrogen increases impurities and decreases sugar content. To achieve best germination, Deer Creek Seed recommends planting sugar beets at least 1/2 to 1-inch deep. Sugarbeets should be planted as early as weather, soil moisture and temperature conditions permit. The sugar beet was grown as a garden vegetable and for fodder long before it was valued for its sugar content. In-furrow applied fungicides can affect stands under cold and dry conditions, especially when used with a starter fertilizer such as 10-34-0. Some of these seed growers have been producing seed for KWS for nearly 35 years! See publication PP967 for more information on powdery mildew. The number of trade names for herbicides and herbicide combinations is increasing each year. Adjust the vacuum as necessary. His student, Franz Karl Achard, evaluated 23 varieties of mangelwurzel for sugar content and selected a local strain from Halberstadtin … This production guide will provide useful information to assist you in making timely management decisions. Nonregistered herbicide use is illegal, and a user could be subject to a heavy fine, even without detectable residue. Increase vacuum if necessary. Pesticides should not be used if they no longer are registered or have not yet received registration for sugar beet. Broadcast application is not as effective as band application under moderate to heavy disease pressure. Restriction is based on nonlegal herbicide residue that may be found in corn and sorghum and not on crop safety. Moderate application rates of labeled soil insecticides are recommended in areas where correspondingly moderate SBRM infestation levels are expected. Control may be justified for late-season infestations of three to five larvae per square foot if they are feeding near or above the soil surface. If optimal timing is in question, erring toward applying granules early is advisable. It is then run across a draper (machine with cloth belts) with additional small sticks carried up the inclined belt while the seeds roll down the belt. Commercial seed production is carried out by contracted seed growers that follow strict seed quality processes and guidelines. Having plastic residue from the production process partially block the air holes in new plates is common. Reduce dust during application by reducing travel speed because it inactivates glyphosate. Apply between 9 a.m. and 5 p.m., especially if velvetleaf, common or giant ragweed are present in the field. Sugar beets tend to behave as a perennial if flowering is not induced, thus for seed production, the induction of flowering is required. Tarnished plant bugs, commonly referred to as Lygus bugs, occasionally have caused late-season injury to Red River Valley sugarbeet fields since the late 1990s. Nonregistered pesticide is illegal and a user could be subject to a heavy fine even without detectable residue. 11. In areas with resistance/ or reduced fungicide sensitivity, it is best to use site specific fungicides (QoIs and DMIs) at full labeled rates in mixtures.
