Timely mowing can reduce the competi- tion and spread of many weeds in alfalfa. For established stands (i.e., alfalfa that was planted in fall or spring and has gone through a first cutting/mowing), apply 1.1 to 4.2quarts/A prior to weed emergence. Roundup Ready Alfalfa Seed quantities limited initially. The 4-H Name and Emblem have special protections from Congress, protected by code 18 USC 707. Alfalfa autotoxins do not affect any other crop Spraying no w protects alfalfa weevil parasites emerging later. Weed competition during establishment will reduce alfalfa seedling vigor and potentially reduce the alfalfa plant population, which can affect crop yield and quality throughout the life of the stand. h treat weeds in their seedling stage apply when the alfalfa has 3 to 4 trifoliate leaves apply in 50 to 60 gallons of water per acre, this is especially important when the weeds are beyond their seedling stage d. (e. don't apply when the temperature is 80°F or above f. … Either cultipacker type seeder or a grain drill can be used for a conventional tillage for planting alfalfa. Alfalfa is the most productive legume for Missouri, with potential yields exceeding six tons of hay per acre on good soils. Toxins inhibit the ability of the root radicle to elongate. Weed control. Extensive alfalfa winter injury can upset forage inventories, make dairy ration formulation difficult and result in the need to purchase hay, which can be expensive. Did any drift occur? This results in reduced seedling emergence. Proc. If weeds are stressed or have dust on their leaves In the remaining states, apply in the fall or spring to seedling alfalfa when the Site selection. Michigan State University Soil Testing Lab. Marble. Reference to commercial products or trade names does not imply endorsement by MSU Extension or bias against those not mentioned. University of Wisconsin – Madison number of alfalfa seedlings emerged on 19 Oct. and 2 Nov. 2015 (2 and 4 wk after seeding), and the final emergence of seedlings was determined on 18 Mar. How long they remain and what affect they have on a new alfalfa seeding is a function of soil type, temperature, and amount to rainfall. The problem with spraying the early seeded alfalfa now is that any germinated weeds will be shielded by the alfalfa canopy. 2,4-DB in itself is not toxic to plants but ... spray volumes are used (50-200 gallons of spray mix per acre) then additional non-ionic surfactant can improve performance. Once a stand of alfalfa is killed, whether by plowing, spraying or even winterkill, the autotoxic compounds are released into the soil environment. Proper fertilization of alfalfa Fourth, spray herbicide before planting alfalfa. Cosgrove, D.R. It is not known what the thresholds is below which autotoxicity is not a concern. To contact an expert in your area, visit https://extension.msu.edu/experts, or call 888-MSUE4MI (888-678-3464). MSU is an affirmative-action, equal-opportunity employer. if alfalfa has 6 trifoliate leaves. Include a crop oil concentrate in the spray mixture. Seeding rate. In this Focus on Forage, we will discuss what causes autotoxicity, factors that affect it, and ways to reduce the effect. Seeding into an Existing Alfalfa Stand by Wayne K. Coblentz1 and Richard E. Muck2 Alfalfa (/ æ l ˈ f æ l f ə /), also called lucerne and called Medicago sativa in binomial nomenclature, is a perennial flowering plant in the legume family Fabaceae.It is cultivated as an important forage crop in many countries around the world. Focus on Forage – Vol 5: No. Table 4. The production of chemical compounds by a plant that are toxic to members of the same species is known as autotoxicity. Plants produce a wide range of chemicals aimed at defending them from attack by insects and diseases. An exception would be large dead areas, such as from ice sheeting, or failed new seedings where only young plants (less than one year old) are present. Forage and Grassl. djunders@facstaff.wisc.edu. 2001. One of the most common problems faced by hay or silage producers is how to manage production schedules around unfavorable weather. Water-soluble compounds produced by existing alfalfa . DO NOT apply to seedling alfalfa earlier than 5 months after emergence. I … Thorough coverage is essential for best control. oz. Apply a long residual insecticide if the larval number you find is greater than the number in the table above for the average height of alfalfa sampled.

DO NOT apply to seedling alfalfa earlier than 5 months after emergence. Surviving plants will develop a secondary root system that is shallow and more highly branched than that of an unaffected plant. This condition is called “autotoxicity” and occurs most frequently when alfalfa is killed shortly before reseeding or when many live alfalfa plants remain in the stand. This is called “alfalfa autotoxicity”. Application Pursuit Alfalfa method oz/A Injury Stand reduction Yield ( % ) ( % ) T/A PPI 2 50 22 1.0 4 62 33 0.5 6 72 43 0.6 PE 2 45 18 1.2 4 60 42 0.8 6 73 48 0.8 Weedy check -- 0 0 1.6 Weed-free check -- … Wisconsin studies have shown yield reductions of 30% and 70% when alfalfa was seeded 4 weeks or 2 weeks after plowing down old alfalfa plants (1) (Fig. I have a 16 acre field in northern NV that is irrigated via flood irrigation. PP 73-76. May be applied to dormant and actively-growing alfalfa. 1999. For established stands (i.e., alfalfa that was planted in fall or spring and has gone through a first cutting/mowing), apply 1.1 to 4.2quarts/A prior to weed emergence. In erosion-prone areas, conservation plans may restrict farmers from converting winterkilled alfalfa to corn or other row cr, Effects of Rain Damage on Wilting Forages For mixed stands with grass, 15 to 16 pounds per acre is recommended. alfalfa plants or weeds can severely restrict growth of new seedlings. Oil and soap added to the baking soda ensure the spray sticks to the leaves. Plants produce these compounds to help “carve out” a space for themselves and reduce competition from other plants for water, nutrients and light. ... "My 10 year old alfalfa stand was pretty ragged so I intended to plow it up and start over. Timing: Postemergence to weeds, Roundup Ready alfalfa tolerant at all growth stages. Conf. The red pepper spray is designed to make your plants less tasty to these garden pests. if alfalfa has at least 3 trifoliate leaves and 12.8 fl oz (0.2 lb a.i.) Crop rotations also suffer when farmers switch to other crops to replace damaged alfalfa stands. For seedling alfalfa (2-trifoliate to six inches tall), apply Prowl H2O at 1.1 to 2.1 pints pt/A prior to weed emergence. Amer. They include metribuzin, Velpar, Sinbar, Pursuit, Raptor, and Karmex. Plant your wheat or forage grass seed into these pots and wait for the seedlings to germinate in order to observe any signs of herbicide carryover injury that may be present. Each harvested dry matter ton of alfalfa removes approximately 11 pounds of P2O5 and 53 pounds of K2O. Invest in a soil analysis before planting. The good news is that there are herbicides to control most weed problems in alfalfa. Plants that emerge have shal- If you need to repel mammals and birds, make a batch of red pepper spray. Plants that are healthy in fall and then winterkill will not release the toxins from the roots until they thaw. Researchers at the University of Missouri found that new seedlings planted within 8 to 16 inches of an old alfalfa plant had significant yield reductions (2). Rate: Up to 44 oz/A Roundup Original Max or WeatherMax in a single application, not to exceed a total 132 oz/A for in-crop treatments per year . The age of the existing alfalfa stand will affect autotoxicity. In all of the scenarios discussed above except rotating out of alfalfa for at least one year, some yield reduction will likely be experienced. Progressive Cattle magazine captures the essence of the cattle producer and ranching experience. Use the technology to its fullest – it has been observed how competitive even seedling weeds can be to alfalfa. plants may inhibit root growth of new alfalfa seedlings. Can I thicken an old alfalfa stand by interseeding alfalfa? Apply when alfalfa is in the first trifoliolate leaf stage. This compound is present throughout the plant but is more concentrated in top growth than roots. WILDFIRE™ per 100 gallon tank mix with contact herbicides. The cause of alfalfa autotoxicity has never been fully explained and can cause direct failure of germination and seedling establishment. Autotoxicity affects the development of the seedling root system. Old stands of alfalfa release a toxin that reduces the germination and growth of new alfalfa seedlings. Follow soil test recommendations from the Michigan State University Soil Testing Lab after your soil is analyzed. Following are the factors to consider in alfalfa planting. Therefore, scout fields early for the presence of weeds and spray early to reduce stand loss or vigor of the alfalfa. When seeding alfalfa in the spring, summer annual weeds are the biggest problem. Alfalfa is one of the major forage crops in dairy and livestock production as well as an expensive crop to establish. On sandy soils where the toxins are more available and more easily taken up, the effects are more acute but are less persistent due to leaching. If your soil pH is lower than 6.5, symbiotic nitrogen fixation may not function properly. Some examples of infestations and recommendations are as follows: If one competitive broadleaf weed or grass plant per square foot is found, spray in October or November. We teach, learn, lead and serve, connecting people with the University of Wisconsin, and engaging with them in transforming lives and communities. Pursuit may be used on established alfalfa-grass mixtures. We are also examining seeding the alfalfa, spraying with Roundup and then seeding a perennial grass into the stand to establish grass legume mixtures. Roundup Ready Alfalfa Seed quantities limited initially. 2,4-DB amine is a foliar applied systemic herbicide which is often used in seedling alfalfa to control small broadleaved weeds. In part, this is due to the very competitive environment the new seedling is placed in and in part due to autotoxic chemicals secreted by the existing plants. Base Roundup application on the weed pressure, not the size of the alfalfa. New Seeding. If you must plant a cover crop, seed oats or barley at 30-40 lbs per acre ahead of seeding alfalfa. Roundup Ready Alfalfa was first released in 2005 but was pulled from the market in 2007 until an Environmental Impact Statement (EIS) by the USDA could be completed. These compounds are called secondary metabolites, as they have no metabolic function in the plant except as a defensive mechanism. Michigan State University Extension programs and materials are open to all without regard to race, color, national origin, gender, gender identity, religion, age, height, weight, disability, political beliefs, sexual orientation, marital status, family status or veteran status. Good management and attention to some of the potential pitfalls is required to minimize the risk of establishment failure. Do not use on mixed stands. Control … Conventional tillage is a more desirable planting method for flat and uniform fields than no-till planting, which is for rocky or steep slopes. Soc. Alfalfa is a tap-rooted crop and can last five years and longer under proper management. 2 cuttings were taken off of it last year. Seedling dock can be controlled in seedling stands, but established dock in established alfalfa cannot be controlled with BUTYRAC 200. Spraying will give you more pure alfalfa but may cost some in total tonnage. DO NOT apply Solicam within 28 … Test soil before planting Proper fertility management, includ-ing an adequate liming program, is the key to optimum economic yields. There are a number of potentially autotoxic chemicals produced by alfalfa, one of which is called medicarpin. For broadcast seeding, seeding rates need to be increased by 10 to 20 percent. It is best to get these out as early as … Alfalfa autoxicity is a trait which causes alfalfa to be toxic to its own seedlings. Control is best when alfalfa is in the 3rd trifoliolate leaf stage and grass weeds are between 2 to 6 inches tall, growing vigorously before tillers develop. Over time, some farmers have learned planting alfalfa in the fall instead of the spring can make a significant difference in alfalfa yield and development the following year. We are also examining seeding the alfalfa, spraying with Roundup and then seeding a perennial grass into the stand to establish grass legume mixtures. L L L L L Plant height 2" 4" 6" 8" ! Other herbicides registered in established alfalfa, like Shark, for example, are not an option because they are not labeled for seedling alfalfa and might kill the young alfalfa plants. The cause of alfalfa autotoxicity has never been fully explained and can cause direct failure of germination and seedling establishment. Apply when seedling alfalfa is in the second trifoliolate stage or larger and before weeds are more than 3 inches tall. Remove the competition of the companion crop as soon as possible. Planting a crop such as oats, sorghum or other early harvested crop may help in that some of the toxin may be removed through plant uptake. They all control mustards and pennycress, but Karmex and Pursuit do not control downy brome very well. This is the best and safest way to manage new seedings of alfalfa. Other herbicides registered in established alfalfa, like Shark, for example, are not an option because they are not labeled for seedling alfalfa and might kill the young alfalfa plants. On heavier textured soils, the toxins are more tightly adsorbed to soils colloids and less prone to leaching. This process is known as autotoxicity. Did any drift occur? Studies at River Falls showed stands densities as low as 30 stems/ft2 exhibited autotoxicity similar to stands with 70 plants/ft2. 2US Dairy Forage Research Center, Madison, WI Am. Progressive Cattle magazine captures the essence of the cattle producer and ranching experience. It is a water soluble compound that leaches readily into the soil from both decomposing plant material and growing plants. In the case of a spring-kill followed by spring replant, serious yield reductions are possible. On established alfalfa stands weeds seldom cause stand thinning but rather fill holes were alfalfa has died out. Pre-plant. To maximize the benefits of Roundup Ready alfalfa, glyphosate should be applied to seedling alfalfa at the 3 to 5 trifoliate stage when weeds are less than 4 inches tall. Alfalfa seedlings establish slowly and are very sensitive to competition for limited resources. Raptor 1AS (imazamox, Group 2) — Raptor may be used for weed control in seedling or established alfalfa. The reduced rate seedling year application is specifically First, spray the growing grass sod with a non-selective herbicide. Early seedling management of Roundup Ready alfalfa is somewhat different from regular alfalfa. Timing of seeding for new alfalfa establishment is critical to the success of the emerging crop and for the future success of the stand. In AA Hanson, DK Barnes and RR Hill, Jr., Alfalfa and Alfalfa Improvement, 303-22. 2016. Even if thawing takes place during a winter warm up, little leaching or microbial degradation of these compounds will take place until spring. Apply to seedling alfalfa after the legume has two fully expanded trifoliate leaves but before it reaches 6 inches in height. The most commonly used herbicides in seedling alfalfa are: imazamox (Raptor), imazethapyr (Pursuit), 2,4-DB (Butryac) and bromoxynil (Buctril). The most common weed control practices for alfalfa are with mechanical and chemical means. Alfalfa does well on well-drained soil rather than wet, heavy clay soils and requires good soil pH ranging from 6.5 to 7.0. This gives the toxins time to be degraded, leached, or otherwise removed from the soil environment. 4 Proc. Among these chemicals are some that inhibit the growth of other plant species. These compounds are microbially degraded and so conditions that favor microbial growth (warm, moist versus cool, dry soils) reduce the persistence of the toxins. Alfalfa is a plant species that exhibits autotoxicity. It has a new stand of RR alfalfa that was planted last spring. If you don't have that commitment, don't plant alfalfa. While summer seeding can work well on lighter soils, it can present a higher risk of heaving on heavier soils. For seedling alfalfa, Prowl H2O can be applied at 1–2 pt per acre once alfalfa has reached the second trifoliate stage of development but prior to reaching 6 inches in growth. If the field has a history of a dock problem, spraying in the fall after fall planting of alfalfa is suggested. Crops Labeled for Use Alfalfa Stage of Crop Growth Active Alfalfa Alfalfa-Grass Mixtures Clovers (Red, Aslike, Ladino) Birdsfoot Trefoil Lespedeza Dormant Semi-Dormant Non-Dormant Between Cuttings Spot Spray or Wiper Application Ingredient Products Before Seeding glyphosate Roundup, etc. Apply 16 fl. So, spraying the fall-planted seedlings now will kill up to 10% (the non-Roundup Ready alfalfa plants) and leave the field with hay containing dead stems (yes, all stems in alfalfa hay are dead anyway.) In case of emergency Call your poison control center: 1-800-222-1222 If the patient has collapsed or is not breathing: call 9-1-1 Pesticide Safety Information The degree of toxicity is directly related to the amount of time between killing the old stand and establishing the new stand. Research in this area is somewhat conflicting. COMMENTS: A systemic herbicide with no soil residual. This information is for educational purposes only. Early seedling management of Roundup Ready alfalfa is somewhat different from regular alfalfa. They include metribuzin, Velpar, Sinbar, Pursuit, Raptor, and Karmex. This article was published by Michigan State University Extension. If a grain crop is desired, plant the crop without alfalfa and then seed alfalfa into the stubble of this crop at a later date. Table 4. Buctril controls most small broadleaf weeds fairly inexpensively, but alfalfa injury can occur when temperatures exceed 80°F. First, spray the growing grass sod with a non-selective herbicide. For spring seeding, weed control is essential to prevent seeding failure from severe weed pressure. On no-till planting, only post-emergence herbicides, such as Raptor, Pursuit, or Select can be used. In early 2011, Roundup Ready Alfalfa was once again available for sale and planting. On established alfalfa stands weeds seldom cause stand thinning but rather fill holes were alfalfa has died out. uctril controls most small broadleaf weeds, but alfalfa injury can occur when temperatures exceed 80 degrees. Inevitably, some wilting forage crops are damaged by rainfall each year, and producers often inquire about the effects of rain damage, and what impact this may have on f. This form needs Javascript to display, which your browser doesn’t support. Proper fertilization of alfalfa Goal. Applications made with this product when temperatures are expected to exceed 80ºF at and 3 days following application can result in unacceptable crop injury. Apply a long residual insecticide if the larval number you find is greater than the number in the table above for the average height of alfalfa sampled. 29. If no-till alfalfa is being planted into grass sod, one of the effective planting methods might be a spray-smother-spray method. Alfalfa is a tap-rooted crop and can last five years and longer under proper management. Vancouver, BC. May be applied to dormant and actively-growing alfalfa. Plant height 2" 4" 6" 8" ! An EEO/AA employer, University of Wisconsin-Madison Division of Extension provides equal opportunities in employment and programming, including Title VI, Title IX, the Americans with Disabilities Act (ADA) and Section 504 of the Rehabilitation Act requirements. Timing of seeding for new alfalfa establishment is critical to the success of the emerging crop and for the future success of the stand.
