This minimizes the amount of preemergence herbicide bound to leaf and stem surfaces and the loss of weed control this causes. Apply after small grain emergence and up to the boot stage; alfalfa should have a minimum of four trifoliolate leaves at application. The damage of dodder to the host plant varies from moderate to severe depending on the growth of the host plant and the number of haustoria attachments to the host plant. Direct seeding can also increase alfalfa vigor and population density during establishment, especially when the alfalfa seedlings are stressed, such as from droughty conditions during establishment. 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. All rights reserved. Herbicide use is most effective when weeds are young and actively growing. We conducted extensive research to explore using grass-active herbicides to remove oat companion crops in the 1990s in Minnesota. To encourage the continued growth in the production of alfalfa in Brazil, it is important to identify herbicides that act on grasses and broadleaved species and are selective to alfalfa. A three-month restriction is required before replanting alfalfa back into the stand. Management. Add AMS at 8.5 to 17 lb/100 gallons of spray solution. Apply 1 to 1.5 pints per acre preplant incorporated (PPI) to direct-seed alfalfa. Interseeded oat or suppression in oat-mulch systems is not mentioned on the Raptor label, but control of volunteer oat up to 3 inches in height or less is labeled. Higher seeding rates than 1.5 bushels per acre can increase the protective mulch cover and compete more effectively with weeds in severe conditions. For example, if … It may be impregnated or applied in liquid fertilizer. This relatively early application may require a second application to control weeds that may emerge after Roundup application, but before crop canopy closure. Summary: 2007 Herbicide Trial in Alfalfa Seed • Asulox – good alfalfa tolerance with 3 or 6 pt/A, ~80% control of mayweed. Organo-silicon surfactants can be used instead of nonionic surfactants.

Pursuit® should be applied for seedling alfalfa at the 2nd trifoliate stage and when there is less than 3” of growth in established alfalfa. Do not add any wetting agents or detergents unless directed on the label. This reduces the chance that a second application will be needed to control a new flush of weeds, while minimizing the issue created with removing larger, susceptible plants. Shark/Aim (carfentrazone, Group 14) – This post-emergence herbicide can be applied when alfalfa is dormant or between cuttings. Crop oil concentrate (COC) can be used at the rate of 1.25 percent volume/volume volume/volume (v/v), or methylated seed oils (MSO) at 1 percent v/v. Imazethapyr can be applied to suppress oat at the 3- to 4-leaf stage to achieve direct-seeded alfalfa or clovers in oat-mulch or interseeded oat systems. This gives them a head start in the spring, when they begin growing quickly as temperatures warm. Ensure good alfalfa canopy spray penetration and grass coverage.

Select/Arrow 2 EC applied postemergence will control annual grasses in seedling alfalfa, birdsfoot trefoil or sainfoin grown for forage or seed. Do not apply the tank mixture with 2,4-DB when underseeded to small grains (2,4-DB is not cleared for application to small grains). If severe competition occurs, no herbicide can selectively remove the annual grasses and not severely injure, or completely kill the forage grass seedlings. Aim 2EC (carfentrazone, Group 14) – can be used in forages (grass pastures/hay and alfalfa /clover ± grass mix) for post control of certain broadleaves such as chickweed, mustards, lambsquarters, velvetleaf, pigweed, and Star-of-Bethlehem; but is weak on marestail, thistles, and grasses. Sedges and broadleaf weeds will not be controlled. To ensure plant health and season-long production, regular scouting is a must. On this webpage, we summarize herbicides labeled to establish alfalfa. We called this an “oat mulch” system, in which companion crops could be used to protect alfalfa seedlings from wind- and water-driven soil erosion and reduce weed encroachment during alfalfa establishment. Plus, it will suppress some perennial weeds. Using oat mulch systems make it possible to establish alfalfa with an oat companion crop in areas where erosion potential is a concern, while removing oat competition before long-term stand or vigor damage to alfalfa occurs. It controls many annual grass and most broadleaf weeds in direct-seeded or oat-mulch systems. Chlorpyrifos plus gamma-cyhalothrin* (Cobalt) The signal word on the label is DANGER. Because it’s a contact herbicide, weeds must have adequate remaining foliage to be controlled. This presentation will focus on tolerance of alfalfa to flumioxazin (Chateau) and several other promising herbicides, carfentrazone (Aim) and asulam (Asulox), that may be registered in the near future for … Alfalfa Seed Following are options for crop specific AgPro programs. The degree of weed control and duration of effect vary with the following: Organic matter content of soil-Soils with high organic matter require higher application rates than soils with low organic matter for equivalent herbicide performance.
