Paraquat updates: Anyone handling and using products containing paraquat (i.e. Table 1 below compares the two systems. This practice will be very effective for controlling the weeds emerged at the time of tillage, but some farm operations may not be set up for the extra equipment, labor, and fuel needed to do this on a widespread basis. If summer annual grass weeds have emerged, add paraquat or a pint/A of glyphosate to the mixture. Herbicide mixtures and application parameters will become even more important when dealing with shortages of our most popular herbicides. We have always observed better activity out of paraquat by adding a triazine herbicide to it and by simply adding paraquat and 2,4-D to a premix that has metribuzin in it, you have a ready-made, broadspectrum burndown and residual herbicide. Tendovo 4.14ZC (s-metolachlor [Dual Mag.] In addition, we have observed that the addition of saflufenacil (Sharpen, others), can help speed the activity of glyphosate on some annual grass species. We are hearing that glyphosate prices will be in excess of $80/gallon. Kyberherbicide contains three active ingredients. + metribuzin + cloransulam [FirstRate]; groups 15, 5, 2; Syngenta) will primarily be used as a burndown product which will have some residual. Add atrazine (1 to 1.5 lb ai/A) and possibly a group 15 herbicide to boost residual broadleaf and grass weed control.
Target using regular rates of glyphosate to stretch supply. To learn more about Kyber herbicide, visitKyberHerbicide.comonCorteva.us, or reach out to your local Corteva Agriscience representative. Its burndown activity is best when applied to young (generally less than 5 in. Titan offers a full line of wheels, tires and undercarriage products for a wide variety of off-the-road equipment. Table 1. In the next section of this article, we will outline some weed control considerations based on the type of tillage system you are in and the weeds to be controlled at different times of the year. Gowan has acquired the rights to the active ingredients prosulfuron and primisulfuron from Syngenta. Example 1. LEARN HOW TO SLOW THE SPREAD OF THE INVASIVE SPOTTED LANTERNFLY. in your fields. The EPA required video training is available on the paraquat training website (users must create an account with username and password). But keep in mind, these estimates can vary between states and local areas. In addition to the training, EPA requires that paraquat products be contained in a closed system. Add saflufenacil (not needed with Verdict since it contains saflufenacil), 2,4-D or dicamba to each of them for additional foliar activity on broadleaf weeds.
Composed by Larry G. Heatherly, Oct. 2020,larryheatherly@bellsouth.net, 2022 Mississippi Soybean Promotion Board. Figure 1. The new replacement products will be Acuron XR, Acuron Flexi XR, and Acuron GT. Therefore, they should be considered a part of the arsenal of herbicides that is available to control targeted weeds, especially those such as Palmer amaranth that are troublesome in Midsouth soybean production systems. Example 5. Zidua) active ingredients. Kyberherbicide delivers 4-6 weeks of residual weed control, and may exceed 6 weeks in the right conditions. Weed control benefits from high biomass cover crops can also be realized for the 2022 growing season as well. Discover 2-days of cutting-edge ideas, techniques and strategies in Coralville, Iowa., July 28-29. Kyber herbicide is a premium solution in the fight against resistant weeds. Reviton(from Helm) is a PPO-inhibitor herbicide with the active ingredientTiafenacil(Group 14) that is intended for preplant burndown use in soybean. Flumioxazin is a group 14. Keep in mind other herbicides will need to be included to broaden the weed control spectrum. Terms and conditions apply. Its active ingredients are the same as those in Fierce MTZ, but the concentrations of each may be different between products. Voraxor (BASF) will be a premix of saflufenacil (Sharpen) + trifludimoxazin (Tirexor) [group 14] for burndown and residual. Broadleafscutleaf evening primrose, hemp sesbania, henbit, marestail, Palmer amaranth and 5 other pigweed species, prickly sida or teaweed, and smallflower morningglory. The typical use rates are 20 to 36 fl oz/A. (Photo Credit: Fred Whitford), Fall Applied Herbicides for Winter Annuals on No-Till Ground. The interval for 2,4-D will be shorter for these soybean traits.
Some of these are starting to be marketed in our region so check with one of these dealers for availability. INDIANAPOLIS Corteva Agriscience announces the launch of Kyberherbicide for the 2021 season. If you planted Enlist beans, you would use the same strategy, but no preplant interval is required if you use the 2,4-D choline (Enlist One) product from Corteva. Its registration is expected sometime in 2022. Typical use rates are 21 to 28 fl oz/A.
For growers planting Enlist E3soybeans, Kyber herbicide will fit very well in their weed management plans. We know many growers wont use glufosinate in corn since it isnt always clear what hybrids are Liberty Link and they want to save the glufosinate for soybeans. Interest rates and fees will vary depending on your individual situation. Enlist One herbicide is the only 2,4-D product authorized for use in Enlist crops. Looking for similar or complementary products? Identify glyphosate or glufosinate premixes that may be in greater supply or at lower relative costs compared to solo glyphosate and glufosinate products. As you search for alternatives to these two herbicides you may have already determined that weed control guides produced by University Extension and Industry will become your most important tool for planning your herbicide purchases for many years to come. This premix combines three modes of action, each effective individually, to control resistant weeds. Get full access NOW to the most comprehensive, powerful and easy-to-use online resource for no-tillage practices. It is very similar to Armezon or Impact. Regardless of the cause, it is also important to consider herbicide costs. The second choice would be to use clethodim for grasses + other herbicides to control broadleaf weeds.
MSO or COC plus AMS must be added to the spray solution. Adding a group #15 residual herbicide (metolachlor, dimethenamid, pyroxasulfone, acetochlor) to the postemergence application will be the backbone of your small seeded broadleaf and grass control program, and reduce the need for a second postemergence application later in the growing season. Kyber is rainfast one hour after application. Glufosinate demand, on the other hand, will not be impacted as much by choice of tillage system since we dont use glufosinate in our fall or spring burndown application, and not much is used in corn. PowerMax3 at 19 fl oz = 22 fl oz of PowerMax (0.75 lb ae/A). Product Manager, Soybean Herbicides, Corteva Agriscience.
You can also use Revulin Q, Realm Q, Armezon, Armezon PRO, Impact or Laudis for postemergence grass control if glyphosate or glufosinate is not available. As mentioned above, we will want to build the weed control program around a broadspectrum residual herbicide, so simply adding 2,4-D to premixes that contain saflufenacil (Verdict, Zidua Pro) or metribuzin (Authority MTZ, Canopy Blend, Intimidator, Kyber, Matador, Boundary/Moccasin MTZ, Trivence, or Panther Pro) makes the most sense and would require a 7 to 30 day preplant interval depending on the 2,4-D formulation and rate used. The Andersons grows enduring relationships through extraordinary service, a deep knowledge of the market, and a knack for finding new ways to add value as we have done for nearly 70 years.

Kyber herbicide is the comprehensive solution to difficult-to-control weeds in soybean fields. Reviton 2.83SC (tiafenacil (aka Tergeo); group 14; Helm) can be used in a burndown program before field corn, soybean, or wheat. Consult the weed response table such as these to choose the best product for each specific field. Sencor), flumioxazin (Group 14e.g. And waterhemp.). West Lafayette, IN 47907, An equal access/equal opportunity university. Fierce MTZ (Valent) contains the same ingredients and ratios. Secondly, regardless of tillage system, you want to build a solid residual program as the backbone of your weed control strategy to reduce reliance on using glyphosate postemergence in the crops. Current formulations of Acuron and Acuron Flexi will be phased out after 2022. We are simply pointing out which products, based on the active ingredients they contain, would be a good fit with the weed pressure we have mentioned. The new crop protection product is a preemergence soybean herbicide with three effective modes of action, including a Group 15 active ingredient. Kyber herbicide is new premium preemergence soybean herbicide available for soybean farmers beginning in the 2021 growing season. Below are some newer product premixes, revised formulations of existing active ingredients, and tradenames to consider: Syngenta is modifying Acuron, Acuron Flexi, and Halex GT.

The acquisition includes product registrations and trademarks for Peak, Spirit, Beacon, and Northstar herbicides and related intellectual property and labels. This preemergence soybean herbicide boasts three effective modes of action, including a group 15 active ingredient, to create a new level of clean. There will likely be limited supplies of other pesticide active ingredients as well, but in the short term, a shortage of these two active ingredients poses some major challenges for corn and soybean production.
It has a low use rate (1 to 3 fl oz/A) and can be tankmixed with other herbicides. The center, one of ten in Tennesee, shares a significant anniversary in the annals of No-Till history. Each mode of action in Kyber herbicide controls resistant weeds individually, and combined together, they provide a comprehensive solution. Comparison of selected application factors and herbicides in Xtend/XtendFlex and Enlist E3 soybean. The cover crops that will need to be terminated prior to corn. This premix combines a perfect addition to a program approach to weed control that also includes a burndown and postemergence herbicide. Resicore XL (Corteva) is a reformulation of Resicore for better handling, mixing, and crop safety when applied post. Rimsulfuron can be used 30 days or more before planting soybean and may help with winter annual grasses, providing some residual control of summer annual grasses as well. If you are not a cover crop user and you use fall applied herbicides for winter annuals, consider taking out glyphosate and just using 2,4-D + dicamba mixtures this fall IF you only have broadleaf weeds [chickweed, henbit/deadnettle, shepherds purse, field pennycress, mustard species, cressleaf groundsel, dandelion (which is a perennial), poison hemlock (a biennial), etc.] Terms and conditions apply. So, even if there is not a shortage, you should plan your weed control strategies for the next growing season to accommodate a limited availability because of supply or price of these two active ingredients. Pyroxasulfone is group 15. There are several different factors which are impacting this issue. For weeds that break through the residual treatment, use a postemergence treatment of glufosinate + dicamba or glyphosate + dicamba and add a 1/3 to label rate of the atrazine premix products that contains a group 15 herbicide to lengthen the window of residual weed control in the crop.
TriVolt (isoxaflutole + thiencarbazone + safener [Corvus] + flufenacet [old Define]; groups 27, 2; 15; Bayer) can be applied from PRE to V2 corn growth stage and provides residual control of many annual grasses and broadleaves at 10 20 fl oz/A. These are just a few examples of some different scenarios to consider when building a weed control program. (And common ragweed. Maverick 2.04SC (pyroxasulfone [Zidua] + mesotione + clopyralid; groups 15, 27, 4; Valent) has a wide application window from pre to 18 tall corn and provides foliar and residual control of many annual grasses and broadleaves at 14-32 fl oz/A; can be tank-mixed with atrazine and other products. According to Corteva, the product is undergoing state-by-state approvals at this time. Primary changes include increased amounts of mesotrione (Callisto) and s-metolachlor (Dual) in the new formulations of Acuron XR and Flexi XR. It is a non-selective contact herbicide that is to be used to control or suppress a broad spectrum of emerged broadleaf and grass weeds (clickherefor a list of 23 target weeds). A few newer herbicide-resistant sorghum technologies coming to the market, here is a brief overview of each. With the TruChoice Offer, you can save at the time of purchase on 100+ leading crop protection products like this one. Important Gene for Soybean Protein Content Found. oz./acre application rates, the interval between application of Reviton and planting of labeled crops or replanting after crop failures is 0 days for wheat and corn and 14 days for soybean and cotton. What if the field in Example 3 will be planted to soybean, rather than corn? The rotational interval for wheat planted after soybean is 8 months, so it should not be used if doublecropping soybean and wheat is planned.
Make sure you optimize your herbicide applications using the best methods (GPA, spray nozzles, etc. Registration is still pending but is expected sometime in 2022. By beginning a weed control program with Kyber herbicide, growers will be able to start the season clean by controlling weeds from day one, said Aaron Smith, U.S. Reviton is similar to Sharpen and is less active on marestail but has better activity on field pansy/violet, primrose, grass compared to Sharpen. All the University Extension weed control guides and most of the guides written by the crop protection industry have weed efficacy tables in them to help the user determine which products provide acceptable control of the most common weeds in the specific geographical area covered by the guide. Failure is not an option for herbicide applications.

Kyber herbicide is an excellent addition to a program approach for broad-spectrum control of resistant broadleaf and grass weeds.
JavaScript seems to be disabled in your browser. A no-till corn field with no winter annual grasses, but lots of horseweed (marestail), giant ragweed, and lambsquarters have started to emerge. As in the recent past, there are absolutely no new herbicide modes of action. Viewourprivacypolicy.
It is not to be applied by air or through any type of irrigation system. Trademarks of Corteva Agriscience and its affiliated companies. New herbicide products, label updates, and industry news about weed management are highlighted in the article. Instead of using 32 or 44 oz/acre of a Roundup brand product, consider using the standard rate on the label such as 22 oz/acre for Roundup PowerMax (Note Roundup PowerMax3 will be launched in 2022 and the standard rate is 20 oz/acre; equivalent to 22 oz/acre of the old R. PowerMax formulation). Not all applicants will qualify. Find supplemental labels for this product. Example 4. Keep in mind that if you mix reduced rates of glyphosate with 2,4-D, dicamba or both, grass control can be compromised (herbicide antagonism). Of course, these guides assume all herbicide label recommendations are followed for the application and herbicide resistance in the weed population has been considered. However, dont fall into the trap of thinking you only get one application of these herbicides so you should wait for the last weed flush before you spray. Its registration is expected by possibly early 2022. For this episode of the No-Till Farmer Influencers & Innovators podcast, brought to you by Verdesian Life Sciences, we're joined by Blake Brown, director of the AgResearch and Education Center at Milan. If you are using a clethodim or rimsulfuron product instead of paraquat, add 2,4-D or dicamba to help with broadleaf weeds. It must be applied with an adjuvant (methylated seed oil/crop oil concentrate or nonionic surfactant) for optimum burndown activity. Isoxaflutole, rimsulfuron, and thiencarbazone have foliar and residual activity on grasses and will control a few selected broadleaf weeds. Shieldex 3.33SC (tolpyralate; group 27; SummitAgro) is a newer, low use rate (1 to 1.35 fl oz/A), HPPD-herbicide that controls annual grasses and broadleaves postemergence in field and sweet corn.
