Bayer statement on XtendiMax herbicide

February 16, 2023

We are looking forward to a great 2023 growing season! Pre-season preparations are in full swing, and we are focused on bringing the best technologies and support to help growers succeed this year.

Many growers are choosing Roundup Ready® Xtend seeds and XtendiMax® herbicide with VaporGrip® Technology, and we appreciate the continued efforts to complete the mandatory pre-season training. More than 4,000 growers and applicators have already completed Bayer-led dicamba training for 2023, which outpaces previous seasons and shows that growers continue to prioritize this technology. Information about Bayer-led trainings is online here.

Of course, it will continue to be absolutely necessary that every grower and applicator using XtendiMax herbicide completes the mandatory training and follows the label instructions in 2023. The use of any dicamba product that is not approved and labeled for over-the-top use with Roundup Ready Xtend crops is strictly prohibited by federal and state laws.

Growers and applicators must check the online version of the label within 7 days before application in case there have been any recent state- or federal-level updates to the dicamba product labels. Just this week, the U.S. EPA approved the following updates, which we proposed for our XtendiMax herbicide:

  • For Illinois, Indiana, and Iowa, there is now a June 12 application cutoff date, and there is also now a growth stage cutoff of V4 for soybeans in these three states.
  • For South Dakota, there is now a June 20 application cutoff date.

These label updates for Illinois, Indiana, Iowa, and South Dakota also apply to Engenia® herbicide and Tavium® herbicide.

We will continue to do our part to help growers and applicators use this technology responsibly and successfully. We have refined our dicamba trainings based on learnings and feedback. We continue to offerctools and resources conveniently on RoundupReadyXtend.com, including regional weed-management recommendations and incentive programs. We also encourage customers to download the RRXtend Spray App, which gives location-specific weather forecasts, digital record keeping capabilities, and a variety of educational resources. As always, customers should not hesitate to call on their local Bayer representative if they need any additional support.

We continue to hear from growers that Roundup Ready Xtend seeds and XtendiMax herbicide are vitally important. We are very proud of the 2.9 bushel per acre yield advantage of the Roundup Ready Xtend technology over the competition in field trials over the past 4 years *, and the 94% weed-control satisfaction rating from growers since we launched XtendiMax herbicide in 2017**. We are striving for an even higher yield advantage and satisfaction rating in 2023!

We stand fully behind our Roundup Ready Xtend seeds and XtendiMax herbicide. We are indeed proud to bring these innovations to growers, and we are confident that XtendiMax herbicide, when used according to the product label instructions, can be used effectively and successfully on-target. Let’s all do our part and have a great 2023 season!

Roundup Ready Xtend Crop System Update

July 22, 2021

We take inquiries about potential off-target movement very seriously, and we encourage growers, applicators, or anyone else with questions or concerns to contact us at 1-844-RRXTEND. Those who reach out to us will be contacted within 48 hours to arrange a field visit so we can help document the situation, including the cause of any symptomology observed. The data and information that Bayer, other registrant companies, and state authorities collect will be submitted to the Environmental Protection Agency (EPA) for its independent analysis.

Now that we are past the June 30 cutoff date for soybeans, we expect to have a more comprehensive view of growers’ experiences with XtendiMax® herbicide with VaporGrip® Technology in the next few weeks. We appreciate all the efforts made by growers this year to complete the mandatory pre-season training and implement the new EPA label requirements designed to further help with effective and on-target applications. The early feedback from growers about the value of the system and the implementation of the new label changes, including use of the new volatility reducing agents, is encouraging and we look forward to having a more complete view of the season in the coming weeks.

Every season and every field is unique, and there are a range of potential contributors to the kind of symptomology being reported, which is why we believe it is important to thoroughly evaluate each case to understand the facts, including the scope and severity of observed symptomology and the potential causes. We will continue to do our part to document the season and support growers.

We stand fully behind our XtendiMax herbicide. Growers need multiple weed-control options, and XtendiMax herbicide is one important tool helping growers safely and successfully control problematic weeds. We thank growers for including XtendiMax herbicide in their integrated weed-management programs, and we will continue to support them throughout the season. We will continue to look for additional ways to support the co-existence of multiple systems and tools for growers.

Strong preparation paves way for successful 2021 season for growers
using XtendiMax® herbicide

The Roundup Ready® Xtend Crop System continues to be the leading weed-control system among U.S. soybean and cotton growers.

St. Louis, March 2, 2021

This season, with the new 5-year registration for XtendiMax® herbicide with VaporGrip® Technology and the introduction of XtendFlex® soybeans, U.S. growers using the Roundup Ready® Xtend Crop System have more options, flexibility, and support than ever before to help them have a successful 2021.

“Helping growers protect their crops and have successful harvests is what we do,” said Alex Zenteno, dicamba product manager. “We are excited to bring U.S. soybean and cotton growers these tools in 2021, and we will continue to support our customers to help with proper stewardship so they can achieve great weed control and strong harvests.”

Bayer is offering a variety of free training options – including live webinars every Wednesday at 9 a.m. Central through the end of March 2021, self-guided online modules, and limited in-person workshops for customers unable to connect online – so that applicators can safely and effectively prepare for the season. We will continue offering training up until the application cutoff dates this summer. Applicators can sign up for training at RoundupReadyXtend.com/Training. XtendiMax herbicide remains a restricted use pesticide (RUP) and all certified applicators must undergo annual training to use the technology.

“Our convenient online training options, not surprisingly, have been really popular this year,” said Mark Groth, dicamba product stewardship lead. “The webinars allow trainees to ask questions and interact real-time with Bayer weed scientists. We are also providing customer technical support through our 1-844- RRXTEND line to assist with a seamless virtual experience. The participation and feedback have been very positive, and all indications are that applicators are poised to have a successful season with the new XtendiMax herbicide label.”

The new EPA-approved product label for XtendiMax herbicide includes the following:

  • Requirement that an approved volatility reduction adjuvant (VRA) be tank mixed with XtendiMax herbicide for all applications to further control volatility.
  • Requirement of a downwind buffer of 240 feet, and 310 feet in areas where listed species are located.
  • Prohibition of OTT application on soybeans after June 30 and cotton after July 30.
  • Simplification of the label and use directions so growers can more easily determine when and how to properly apply.

The Bayer-led trainings explain the new label requirements in a clear and easy-to-understand way. Bayer has also updated the XtendiMaxApplicationRequirements.com webpage, which details the application requirements, including the approved tank mix products, volatility reduction adjuvants (VRAs), nozzles, and drift reduction technologies. Even more resources are available at RoundupReadyXtend.com to supplement the trainings and further help ensure growers and applicators understand and can successfully use the technology.

Regarding VRAs, Bayer has enabled the launch of VaporGrip® Xtra Agent products that deliver additional VaporGrip® Technology to spray tanks for further reduction of potential dicamba volatility. Click here for a VaporGrip® Xtra Agent one-pager that details the extensive testing behind this VRA that has been conducted by both Bayer and U.S. academic weed scientists. A list of approved VRAs is available here: XtendiMaxApplicationRequirements.com/#/VRAlist.

“The Roundup Ready Xtend Crop System gives growers the best opportunity to maximize yield potential,” said Megan McQuoid, soybean trait marketing manager. “It controls more weeds than any other soybean system.1 When it comes to yields, harvest results from 2020 confirm that Roundup Ready 2 Xtend® Soybeans, as part of the Roundup Ready Xtend Crop System, has an average 3.5 bushel per acre yield advantage and a 78% win rate over the competition in farmer-managed trials.2 And 2020 trials of the new top volume XtendFlex soybeans show an average 4 bushel per acre yield advantage and a 70% win rate over the competition in germplasm trials."3 More details available at RoundupReadyXtend.com/YieldResults.

To further help growers be successful in 2021, Bayer is offering the Bayer Plus Rewards program and an enhanced Spray Early with Confidence program. Bayer Plus Rewards will give qualifying growers using XtendiMax herbicide the opportunity to earn rewards and cash back. Spray Early with Confidence is designed to help growers create effective weed-management programs and provide growers a weed-control guarantee of up to $15/acre when the programs are followed. The 2021 Spray Early with Confidence program has been enhanced to provide more choice and to offer a 21-day broadleaf weed-control guarantee for growers using XtendiMax herbicide together with a pre-residual with two active ingredients.

During the 2021 season, Bayer is committed to staying connected with growers and keeping them informed about any new resources, programs, and other developments related to the Roundup Ready Xtend Crop System. The RoundupReadyXtend.com website will continue to serve as a central resource for the latest updates and materials, and the 1-844-RRXTEND call center is again open to growers, applicators, and others who have questions or inquiries about applications, potential off-target movement, or weed management. Those who reach out to Bayer through the 1-844-RRXTEND call center will be contacted within 48 hours to arrange a field visit.

The U.S. EPA announces new 5-year registration for XtendiMax® herbicide, Bayer’s low-volatility dicamba product

The new registration follows launch announcement for XtendFlex® soybeans and enables full potential of industry-leading Roundup Ready® Xtend Crop System

St. Louis, October 27, 2020

Today, the U.S. Environmental Protection Agency (EPA) announced a new 5-year registration for XtendiMax® herbicide with VaporGrip® Technology, an important weed-control tool for many U.S. growers. The EPA stated that “With today’s decision, farmers now have the certainty they need to make plans for their 2021 growing season. After reviewing substantial amounts of new information, conducting scientific assessments based on the best available science, and carefully considering input from stakeholders we have reached a resolution that is good for our farmers and our environment."

“We welcome the EPA’s science-based review and registration decision providing growers access to this important tool,” said Lisa Safarian, President of Bayer Crop Science North America. “Growers need options, and we are proud of our role in bringing innovations like XtendiMax herbicide forward to help growers safely and successfully protect their crops from tough-to-control weeds.”

The new EPA-approved product label for XtendiMax herbicide includes some changes to further ensure growers can use the product successfully. The EPA stated, “To manage off-site movement of dicamba, EPA’s 2020 registration features important control measures, including:

  • Requiring an approved [volatility reduction] buffering agent (also called a Volatility Reduction Agent or VRA) be tank mixed with OTT dicamba products prior to all applications to control volatility.
  • Requiring a downwind buffer of 240 feet and 310 feet in areas where listed species are located.
  • Prohibiting OTT application of dicamba on soybeans after June 30 and cotton after July 30.
  • Simplifying the label and use directions so that growers can more easily determine when and how to properly apply dicamba.”

“Growers have been clear how vitally important this tool is for their weed-management programs,” said Alex Zenteno, Bayer dicamba product manager. “The EPA’s strong science-based decision and new measures, including the introduction of VaporGrip® Xtra Agent, will help growers use the product even more successfully. We look forward to working with growers to ensure they are aware of the new XtendiMax herbicide label and prepared for the upcoming season. We take our stewardship responsibility very seriously, and we will continue to enhance our trainings, resources, and other support heading into 2021.”

The new EPA registration for XtendiMax herbicide follows Bayer’s recent launch announcement for XtendFlex® soybeans, which brings additional yield potential and weed-control flexibility to the Roundup Ready® Xtend Crop System.

“Now that growers have certainty about the registration of XtendiMax herbicide and availability of XtendFlex soybeans, we are excited for our customers to have an outstanding 2021 season and beyond,” said Safarian. “We are committed to the Roundup Ready Xtend Crop System, which will continue to evolve and play an important role in Bayer’s crop protection and seed portfolio going forward.”

The Roundup Ready® Xtend Crop System Yield Advantage

“The 2020 season was unique in many aspects, but the yield advantage seen by farmers using the Roundup Ready Xtend Crop System proved to be consistently high once again,” said John Chambers, Bayer’s North American Head of Market Development. “Harvest results so far show that the Roundup Ready Xtend Crop System has an average 3.5 bushel per acre yield advantage1 over the Enlist™ Weed Control System in farmer managed herbicide systems trials. We’ve seen consistent performance with a 75% win rate across these comparisons. Overall, farmers continue to experience excellent weed control with higher profit potential. We encourage our customers to connect with their local seed seller to understand local performance and product recommendations.”

“In the early results from Bayer’s commercial germplasm trials, farmers continue to experience high-yield performance and the solid agronomics they have come to expect,” added Chambers. “When we look at the performance of Bayer’s top volume XtendFlex® soybean products, they have won over 70% of the comparisons against Enlist E3™ soybeans so far and are delivering a 4+ bushel per acre advantage.2

“In addition, cotton with XtendFlex® Technology continues to see strong yield potential and agronomic results from what has been harvested thus far,” added Chambers. “Bayer looks forward to sharing the yield results shortly after harvest. From 2017-2019, Bollgard® 3 XtendFlex® cotton saw an 87 lbs. per acre advantage vs. key competitors in head-to-head testing.3

Frequently Asked Questions​

Do you remain confident in the Roundup Ready Xtend® Crop System?

Absolutely. Bayer stands fully behind our Roundup Ready Xtend Crop System, including the seeds, traits, and XtendiMax herbicide. We are proud of our role in bringing innovations like these forward to help growers safely and successfully grow healthy crops.

The new EPA registration for XtendiMax herbicide follows Bayer’s recent launch announcement for XtendFlex® soybeans, which brings additional yield potential and weed-control flexibility to the Roundup Ready Xtend Crop System. Now that growers have certainty about the registration of XtendiMax herbicide and availability of XtendFlex soybeans, we are excited for our customers to have an outstanding 2021 season and beyond. We are committed to the Roundup Ready Xtend Crop System, which will continue to evolve and play an important role in Bayer’s crop protection and seed portfolio going forward.

Where can growers find more information on the new XtendiMax herbicide label and application requirements?

Growers can find application requirements at xtendimaxapplicationrequirements.com. Additional resources will be added to our webpage before the 2021 spray season.

Where can I find state approval information?

We will keep RoundupReadyXtend.com updated with the latest state approval information.

What crops can XtendiMax herbicide be applied to?

XtendiMax herbicide and other low volatility dicamba formulations can be applied over the top of dicamba tolerant cotton and soybeans within the Roundup Ready Xtend Crop System. These traits include:

  • XtendFlex® soybeans
  • Roundup Ready 2 Xtend® soybeans
  • Cotton with XtendFlex® Technology

Why are there increased downwind buffers on this new label? Was the shorter downwind buffer on the previous label not protective enough?

The new product label includes additional measures, including increased downwind buffers, to further reduce the potential for off-target movement and further strengthen the product registration. It is important to emphasize that if a user determines that adjacent sensitive crops and/or certain plants are downwind the label requires that the user DO NOT SPRAY this product.

Why do Endangered Species Act (ESA) counties have an increased downwind buffer requirement (compared to non-ESA counties) and an additional requirement of an omnidirectional buffer?

In ESA counties, a 310-foot in-field wind-directional spray-drift buffer, and a 57-foot omnidirectional in- field buffer is required to protect federally listed threatened and endangered species. The increased downwind buffer provides an added level of protection for endangered and threatened species in EPA's assessment.

Why is the application window determined by a calendar cut-off date (instead of a number of days after planting or plant stage)?

The new product label includes additional measures to further strengthen the product registration, including a more simplified label for increased ease of use. Calendar cut-off dates are easy to follow and provide a clear definition on when the product can no longer be used.

What resources (aside from the XtendiMax herbicide label), will be available to better understand the new label requirements?

We look forward to working with growers to ensure they are aware of the new XtendiMax herbicide label and prepared for the upcoming season. Importantly, mandatory applicator training and record keeping remain important requirements with the new XtendiMax product label. We take our stewardship responsibility very seriously, and we will continue to enhance our trainings, resources, and other support heading into 2021.

Resources will include the following:

Dicamba-based training required for all users will also be available starting in early January. More details about our training and stewardship efforts are available here.

Why is VaporGrip® Xtra Agent required in the application of XtendiMax herbicide? Is the XtendiMax herbicide with VaporGrip Technology formulation not effective at reducing potential dicamba volatility?

We are always looking to evolve and further enhance all our products to help our customers maximize success.

We stand fully behind our low-volatility XtendiMax herbicide with VaporGrip Technology formulation. For the last four seasons, the vast majority of growers have reported successful on-target applications when following the label. Still, we support any enhancements that further improve our already low-volatility XtendiMax herbicide formulation. VaporGrip Xtra Agent provides an increased reduction of dicamba volatility potential when added to the tank and we believe this will bring additional comfort and success to growers and applicators.

What is VaporGrip® Xtra Agent?

VaporGrip® Xtra Agent is a tank mix adjuvant that delivers additional Vaporgrip® Technology to spray tanks for further reduction of potential dicamba volatility.

How does VaporGrip® Technology work?

Volatility is the movement of an herbicide as a gas or vapor after spray application. It results from molecules vaporizing into the air after the molecules have settled. We discovered a technology, called “VaporGrip Technology,” that reduces the volatility potential of XtendiMax herbicide by 90% compared to older dicamba products. Click here for a video explaining how VaporGrip Technology works.

VaporGrip® Technology buffers against significant changes in solution pH and prevents the formation of dicamba acid by scavenging extraneous protons.

Is VaporGrip Xtra Agent included in XtendiMax herbicide or is it a separate adjuvant?

The XtendiMax herbicide with VaporGrip Technology formulation already includes VaporGrip Technology in the jug. VaporGrip Xtra Agent is an adjuvant that delivers additional VaporGrip Technology and is added to the spray tank (a separate jug) for further reduction of dicamba volatility.

What is the use rate for VaporGrip® Xtra Agent?

VaporGrip® Xtra Agent should be used at a minimum rate of 20 oz/A.

Has VaporGrip® Xtra Agent been tested?

VaporGrip® Xtra Agent has been thoroughly tested in field trials by Bayer and US academic weed scientists

Can VaporGrip Xtra Agent be used with other dicamba products?

This product can be used with any dicamba product to further reduce volatility potential. VaporGrip Xtra Agent products can be used with XtendiMax herbicide and other low-volatility dicamba products as long as the product is an approved tank mix partner.

Where can growers and applicators purchase VaporGrip® Xtra Agent?

Growers and applicators can purchase VaporGrip® Xtra Agent products through their preferred retailer.

How can grower and applicators make sure they are purchasing a VaporGrip® Xtra Agent product? All VaporGrip® Xtra Agent products will include “VaporGrip® Xtra Agent” as part of their brand name When will VaporGrip Xtra Agent products be available?

VaporGrip Xtra Agent products will be widely available at retailer locations in time for the 2021 spray season.

Where can I find performance data related to VaporGrip Xtra Agent?

You can refer to the VaporGrip Xtra Agent one-pager.

Are there any additional dicamba technologies being introduced in 2021?

Bayer has partnered with Adjuvants Unlimited to provide sprayers with D-Act® Spray System Cleaner, which utilizes Fenton reaction technology. The D-Act Tank Cleaner one-pager can be found here.

Will XtendiMax herbicide be included in BayerPLUS and any other programs?

Bayer will be communicating all programs that include XtendiMax herbicide by mid-November.

Will Bayer offer a Weed Control Guarantee?

Yes, Bayer will offer the 2021 Spray Early with Confidence Weed Control Guarantee. Details can be found here.

Now that EPA has issued a new registration for XtendiMax herbicide and other low-volatility dicamba products, will I get a price reduction from the Plant With Confidence Offer?

No, the Plant with Confidence offer is now cancelled/voided since the EPA has issued a new registration for XtendiMax herbicide and other low-volatility dicamba products prior to February 20, 2021.

What is the latest on XtendFlex® soybeans?

On Sept. 28, 2020, the European Commission authorized XtendFlex soybean technology for food, feed, import and processing in the European Union. This milestone represents the final key authorization for XtendFlex soybeans. With this approval in hand, Bayer can now look forward to a full launch in the United States and Canada in 2021 and expects to be in a strong position to supply 20 million U.S. soy acres. More details can be found here.
