A Trait Stack with 

Next-Level Solutions

We know how important it is for growers to protect their fields from resistant weeds. That's why BASF is excited to introduce Axant Flex herbicide  trait technology — cotton's first and only quad-stacked herbicide trait package.


Powered by a new HPPD-resistant trait, Axant Flex technology is anticipated to be available with Alite 27 herbicide for the 2024 growing season, pending regulatory approvals.This revoultionary trait package brings forward Axant technology — the first HPPD-resistant trait in cotton — to deliver a new site of action that better combats herbicide reisistance from troublesome broadleaf weeds, both pre or early post with Alite 27 herbicide.  Axant technology is also the first cotton trait to enable the use of HPPD residual herbicides, providing growers more freedom and flexibility for effective post-emergent applications. This new system is the best of both worlds for growers, pairing the most comprehensive herbicide trait package ever with the premier performance of FiberMax® cotton and Stoneville® cotton.


With Fibermax and Stoneville cotton seed powered by new Axant Flex technology, growers will no longer have to face the tradeoff between weed control and fiber quality in order to get the returns they're looking for.


With Axant Flex technology, growers can expect:

  • Newly enabled use of our four different modes of action — Alite 27, Engenia® herbicide, Glyphosate, and Liberty® herbicide — for more effective control of resistant weeds
  • Four genetically modified (GM) herbicide-tolerate traits — Axant, XtendLink, GlyTol® and LibertyLink® traits — introgressed into high-yielding genetics.
  • Greater flexibility and choices in pre or post-emergent weed control programs
  • Best-in-class germplasm combined with native traits that protect yield and fiber quality


First and only quad-stack in cotton

Enhanced Freedom and Flexibility

As growers well know, the best way to control tough weeds to ensure they don't come up at all. Axant Flex technology brings a new site of action and first-of-its-kind solution to more effectively combat herbicide-resistant broadleaf weeds, including Palmer amaranth and grasses. Backed by this advanced science, Axant Flex technology provides growers with a variety of groundbreaking benefits, such as:

  • Getting Ahead of Palmer Amaranth

Rapid seed germination and early seedling growth make Palmer amaranth tough to control. But Palmer amaranth is vulnerable during its seedling stage, making a pre-emergent like Alite 27 herbicide ciritical in getting ahead of its growth.1

  • Early-Season Flexibility

Alite 27 herbicide, an HPPD herbicide chemistry, provides more flexibility for growers earlier in the season at themost critical stage of cotton growth. Alite 27 herbicide can be applied PRE or EARLY POST, as well as tank mixed with other residual  and knockdown herbicides to work within their weed management program.1

  • Wider Weed Control Window

The use of Alite 27, a HPPD residual herbicide, provides early control, giving cotton growers peace of mind and a widened weed control window to address post-emergent issues without the need to rush back into the field.

  • Manages Future Resistance

Utilizing multiple modes of action is one of the most powerful tools a grower has to forestall weed resistance. The introduction of a new mode of action in cotton herbicides will help fight the development of future resistance and increase the diversity and sustainabilty of weed management programs.

  • More Stable Yield

Because of Alite 27 herbicide's strong residual activity, a half-inch of rain is needed to recharge. This residual activity keeps fields cleaner and helps cottonseed with Axant Flex technology deliver better and more stable yield and fiber quality even in arid regions.1

A Tradition of Advancement

For generations, BASF has built a legacy of innovation by bringing new technologies to market – including seeds and traits, chemical and biological crop protection, soil management, Plant Health, pest control and digital farming. The launch of Axant Flex technology marks the latest chapter in our story of providing cotton growers with agronomic solutions that help drive their business and the cotton industry forward.

Always read and follow label directions. Alite 27 is a U.S. EPA Restricted Use Pesticide. Alite is a trademark of BASF and is pending resgistration for use in cotton. Axant is a trademark of BASF for the HPPD tolerant trait. The trait is pending regulatory  approval for commercialization in cotton. Engenia herbicide and Alite 27 are U.S. EPA Restricted Use Pesticides. Additional state restrictions may apply. Approved pH buffering adjuvant required with every Engenia application.

Built-in Technology for Future Control


At post-registration, a portion of cotton acres in the U.S. are expected to be enabled for Alite 27 herbicide. Axant Flex technology brings built-in technology for future control of resistant weeds as more acres are approved by the U.S. EPA for Alite 27 herbicide use, contingent on EPA-approved label amendments.1
