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 — only available in FiberMax and Stoneville cotton.


BASF will introduce Axant Flex technology for the 2024 growing season. This revolutionary trait package brings forward Axant technology, the newest tool available to cotton farmers. This new system is the best of both worlds for growers, pairing the most comprehensive herbicide trait package available to date with the premier performance of FiberMax® and Stoneville® cotton.


With FiberMax and Stoneville cotton powered by new Axant Flex technology, growers will no longer have to choose between weed control and fiber quality to get the returns they desire.

    With Axant Flex technology, growers can expect:

    • Enabled use of two modes of action, glyphosate and Liberty® herbicide — and anticipated use of Alite 27 herbicide in the future — for more effective control of resistant weeds.
    • Four genetically modified (GM) herbicide-tolerant 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.


    Enhanced Freedom and Flexibility

    As growers well know, the best way to control tough weeds is to ensure they don’t come up at all. Axant Flex technology will bring 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 the most 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.

    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 introduction 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.

    HPPD's in Cotton

    Axant Flex Cotton is tolerant to Alite™ 27 herbicide ​

    • Currently, Alite 27 isoxaflutole herbicide is:
    • • Not available for sale,
    • • Not available in the market, &
    • • Not labeled to use on cotton
    • Other HPPD herbicides (e.g., Laudis, Callisto) can cause significant crop damage to Axant Flex cotton and are illegal to use with cotton.

    • • Solo or tank mix with standard PRE herbicides

    1x rate/A

    • • Cotyledon to 4-leaf
    • • At emergence, application provides opportunity to delay the PRE application if rain is not expected soon after seeding
    • • A knockdown herbicide will need to be added if weeds are present
    • • Alite 27 herbicide may be tank mixed with glyphosate and Liberty herbicide 
    • • Standard BASF and other POST herbicide registered for use in cotton can be used

    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

    After EPA approval of Alite 27 herbicide (EPA Reg. No.7969-433) registration allowing use on isoxaflutole-resistant cotton, Alite 27 herbicide may only be used on GT27 or isoxaflutole-resistant soybean or isoxaflutole-reisistant cotton. Crops not containing a gene expressign an HPPD protein will not be tolerant of Alite 27 herbicide.
