Products Overview

Acuron Flexi - Delivers powerful, broad-spectrum weed control with added flexibility 

Acuron® Flexi corn herbicide delivers broad-spectrum control of tough weeds in corn with added flexibility. Using the latest formulation technology, Acuron® Flexi combines three active ingredients, including bicyclopyrone, and two effective modes of action to deliver a multi-targeted approach to weed control. 

Product Highlights

  • Delivers improved broad-spectrum residual control of many broadleaf weeds and grasses in corn including:
    • Giant ragweed, kochia, marstail, Palmer amaranth and waterhemp
  • Trials show Acuron Flexi delivers improved and more consistent control than competitive herbicide programs 
  • Registered in field corn, seed corn, silage corn, sweet corn (pre-emergence only) and yellow popcorn (pre-emergence only)

Added Flexibility with Acuron Flexi

Not all farming operations function the same. Soil types, tank mix partners and weather conditions can vary. It’s important to have a powerful, robust herbicide that delivers effective, broad-spectrum weed control in all farming operations. 

Application Flexibility Pillar
Excellent pre- and post-emergence crop safety enables application flexibility from 28 days pre-plant up to 30-inch corn
Rotational Flexibility Pillar
Where registered, Acuron Flexi can be used without soil type restrictions
Application Flexibility Pillar
Tank mix compatibility
Does not contain atrazine or glyphosate but can be tank mixed with herbicides based on farming practices



" The most valuable thing I see about Acuron Flexi is that it keeps all the weeds out, I can use it in my areas I can’t put atrazine on, and that I’m applying one time. Acuron Flexi I would definitely use again. It did a very good control on my weeds." 

- Tony Bomkamp, grower, Muscoda, M.N.


"The most beneficial feature of Acuron® Flexi corn herbicide is having multiple modes of action already in the premix and also having the ability to add atrazine where we can. Our customers that have used Acuron Flexi have seen very good performance. We had tough growing conditions this year with too much rain and heat and Acuron Flexi was up to their expectations."

- Mike Anders, grower and retailer, Nerstrand, M.N.
