Brake Herbicide. Stop Palmer in its Tracks.

Coming Soon!

Meet the squadron of new pre-emergent herbicides for cotton. Brake® (active ingredient fluridone) brings a new mode of action to fortify your arsenal in the fight against glyphosate-resistant Palmer amaranth (pigweed) in cotton.

Section 18’s are pending in several states. Check back often for updates to approved counties and other formulation-specific information.

Brake Formulations

Introducing three formulations - Through the work done with farmers during the last three years under Section 18 authorizations, with support from research and development efforts, continuous improvements in the use of Brake have been made each year. In 2015, there will be as many as three different formulations of Brake. The different formulations combine another herbicide mode of action with Brake to maximize the pre-emergence performance, crop safety, and versatility in the different regions.

Brake F2 is pending Section 18 Emergency Exemption requests and authorizations for use in select counties in Arkansas, Missouri, and Tennessee. Brake F2 contains 1.6 pounds fluridone and 1.0 pounds fomesafen per gallon.

Brake F16 is pending Section 18 Emergency Exemption requests and authorizations for use in select counties in Georgia, North Carolina, and South Carolina. Brake F16 contains 1.2 pounds fluridone and 1.5 pounds fomesafen per gallon.

Brake FX is a combination of fluridone and fluometuron pending Section 18 Emergency Exemption requests and authorizations.

The spread of glyphosate-resistant Palmer amaranth has put extreme pressure on weed control systems and brought a renewed interest in the development of alternate herbicides for cotton. Since 2012, SePRO Corporation has worked in conjunction with the USDA and Cotton Incorporated to conduct research with Clemson University, the University of Georgia, North Carolina State University, the University of Tennessee, Mississippi State University, the University of Florida, the University of Arkansas and others as part of a Cooperative Research Program. The Brake herbicide system has been developed to provide a sustainable herbicide strategy for cotton featuring a new mode of action with resistance management as a primary goal.
