Build Your Best Herbicide Program
Crop Program Recommendation
Our program recommendation will guide you to the right program for your acre. Get the best control of tough and resistant weeds with the optimal herbicide program for your acres.
Soybean (Enlist E3)
By using Liberty ULTRA herbicide as part of the Enlist® E3 system, farmers will obtain superior weed control and do their part to sustain long-term efficacy. Give farmers the best control of tough and resistant weeds. Additionally they should include layering their residual herbicides and incorporate multiple, effective herbicide modes of action (MOA).
Soybean (XtendFlex)
LIberty ULTRA herbicide should be used as part of of the total XtendFlex® system approach with the addition of pre and post residual herbicides as well as multiple, effective herbicide modes of action (MOA).
Cotton
Liberty ULTRA herbicide is available for across today's cotton trait platforms, including Axant™ Flex, Enlist®, GlyTol®, LibertyLink® and XtendFlex®, and should be used as part of a comprehensive, integrated weed management program that includes pre- and post-residual herbicides.
Canola
Liberty ULTRA herbicide use on InVigor® canola hybrids with the LibertyLink® trait provides an excellent means for growers to rotate non-selective herbicide systems to effectively manage tough-to-control weeds.
Corn
The LibertyLink® system couples high-performing genetics with the superior performance of Liberty® ULTRA herbicide, resulting in superior weed control of tough-to-control and resistant weeds for high corn yields that deliver.

What are the appropriate mixing instructions for Liberty ULTRA herbicide (by crop)?
Mixing order matters when preparing your spray solution to avoid unintended consequences of incompatible products, resulting in inconvenient downtime. A great way to remember the proper mixing order is to follow the D.A.L.E.S. method: dry products first, followed by AMS, liquid and SC herbicide formulations, emulsifiable concentrates and, lastly, surfactants.
What are the recommended nozzles to use for the best coverage of Liberty ULTRA herbicide (by crop)?
When it comes to nozzle selection, speed and pressure should drive your nozzle choice for the best coverage. For Liberty ULTRA herbicide, that means a nozzle that provides medium- to coarse-size droplets for uniform and thorough weed coverage, such as the examples in the table below.
What is the best time of day to spray Liberty ULTRA herbicide?
Liberty ULTRA herbicide is a light-activated herbicide, which means the time of day you apply is important to maximize efficacy of application. While higher temperatures and relative humidity are also important, sunlight is the main driver of Liberty ULTRA herbicide activity in weeds and its overall effectiveness. Ideal timing for Liberty ULTRA herbicide is two hours after sunrise and two hours before sunset.
