Liberty Herbicide Works, But You Must Manage Correctly

The Mid-south now leads the world in herbicide-resistant weeds, with 10 glyphosate- resistant weeds species confirmed.

With glyphosate-resistant Palmer amaranth becoming more prevalent, Tennessee cotton producers have moved from a glyphosate-based weed management system to a Liberty-based weed management system in the last five years.

The Liberty system includes pre-plant, pre-emergence and post-directed applications of other herbicides besides Liberty to be successful. This system has for the most part controlled weeds, particularly Palmer, but it is not as inexpensive or easy as when glyphosate still controlled Palmer amaranth.

"Remember Roundup could kill any Palmer pigweed at any height, and it was money before resistance came into play," said Steckel. "That is not the case with Liberty. You really have to manage it to make it work."

The Mid-south now likely leads the world in herbicide-resistant weeds, with 10 glyphosate-resistant weeds species confirmed in the region.

During his presentation "Uses and Caveats With Liberty Herbicide on Liberty Link and WideStrike Cotton Cultivars" at the Cotton Incorporated Crop Management Seminar in Mississippi, Steckel outlined strategies to effectively use Liberty in today's resistant world.

In the past, Cotton Incorporated's bi-annual Crop Management Seminar talks were featured in static PowerPoint slides, where users could glean information but not get the full impact of what was discussed. Now that static offering has been upgraded to a multimedia experience.

Growers, consultants, and other cotton industry professionals who missed the CMS, held in Tunica, Mississippi, can now view and listen to the presentations from the comfort of their own homes—at any day and time they like.
