You have a lot of choices to make each year, and thorough weed management plans are at the top of your list. As you battle tough, resistant weeds like waterhemp or Palmer amaranth, choosing the right trait platform is critical to help you enable the best solutions to manage those weeds. Shawna Hubbard, Corteva Agriscience Enlist™ herbicide product manager, emphasizes the Enlist weed control system is a solution built for you to take down your toughest weed challenges.
“Enlist E3 soybeans and Enlist cotton are tolerant to three postemergence herbicides featuring different sites of action: 2,4-D choline, glyphosate and glufosinate — the active ingredient in Liberty herbicide,” Hubbard says. “This allows farmers to use multiple sites of action in one pass.”
If you’re planting Enlist E3® soybeans or PhytoGen Enlist® cotton this year and need to control waterhemp or Palmer amaranth, Hubbard recommends a postemergence tank mix of Enlist One® and Liberty® herbicides. With this tank mix, you can spray on your schedule with no calendar cutoff dates — through R1 on Enlist E3 soybeans and early bloom on Enlist cotton.
“A tank mix of Enlist One and Liberty herbicides is the most effective and powerful postemergence treatment to control weeds like Palmer amaranth, waterhemp and kochia,” Hubbard says. “In 2020 trials, we saw this tank mix dominate waterhemp and Palmer amaranth.”
Hubbard stresses three important factors to achieve these results:
The flexibility of Enlist One herbicide lets you customize a program approach to weed control. With a tank mix of Enlist One and Liberty herbicides, you get two modes of action working together to tackle the same weed without the concern of acidification in the tank. That means you get powerful weed control without impacting the inherent near-zero volatility of 2,4-D choline in Enlist One herbicide.
To optimize this tank mix, ensure you’re following these guidelines before you spray this season:
Liberty herbicide is the preferred glufosinate of the Enlist weed control system to allow farmers more flexibility and weed control options.
