Knowing where compatible and susceptible crops are planted nearby will help farmers maximize the benefits of herbicide trait technologies, including the Enlist™ weed control system. Josh Wilson, Enlist field specialist, says it’s important to read and understand label requirements and make plans concerning crop placement.
“To be successful with herbicide trait technologies, farmers need to know when and how to apply them,” Wilson says. “They also need to understand which crops will be planted nearby. Implement strategic field planning and plant herbicide-tolerant crops where you can maximize the system by using the herbicides to their best advantage.”
Wilson urges farmers to talk to their neighbors and find out what kinds of crops they’re planting on surrounding acres. Also talk with non-farming neighbors to know where susceptible gardens and ornamental plants are located.
Know the difference
Application of Enlist herbicides near compatible crops is relatively straightforward: There are no wind directional application restrictions with compatible crops, such as soybeans without the Enlist trait, corn, rice, peanuts, sorghum and alfalfa. You can apply Enlist herbicides when wind is blowing toward them.
“Also understand where susceptible crops — especially non-Enlist cotton — are planted,” Wilson says. Susceptible crops, as defined on the Enlist™ herbicide labels, have a low natural tolerance to exposure to 2,4-D. “Follow the labels for Enlist herbicides and do not spray when a susceptible crop is adjacent downwind. Spray only when the wind is blowing away from susceptible crops,” Wilson says.

Once you’ve planted Enlist crops — Enlist E3™ soybeans or Enlist cotton — make sure to check weather conditions before spraying Enlist™ herbicides. Time applications to hit weeds when they’re small, actively growing weeds less than 6 inches tall and apply when conditions will limit drift potential.
Use multiple sites of action
Remember Enlist cotton and Enlist E3™ soybeans are tolerant to three herbicide sites of action: 2,4-D choline, glyphosate and glufosinate.
“The best results will occur when farmers can apply Enlist and Liberty herbicides to the same field,” Wilson says. “They can use a tank mix of Enlist One and Liberty herbicides or make planned sequential passes of Enlist Duo herbicide and Liberty herbicide. Using both technologies not only offers the best weed control potential for the current year, it also helps curb the development of resistant weeds. This prolongs the efficacy of these herbicides for coming years.”
Planning is essential to making sure your herbicide trait technology works this coming year and in future years.
- Talk to neighbors to find out what’s growing nearby.
- Know the field history.
- Use traits that allow you to apply herbicides that are effective on the challenging weeds in your fields.
- Adopt a zero-tolerance policy for weeds.
- Be good stewards of effective herbicides.
- Scout for weeds before and after application. If you see escapes, consider adjusting your weed management plan for better control in the future.
