4 steps to keep herbicide applications on target

Herbicide drift is something all farmers want to avoid. Luckily, with the right trait technology and steps for precision applications, you can get on-target, effective weed control.

Enlist® Herbicides vs. Generic 2,4-D

The trait technology in the Enlist® weed control system provides effective weed control plus herbicides with near-zero volatility. Enlist E3® soybeans offer tolerances to 2,4-D choline, glufosinate and glyphosate, while Enlist® corn offers the same plus an additional tolerance to FOP herbicides.

Enlist One herbicide and Enlist Duo herbicide are the only 2,4-D products labeled for use on Enlist crops and for good reason,” says Iowa-based Enlist® field specialist Scott Jungman. “When compared with generic 2,4-D formulations, Enlist herbicides are significantly less likely to move off target. Herbicide drift makes weed control less effective and can damage vulnerable crops, creating the potential for serious penalties.”

Jungman explains what sets Enlist® herbicides apart from generics: “Enlist herbicides contain 2,4-D with Colex-D, a novel drift-reduction technology that makes spray droplets significantly less likely to drift. When used according to label, Enlist herbicides land and stay on target, without requiring additional drift control agents.”

Here are a few stats that set Enlist herbicides apart:

  • 2,4-D choline is 96% less volatile than 2,4-D ester.

  • 2,4-D choline is 88% less volatile than 2,4-D amine.

Enlist® Herbicides vs. Dicamba

Jungman says Enlist herbicides provide several advantages over dicamba : “For one, the 2,4-D choline in Enlist herbicides is 236 times less volatile than dicamba.”

Enlist herbicides offer these additional benefits over dicamba:

  • No calendar cutoff dates

  • Greater flexibility with key tank-mix partners, including AMS

  • No drift-/volatility-reducing adjuvants required.

“Finally, soybeans of any trait technology are not susceptible to Enlist herbicides,” Jungman says. “The same is not true of dicamba.”

Jungman says dicamba drift has caused damage — and even yield loss — across the Corn Belt. However, when used correctly, the Enlist® system prevents these issues while providing effective control of tough weeds.

Tips for On-target Applications

While Enlist herbicides offer near-zero volatility, Jungman says, it’s still essential to follow best practices for on-target applications. Here are four tips for success:

  1. Confirm proper field placement. “As with any herbicide, read the label first. Then find out what’s growing nearby to ensure proper placement. Many crops, including corn, soybeans and sorghum, are not susceptible to Enlist herbicides. However, you may be near susceptible crops like tomatoes, watermelons or pumpkins,” Jungman says. “Talk with neighbors to see if they plant susceptible crops close by and work together to prevent damage.”

  2. Set up your sprayer correctly. “The sprayer and nozzles are critical to maximizing coverage while minimizing drift potential,” Jungman says. “Use qualified nozzles and pressure combinations, and adjust for correct spray rate, spray volume and boom height.”

  3. Watch weather conditions. “Target applications of Enlist herbicides when wind speed is greater than 3 mph, but less than 10 mph. And remember, only spray when the wind is blowing away from susceptible crops,” Jungman says. “Additionally, if the weather is hot and dry, consider increasing spray water to around 20 gallons per acre for better coverage.”

  4. Do not apply during temperature inversions.Temperature inversions trap herbicide particles in a layer of warm air, which can move off target once the wind picks up,” Jungman says. “Remember: Temperature inversions typically occur between dusk and dawn and when there is very little wind movement. That’s why applying during wind speeds between 3 and 10 mph is critical.”

Jungman also advises reading the latest Enlist® Product Use Guide to ensure precision applications. For  more resources to keep weed control on target this season, visit the On-target Applications page at Enlist.com.
