Steve Crawford of Corteva Agriscience shows the difference a program approach makes on weed control. The untreated check is overrun with grasses and broadleaf weeds, especially pigweed. However, with Enlist One® herbicide as the cornerstone of a program approach, the treated rows of Enlist E3 soybeans are weed free.
For successful control, it’s critical to prevent weeds from getting a foothold. Dan Puck, Enlist™ field specialist, says it’s vital to start clean. He says you can accomplish this in Enlist E3® soybeans with a burndown application, with tillage or with a combination of both.
“Any time you can plant soybeans in a clean field, it helps,” Puck says. “You can follow up with a quality residual herbicide program. Residuals provide a blanket of protection as well as allow you to bring more sites of action to your weed control efforts.”
Quality residuals set up a successful postemergence program.
“Make timely postemergence applications, when weeds are small and actively growing,” Puck says. “Always plan to spray weeds before they exceed 6 inches tall. That’s almost exactly the length of a dollar bill.”
Following a carefully timed program approach leads to great results, Puck says. He emphasizes the value of multiple sites of action.
“Each site of action attacks weeds differently,” he explains. “The more sites, the more confident a grower can be about staying on top of weeds.”
Farmers are succeeding with programs that employ three, four, five or even more sites of action. Solid weed control helps preserve yield potential. It also gives weeds less opportunity to develop resistance.
Enlist E3 soybeans give farmers flexibility in creating an effective weed control program.
“Farmers can use trusted residual herbicides such as Sonic, Trivence or Surveil,” Puck says. “Enlist E3 soybeans are tolerant to three herbicides with different sites of action: 2,4-D choline, glyphosate and glufosinate.
“This offers a huge advantage,” he continues. “It gives you some great post options. For instance, you can use Enlist One® herbicide tank-mixed with Liberty herbicide or Durango DMA. Another example is Enlist Duo, which is a combination of 2,4-D choline and glyphosate.”

Season-long weed control is challenging. The Enlist™ weed control system offers unbeatable flexibility to farmers who need to get a handle on tough and resistant weeds.
Enlist herbicides are the cornerstone of an effective program approach to weed control. By employing multiple sites of action throughout the growing season, users can keep weeds at bay all summer long.
An important part of a successful program approach is the use of residual herbicides to keep the field clean until the applicator can make timely postemergence applications, says Scott Jungman, an Enlist™ field specialist.
“We recommend growers who plant Enlist E3 soybeans use a preemergence herbicide such as Sonic, Trivence or EverpreX,” Jungman says. “Then, during postemergence application, include a qualified s-metolachlor such as EverpreX or a qualified acetochlor. That provides overlapping residual coverage to keep weeds under control.”
Enlist crops are tolerant to three sites of action: 2,4-D choline, glyphosate and glufosinate. Enlist Duo® herbicide is a convenient combination of 2,4-D choline and glyphosate, providing two sites of action postemergence. Enlist One® herbicide is a straight-goods 2,4-D choline. Jungman said farmers should always tank-mix Enlist One with an additional site or sites of action for better weed control and to limit potential for weeds to develop resistance.
“We recommend tank-mixing Enlist One with either glyphosate or Liberty herbicide,” he says. He emphasizes that Enlist One is compatible with other tank-mix partners as well. Go to EnlistTankMix.com for the complete list.
Many farmers appreciate the wide application window they get with Enlist herbicides.
“Enlist One and Enlist Duo are not restricted-use herbicides,” Jungman says. “They can be applied to Enlist E3 soybeans through the R2 stage, while Liberty can only be applied to glufosinate-tolerant soybeans up to the R1 stage. This gives growers an extra 7 to 10 days to make an effective application with Enlist herbicides.”
“Another key advantage is that soybeans are a compatible crop,” Jungman points out. “Farmers can spray Enlist herbicides next to non-Enlist soybeans – or corn or alfalfa or any other compatible crop – without worrying about damaging those neighboring fields.
“Stay within the wind speed window of 3 to 10 mph and make sure the wind is not blowing toward a susceptible crop,” he says. “If any listed susceptible crop is downwind, don’t spray.”
