When planning herbicide strategies, especially in areas with significant resistant weed populations, you can help growers develop a program approach, starting with broad-spectrum soil residual herbicides offering multiple modes of action. This early season control allows growers to plant their entire crop and then come back with timely applications of effective postemergence weed control solutions.
Remind growers it’s critical to scout fields and make applications when weeds are small and actively growing. Last year pointed out the value of controlling weeds early in the season.
In 2015, many growers experienced heavy weed pressure, mainly because of excessive rainfall and wet field conditions that delayed or prevented application of residual herbicides. This led to substantial weed populations that produced a multitude of seeds that may emerge in 2016.
The first year after a big flush of weeds is the most challenging. Even one year of poor weed control can be costly to overcome. That’s why it’s important to build and carry out a comprehensive weed control program. Growers should understand the weed spectrum in each field and build a plan designed to control weeds early. You can help growers put a weed control plan in place that gives them options to adjust to changes such as weather delays or weed escapes.
Preemergence herbicide applications — including a burndown — create a clean field at planting and offer control of early season weeds, eliminating weed competition during the crop’s critical early growth. In areas with significant resistant populations, growers can adopt a program approach that starts with broad-spectrum soil residual herbicides offering multiple modes of action. Sonic® or Surveil® herbicide in soybeans and Resicore™ or SureStart® II herbicide in corn are products to consider for early residual control.
The Enlist™ weed control system includes timely postemergence applications of Enlist Duo® herbicide at the full label rate. This provides an additional mode of action beyond a glyphosate-only program to help control the toughest weeds, including resistant and hard-to-control species.
Enlist corn, soybeans and cotton are tolerant to Enlist Duo herbicide, a proprietary blend of glyphosate and new 2,4-D choline. (Enlist Duo is not yet registered for use on Enlist cotton.)
With two modes of action, Enlist Duo helps control resistant and hard-to-control weeds. Be sure to follow label directions for application. Full label rates will help control the toughest weeds, including Palmer amaranth, marestail and waterhemp.
Help growers who turn to you for advice by recommending effective weed control strategies. When challenging weeds are present in a field, growers who use a system approach will be better able to control those weeds while preserving valuable herbicide tools for future crops.

Weather challenges in 2015 illustrate the value of building and following a program approach to weed control. Using the Enlist™ weed control system, including timely postemergence applications of Enlist Duo® herbicide at full label rates, will help control the toughest weeds.
