Trials For Enlist System Demonstrate Excellent Weed Control

New data from 2011 field trials across the Midwest demonstrate the Enlist Weed Control System provides control of major, tough weed species, including glyphosate-resistant Palmer amaranth, waterhemp and giant ragweed. The results, generated from 33 field trials and presented at the Weed Science Society of America (WSSA) annual meeting, again proved the efficacy of the Enlist system.

Pending regulatory approval, the Enlist system will build on and sustain the glyphosate-tolerant trait system. Enlist is a new herbicide-tolerant trait technology for corn, soybeans and cotton, that will provide tolerance to Enlist Duo herbicide with Colex-D Technology. Enlist Duo is a proprietary blend of glyphosate and new 2,4-D choline.

Results from field trials conducted by Dow AgroSciences and university collaborators showed broad-spectrum weed control. The best overall weed control was achieved with a program approach, including a soil-applied, preemergence residual herbicide followed by the Enlist herbicide solution.

This approach led to 99% control of glyphosate-resistant Palmer amaranth, and 100% control of red root pigweed, glyphosate-resistant common ragweed, giant ragweed and glyphosate-resistant waterhemp in Enlist corn.

“We put the Enlist system through rigorous testing again in 2011, and it came through with the exceptional control we expected,” says Mark Peterson, Dow AgroSciences global biology leader, Enlist Weed Control System. “The results also demonstrate the benefits of a program approach to weed management that includes multiple modes of action and foundation herbicides.”

Data Show Control Of Resistant Weeds In Corn

In corn, scientists performed trials with the Enlist herbicide solution applied postemergence following preemergence applications of SureStart herbicide, or tank-mixed with SureStart and applied to corn postemergence. These multiple mode of action programs provided exceptional control of hard-to-control and resistant weeds.

  • Programs using SureStart and the Enlist herbicide solution resulted in 100% control of glyphosate-resistant waterhemp, outperforming all other applications that included glyphosate over the top of the crop.
  • The Enlist herbicide solution improved control of several key weed species versus glyphosate alone in comparable treatments at all application timings.

97%-100% Control Of Glyphosate-Resistant Pigweed In Soybeans

For soybeans, scientists compared postemergence applications of glyphosate alone and the Enlist herbicide solution only. They also compared preemergence residual herbicide applications followed by the Enlist herbicide solution, and preemergence residual herbicides followed by glyphosate alone.

  • The two modes of action of the Enlist herbicide solution provided broader spectrum and more complete control of key weed species compared to postemergence applications of glyphosate only.
  • A preemergence residual herbicide application followed by a post-application of the Enlist herbicide solution resulted in 97% control of glyphosate-resistant pigweed and 100% control of glyphosate-resistant giant ragweed. This compares with 77% and 89% control, respectively, with a preemergence herbicide followed by postemergence applications of glyphosate alone.

“These studies confirm the Enlist system will deliver on its promise to control tough weeds for maximum yield potential,” Peterson says. “When available, the Enlist system will improve and sustain the long-term viability of the glyphosate system.”

The Enlist system combines herbicide-tolerant traits that will enable the use of a new 2,4-D choline, glyphosate, glufosinate (in soybeans and cotton) and FOP chemistries (in corn) to combat a wide range of weed pressures.

Pending regulatory approvals, the Enlist system will be available in corn in 2013, followed by soybeans in 2015 and cotton in 2016.
