Protect Profit Through Early Season Weed Control

By Luke Peters
Product Manager, Corn Herbicides

Yield potential can be compromised by weed pressure early in the season. As more weeds survive glyphosate-only applications, it’s vital to implement a herbicide program that uses a residual herbicide to target weeds early on.

By mitigating early season weed pressure, growers can protect corn during critical stages of development, subsequently protecting their yield potential.

Marestail and Palmer amaranth, for example, are two of the most difficult-to-control weeds across the Corn Belt. But with the right herbicide program, they can be controlled.

  • Marestail is generally considered a winter annual weed. However, its germination pattern is starting to shift to spring and summer as a result of cropping systems and herbicide use patterns.1 Using 2.5 pints of SureStart® II herbicide preemergence followed by Durango® DMA® herbicide offers 93 percent control of marestail.2
  • Palmer amaranth started in the south. In recent years, it has been moving into Midwest fields. It has an extended emergence pattern, a rapid growth rate (up to 2 ½ inches per day) and high seed production, averaging 40,000 seeds per plant.3 Because of this growth pattern, controlling Palmer amaranth when it is small is highly important. Using 2.5 pints of SureStart II preemergence followed by Durango DMA offers 99 percent control of Palmer amaranth.2

Control high-anxiety weeds and protect profits this spring with a strong herbicide program. For more information, visit GetMoreTime.com.

Dow AgroSciences Announces Trait Stacking Standards for Enlist™: Advanced Glyphosate Traits Only

Company Accelerates Licensing Efforts, Announces It Will Not Allow Stacking with First Generation Roundup Ready® Trait in U.S.

In accordance with its mission to provide the highest performing products to growers, Dow AgroSciences announced quality standards for glyphosate trait stacking with Enlist. The company said it will allow Enlist to be stacked with advanced glyphosate traits only. It will not allow stacking with the first generation of the Roundup Ready® trait.

“We are committed to optimizing the Enlist system for growers,” says Damon Palmer, Marketing Director, U.S. Seeds, Dow AgroSciences. “We’ve done it with Enlist Duo herbicide with Colex‑DTechnology—a proven, superior herbicide tailored for the grower. Our announcement helps ensure the Enlist family of soybean traits will be stacked exclusively with other industry leading traits.”

The market continues to move to advanced glyphosate traits since they were introduced because they have been proven to outperform the original Roundup Ready trait. Technology with newer glyphosate traits, including Roundup Ready 2 Yield® and Enlist E3 soybeans, show no yield drag or lag.

“Enlist soybeans with Roundup Ready 2 Yield and Enlist E3 soybeans—which feature an advanced glyphosate technology owned by MS Technologies—are our chosen trait platforms moving forward,” says Palmer. “Without question, these are the best trait packages coming to market. Growers should know they can farm with confidence with the Enlist system.”

Update on Licensing: Efforts Intensify as Growers Want Choice in the Market
Dow AgroSciences has been hosting Enlist technology field days and meetings to discuss licensing the Enlist family of traits. Staff from seed companies who sell more than 85 percent of the independent seed company soybean units have attended those events and expressed great interest in licensing the technology, driven largely by the need in the marketplace and grower demand.

Two leading independent seed companies, Stine Seed Company and Merschman Seeds, Inc. have already given their commitment to sell Enlist E3 soybeans. Other leading soybean seed companies have expressed high interest as well.

“We’ve taken a close look at Enlist, and we like what we see,” says Joseph H. Merschman, president and founder, Merschman Seeds, Inc. “It’s a first-class technology. The herbicide is the full package—great weed control and it’s designed to stay where you put it. The traits perform very well and protect the crop. And the germplasm is high quality. That’s the kind of product we want to offer to our growers.”

Farmers who participated in Enlist Grower Research Plots in 2014 overwhelming rated the weed control with Enlist Duo herbicide higher than their current weed control system. In recent market research, more than 90 percent of soybean growers indicated they are interested in trying the Enlist system in soybeans.1

Keep Weeds at Bay This Spring

Protect yield potential and profits by controlling weeds in spring.

Watch how soybean grower George Richter of Edwardsport, Indiana, keeps his fields clean from planting through harvest.

SonicTo control his most troublesome weeds, including marestail, waterhemp and giant ragweed, Richter uses Sonic® herbicide. With the residual control of Sonic, weeds are controlled throughout the season.

This Spring, Protect Nitrogen Below Ground

Nitrogen is critical to crop success. Especially after a short fall, many growers will be applying nitrogen this spring. When spring rain arrives, unstabilized nitrogen can be lost below ground through leaching and denitrification.

Stabilizing applied nitrogen is important regardless of when it is applied. For growers who were not able to apply their nitrogen this past fall, it’s especially important to protect this investment with a nitrogen stabilizer because spring nitrogen losses can significantly reduce the yield potential of corn.

Watch this video to learn the scientific process behind nitrogen loss and see how Instinct® II and N-Serve® nitrogen stabilizers can protect your customers’ applied nitrogen.

Instinct® II approved for use in wheat
Instinct-IIThe Environmental Protection Agency has approved the use of Instinct® II nitrogen stabilizer in wheat. A nitrogen deficiency in wheat fields can cause weed pressure and a decrease in moisture utilization, nutrient uptake, yields, test weight, protein and profits. Instinct II works to keep more nitrogen available at the root zone when used with urea, UAN or manure.

Three Major Steps to Managing Weed Resistance

Since Roundup Ready® crops were introduced, the technology has become the farm industry standard for many growers. But using glyphosate as the primary, or only, herbicide mode of action has resulted in an increase in glyphosate-resistant weeds. In the past year, farmland infested with glyphosate-resistant weeds increased by 20 percent to 84 million acres in the United States.1

As the number of resistant weeds increases, controlling these weeds becomes more complex. New herbicide and trait technology such as the Enlist Weed Control System gives growers an effective tool to use against these herbicide-resistant weeds.

In this video, Andy Asbury, Enlist field specialist, explains how weed resistance spreads and the three major steps to managing weed resistance — following a program approach with multiple modes of action, timely application of herbicides and scouting fields.

Smaller Weeds are Easier to Control

Early season weed activity in your customers’ fields can deprive soybeans of vital soil nutrients and sunlight during key stages of crop development — making it all the more important to control weeds before they emerge.

By applying a residual herbicide in spring, growers can control weeds early, before they compete with the crop. Along with long-lasting weed control, an effective residual herbicide application sets the stage for optimal postemergence herbicide performance later in the season.

Southern Illinois University research shows that a grower can protect 6 bushels per acre by using a pre-post herbicide program versus making the first weed control application with glyphosate when weeds are 4 to 8 inches tall.

sonic_soybeansThis spring, remind your customers of the importance of residual control, especially in soybeans, where there are limited postemergence options. A two-pass program including Sonic® herbicide and Durango® DMA® herbicide provides effective weed control when used in soybean fields.
