Key Steps to Managing Marestail

By Lindsey Hecht, Product Manager, Soybean and Glyphosate Herbicides
Dow AgroSciences

LindseyHechtMarestail is a growing threat to soybean fields. Early control is crucial. A timely burndown application and use of a preemergence herbicide that offers residual control can provide growers with an effective management tool. Marestail has developed a new germination pattern in the last decade and behaves as both a winter and summer annual. It can take nearly a full year to complete its life cycle and has a wide emergence and growth window, which can make it challenging to control, says Joe Armstrong, field scientist, Dow AgroSciences. Growers should consider three practices to manage marestail this year:

  • Year-round scouting. Marestail can grow almost any time of the year and does not stay dormant long. If it grows more than a few inches tall, it is extremely difficult to control, Armstrong says. Therefore, growers should scout for marestail in the spring, early summer and fall. Identify it early when it emerges as a small rosette.

  • Timely application. Control marestail early with a preemergence herbicide such as Sonic® herbicide or Surveil™ Co-pack soybean herbicide. Each has two nonglyphosate modes of action and can be used preplant up to three days after planting. A timely application also opens a wider window for a postemergence application to control any emerged marestail in-crop.
  • Apply a herbicide with residual control. Growers should apply a herbicide that provides long-lasting and effective control of broadleaf weeds. Sonic and Surveil Co-pack can be used preemergence. With a double barrier of residual chemistry, they protect yield potential and manage resistance.

Enlist Duo™ Herbicide With Colex-D™ Technology Moves Forward in Regulatory Process

U.S. Environmental Protection Agency Announces Proposed Decision to Register Herbicide

The Enlist™ Weed Control System from Dow AgroSciences has reached another milestone in the regulatory review process. On April 30, 2014, the U.S. Environmental Protection Agency (EPA) announced its proposed decision to register Enlist Duo™. Enlist Duo is the herbicide for use with the Enlist system.

Enlist_Logo_Horz_TagThe EPA also opened a 30-day comment period, giving growers and others an opportunity to provide input on Enlist Duo herbicide before the agency makes its final registration decision.

Enlist Duo™ is a proprietary blend of new 2,4-D choline and glyphosate. By combining two modes of action, Enlist Duo will control and help prevent further development of herbicide-resistant weeds. The herbicide features Colex-D™ Technology, which will provide stewardship and user benefits, including minimized potential for physical drift, ultra-low volatility, reduced odor and better handling characteristics.

“In its review, the EPA acknowledged the significant scientific advancements Dow AgroSciences made with Enlist Duo herbicide as it relates to off-target movement,” says Damon Palmer, U.S. commercial leader for Enlist, Dow AgroSciences. “Enlist Duo herbicide will help solve the tremendous weed control challenges that growers are facing, and it will do so with technology optimized for on-target application.”

In its “Proposed Registration of Enlist Duo Herbicide” released on April 30, 2014, EPA says it has a “full and scientifically robust data set on 2,4-D” with respect to human health. Regulatory agencies in more than 70 countries, including the United Kingdom, Germany, France, Canada, Japan, Australia and the U.S., have authorized the use of 2,4-D since 2001 using modern regulatory requirements.

The draft label for Enlist Duo™ includes proposed registration for Iowa, Illinois, Indiana, Ohio, South Dakota and Wisconsin. Dow AgroSciences is working with the EPA to expand the list of states in time for the technology’s launch.

Enlist Duo herbicide tailored for modern agriculture
Grower and applicator usability was a primary consideration for Dow AgroSciences in the development of Enlist Duo herbicide. In addition to company and university testing, the first grower-led research plots for the Enlist™ Weed Control System were conducted in 2013.

“For Enlist to be a preferred solution on the farm, it has to be a modern solution — one that advances the farming practices of today,” Palmer says. “The results from this on-farm research activity were consistent with our data, and confirmed the technology consistently performs in real-world scenarios.”

The research plot participants rated Enlist Duo™ in the highest percentile (90 to 100 percent) for broadleaf and grass weed control across all plots. These growers were also asked to evaluate the drift and volatility potential of Enlist Duo™ herbicide with Colex-D™ Technology. Lab and in-field research has shown that using Enlist Duo with Colex-D Technology in combination with a low-drift spray nozzle can decrease physical drift by up to 90 percent when compared with a tank mix of glyphosate and traditional 2,4-D sprayed through a standard XR nozzle. The new Enlist Duo also will have up to 96 percent reduction in volatility compared with traditional 2,4-D products.

Growers participating in the research plots noted the improvements related to off-target movement that they experienced in their trials. “We had Enlist corn planted next to some soybeans. With the constant 6-mile-an-hour wind and the gusts, we could lay Enlist Duo next to the soybeans, and I see no crinkling of the leaves, I see no drift,” says Doug Morrow, Indiana grower and research plot participant.

Resources for responsible use
With the launch of Enlist, growers and retailers will have access to a benefits-based management resource called Enlist™ Ahead. Enlist Ahead will provide best management recommendations that will complement the herbicide label requirements, including the use of a residual, soil-applied preemergence herbicide for weed resistance management.

Comment period opens
To show support for Enlist Duo™ herbicide with Colex-D™ Technology in the comment period, sign the petition at AdvanceFarming.com/petition.htm or leave a comment on the EPA docket.

Pending regulatory approvals, Dow AgroSciences expects to launch Enlist corn and Enlist soybeans in 2015, with Enlist E3™ soybeans and Enlist cotton to follow.

Prepare Sprayers for Effective Herbicide Applications

This spring, take steps to properly prepare sprayers to protect crops and ensure consistent herbicide applications.

Before every application, sprayers should be cleaned to remove any leftover residue from the previous application, says Greg Kruger, associate professor and cropping systems specialist, University of Nebraska.

“A lot of times, we don’t have records or can’t remember the last thing we sprayed, so we want to make sure there’s nothing in the sprayer that could be harmful to the crop coming in,” Kruger says.

Here are some tips for preparing sprayers this spring:

  • Thoroughly clean the sprayer: Refer to labels for information on how to correctly clean tanks and parts, including filters, nozzles, tips and joints.
  • Scout fields early: Applicators or growers should scout fields prior to a herbicide application. Early weed growth and the level of emergence help determine which product is needed and how it should be applied.
  • Select the right nozzle: Once fields are scouted, growers need to use the correct nozzle for application. Growers applying a preemergence herbicide such as SureStart® herbicide for residual control of broadleaf weeds and grasses should use a nozzle that provides a large spray droplet to obtain even coverage.

Growers also can use SureStart for an early postemergence application. When applied postemergence, growers should use an air-induction, extended-range nozzle that produces a slightly smaller droplet size, Kruger says. If there is a dense weed canopy, a residual activity nozzle, such as a turbo-induction nozzle, works best.

Program Approach Is Key to Long-term Herbicide Sustainability

With the increasing number of herbicide-resistant weeds, growers are seeking ways to improve their weed control programs and sustain herbicides for long-term use. Working with growers to develop a program approach will protect the longevity of the chemistries, help prevent weeds from becoming resistant or difficult to control and offer the best results for your customers.

Dow AgroSciences has a long history of promoting herbicide programs, which include applying a preemergence herbicide followed by a postemergence herbicide application. These programs are designed to alternate products with different modes of action, a vital component of this one-two punch to control weeds. To ensure growers are incorporating chemistries from different herbicide groups, check product labels or the Weed Science Society of America website for herbicide class information.

Recent coverage in agriculture publications underscores the value of using a preemergence application followed by a postemergence application for long-term herbicide sustainability. This method offers reliable early season residual control of weeds, and it is a proactive approach to weed resistance management.

Programs that include an effective preemergence herbicide not only provide growers benefits related to weed resistance but also boost productivity by maximizing yields and managing risk. A preemergence herbicide helps minimize the threat of early weeds that compete for nutrients, water and sunlight — all of which are key for good yields. Preemergence herbicides also help minimize risks that come with relying on only postemergence weed control. Weather conditions often can keep farmers and applicators out of the field for long stretches of time, limiting optimum application windows.

This season, encourage your growers to scout their fields early, use recommended label rates and implement a program approach to weed control to help manage weed resistance.
