Help farmers stay the course even in challenging conditions

By: Jeff Moon, market development specialist, Corteva Agriscience, Agriculture Division of DowDuPont        

Last fall’s weather conditions and late harvest had a big impact on soybean farmers. Combine that impact with current economic issues, and they are likely feeling the pinch of limited dollars for inputs this spring. While the temptation for many is to rethink or even cut back on weed control plans, retailers should be ready to help farmers stay the course to keep yield potential intact.

That’s especially true as weed pressure in many areas is as strong as ever, thanks to an influx of tough winter annuals like marestail. Germinating during last fall’s favorable conditions, they’ve overwintered to reemerge in force this spring. To make matters worse, this spring has seen another round of cool, wet conditions to further saturate soils in many areas — pushing back planting and allowing weeds extra time to grow into problems.

Having a strategic weed control plan in place that accounts for potentially challenging conditions allows you and your customers to make adjustments instead of rash decisions. For example, fewer input dollars or a tighter planting window might tempt some farmers to skip preemergence herbicide applications and concentrate only on a postemergence program. But many of today’s toughest weeds are very difficult to control with only postemergence applications. As the season progresses, farmers will be unable to catch up with these weeds, and the real pain could come at harvest.

Instead, developing a strategic weed control plan and then staying the course provides the best opportunity for maximum yield at season’s end. Consider starting with a preemergence herbicide in early spring to keep weeds small and easier to control. In soybeans, Sonic® herbicide when applied as a preemergence provides broad-spectrum, residual control, making postemergence applications more effective. And Sonic is flexible enough to be applied either pre- or postplant. This helps growers plant whenever the field is fit.

When cool, wet spring conditions make it difficult to apply early season herbicides, another effective option is Trivence® herbicide, which combines burndown of emerging weeds with residual control that lasts through crop emergence.

Farmers should then layer residual herbicides to help keep fields clean longer, typically through crop canopy closure. In soybeans, follow Sonic herbicide with a postemergence product, such as DuPont EverpreX® herbicide, and consider adding glyphosate or fomesafen for even more modes of action.

Sound advice is the bedrock of your customer relationships. Having a strategic weed control plan in place allows you to more easily guide farmers through conditions like we’re seeing this season and serves to solidify those relationships. Weeds are relentless year after year, and the ability to act early and often against them keeps farmers ahead during the season, all the way to harvest.

Ramping Up Enlist E3™ Soybean Offerings for Your Customers

By: Shawna Hubbard, herbicides product manager, Corteva Agriscience, Agriculture Division of DowDuPont          

Shawna Hubbard

In January, we got some tremendous news for soybean farmers. Enlist E3 soybeans received import authorizations from China and the Philippines, and we announced launch plans. Commercial volumes of Enlist E3 soybeans are available now.

This summer, we’ll be able to help more farmers get a first-hand look at the Enlist system, including Enlist herbicides, and the differences this weed control system offers. We’re expanding grower experiences with demonstration plots, field technology days and other education activities.

Robust ramp-up plans are underway, including extensive seed production to ensure that Enlist E3 soybeans are broadly available to farmers in 2020.

To bring this important technology to more farmers, we’ll broadly license Enlist E3 soybeans to the industry. In 2020, we expect to achieve 10 percent market share in soybeans thanks to the performance and weed control advantages possible with Enlist E3 soybeans.

Weed control and crop performance
It’s important to understand Enlist E3 soybeans offer more than exceptional weed control: These soybeans deliver excellent yield potential. Enlist E3 soybeans provide the most advanced trait technology for a new standard of weed control and yield performance.

Growers can preserve more of the yield potential of an Enlist E3 soybean variety by eliminating weeds – using Enlist herbicides as the cornerstone of a full weed management program approach – and retaining more natural resources for the crop. Because of our industry-leading breeding program, Enlist E3 soybeans will be in elite genetics and will be available in a range of maturities.

Finally, Enlist herbicides provide growers peace of mind. Enlist herbicides contain 2,4-D choline with Colex-D® technology to deliver near-zero volatility and reduce drift. Farmers are realizing these products stay where they’re sprayed. Growers who follow the label are building confidence in the efficacy and ease of use with the Enlist system.

Planning a program approach
You can help your growers stay ahead of weeds by planning a season-long strategy for weed management. Start clean with a burndown application. Consider Elevore® herbicide with Arylex® active to help customers get the season started right. Follow with effective residual herbicides: The Corteva portfolio includes Sonic®, Trivence® and EverpreX.

Finally, make timely postemergence applications of an Enlist herbicide when weeds are small and actively growing. Using multiple modes of action improves weed control. Enlist herbicides give your customers the flexibility of additional postemergence modes of action. Enlist Duo® herbicide conveniently combines 2,4-D choline and glyphosate. Or you may suggest growers use Enlist One herbicide for additional tank-mix flexibility to target specific weeds, including those susceptible to glufosinate.

Retailers can take advantage of many online tools, including the Product Use Guide, Sprayer Cleanout Guide, Application Guide and the Enlist Ahead detailer, which includes information on the Enlist Ahead app, incentives and other benefits.

Tips for finding the right corn herbicide program for your customers

By: Lyndsie Kaehler, U.S. Corn Herbicides Product Manager, Corteva Agriscience, Agriculture Division of DowDuPont   

Lyndsie KaehlerWinter is an opportunity to reflect and make plans for the upcoming season. Since every farmer, field and season is different, retailers are challenged to develop customized weed control programs to fit customers’ unique needs each year. As you create 2019 corn herbicide plans, here are three key areas to consider.

Attack weeds early and often.
Give your customers’ corn the strongest start possible by layering residual herbicides to control tough weeds. Uncontrolled weeds steal crucial nutrients, sun and water from young corn plants and ultimately, rob yield. Some of the fiercest weed competition, such as marestail, waterhemp and Palmer amaranth, have long germination periods and spread to more fields each year.

Start with a preemergence herbicide to control early weed flushes. Then, come back with a postemergence residual herbicide to control weed escapes and prevent competition from later-emerging weeds.

Recommend corn herbicides with ultimate dependability.
The corn herbicides portfolio of Corteva Agriscience, Agriculture Division of DowDuPont, is designed to fit the way farmers grow corn, so they can spend less time worrying about unwanted, yield-robbing weeds. Our corn herbicides offer dependability and application flexibility to deal with the unexpected. Here is a quick look at how each product can help your customers:

  • Resicore® herbicide is effective, with versatile application timing and residual control lasting deep into the growing season.
  • SureStart® II herbicide is proven to control weeds when it matters most — during the early developmental stages of corn growth.
  • DuPont Realm® Q herbicide is a great postemergence option with multiple modes of action and built-in safener technology that can be applied under diverse weather conditions.
  • Keystone® NXT herbicide is consistent, providing a wide spectrum of weed control, and only requires ¼ inch of rain to activate.
  • DuPont Cinch® ATZ herbicide delivers peace of mind and flexibility through early weed control, especially for farmers needing rotational flexibility.

Offer new savings for your customers
These corn herbicides are part of the all-new, rebate-free TruChoice® offer. You can register at truchoiceonline.com to learn about two ways to offer farmers upfront savings on their crop protection and qualified seed purchases. It can help build your business while improving customers’ cash flow. 

We look forward to working with you this season. Talk with your territory manager from Corteva Agriscience about finding the right corn herbicide for your needs.

Control high-anxiety weeds through fall burndown treatments

Kent Bennis

Kent Bennis, market development specialist, Corteva Agriscience, Agriculture Division of DowDuPont

Fall often consists of reflection and planning for your customers. This entails evaluating their current season and preparing for the next. However, for many soybean farmers in the Midwest, fall is also the time they may be experiencing the pain of actively growing weeds, including marestail.

We highly recommend that your customers implement fall burndown treatments to help ease their weed anxieties. Specifically, postharvest burndown treatments can reduce customers’ worries by providing thorough weed control in recently harvested fields. And when farmers combine a fall burndown treatment with a spring residual herbicide, they will experience cleaner fields through planting.

Here are some key benefits of fall burndown treatments to share with your customers:

  • Lessens weed pressure so fields are ready to plant as soon as farmers are ready
  • Reduces the dead mat of weeds common after a spring burndown to speed soil warming and dryout, especially in no-till fields
  • Keeps soil moisture available for the young crop
  • Helps create a warmer, drier seedbed for uniform emergence and better seedling vigor
  • Decreases insect pressure by eliminating the conditions insect populations use to become established

When implementing a fall weed control program, it’s critical to find a herbicide solution that offers a thorough spectrum of control on postharvest weeds. A herbicide such as Elevore® uses a systemic approach that works to kill a broad range of weeds from the inside out, including actively growing marestail up to 8 inches tall and other ALS- and glyphosate-resistant species.

The results provide farmers with numerous benefits, including a more streamlined workload with fewer hours of spring work, better-prepared fields at planting and the opportunity for increased yield at harvest.

Education: From the start, a key pillar for Enlist™ weed control system

David Hillger

David Hillger,
Ph.D., herbicide trait field specialist

Retailers understand that successful herbicide application means not just controlling weeds but also taking care when applying near surrounding crops and gardens.

From the beginning, education has been one of the keys to launching the Enlist weed control system. We always realized the importance of committing resources to help users understand this technology and use it correctly. We’re continuing these efforts to reach retailers, applicators and, of course, farmers.

Farmers who’ve applied Enlist herbicides according to the label have controlled their toughest weed challenges and, thanks to Colex-D® technology, seen the value of lower potential for physical drift and near-zero volatility.

Three key pillars of Enlist technology
Stewardship education has been a strong foundation in the development of the Enlist technology. Three important pillars support the Enlist system:

  1. The Enlist trait, which allows farmers to apply Enlist herbicides postemergence on Enlist cotton, corn and soybeans.
  2. Enlist herbicides — Enlist Duo® and Enlist One herbicides — which control tough broadleaf weeds that increasingly challenge farmers. Both feature Colex-D technology to help herbicides stay where they’re sprayed when applied according to the label.
  3. The Enlist Ahead management resource, which is designed to help farmers succeed while promoting the responsible use of the Enlist system.

We developed Enlist Ahead with extensive input from farmers and other key stakeholders. This management resource has been a vital part of our Enlist system since 2012, well before Enlist crops and herbicides were in any farmer’s fields.

Enlist Ahead resources focus on the proactive management of weed resistance, minimizing potential for off-target movement of Enlist herbicides and promoting trait stewardship.

Enlist Ahead training combines in-field training experiences, classroom-style instructor-led sessions and online training. We support training with robust literature and reference materials on Enlist.com, as well as access to our team of in-field experts to help advise about field planning, sprayer setup and application planning.

When I’m visiting with farmers, one of the first things I like to do is understand where they plan to plant their Enlist crops. Together, we’ll look at what crops are in neighboring fields, weed pressure and types of weeds in the field. Then we can tailor a plan using Enlist Ahead resources, including the Enlist Ahead app.

Enlist representatives have worked with and trained tens of thousands of farmers, applicators and retailers at in-field demonstrations across the entire Corn Belt and Cotton Belt.

Retailers can take advantage of many online tools, including the Product Use Guide, sprayer cleanout guide, application guide and the Enlist Ahead detailer, which includes information on the Enlist Ahead app, incentives and other benefits.

Difficult weeds require strong residual herbicides

Chris Pritchett

Chris Pritchett,
Product Manager,
Corteva Agriscience,
Agriculture Division of DowDuPont, Dow AgroSciences

A cold, wet start to spring is making preplant and preemergence herbicide applications challenging to schedule this year. Soybean farmers need to control difficult weeds in a timely manner to preserve yield potential.

Marestail, waterhemp, giant ragweed and Palmer amaranth are among the most difficult weeds to control in many Midwest soybean fields. These weeds have shown resistance to multiple herbicides, including glyphosate. Using multiple modes of action in a timely manner is key for effective control throughout the season.

If your customers still have time to apply a preemergence herbicide, Sonic® herbicide is a valuable tool that offers two nonglyphosate modes of action to provide long-lasting residual control. It’s proven to deliver long-lasting, broad-spectrum control to prevent weeds from invading soybean fields.

If soybeans are already emerging in your area, FirstRate® herbicide is a flexible and economical option for preemergence and postemergence control of broadleaf weeds.

If soybeans are already emerging in your area, FirstRate® herbicide is a flexible and economical option for preemergence and postemergence control of broadleaf weeds. FirstRate can be tank-mixed or applied sequentially with glyphosate to help control common ragweed, lambsquarters and marestail. DuPont EverpreX herbicide also provides a wide application window from preplant to postemergence up to 90 days before harvest. EverpreX helps soybean farmers gain residual control of many weeds and grasses resistant to ALS, PPO and glyphosate.

Three weed control trends to watch in 2018

Kent Bennis

Kent Bennis,
market development specialist, Dow AgroSciences

Weeds are relentless year after year, leading farmers, retailers and agronomists across the Midwest to find new ways to control difficult and herbicide-resistant weeds in corn and soybean fields.

While the weed spectrum hasn’t changed much in recent years, the available methods and level of difficulty to control these weeds has changed. We’re seeing several trends, as part of a sound herbicide program, that are helping farmers improve ROI and counter weed pressure.

To overcome challenging weeds in corn and soybeans, here are three top weed-fighting strategies to keep in mind this season.

1. Invest in multiple herbicide passes
The timing of herbicide passes is shifting. There are instances when farmers prefer to apply a residual herbicide shortly after planting rather than before. Herbicide timing largely depends on the weed spectrum and density. With increasing herbicide resistance, a two-pass program is the best way to keep weeds small throughout the season.

To control weeds early – even ahead of planting – farmers can tank-mix burndown herbicides with residual herbicides to plant into a clean field. Dow AgroSciences recently received federal registration from the U.S. Environmental Protection Agency for Elevore herbicide, powered by Arylex® active, which can be applied up to 14 days before planting in soybeans and corn. Elevore is tank-mix-compatible with commonly used burndown and residual partners, including 2,4-D and glyphosate, for thorough control of many broadleaf weeds, including marestail up to 8 inches tall.

2.  Layer residual herbicides to extend weed control
Farmers should overlap, or layer, residual herbicides to control tough weeds like Palmer amaranth and waterhemp, which germinate throughout the growing season. Farmers can use Resicore® herbicide or SureStart® II herbicide for residual control in corn and Sonic® herbicide or Surveil® herbicide for long-lasting control in soybeans.

3.  Control pigweeds early before they progress across fields
Waterhemp and Palmer amaranth continue to be driver weeds in corn and soybeans. Waterhemp is slowly taking over more acres each year, and if a farmer is in an area where it was just starting to get bad last year, it’s likely getting worse.

In soybeans, farmers can also improve control of tough weeds, including the pigweed species, by planting narrow rows of seven to 15 inches. This allows the crop to shade the row much quicker, which reduces weed germination and emergence.
