The best 2020 nutrient management plan is one that is planned now

By: Ron Geis, Market Development Specialist, Iowa, Corteva Agriscience       

Nitrogen is one of the single biggest expenses for farmers, and a lot of times, we hope that mother nature helps in keeping it where it should be. Relying on nature to take good care of your nitrogen is risky, but the good news is a smart nutrient management plan can help mitigate some of that risk.

Nutrient management, and nutrient success, requires preplanning and a good understanding of how corn takes up nitrogen, what the soil in your area requires and what’s needed to increase yield. Taking the time to help your customers preplan their nutrient management now can really make a difference in how their fields and yield looks by this time next year.

How to plan for 2020 nutrient needs
When building your 2020 nutrient management plan, it’s important to first consider the entire system and look at factors like soil type, weather patterns, past yield history and previous application rates and combinations. This will help identify how much nitrogen will be needed to raise a bushel of corn in the coming season and what actions need to occur throughout the year to achieve this.

Beyond a depth of knowledge of the operation location and conditions, there are other tools to help uncover nutrient needs so a solid nutrient management plan can be built accordingly.

  • Digital tools
    Drone and imagery scouting has grown in popularity and has proven to be a helpful tool in providing a complete look at your customers’ fields. These tools help map problem areas that need some nutrient TLC and can help around harvest as we begin planning nutrient needs for next year. Drones and imagery can also be used next spring and summer to help calculate where nutrient corrections need to happen in-season.
  • Variable applications
    Beside the great digital tools that allow us to see deficiencies early enough to take action, nutrient management plans should include the practice of variable applications of nutrients and occasionally crop protection products. This helps maximize the efficiency of your applied nutrients by going to the soil when crops need it most and protects against overapplying nutrition.
  • Nitrogen stabilizers
    Nitrogen stabilizers, such as N-Serve® and Instinct®, are an important component to a nutrient management plan because they help provide a sense of insurance to applied nitrogen. They extend the availability of nitrogen in the soil so it’s there during critical growth phases. Additionally, nitrogen stabilizers protect nitrogen from leaching and denitrification, so your nitrogen will be less vulnerable to loss in variable weather conditions.

Where to start? What can be done now?
From now through harvest, retailers should focus on fall nitrogen applications and get a head start mapping out nutrient needs and methods of protecting nitrogen with their customers. Retailers should talk with hog producers and manure applicators about applying Instinct directly to their pits. They should also talk to fall anhydrous ammonia users about stabilizing with N-Serve.

When it comes to fall nitrogen application, it’s best to wait for cooler temperatures and refrain from applying too early so you don’t lose valuable nitrogen. The ideal application range is at 50 F and falling. Nitrate conversion stops around 40 F, which typically in the Midwest is around late November. By using a nitrogen stabilizer with fall applications, you will have that nitrogen protected through the heavy rain periods in April and May. And, really, this is the best way to begin your 2020 nutrient management plan.

In summary, good nutrient management not only helps with yield and can be a differentiating margin opportunity for you but also is helpful to your customers’ investments, bottom line and the environment.

Licensees Signing on to Provide Enlist E3™ Soybeans, Widening 2020 Availability

By: Shawna Hubbard, herbicides product manager       

Shawna HubbardCorteva Agriscience is working with more than 100 independent seed companies to broadly license the Enlist E3 soybean trait. These efforts will enable wide availability for 2020 and beyond, making Enlist E3 soybeans available to growers who need advanced weed control solutions.

The goal of bringing the benefits of Enlist E3 soybeans to growers in their preferred brands was established years ago, as early commercialization plans were drafted for the Enlist system. Corteva Agriscience is proud to work with seed companies to make Enlist E3 soybeans available to their customers. Enlist E3 soybeans fit across a wide range of geographies and maturities, helping growers everywhere achieve excellent weed control and strong yield.

We project that Enlist E3 soybeans will be planted on at least 10% of U.S. soybean acres in 2020. Farmers can visit Enlist.com for a list of seed companies who are offering Enlist E3 soybeans for the 2020 season. Enlist E3 soybeans also are available from Corteva Agriscience brands: Pioneer®, Mycogen Seeds, AgVenture, Dairyland Seed, Hoegemeyer Hybrids, NuTech Seed®, Seed Consultants and Terral Seed.

Offering exceptional weed control
The introduction of the Enlist E3 soybean trait into these seed company lineups will give an effective weed control option to soybean farmers from North Dakota to Texas and from Colorado to the Carolinas. Farmers who plant Enlist E3 soybeans can take advantage of Enlist herbicides to help manage tough and resistant weeds. When used in a program approach that includes a burndown application and preemergent applications of effective residual herbicides, Enlist herbicides will help growers keep weeds under control throughout the growing season.

Starting clean and applying preemergence residual herbicides sets the stage for applications of Enlist herbicides postemergence on Enlist E3 soybeans. Enlist Duo® herbicide is a combination of 2,4-D choline and glyphosate to control broadleaf weeds and grasses. Enlist One® herbicide is a straight-goods 2,4-D choline that offers additional tank-mix flexibility with other products such as glufosinate.

With the ability to use 2,4-D choline, glyphosate and glufosinate postemergence, soybean farmers can employ multiple modes of action against their most difficult weeds. Using multiple modes of action also retards the development of herbicide-resistant weeds.

Expanding flexible options
Making the Enlist weed control system broadly available through many seed organizations will give soybean farmers the opportunity to control tough and resistant weeds by using multiple herbicide modes of action.

Retailers can learn more about the Enlist weed control system and the companies producing Enlist E3 soybeans by visiting Enlist.com, following @EnlistOnline on Twitter or going to the Enlist  YouTube channel.

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.
