Herbicide Lessons Lessen Farmers’ Concerns

Growing knowledge about the Enlist weed control system remains vital as Corteva Agriscience, Agriculture Division of DowDuPont, continues to prepare the market for the large-scale commercialization of Enlist E3 soybeans.

Corteva Agriscience will broadly license Enlist E3 soybeans following Chinese import approval of the Enlist E3 soybean trait. Making this trait widely available to farmers requires seamless collaboration with seed companies: The technology must be available in the best genetics over a wide range of maturities. That’s why the company is engaging now with seed companies that plan to add Enlist E3 soybeans to their product lineups.

Ensuring the Enlist technology is in elite soybean (as well as corn and cotton) genetics will help farmers, applicators and retailers who evaluate the Enlist trait be more profitable and successful. 

As this technology gets into the hands of more farmers – and the retailers they trust – it builds comfort with the system and prepares for continued expansion of Enlist crop acreage.

Part of this effort is continued access to education and tools that help users get more out of the Enlist system. Field planning, best management practices, application education and advice help farmers position Enlist crops to perform as promised. This includes on-target application, excellent weed control, exemplary crop tolerance and the opportunity for top yield.

Education from the start
From the beginning, education and product stewardship have been critical pillars of this technology. As a key part of the Enlist weed control system, the Enlist Ahead management resource provides an array of tools to help retailers, farmers, and applicators understand how to use this technology — including Enlist herbicides — appropriately and effectively.

As individual Enlist crops come to market, the emphasis on education, training and stewardship expands. Committing resources to these efforts allows the company to launch these crops in a careful, responsible and measured way.

“When we work with farmers, we emphasize field planning, a program approach and adherence to all label requirements, including downwind buffers,” says Andy Asbury, a field specialist for Illinois. “Farmers are seeing how this system works in their fields.”

Specialists such as Asbury provide tools and training to help ensure farmers can use this technology confidently.

“We can help farmers understand label requirements for our products,” says Steve Snyder, a field specialist who covers the upper Midwest. “In addition, we offer online resources so growers in the field can get quick access to information on their tablets or smartphones.”

Customers are gaining experience with Enlist crops. Enlist Ahead tools provide a wealth of information to help users feel secure when using this much-needed and extremely effective weed control technology. Learn more about the Enlist Ahead management resource by visiting Enlist.com

Maximize your customers’ profit potential with Instinct® and manure

Across the Midwest, manure is becoming an increasingly important fertilizer type for cornfields during spring and fall. To maximize yield, growers invest their time, labor, machinery and fuel costs to apply liquid manure as an effective nitrogen source. And while there’s much to gain, just like with other nitrogen sources, there is also susceptibility to loss through leaching and denitrification.

To extend nitrogen availability in the soil for up to eight weeks, Instinct® nitrogen stabilizer can be easily mixed directly into deep pits and lagoons. This makes nitrogen available and ready when the crop needs it most: during critical growth stages.

How do manure and Instinct® nitrogen stabilizer work together?              

Mixing Instinct into a manure pit and spreading onto fields will extend nitrogen availability for corn and result in overall higher yield. Spreading manure as a fertilizer type is an effective practice and a natural source of nitrogen but may cause leaching and denitrification. Instinct gives farmers the opportunity to increase yield by 10 to 12 bushels per acre* and reduce leaching into groundwater and denitrification by keeping nitrogen at the root zone for a longer period. For maximum crop growth, Instinct provides available nitrogen up to eight weeks longer in key growth stages for corn.

A straightforward approach

When using common agitation procedures, Instinct can be evenly distributed in the entire manure pit and will not cause damage to pit walls due to being alkaline in nature. Once incorporated with the soil, Instinct® nitrogen stabilizer will release the active ingredient, allowing corn to reach its maximum yield potential. Overall, Instinct provides an average revenue increase of $21 per acre,** proving beneficial to add to any farmer’s operation.

Farmers face waterhemp halfway through growing season

While there are dozens of common weeds that threaten yield each season, many Midwest farmers who grow corn or soybeans are facing off with waterhemp now.

This demanding weed is leading the conversation and building strength against herbicides halfway through 2018. It’s crucial to scout diligently, implement a diverse action plan and use a program herbicide approach with multiple modes of action to combat increasingly resistant waterhemp and other common broadleaf weeds.

“New cases of resistant waterhemp are daunting to those of us in the ag industry because it threatens the already-delicate ROI ratio,” says Dave Roome, customer technical specialist, Corteva Agriscience, Agriculture Division of DowDuPont. “But waterhemp can grow stronger each year. We have to stay aggressive at reducing the waterhemp seedbank to protect fall yield and get a head start on next season.”

Roome shares five tips to help farmers manage waterhemp for the remainder of this season and to limit additional resistance development:

  1. Scout diligently. Identify waterhemp early and continue to check your fields now, during midsummer. Ongoing scouting helps farmers plan timely postemergence herbicide applications and identify potential problem fields for the following year. It can be difficult to identify waterhemp in early growth stages because it looks similar to Palmer amaranth and other pigweed species. Waterhemp leaves are generally longer and more lance-shaped than other pigweeds.
  2. Layer residual herbicides. Layering residual herbicides keeps fields clean longer, typically through crop canopy closure, to manage the waterhemp seedbank. In corn, farmers can apply three unique modes of action with SureStart® II herbicide preemergence followed by an additional unique mode of action from Resicore® herbicide early postemergence. In soybeans, Sonic® herbicide provides two modes of action preemergence followed by DuPont EverpreX herbicide for an additional mode of action postemergence. Farmers may also add atrazine to their corn programs and glyphosate to corn and soybean programs, in areas where waterhemp isn’t resistant, to increase the number of different modes of action.
  3. Plant narrower rows. Narrow row spacing can help suppress waterhemp growth by allowing crops to reach canopy closure quicker. Also, tillage is an enemy of waterhemp, Roome says. Tillage can help lower waterhemp populations because the seeds must germinate in the top part of the soil; however, tillage may not be a viable method of control on land prone to erosion.
  4. Prevent weeds from going to seed. Just a few waterhemp weeds left in a field can present significant problems for the next season. Waterhemp that goes to seed in corn or soybean fields can potentially cross-pollinate with a population in another field and build additional resistance.
  5. Maximize application technology. Pay close attention to herbicide labels to maximize the efficacy of the product. Not every herbicide can be applied in the same manner with the same nozzles, water volumes, pressures, and adjuvants. Waterhemp requires herbicide control and effective cultural practices, such as rotating crops, which should be planned for more than a single year at a time, Roome says. When rotating crops, think beyond just rotating corn and soybeans to what you can do in that system. Rotating crops also allows farmers to rotate modes of action and adjust tilling plans for corn and soybean fields.

Learn what’s happening in the field via Experiencing Enlist

Farmers across the country are seeing firsthand the benefits of the Enlist weed control system. They’re managing herbicide-resistant weeds that have been a challenge in recent years.

In the South, farmers are growing PhytoGen® cottonseed with the Enlist trait, as well as raising Enlist E3 soybeans for seed production. In the Midwest, farmers also are raising Enlist E3 soybeans for seed production or in a closed-loop system as part of a collaboration between Corteva Agriscience, Agriculture Division of DowDuPont, and ADM. This year also marks the first year that Enlist corn is commercially available.

Learn from farmers and industry experts as they report on how Enlist crops are performing in on-farm settings across the Corn Belt and Cotton Belt. This year, more participants are sharing their stories and providing information that can help you understand the benefits and work with customers to get the most of the Enlist technology, including Enlist herbicides.

Here’s a sampling from Experiencing Enlist:

“Enlist One herbicide allowed us to tank-mix a residual to provide better control of waterhemp,” says Shane Baxter, a Missouri farmer growing Enlist E3 soybeans for seed production.

“The control Enlist Duo provided was phenomenal,” says Luke Liechty, an Indiana farmer who also is growing Enlist E3 soybeans. “I didn’t see drift or volatility when applying Enlist Duo.”

“You always want multiple modes of action in a field every year,” says Steve Snyder, herbicide trait field specialist. “I suggest three to four modes of action per crop per year.”

Late corn planting? Stay focused on weed control

On Groundhog Day in February 2018, Punxsutawney Phil saw his shadow, signaling six more weeks of winter. Months later, farmers are feeling the impact of that prediction as prolonged cool weather delayed corn planting across the Midwest. Farmers are making quick progress to remedy the delay, but unfortunately, so are weeds. 

If any weed grows more than a few inches tall, it is difficult to control. Some common weeds, such as marestail, can grow almost any time of the year without being dormant long. Other weeds, such as waterhemp, can grow 1.5 inches per day. It’s critical to scout for these weeds throughout the growing season so you can identify them early and implement an effective herbicide program.

Because of heavy pressure from Palmer amaranth and kochia, Nebraska farmer Blake Johnson sees the importance of early season weed control despite a later start to planting. Johnson usually begins planting corn around April 10, but at that time this year he had just applied a burndown herbicide.

“We’re incorporating Resicore as the corn emerges for good blanket of residual to get the crop to canopy,” Johnson says. “With our corn program, we want to use different modes of action. We’ve always used dicamba in our post application but now we’re using Resicore, which doesn’t have dicamba, to get a different mode of action.”

Recommend herbicides that are proven to perform.
There are a variety of unique corn herbicides to help your customers control weeds pre- and postemergence, including:

  • Resicore® herbicide gives farmers power over weeds deep into the growing season. Introduced to cornfields in 2016, Resicore brings together three modes of action and a wide rate range to fit a variety of agronomic programs, including preemergence, postemergence or split applications.
  • SureStart® II herbicide is proven to give corn a strong start as the first pass to control difficult and herbicide-resistant weeds and grasses. SureStart II can be applied preplant or on up to 11-inch-tall corn, giving your customers the flexibility to overcome unexpected weather delays and cover more ground.
  • DuPont Realm® Q herbicide provides excellent postemergence broadleaf weed control in corn, with a built-in crop safener and multiple modes of action. The convenient dry formulation of Realm Q makes measuring, mixing and cleanup easier, and it eliminates the need for pumps, tanks or meters.
  • DuPont Cinch® ATZ herbicide and Keystone® NXT herbicide are dependable solutions for your customers wanting to apply a residual with atrazine. Both products can be applied from preplant through early postemergence.

In 2017, Nebraska farmer Blake Johnson applied FulTime® NXT herbicide preemergence followed by Resicore® herbicide postemergence to keep his cornfields clean deep into the growing season.

Follow checklist to keep Enlist™ herbicides on target

Help your customers keep herbicide applications on the intended target to ensure better weed control results. For crispy weeds and clean fields, use the tips below to apply Enlist One herbicide or Enlist Duo® herbicide to Enlist corn, cotton or soybeans.

Application window: Ensure your crops are within the right growth stage window for an application of an Enlist herbicide.

Tank-mix partners: Before adding any other products to the sprayer, check EnlistTankMix.com for qualified tank-mix partners for each Enlist herbicide.

Nozzles: Use only nozzles and pressure combinations listed on the labels for Enlist One herbicide and Enlist Duo herbicide.

Wind speed and direction: The wind speed should be between 3 and 10 mph when making an application. Do not apply during a temperature inversion.

Susceptible crops: Make sure the wind is blowing away from susceptible crops. There is not an acceptable buffer for an application of an Enlist herbicide if the wind is moving in the direction of susceptible crops, such as cotton without the Enlist trait.

Sensitive areas: Leave a 30-foot downwind buffer to sensitive areas, such as woods, pastures, grass ditches and lawns.

Sprayer contamination: To avoid sprayer contamination, clean the sprayer out thoroughly before making an application. Pay attention to screens, nozzles and hoses and make sure they are cleaned, as well.

For on-target herbicide application and efficient weed control, use only nozzles and spray pressure settings listed on the herbicide label.

Spray pressure: Apply Enlist One herbicide and Enlist Duo herbicide at the right pressure based on the label and current environmental conditions.

Spray rate: Check that you are applying Enlist One herbicide at 2 pints per acre or Enlist Duo herbicide at 4.75 pints per acre.

Spray volume: For best results, use a spray volume of 10 to 15 gallons of water per acre.

Boom height: Consult the nozzle manufacturer for optimum boom height when applying Enlist herbicides.

Cleanout: Fill at least 10 percent of the tank volume with clean water and flush the sprayer. Be sure to triple-rinse the sprayer when you complete an application of an Enlist herbicide.
