Plan to Optimize Sidedress This Season

By: Danny Leckie, U.S. Product Manager, Soil Health, Corteva Agriscience

3 Key Takeaways from This Article:

  • Sidedress applications for nitrogen are a great way to ensure proper nutrition for corn.
  • Test your customer’s soil when the corn is about 6 to 12 inches high.
  • Apply sidedress prior to V9.

We know the world has changed rapidly over the last few months and that your way of doing business has likely changed as a result. Our hope is that Inputs & Insights can continue to serve as a guide for you to help your customers as everyone navigates the challenges ahead.

Depending on what this spring has been like in your area, you may have decided sidedress fertilizer applications will be needed for your customers. Sidedress applications are often necessary if the weather is not cooperative for a preplant spring fertilizer application.

For example: If there is too much rain, or if the soil is too wet, nitrogen will be vulnerable to leaching if applied. In addition, your growers may simply prefer a split application: applying some of their nitrogen preplant and then again during sidedress, which is typically around the late May to early June time frame.

When done correctly, sidedress can help ensure proper nutrition for corn precisely when the plants need it most.

The process is also recommended as part of  The Fertilizer Institute’s 4R Nutrient Stewardship program.

First: Test the Soil
A pre-sidedress soil test is essential to make sure you apply only the necessary nitrogen to the corn crop.

Here are some good rules of thumb to follow:

  • Test when corn is 6 to 12 inches tall (typically late May to early June).
  • Sample areas that are similar in texture and 10 to 20 acres in size.
  • Avoid sampling from previous fertilizer application bands.
  • Tests should consist of 15 to 20 cores per sample.

Second: Apply at the Right Time, the Right Way
UAN, urea and anhydrous ammonia are all great options for sidedress fertilizer. That’s because they’re easily accessible to the plant after application. You’ll want to perform applications prior to V9 to ensure the best uptake for corn. Applying from V4 to V6 is ideal.

Anhydrous ammonia can be easily lost if soil conditions aren’t right or the application isn’t precise. So, when knifing anhydrous into the soil, make sure to fully close the openings to keep it from escaping. Make sure soil is not damp or clumpy when applying anhydrous.

Last: Protect Sidedress Nitrogen
Last, but certainly not least: It’s advisable to protect sidedress fertilizer applications with a nitrogen stabilizer. Urea, UAN and anhydrous ammonia are all immediately vulnerable to loss through leaching and denitrification. Instinct® nitrogen stabilizer will protect urea and UAN. N‑Serve® nitrogen stabilizer will protect anhydrous ammonia.

Stop the Clock on Crop Disease This Season

3 Key Takeaways from This Article:

  • We could see a wetter-than-average spring this year.
  • Many crop diseases thrive in wet, humid weather.
  • You’ll want to recommend your customers use a fungicide this season.

We could be in for another rainy spring across the Corn Belt. In fact, AgPro Daily has predicted 23 states are at risk for flooding. Many crop diseases thrive in wet, humid conditions. So, with wetter-than-average weather predicted, disease will be a big concern throughout the growing season.

You’ll want to recommend your customers use an effective fungicide to stop those diseases before they damage yield. Corteva Agriscience has a great choice: DuPont Aproach® Prima fungicide.

Moves Fast
Aproach Prima combines two, powerful active ingredients to provide preventive and curative action. The fungicide shows almost 40% uptake in plants within 24 hours and 80% uptake by Day 7. It’s also rainfast within an hour and gives up to three weeks of protection.

Aproach Prima also has four, varying movement properties, which provide complete, systemic protection of plants. Systemic protection means the fungicide moves through the entire plant, surrounding each leaf and stem, including those that are newly emerging.

Convenient Choice
If your customers grow more than one crop, then Aproach Prima is a great choice, because it’s registered by the U.S. Environmental Protection Agency for use in corn, soybeans, wheat and peanuts. Farmers will appreciate the convenience of having one product to protect several crops.

Finally, Aproach Prima is shown to improve crop quality and increase yield. Using the product can help create a better bottom line for your customers.

More wet weather this season means more opportunities for crop disease to hurt yield. Cut those opportunities short and stop the clock on crop disease. Visit AproachPrima.Corteva.us to download the product label and talk to your growers about using a fungicide proactively this year.

Deliver Farmers the Rewards of a Program Approach

3 Key Takeaways from This Article:

  • A program approach with residual herbicides is considered a best practice for successful weed control in soybeans.
  • The benefits include enhanced weed control, more flexible application windows and better field management.
  • Now, with Enlist Ahead Farmer Rewards, farmers also can earn up to $2.50* per acre when adding residual herbicides.

When you’re able to recommend a weed control program in soybeans that benefits both a farmer’s land and bottom line, it’s a win-win. This spring, by recommending a program approach using residual herbicides, your customers can control their toughest weeds and earn valuable cash back when using Enlist Ahead Farmer Rewards.

It starts with taking a program approach to weed control. That means:

  1. Starting clean with a burndown application
  2. Using effective preemergence herbicides with residual activity
  3. Applying Enlist herbicides postemergence

Three easy steps add up to significant benefits for farmers.

According to Aaron Smith, U.S. Product Manager, Soybean Herbicides, “When farmers apply residual herbicides as part of a program approach, they experience benefits like enhanced in-season weed control and more flexible application windows, and it helps them be better field managers. With weeds under control from preplant and well into the season, it ultimately delivers better productivity and increased yield potential.”

Cleaner fields and cash back with Enlist Ahead Rewards
Now, farmers can combine those benefits with the ability to earn cash back on their crop protection needs. With Enlist Ahead Farmer Rewards, customers can now earn up to $2.50* per acre when taking a program approach.

“Enlist Ahead Farmer Rewards is straightforward for farmers and gives retailers better opportunity to improve their customers’ yield potential at harvest,” Smith says. “By participating, farmers can earn significant cash back when they use residuals such as Sonic, Trivence or EverpreX herbicides to keep Enlist E3 soybean fields clean throughout the growing season.”

Much like taking a program approach, the Enlist Ahead program involves three simple steps:

  1. Farmers purchase Enlist One® or Enlist Duo® herbicide. Each contains 2,4-D choline, and they are the only 2,4-D herbicides labeled for use with Enlist E3 soybeans.
  2. Farmers purchase one or more eligible Corteva Agriscience™ soybean residual herbicides, such as Sonic®, DuPont™ Trivence®, DuPont™ EverpreX® or Surveil®, from an authorized retailer from Oct. 1, 2019, to Sept. 30, 2020.
  3. Farmers get an Enlist Ahead Rewards check mailed to them.

Qualifying residual products include DuPont Afforia®, DuPont Canopy®, Elevore® with Arylex® active, EverpreX, DuPont Enlite®, DuPont Envive®, Sonic, Surveil and Trivence herbicides. Farmers can choose Enlist Duo, a convenient proprietary blend of 2,4-D choline and glyphosate, or Enlist One, a straight-goods 2,4-D choline herbicide.

Clean Sprayer Equipment Thoroughly Between Herbicides, Keep Customers Happy

3 Key Takeaways from This Article:

  • Clean all sprayer equipment before entering a field of Enlist E3 soybeans.
  • Clean all the equipment again after spraying an Enlist herbicide. Use a triple rinse and clean as soon as possible after spraying.
  • Make sure to clean all parts and components that come in contact with a herbicide: Think beyond the tank.

We often hear farmers and applicators talk about tank cleanout. But herbicides come into contact with many parts of the sprayer and transfer equipment, so applicators should clean the entire spraying system to prevent potential damage to the next crop.

“Follow label directions for a good, clean start,” says Dan Puck, Enlist field specialist. “As we come into the field, we want to make sure all our equipment is clean and we aren’t carrying any residual traces of herbicide on that equipment.”

For example, Puck says, make sure you don’t have corn herbicides or dicamba contamination if you’re entering a field of Enlist E3 soybeans.

“When you’re done spraying an Enlist herbicide, it’s time to clean out your equipment again before moving into another field,” Puck says. “It’s better to clean your equipment as soon as possible after spraying. It’s a best practice not to let your equipment sit overnight with herbicide residues in the system.”

Enlist herbicides require a triple-rinse process, a common sprayer tank cleanout practice. If you use a tank cleaner, use it during the second rinse step.

But don’t stop at the tank. Be sure to clean all the parts the herbicide reaches.

“You want to make sure you get all the parts and components of the system,” Puck says. “That includes things like your pumps, filters, screens, nozzles, booms and the boom ends. Make sure the entire system is cleaned out.”

Puck says cleanout applies to any other equipment that comes in contact with herbicides such as a tender tank and transfer equipment.

“Specific directions are on the label and in the Enlist product use guide,” Puck says. “It’s a good idea to review them until you’re thoroughly familiar with and comfortable with the appropriate cleanout process.”

Weed of the Month: Kochia

kochiaKochia is a summer annual weed that is showing resistance to different herbicides in several states. The plant thrives in hot weather. So, a program approach featuring residual herbicides and several modes of action is key to controlling the weed throughout the growing season.

  • Common names: Kochia, Mexican fireweed, mirabel, mock cypress
  • Scientific name: Bassia scoparia
  • Cotyledons: Linear to narrowly lance-shaped
  • Leaf shape: Flat, linear to lance-shaped
  • Reproduction: Seed
  • Flowers: Clusters of green flowers with spiked heads

Fast facts

  • Kochia plants can resemble the shape of a Christmas tree.
  • The somewhat bushy weed can grow upward of 7 feet tall, with an extensive root system.
  • Young kochia plants may be confused with lambsquarters seedlings. Kochia has highly branched growth patterns with hairs occurring along leaf margins.
  • The weed germinates in the summer months, annually.
  • Kochia seed production is moderate to high. Seeds disperse via a “tumbleweed” mechanism, meaning a mature stem will detach from its base and then be blown about by wind.
  • Seeds are short-lived in the soil, but they possess a high initial germination rate.

Control tips

  • Corn and soybean growers should start spring with tillage or a burndown herbicide application. Experts advise applying the burndown shortly after the first flush of kochia has emerged.
    • Do not apply the burndown and preemergence herbicide in the same application. Kochia can grow larger and farmers may not achieve effective control.
  • With kochia showing resistance to ALS, glyphosate and triazine herbicides, it’s imperative to use a program approach to control the weed. Layer residual herbicides with multiple modes of action.
    • For example, to control kochia in a soybean field, you could apply Elevore® herbicide as a burndown, then Sonic® herbicide as a preemergent and DuPont EverpreX® herbicide as a postemergent.
  • Kochia thrives in hot weather, so it’s imperative to have residual control throughout the growing season.
