Maximize Above-ground Nitrogen Applications With New PinnitMax™ Nitrogen Stabilizer

By: Tina Troester, nitrogen management specialist, Corteva Agriscience™, Agriculture Division of DowDuPont  

As farmers reflect on this past growing season and make plans for spring, nutrient management is a large part of the equation. Nitrogen stabilizers are an important component of nutrient management plans, and Corteva Agriscience, Agriculture Division of DowDuPont, has announced a new nitrogen stabilizer that fills an industry need and adds to its nitrogen maximizer portfolio.

PinnitMax addresses a need for better handling with above-ground nitrogen stabilizers by providing a user-friendly urease inhibitor that maximizes application of urea and UAN. This solution from Corteva Agriscience adds to the nitrogen maximizer portfolio, which currently includes N-Serve and Instinct below-ground nitrogen stabilizers. Now, farmers and retailers can select from our comprehensive protection of any nitrogen source above- and below-ground.

PinnitMax specifically prevents volatilization of urea and UAN applications for up to 14 days, ensuring nitrogen gets into the root zone for optimum crop uptake. The unique formulation of PinnitMax also allows for simple blending, free-flowing applications and effortless cleanup — freeing up labor and processing time for a more efficient operation. In addition, PinnitMax contains an exclusive composition of the active ingredient, NBPT. This composition makes PinnitMax™ the most powerful, gallon-for-gallon, above-ground nitrogen stabilizer with an ultra-low use rate.

PinnitMax completes the existing nitrogen maximizers portfolio from Corteva Agriscience by providing above-ground nitrogen protection in addition to the two below-ground nitrogen stabilizers, N-Serve and Instinct. All fertilizer types can be protected with this portfolio: PinnitMax for above-ground urea and UAN applications, N-Serve for below-ground anhydrous ammonia applications and Instinct for below-ground urea, UAN and manure applications. PinnitMax works above ground to help your nitrogen get to the root zone. N-Serve and Instinct technology work below ground to keep it there.

Best of all, the portfolio has more than 40 years of experience shaping the nitrogen stabilizer category along with the most extensive university research available, providing the proof of efficacy that so many farmers and retailers look for and expect.

Enlist™ Cotton Successes Set the Stage for Future Use of Enlist E3™ Soybeans

By David Hillger, Ph.D., Field Specialist

The Enlist weed control system has continued to prove its worth in 2018. Cotton farmers lead the way, adopting the technology successfully on a wide scale throughout the Cotton Belt.

As we prepare for the third full commercial year of the Enlist system in cotton, that launch can provide a preview of what to expect when Enlist E3 soybeans are fully commercialized. In 2018, cotton farmers planted 1.5 million acres of PhytoGen W3FE cottonseed, which includes the Enlist trait. Rapid growth means more than 70 percent of the PhytoGen upland portfolio was Enlist cotton this year, and Enlist cotton acres tripled vs. 2017.

The Enlist team working in the Corn Belt learns from our counterparts in the South, who have been advising retailers, applicators and growers throughout these couple of years. We can use their experiences and help retailers prepare their customers to succeed with Enlist E3 soybeans, once we fully commercialize them.

Like Enlist E3 soybeans, Enlist cotton features three herbicide tolerances – 2,4-D choline, glyphosate and glufosinate. Cotton growers are using Enlist One and Enlist Duo herbicides as cornerstones of a program approach. Growers who implement weed control programs delivering multiple modes of action not only obtain better weed control during the growing season but also help curb the development of resistant weeds in future years.

As we look forward to full commercialization of Enlist E3 soybeans, consider these key learnings from cotton country:

  1. Help customers make a plan when incorporating a new trait technology. Urge them to use the Enlist weed control system on areas with glyphosate-resistant weeds. Consider the surrounding landscape and nearby susceptible crops.
  2. Develop and follow a weed resistance management plan. This involves using multiple herbicide modes of action to curb the development of resistant weeds.
  3. Follow the label when applying Enlist herbicides. These products offer inherent low volatility and a better formulation for drift reduction. However, applicators must always follow all label requirements. It’s critical that they pay attention to wind speed and direction, equipment cleanout and environmental conditions. Those who have used the system tell us when they follow the label, they have success in the field.
  4. Fully use all trait tolerances. If your farmers like glufosinate-tolerant soybeans, Enlist E3 soybeans are a natural next step with added herbicide tolerances. Farmers can tank-mix Enlist One herbicide with glufosinate or take advantage of the convenient blend of Enlist Duo herbicide to apply 2,4-D choline and glyphosate easily.
  5. Complete training before it’s time to spray. Retailers, applicators and farmers should take advantage of education and training opportunities before using the Enlist weed control system. Retailers can complete Enlist 360 training online for an overview of the system. They can send their customers to Enlist.com to learn more, too.

Retailers can help their customers evaluate new technology options if they understand those options themselves. We urge retailers to take advantage of the Enlist 360 training, found at Enlist.com. The Enlist weed control system truly is different from traditional 2,4-D and other herbicide trait systems.

We look forward to full commercialization of Enlist E3 soybeans in the future. We’re focused on preparing the industry to succeed with these elite soybean varieties containing the Enlist trait. As we continue to increase Enlist E3 soybean production and expand genetic lines, we’re committed to educating and training users how to incorporate the system confidently and successfully on their farms.

A clean spring starts with a preemergence herbicide

As your customers evaluate this season’s yield and adjust their weed control plans for next season, reinforce the value of a preemergence herbicide with them for a clean start. By relying only on postemergence applications, waterhemp, marestail and other common weeds can start robbing corn and soybean yield right after planting.

Spring is a vulnerable time for crops as they require a strong start to thrive for the rest of the season. In an April poll on OperationCleanFields.com, most retailers — 58 percent — selected waterhemp as their customers’ most challenging weed followed by marestail at 23 percent.

Marestail is generally considered the most difficult weed to control if it can overwinter into the spring. When this happens, marestail grows rapidly as temperatures warm, robbing soil of two critical inputs: moisture and nitrogen. Since marestail can germinate throughout the entire year, it’s important for retailers and farmers to scout for it year-round and identify it early in the rosette stage for effective control.

The photos below were taken in McLean, Nebraska, on July 9, 2018. McLean is in the Northeast part of the state and where marestail is one of the biggest weed challenges. The fields shown received spring applications of Sonic® herbicide in soybeans and Resicore® herbicide in corn to allow the crops to grow with less weed competition.

“To reduce the spread of resistant weed populations, such as marestail and waterhemp, farmers should plan their herbicide control and crop rotation for more than a single year at a time,” says Dave Roome, customer technical specialist, Corteva Agriscience, Agriculture Division of DowDuPont. “The most important tip for farmers fighting these weeds in their corn or soybean fields is to act early by starting with a preemergence herbicide to keep weeds small and easier to control.”

Talk with your Corteva Agriscience territory manager about how you can help your customers get a jump on weeds in corn and soybean fields next spring. For more information about Resicore and Sonic, visit PowerOverWeeds.com and BattleWeeds.com, respectively.

Weed of the Month: Giant Ragweed

  • giant ragweedCommon name: Giant ragweed
  • Scientific name: Ambrosia trifida1
  • Grass or broadleaf: Annual broadleaf
  • Giant ragweed grows in the Midwest and Eastern regions of the United States, but it is most heavily concentrated in the eastern Corn Belt states like Indiana and Illinois.2
  • Germination timing: Giant ragweed is traditionally an early season weed; however, its growing season is expanding. Giant ragweed typically sprouts in early May but has been seen as early as March. The weed can continue to cause issues through late July and can impede harvest if not controlled.2
  • Competitiveness: Giant ragweed is one of the most competitive weeds in corn and soybeans.
    • Two giant ragweed plants within a 110 square feet area can reduce corn yield by 13 percent.2
    • Soybean yield can be reduced by 50 percent when there is just one giant ragweed plant within a 110 square foot area.2
  • Giant ragweed can grow 1-5 feet taller than competing plants and can reach heights of up to 17 feet tall.2

Fast facts

  • When a giant ragweed plant first emerges, it can be identified by its spatulate cotyledons. These cotyledons are spoon-shaped and can range from 1 to 1 ¾ inches long.2
  • Giant ragweed always has three distinct lobes but can show up to five lobes that grow in an opposite arrangement.2
  • According to WeedScience.org, the first confirmation of herbicide resistant giant ragweed in the United States was in an Indiana soybean field in 1998.
  • Giant ragweed is a monoecious plant, which means that separate male and female flowers can found on a single plant.2
  • Giant ragweed seeds can be identified by their points and ridges that make them look like small crowns.2

Weed management tips2

  • Use multiple modes of action:
    • One of the best ways to fight giant ragweed is to use multiple modes of action in a herbicide program with both preemergence and postemergence herbicides.
  • Scout for weeds:
    • Look for giant ragweed two weeks after the postemergence herbicide application and determine if another application is needed.

Resistance Statistics*

  • According to to WeedScience.org, herbicide-resistant giant ragweed has been documented in corn and soybean fields in 13 states: Arkansas, Illinois, Indiana, Iowa, Kansas, Kentucky, Minnesota, Mississippi, Missouri, Nebraska, Ohio, Tennessee and Wisconsin.*

*Resistance confirmation does not include all weeds and may vary among different areas of each state.
