Three factors to consider when assessing Plant Health in Corn

The end of the season is the perfect time to check back in with your customers to evaluate what recommendations offered them success in their corn crop, and what still needs to be improved. These important conversations allow you to tailor crop protection plans for next year that will help your customers have a winning season to achieve their targets.

One input that you should evaluate with your customers this offseason is their use of fungicides. For example, did making a fungicide application have a positive impact on their corn yield? Did it provide them peace of mind or improved harvestability? Did the fungicide meet their unique expectations?

When it comes to products like Headline AMP® and Priaxor® Xeminum® brand fungicide, look for disease control in addition to evidence of environmental stress reduction, as these both can lead to improved crop growth efficiency and maximized yield potential.  Together these demonstrate the value of BASF Plant Health. When it comes to evaluating fungicides, yield monitor comparisons across test strips are valuable, but there are many factors you can examine with your customers to determine the impact of a fungicide application, such as disease evaluations, thermal imagery for canopy temperature or harvest efficiency. 

Evaluating Plant Health after adverse weather events

Mother Nature continues to throw curve balls throughout the growing season, but having the confidence to provide proactive recommendations can help your customers prepare for and recover from the worst. Following up post-application is just as important to ensure your customers see the value from those recommendations.

For example, we never know where or when a hailstorm might occur. On June 7, 2018, a hail event occurred near Yuma, Colorado, causing serious damage and flooding to crops in the area, including to a cornfield at the Irrigation Research Foundation. To minimize the impact of that environmental stress, alternating strips of Priaxor Xeminum brand fungicide were applied to the damaged field three days after the hail event occurred.

A month after the application, it was clear the plants that received an application of Priaxor Xeminum brand fungicide were taller and greener than the corn that went untreated after the hailstorm. * By minimizing the impact of the environmental stress event, the application of Priaxor Xeminum brand fungicide allowed the crop to recuperate more quickly following the hail event, enhancing corn growth efficiency. This impact was further documented with NDVI drone imagery, which highlighted the positive impact Priaxor Xeminum brand fungicide had on Plant Health and biomass, maximizing the opportunity for photosynthesis and yield potential.

Leveraging the yield components to illustrate the benefits of Plant Health

When evaluating the yield impact from a fungicide application, it’s important to go back to the basics and evaluate the corn yield components.  Corn yield is derived from multiplying the number of ears per acre, the number of kernels per ear and the test weight of each kernel.

Growers know that they have the most yield potential when they purchase the bag of corn seed. Once planted, however, environment and time are working against them, continually reducing that yield opportunity. It’s important they think back to the corn yield components and maximize plant stand, biomass and grain fill.  Fungicides like Headline AMP and Priaxor Xeminum brand fungicides can be part of the plan to help minimize the impact of both biotic (disease) and abiotic (environmental) stresses to maximize corn growth efficiency and maintain that yield potential growers purchased. 

Keeping fungicides top of mind

Fungicide performance and its impact on crop production efficiency should be evaluated season-long, not just at harvest time. And the fungicide conversation should continue through the planning season to help customers be proactive in achieving their crop production goals. 

In more than 550 on-farm corn trials over the last six years, Headline AMP fungicide delivered a positive yield response more than 92 percent of the time over untreated. * This consistent performance is something you can count on to help you ensure you deliver on your customers’ expectations.

Remember, BASF Plant Health fungicides offer more than just disease control and yield potential.  When you’re out scouting your customers’ corn crops, show them the impacts they achieved with the application of Headline AMP or Priaxor Xeminum brand fungicides. Use various techniques to evaluate and showcase the reduced impact of stress events from foliar diseases or adverse weather. Show them the enhanced disease control, drought tolerance, healthier and greener plants, and improved standability. Help them understand how applying BASF Plant Health fungicides benefited their operational efficiency and their bottom line.

With the growing number of tools we have available to us to evaluate product performance, you can show your customers the impact of their fungicide performance season-long. Keep these examples at hand through the planning process, as your customers rely on your expertise to help them develop a strong, proactive crop protection plan to achieve their crop production goals.
