Fungicide plays an incremental role in enhancing late season plant health and maximizing yields in your fields. The Crystal Decisions team is in its fifth year of testing different fungicides on different hybrids across our service area to better assist growers in making the best decisions possible around fungicide. In addition, our team is working to collect drone images and NDVI to evaluate plant health response along with final yield differences at the end of the year.

View examples of our work, including our Farmamerica 2017 corn plot and 2018 study of fungicide response by corn hybrid.

Proper use of fungicide can have a strong impact on late season plant health not only by stopping corn disease at tassel time but also by maintaining stalk quality and strength. According to Tamra Jackson-Ziems, plant pathologist at the University of Nebraska, “That’s because diseased corn leaves can’t produce enough sugars through photosynthesis to fill the ear, so the plant draws carbohydrates from the stalk to feed the ear, weakening stalk integrity. Weak stalks are more likely to snap off or lodge, hindering harvest” (Crop Science).

In addition to the data that our team uses to help our customers enhance their yields, there are some key considerations you can make when prioritizing which fields are in the greatest needs of fungicide applications. These include:

  • Disease severity and potential
  • Hybrid susceptibility
  • Minimum tillage
  • Weather conditions
  • Disease history
  • Other high-risk factors (i.e. continuous corn)

As we continue to increase production and push the yield limits, in-season applications of products like fungicide will play a crucial role. Our Crystal Decisions team is committed to conducting countless tests to gain practical, relevant data that can have a direct impact on your operation.
