Fungicide application timing will make or break corn yield

June 22, 2016

The success of this season’s corn yield could be contingent on whether or not growers choose to apply a fungicide at the R1 stage of development.

Corn at the R1 stage is fully tasseled and beginning to green silk. The largest yield reduction occurs during this stage when corn is under stress. Applying a fungicide at this time can do more than just control disease; it can also help corn to:

  • Use water more efficiently
  • Preserve soil moisture
  • Improve CO2 assimilation and nitrogen utilization
  • Extend the pollination window

Applying fungicide at the R1 stage will provide better disease control, protect stalk integrity, improve harvest efficiency and reduce volunteer corn in the crop to follow, each providing significant value to the grower’s bottom line.

UTC-Priaxor-Trivapro

One pass of Trivapro works harder than a two pass of Priaxor® and Headline AMP®.

For protection against disease and impacts of environmental stress at R1, Syngenta recommends using Trivapro® fungicide. Trivapro combines triazole, strobilurin and a SDHI component: Solatenol®. Trials have shown it has the longest residual control available on the market, and is both a preventive and curative option for disease.

When applied during tassel/R1, Trivapro can increase corn yield by an average of 25 to 53 bushels per acre.[1] Applying a proven fungicide to corn at this crucial stage in development can improve yield potential and increase growers’ overall return on investment this season.
