Vertisan® Fungicide

Extended Broad-Spectrum Control of Diseases That Hurt Crop Yield and Quality

Growers searching for lasting preventive and postinfection control of damaging potato diseases can improve potato yield and quality by adding DuPont™ Vertisan® fungicide to their potato management programs.

East Idaho Large-Scale Field Trials

Higher yield and higher net profit for Vertisan® (16 fl oz in furrow) followed by Vertisan® (16 fl oz chemigated) vs. adjacent grower standard program (Quadris 8 fl oz in furrow)

Balanced disease management and broad-spectrum control of foliar and soil-borne diseases means Vertisan® delivers strong protection of potatoes and other crops, including canola, sunflower, sugar beets, cereal grains and legume vegetables such as chickpeas, lentils and dried beans. The result is powerful, consistent field performance.

For potatoes, Vertisan® provides:

  • Early season control of black dot, Rhizoctonia, Alternaria early blight, powdery mildew, brown spot, Botrytis, white mold and other diseases
  • Extended disease protection when applied at row closure
  • In-season plant health; vigorous plants make most efficient use of crop nutrients

In canola, use Vertisan® to manage Alternaria blackspot and Sclerotinia stem rot and white mold. In sunflower crops, Vertisan® controls Alternaria leaf spot, powdery mildew, rust, Septoria leaf spot and Sclerotinia stem rot.

(Not for use in these crops in California or New York.)

Vertisan® provides application flexibility and peace of mind due to the unique properties of its SDHI active ingredient and proprietary formulation:

  • Translaminar and locally systemic protection in plant tissue
  • Movement into the root zone; detected 6 inches below the soil surface 4 weeks after application
  • Applied via fast lap (up to 0.25 inch) followed by normal irrigation
  • Rainfast within 1 hour of application

Maximum residue levels (MRLs) for Vertisan® on potatoes have been set for major importing countries.
