Application Tips

Boost fungicide effectiveness on spring and winter wheat

Wheat growers know that diseases like Fusarium head blight, also called scab, reduce yields. Scab may also cause an increase in DON (dexoynivalenol) levels, negatively affecting the marketability of the grain. Prosaro® fungicide provides powerful protection from leaf and head diseases, helping to preserve yield and quality.

Use these spring and winter wheat application tips to get the most from your Prosaro application:

ground application sprayGround Application Recommendations

  • With ground applicators, produce a fine-to-medium-sized drop with a flat-fan nozzle.
  • Angle nozzles forward thirty to 45 degrees down from horizontal to increase the concentration of the active ingredient on the head.
  • Apply Prosaro with a carrier volume of at least 10 gallons per acre with nozzles eight to ten inches above the grain heads for best coverage. This helps prevent scab infections and will not compromise control of leaf diseases.

Apply Prosaro during warm, humid weather when conditions are ripe for disease development. In doing so, you reduce the risk of infection and protect the yield and quality potential of your wheat crop. Remember, Prosaro is rainfast within two hours of application or as soon as it is fully dry on the leaf surface.

Under typical disease pressure, the optimum application timing for the best overall performance against both leaf and head diseases is during early flowering. However, it is important to scout your fields for infections caused by diseases like powdery mildew and stripe rust, so you can apply an earlier additional treatment if necessary.
