Plan for a Scab Application and Optimize ROI on Your Fungicide

Planning for a scab application on cereal crop field
Planning for a preventive scab application can help optimize the return on investment (ROI).

Fusarium head blight, or scab, can be one of the most economically damaging diseases in cereal crops. Not only does scab contribute to lower grain fill, the disease is also associated with elevated deoxynivalenol (DON) levels, which can negatively affect the marketability of the grain. When left unmanaged, scab can lead to decreased yields and profit in wheat.

Plan for a Prosaro® fungicide application at Feekes 10.5.1 to help prevent scab

Planning a preventive fungicide application for scab can be beneficial for protecting yield potential and grain quality in wheat. There are three key steps to optimize your return on investment (ROI) and get the most out of your fungicide application.

  1. Choose a fungicide that is effective against scab
    With two very effective active ingredients, Prosaro fungicide from Bayer offers excellent control of scab. Through its outstanding spectrum of disease control, Prosaro fungicide helps improve grain quality and maximize yield potential, increasing your ROI and profit potential. In addition to scab, Prosaro fungicide provides protection against tan spot, Septoria leaf blotch and rust diseases.

  2. Apply at the optimal timing of Feekes 10.5.1
    Applying a fungicide at the optimal growth stage can have a big impact on the level of scab suppression or control achieved. North Dakota State University recommends making a fungicide application at Feekes 10.5.1, or early in the flowering stage to reduce the risks of grain yield and quality losses from scab, as well as other cereal crop diseases.1

  3. Use the full 8.2 oz/A rate
    To maximize efficacy, it is recommended to apply Prosaro fungicide at the 8.2 oz/A rate. Increased efficacy can translate to increased yield potential. In fact, university and Bayer trial data show that spring wheat fields treated with Prosaro at the 8.2 oz/A rate yielded 18 bu/A higher than the untreated check.2

Following these steps will help optimize the ROI of the fungicide application. An optimally timed application of Prosaro fungicide at the 8.2 oz/A rate can help minimize DON levels, which can lead to higher prices at the grain elevator. Plus, by controlling scab and other diseases, Prosaro can help increase yield potential, resulting in more grain fill and more grain to sell.
