Prosaro XTR

Protect your cereals and your bottom line with Prosaro® XTR fungicide. Every season your cereal crop faces many abiotic environmental stresses along with disease pressure that affect both growth and yield potential. With the addition of mefenpyr-diethyl, your cereal crop has a greater ability to mitigate the effects from these stresses, resulting in a healthier, more productive cereal crop.

    For suppression of fusarium head blight, apply as a preventative spray within the time period from when at least 75% of the heads on the main stem are fully emerged to when 50% of the heads on the main stem are in flower. Application at this timing will also control the listed leaf diseases.

    If planning on applying one fungicide application per year and flag leaf disease levels are low to moderate Bayer recommends waiting to apply a fungicide at head timing, protecting against various head diseases including FHB, leaf diseases and subsequently maximizing both quality and quantity of your yield.
    Remember an application at head timing can supply both flag leaf protection and the added benefit of head protection throughout the grain fill period.

Do not use or store in or around the home. Keep in original container during storage.


    It is in everyone’s best interest to preserve the fungicide tools we currently have available to avoid the situation we have with herbicide resistance. It should be noted that there are fundamental differences between herbicide resistance and fungicide resistance. The following three factors need to be considered when assessing if a field is at risk for developing resistance. Assessing your resistance risk includes evaluating the combination of the fungicide mode of action (MOA), the pathogen and the specific farming practices being used.
    Evaluating the Risk of Fungicide Resistance
    Reports of fungicide resistance in cereal crops are fairly rare in North America. The main pathogens of concern for Canadian growers are all classified as low risk, including such diseases as fusarium and rusts. Additionally, agronomic and environmental conditions, which strongly influence resistance risk in Canadian provinces, are regarded as low.
