ST. LOUIS — When warm conditions, high humidity and high moisture arrive, a perfect storm may be brewing for Fusarium head blight, or scab, to develop and infect cereal crops. Fortunately, an optimally timed fungicide application of Prosaro® fungicide at the 8.2-ounce per acre use rate can help reduce the risk of infection and protect yield potential in small grains.
“The optimal time to apply the fungicide for management of head scab is during that early flowering period, or Feekes 10.5.1,” said Bayer Cereal Expert Kevin Thorsness. “An application at that stage helps protect the florets, which appear first in the middle of the head. This application protects them during the fertilization period and early grain fill.”
An application of Prosaro fungicide at Feekes 10.5.1 not only helps provide disease protection but can also help maximize yield potential in cereal crops.
In fact, in university and Bayer trials, spring wheat fields treated with Prosaro fungicide at 8.2 ounces per acre at Feekes 10.5.1 increased yield by an average of 8 bu/A compared to untreated acres (Figure 1).
In winter wheat trials, a yield increase was also observed. Fields treated with Prosaro fungicide at 8.2 ounces per acre during the Feekes 10.5.1 growth stage demonstrated an average yield increase of 13 bu/A, compared to the untreated check (Figure 2).
“Applying Prosaro at 8.2 ounces at Feekes 10.5.1 will reduce the risk of infection while helping to increase your yield, your quality and your overall profit,” said Thorsness. “Making a fungicide application ahead of the optimal window, or a little bit after the optimal window, is still going to help maximize your yield and improve your grain quality by reducing the amount of disease infection.”
