Curb Severity of Head Scab

Excessive rain and warm temperatures in several areas caused severe cases of Fusarium head blight (scab) to develop last season. Some areas experienced consecutive days of rain just before flowering, making the already narrow fungicide application window even smaller. As a result, many growers saw decreased yield and increased Deoxynivalenol (DON) from head scab infections.

University experts and reports provided to the U.S. Wheat and Barley Scab Initiative (USWBSI) show how the Midwest was affected by head scab last season. Head scab severity in MN was up compared to the previous year. Because of head scab infections, the average wheat yield of 59 bu/A was down from 2017’s record level of 65 bu/A. Southern and southeastern WI also saw reduced yield due to severe cases of head scab.

Imagine what it would be like, if you could spray your wheat earlier, before weather keeps you out of the field for a week or your applicator is triple booked.

As 2019 planning kicks off, we suggest trying a fungicide that can make head scab management more flexible and help drive up yields and lower DON. The first-of-its-kind, Miravis® Ace fungicide, will allow you to spray as early as 50% head emergence through flowering. Powered by the active ingredient Adepidyn® fungicide, which is the first and only molecule with an SDHI mode of action available for head scab control, and propiconazole, Miravis Ace will allow you to protect the main head and tillers, and completely change how you manage head scab this year.

Take the pressure out of head scab management in 2019 and give yourself more time with this one-of-a-kind fungicide.
