A fungicide application can have a significant impact on final winter wheat yields. That’s according to the latest report from the Ontario Cereal Crops Committee (OCCC) which reveals that fungicides, in 2024 trials, delivered an average 12 to 13 bushels per acre yield advantage when compared to the same variety without a fungicide application.
University of Guelph associate professor Dr. Dave Hooker says individual varieties show a wide range of responses, with some varieties showing no response to fungicides and others showing up to a 40-bushel per acre advantage. The variability in response is influenced by disease conditions, with susceptible varieties showing greater benefits from fungicide applications.
On this episode of the RealAgriculture Wheat School, we catch up with Hooker at Ridgetown College, one of the trial locations, where the OCCC gathers trial data to identify wheat varieties that perform well without fungicide, as well as those that require fungicide application to reach their full yield potential. The trials can be found at GoCrops.ca.
About 50 wheat varieties are tested annually in OCCC trials. When the data is tabulated, the goal is to communicate the findings from the trials to help farmers make informed decisions on variety selection and fungicide management. Watch the video below.
