Abstract

Northern corn leaf blight, gray leaf spot, and tar spot caused an estimated loss of over $100 per acre for Ohio corn producers in 2021. These significant losses prompted grower interest in the use of flutriafol at-plant corn fungicides in part to their systemic nature and ability to be planter-applied. On-farm research is an opportunity for producers to evaluate products or practices and generate individualized data. In 2022, Ohio State University Extension developed an on-farm research protocol to determine yield response to an at-plant soil application of flutriafol (Xyway® LFR®) fungicide with or without a supplemental foliar fungicide application. This presentation will summarize nine on-farm trials conducted during the 2022 growing season that measured the effect of treatments on final stand, yield, and disease severity. Information from these trials will be used to improve corn disease management recommendations for Ohio producers, and overall is an example of how extension professionals can engage producers via on-farm research efforts.
