Development and Expansion of Disease Management Decision-Making Tools Across Multiple Soybean Regions, Year 3

Soybean growers across the U.S. face several common yield limiting diseases that can result in annual losses from $2.2 to $4.6 million. Decision making tools provide a method to target fungicide applications, simultaneously improving fungicide efficacy and proactively delaying the development of fungicide resistance. Research will be conducted to help develop and validate soybean disease forecasting systems. Specifically, a foliar fungicide field trial on soybean will be conducted, and spore traps will be deployed. Slides from the spore traps will be collected weekly and sent to a designated laboratory for analysis. In addition, multi-state Extension publications will be developed to help educate stakeholders about management of important soybean diseases.
