​​Chemical Control of Foliar Plant Diseases in Potato: Application of Fungicides

​This presentation will help consultants, growers, and other practitioners in areas in which potatoes are produced. Information will be presented detailing where fungicides can be found in the potato canopy following applications by different methods, how much of the material applied remains by canopy level nearly a week later, and what results are produced from repeated applications related to fungicide amount through time. Information is also provided on how fungicide amounts can be increased by some application methods, what effects result from increasing or decreasing water amounts used during application fungicide deposition, and why timing of application is important to get the best disease control possible.
