Growers desire a tool to suppress disease more effectively and more efficiently.
Society desires a tool that will lead to decreased use of fungicide. Plant disease epidemiologists desire tools that use the results of their research. However disappointment results from the expectation that the forecast will work perfectly when introduced. In general, farmers have found forecasts less helpful than hoped. Therefore adoption of forecasts by farmers has been less than desired by epidemiologists, and reductions in use of fungicide have been less than desired by environmentalists.
