![]() ![]() Goals / Objectives Objectives: The overall goal is to enable growers to reduce the number of applications and to reduce the environmental impact of fungicides to suppress late blight. ![]() Innovations and strengths of the DSS include: i)easy, automated access to highly specific historical weather, ii) easy, automated access to real-time "farm-specific" weather forecasts, iii)easy, real-time access to traditional late blight forecasts using forecast weather as well as historical weather, iv)real-time, interactive access to predictions from a complex simulation model of late blight, v)active alerts based on proximity to a known source of the pathogen as well as on weather. The improvements to the DSS include: i) expansion of the system to include tomato late blight as well as potato late blight ii) expansion of the system to include effective fungicides of low environmental impact iii) identification of the conditions calling for the "first" fungicide application in tomatoes and iv) development of active alerts to be sent to users when "high risk" conditions occur. Evaluations of the final DSS will be conducted in research plots on research farms and in demonstration plots on growers' farms. Experiments to expand and improve the DSS are proposed. The delivery mechanism for information is a web-based, interactive Decision Support System (DSS) that provides information to growers in real-time. Late blight is a major constraint in both potato production and in tomato production, so experiments will occur in both agro-ecosystems. Non Technical Summary The research is required to provide data to achieve the overall goal, which is: to enable fungicides to be used more efficiently in late blight management.
