Apple scab (Venturia inaequalis) is the most important disease in apple production worldwide. Commercial production of apples without effective control of apple scab is not possible. Economically and ecologically effective scab management faces many challenges:

·The main commercial apple varieties are highly susceptible to apple scab.

·We have to reduce the environmental impact of scab control.

Apple scab (Venturia inaequalis) is the most important disease in apple production worldwide. Commercial production of apples without effective control of apple scab is not possible. Economically and ecologically effective scab management faces many challenges:

·The main commercial apple varieties are highly susceptible to apple scab.

·We have to reduce the environmental impact of scab control.

·We have to minimize the number of products that leave residues and their residue level on the fruit.

·The virulence of a local scab population adapts to locally used apple varieties and fungicides.

·All over Europe, scab populations are developing resistance against families of systemic fungicides.

·New label restrictions limit the number of applications of traditional contact fungicides like dithianon and captan.

To meet all these requirements fruitgrowers and their advisers need good knowledge of the infection biology of apple scab and the properties of the fungicides that are available. For their day-to-day decisions they need the support of a decision support system (DSS) that provides real time information on local infection conditions.

RIMpro is a cloud-based DSS for pest and disease management in fruit and wine production that is widely used in Europe and on other continents. Users get real-time information on development and forecast of apple scab infections. They can enter their spray records and let the system estimate the cover of previous fungicide applications based on leaf growth and rainfall. Now the system still relies on information from on-farm weather stations and local weather forecasts. In the near future the system will use high-resolution weather data that enables localized simulations for every orchard.
