Some 3000 ha are covered by vineyards in the wine‐producing area of Rheingau (Hessen, DE). By cooperation between the Forschungsanstalt Geisenheim (Research Station for Viticulture), the advisory station for viticulture and the Agrometeorological Advisory and Research Station of the German Weather Service, a new system has been established to send a fax to wine‐growers twice a week, containing both weather and agrometeorological information and remarks on plant protection, fertilization and soil cultivation. The data base consists of three columns: (1) data from different weather stations, (2) data from weather forecasts and (3) estimations and soil analyses made in plant stands. The following electronically supported procedures can be offered to the user at present: (1) risk forecast for Plasmopara viticola; (2) forecast of flight date for Eupoecilia ambiguella and Lobesia botrana; (3) advice on nitrogen fertilization; (4) evaporation of plant protection treatments; (5) calculation of soil moisture for the management of soil cultivation in grassed‐over or normally ploughed vineyards. The new advisory system leads to decreased expenditure on plant protection products and soil‐applied fertilizers.
