This report gives an interesting example of the application and practical economic use of meteorological data on temperature and humidity and their effect on the life cycle of downy mildew. Data obtained from the instruments and the results of investigations carried out on a scientific level were compared with practical findings obtained by direct observation of the vines, special attention being given the appearance of any fog or dripping dew such as could start a period of incubation. In order that such attempts may prove successful when carried on collectively over such a wide range of territory, there must be within the area at least a certain minimum degree of uniformity in the conditions of the environment and, in particular, of the climatic conditions. There must also be a certain period of time which falls between the various incubation cycles of the parasitic fungus which occur over a period of time.
