Meteorological and climatic factors determine most agricultural processes. This concerns not only the growth of plants, but also the development of pests or the epidemiology of fungal diseases. Therefore, microclimatic meteo measurements provide an important basis for the management of crop protection problems. Predictions and risk models for various diseases and pests are calculated based on these measurement data. They are thus indispensable for the development of targeted pest control in agriculture and for the production of high quality food with the least possible use of resources to treat the plants.
