Methods for feasible detection of scoring data and usage for varible plant protection in arable farming The spare use of pesticides is essential not only for economic reasons but also for reasons of nature and environmental protection. Our aim is to develop a method by which farmers and contractors easily and with the aid of software tools can rate crops. These data can be used to create a map for site-specific application of pesticides and then send to the existing technology (sprayer with GPS section control). Concept development, Research of possible external data sources integration Development of the module rating app Development of the module decision assistant Development of the module application map Development of the module for transferring the data to other EDP systems for verification and documentation Testing the modules, tying the modules for the overall solution, test, redesign
