The aim is to supply farmers with simple and intuitive tools to recognize and treat plant pathogens and nutrient deficiencies. PEAT developed an App (http://plantix.net) to provide smallholder farmer with customized information concerning best practices, information on preventive measures and independent options for action. The App offers the possibility to simply send a picture of the affected plant directly via smartphone and offers guidance through an easy identification process to determine the plant disease. All pictures sent via the App are tagged with coordinates. The resulting metadata provide valuable insights into the spatial distribution of cultivated crops and most significant plant diseases e.g. in form of high resolution maps.
