Structure and organization of warning services in Rheinland-Pfalz (Germany)

Abstract

Rheinland-Pfalz, a federal state in the south-western part of Germany, is an agricultural region with high crop diversity. For each branch of agriculture (arable, fruits, vegetables and ornamental plants), specific warning and information services have been installed. Advisory work, including warning services, is done by a central (LPP) and eight regional state institutions (SL V As). LPP provides the infrastructure for information dissemination, organizes data acquisition and supplies the farmers with general information on crop protection (availability of plant protection products, control strategies, etc.), SL V As collect data on current pest development and elaborate regional recommendations on field assessments and control measures to be taken by the farmers. Warning service information is transmitted to the farmers by info post (periodic letters), telephone-answering machines, fax services and, lately, via the Internet. Farmers are mainly interested in current disease and pest severity data, preferably on a local basis, to aid their decision-making in crop protection. The forecasting models and computer-aided decision-support systems run by the state crop protection service have become essential tools during the last four years. Their results, supplemented by field-monitoring data, serve as the main input for the warning services. The Internet, in conjunction with computerized decision-support systems, provides the means of ensuring an adequate supply of warning service information at a time when crop protection services are undergoing severe staff reductions.
