Rational arrangement of a network for disease survey on a regional scale
EPPO Bulletin 30 (1), 51-57
Abstract: The forecasting and warning system of Emilia-Romagna region (Italy) produces warnings for crop protection against diseases, using information from weather stations, biological surveys on a network of observation fields and simulation models. The network of field observations is crucial for the efficiency of the service but, unfortunately, the human and economic resources available for their management are usually less than needed. Therefore, the number of observation fields is insufficient to cover the entire territory uniformly, so that their geographical distribution increases in importance. In this work, a method for rational arrangement of observation fields on a regional scale is proposed. It uses models simulating crop growth and disease outbreak, both using meteorological data available on a 5-km mesh, to draw maps showing homogeneous areas within the territory. For the main pathogens of winter wheat (Erysiphe graminis, Puccinia striiformis, Puccinia recondita and Fusarium subsp.), disease risk is calculated when host plants are susceptible to infection, and both static and dynamic maps are drawn. The use of maps is discussed in arranging observation fields and in timing field surveys.
