In this study the intensity of a Cirsium arvense (L.)SCOP infestation was monitored in a 12 ha experimental field, where malting barley was grown. Furthermore, the measurement was completed with localized C.arvense patches on the same field. Acquired data were evaluated GIS using a kriging procedure. An application map was created according to a field survey and a site-specific herbicide application against C.arvense was carried out. A spray treatment was only necessary on approximately 74%of the total field area. The efficiency of the herbicide application was evaluated in the field after herbicide application by using the sama evaluation method. The NDVI index from satellite pictures proved the exact demarcation of the area with herbicide treatment and the area without herbicide treatment. Comparison of the C.arvense infestation map and soil electrical conductivity (ECa)map showed a good correlation between a high C.arvense infestation and high ECa values. The statistical analysis confirmed this dependence of C.arvense infestation on ECa values [r=0.64 - P<0.01)]. ER -
