It is created on information taken from the map of scale 1: 33 000 000.Projection.

The vector map is composed of 3 thematic layers being shown by polygons.Accuracy of the classifier.
The area of distribution is divided into zones of high and moderate severity. In the zone of high severity the disease is widespread, yield losses reach 50% and more (Dubovitskaya, 1987); in the zone of moderate severity the yield losses do not exceed 50% (Ganzhelo, 1990).Procedure of the map drawing.
The area of distribution and zones of the fungus severity are is drawn by results of the analysis of the published data and cartographical material (Zaostrovnykh et al., 2003; Dubovitskaya, 1987; Ganzhelo, 1990; Danilets et al., 1988; Zhukovskaya, 1977; Laptiev, 2000; Milyakova et al., 1984; Podkina et al., 1982; Prostakova et al., 1983, 1992). According with the data, the disease area is drawn along areas of industrial cultivation of soybean (vector layer by I.E. Koroleva et al. (2003). The zone of high severity includes Moldova, the Black Sea coastal areas of Ukraine, and arable lands with soya crops in Rostov Region, Krasnodar and Stavropol Territories of Russia. In addition, the disease is very harmful in Amur Region, Khabarovsk and Primorskii Territories of the Far East. The zone of moderate severity includes Kursk Region, northwestern part of Volgograd Region, and also arable lands with soya crops in Saratov and Samara Regions. Vectoring of the scanned raster map is carried out by standard GIS-technologies.Sources of the data.
