Date of creation.



1: 20 000 000.

Accuracy of map.

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


"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

The vector map is composed of 2 thematic layers. Zones of distribution and severity are shown by polygons.

Accuracy of the classifier:

The zone of low severity is only marked within the area of Ascochyta Leaf and Pod Spot distribution as in all areas (Volga Basin region, the Far East, Krasnodar and Stavropol Territories, Kursk Region, Ukraine, Moldova, the Northern Caucasus) the disease meets seldom and sparsely.

Procedure of map drawing:

The area of distribution and zones of the fungus severity are drawn by results of the analysis of the published data. The data analysis has demonstrated the Ascochyta Leaf and Pod Spot has changed its high severity status into the status of seldom and sparsely meeting disease even in the Far East (Zaostrovnykh i dr., 2003; Badulin i dr., 1986; Kashuba, 1984; Milyakova i dr., 1984; Naumova, 1988; Naumova i dr., 1989; Prstakova i dr., 1983; Pidoplichko, 1978; Rodina, 1981). Nevertheless, the disease has a potential to become dangerous. Following these data, the zone of disease distribution and the zone of disease severity are shown as the territories of the largest soya distribution according the vector map of I.E. Koroleva et al. (2003). Vectoring of the scanned raster map is carried out by standard GIS-technologies.
