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

Basic contents:

Vector map consists of two thematic layers, where zones of distribution and harm are shown by polygons.

Accuracy of classifier:

In the disease area the zone of severity is allocated, where the number of infected plants rise to 10% and more.

Procedure of map drawing:

The zone of distribution is identified by results of the analysis of the published data on fungus distribution (Dzhumbaev, 1970; Ishkova, 2002; Levitin, Tuterev, 2003). In this zone the disease development is basically occasional and weak; yield losses have no economical significance. The disease severity zone borders are allocated after Buga & Ushkevich (1982), T. Ishkova et al., (2002) and M. Levitin & S. Tuterev.
