Scale:

1:20,000,000.

Accuracy of map:

Created on the basis of a map of the scale 1: 33,000,000.

Projection:

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

Basic contents:

Vector map consisting of 4 thematic layers, where the distribution and zones of severity are shown by polygons.

Accuracy of classifier:

In the disease area the zones of low (6-10%), moderate (11-25%) and high incidence (26% to 100% of plants are affected by P. schachtii) are outlined. The zones are marked according to method by A.E.Chumakov & T.I.Zakharova (1990).

Method of map production:

Zones of severity are drawn on a blank map based on open-published references (Pozhar, 1961, 1963, 1964; Popova, 1968, 1969, 1971; Al.khovskaya, 1969; Popova & Zlotnikov, 1970; Batalova et al., 1973; Pozhar et al., 1978, 1979). The zone of high severity of the disease (26% and higher) is marked in Ukraine (Ternopil., Rivne, Sumy, and Kyiv Regions), in Voronezh, Kursk, Orel Regions, and in Krasnodar Territory. The zone of moderate severity (11 to 25%) encompasses Lipetsk, Penza, Poltava, Vinnytsya, Zhytomyr, Khmel.nytskyi, and Kirovohrad Regions, Kyrgyzstan and Baltic States. The low severity of the disease (not more than 10%) has been recorded in southern and western regions of Ukraine, in Byelorussia, Moldova, Stavropol. Territory, Kazakhstan, and central areas of the European part of the former USSR. Registration and vectoring of raster map depicting zones of severity of Downy Mildew on sugar beet are executed by standard means of GIS-technologies.
