Date of creation:

Scale:

1: 20 000 000.

Accuracy of map:

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

Projection:

"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 4 thematic layers, where area and severity zones are shown by polygons.

Accuracy of the classifier:

The area of distribution is divided into three zones of severity according with Yu.I. Vlasov et al. (1990, 1992). In the zone of high severity, the disease development on cereals is 35-75% and higher, and epiphytoties are frequent; in the zone of moderate severity the BYDV epiphytoties appear every 5th to 8th year; in the zone of low severity the disease development is 10% and less.

Method of map production:

The area and zones of severity are drawn on a blank map based on published references. The zone of high severity includes the North Caucasus (particularly, Krasnodar and Stavropol Territories, Rostov Region) (Vlasov et al., 1990; 1992; Panarin, 1985; Tsyplenkov, Berim, 2005). The zone of moderate severity includes Baltic States, Byelorussia, Moldova, and also some regions of Ukraine. The BYDV disease distribution in other territories (including North-western region) does not exceed 10% (Tsyplenkov, Berim, 2005). A correction of the disease severity zones has been carried out according to Koroleva map (Koroleva, 2003) characterizing territories of the largest arable land distribution.
