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 3 thematic layers, where area and severity zones are shown by polygons.Accuracy of the classifier:
The area of distribution is divided into two zones of severity according with K.S. Sukhov et al. (1959) and Yu.I. Vlasov et al. (1973). In the zone of high severity the disease development is 30% and more, and epiphytoties are frequent; in the zone of moderate severity the Stolbur of Tomato development does not exceed 20-30%, and epiphytoties appear every 6th or 7th year.Procedure of the map drawing:
Zones of severity are drawn on a blank map based on published references. The zone of moderate severity includes Armenia, Georgia, Moldova, Ukraine, and Krasnodar Territory of Russia (Pogosyan, 1988; Khidesheli, 1990; Nikitina, 1963; Sukhov & Vovk, 1949). The zone of high severity of the Stolbur of Tomato includes Astrakhan, Volgograd Regions, and the Northern Caucasus (Samsonova et al., 2001; Tsyplenkov, 1973). A correction of the disease severity zones is executed according to Koroleva. vector map of the largest distribution areas of potato plantings (Koroleva et al., 2003).Sources of data:
