Map was created based on information taken from 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:
Vector map. Area of species distribution and zones of disease severity are shown by polygons.Accuracy of classifier:
Three zones of severity were allocated within the limits of the area of disease distribution. In the zone of high severity the annual development of peronosporosis results in yield losses to 50-75%; in the zone of moderate severity the development does not occur every year, and yield losses reach 40%; single records of the disease are demonstrated within the zone of low severity of the disease. The following sources were used to determine these zones: Krivchenko (1975), Makasheva (1973).Method of map production:
Scientists were given maps with boundaries of Oblasts and arable lands. After reviewing historic literature, species distribution was hand drawn on maps. If data were on the Oblast-level, distribution is on the Oblast level. In some cases, Oblast.s are further refined by boundaries of the Arable Land Map (Koroljeva et al., 2003). Hand drawn maps were scanned, georeferenced and vectorized. The analysis of the following materials published in the open press demonstrate that the greatest harm the disease causes is in the Non-Chernozem zone, in western areas of Central Chernozem zone, in Baltic States, Ukraine, Byelorussia: Krivchenko (1975), Golubev et al. (1979), Kirik et al. (1976), Kotova et al. (1965), Kraiko (1989), Makasheva (1973), Starostin et al. (1988), Cherepanova (1987). Areas of moderate severity coincide with the northern areas of the Northern Caucasus (Cherepanova, 1987). In other territories of the disease area it causes insignificant harm.Reference citations:
