Basic contents:

Vector map. Area of species distribution and zones of disease severity are shown by polygons.

Accuracy of classifier:

All regions represent the distribution of disease, where Powdery Mildew of Wheat was revealed according to scientific publications. The disease area is subdivided into high (31-50%), moderate (11-30%) and low (to 10%) disease severity zones of the Powdery Mildew.

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. The following sources were used as a basis for map production: Chumakov & Minkevich (1969, 1971), Sanin et al. (1999, 2002), Levashova (1994), Cherebedova et al. (1980), Malutina (1965), Tursumbaev (1972) and Mzhavandadze (1971). 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.
