Basic contents:

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

Accuracy of classifier:

Within the general distribution area two zones of damage were presented based on the literature of Chumakov & Zakharova (1990). The zone of moderate damage represents areas where 11-25% of plants are infected with Phomosis. In the zone of high damage 26-100% of plants are infected with Phomosis.

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 severity zones were mainly determined according to Chumakov & Zakharova (1990). The borders of the zone of high severity in the Far East, the Caucasus, and Krasnodar Territory were adjusted according to the following sources: Sal.nikova (1952), Kvashnina (1935), Rozhdestvenskii (1940). Moderate severity of the disease was reported in the Ukraine, Byelorussia, Moldavia, and NW region according to the following sources: Mikhal.chuk (1984), Peresypkin (1969), Ruzinov (1953). Low disease severity was reported in Georgia, Voronezh, Samara, Sverdlovsk Regions, and Chuvashia according to Dolidze (1980) and Osnitskaya (1969).
