Date of creation:

18.03.2005

Scale:

1:20 000 000

Accuracy of map:

Map was created based on materials of maps of natural 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:

Zones of disease severity were allocated according to the following sources: Geshele & Vinogradova (1957), Nemlienko (1957), Kalashnikov & Shapiro (1962), Ivashchenko et al. (2000). The zones of high severity are characterized by 60-70% ears being affected (Nemlienko, 1957). The other zones established were zones of moderate severity. In these zones 7-10% ears are affected (Nemlienko, 1957). The zones characterized by low severity were not presented, because even a minimal infection leads to an accumulation of carcinogenic mycotoxins known as fumonisins in grain.

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. According to the following sources the disease is most harmful in the Northern Caucasus, in Central regions of the European part of Russia, in Siberia, Altai Territory, in the Far East, Ukraine, Georgia, and Byelorussia: Geshele & Vinogradova (1957), Nemlienko (1957), Ivashenko et al. (2000). The disease can continue its development during ear storage under conditions of high humidity and insufficient aeration (Kalashnikov & Shapiro, 1962).
