Basic contents:

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

Accuracy of classifier:

The area represents disease distribution where Downy Mildew of Lucerne has been revealed according to scientific publications. In the disease area a zone of moderate disease severity is shown where the intensity of disease development is 11-50%. The other part of the area belongs to the zone of low disease severity where the intensity of its development does not exceed 10%.

Method of map production:

The data of Novotel'nova & Pystina (1985) was used as a prototype of the area. The area of the Downy Mildew of Lucerne was marked on a blank map within the limits of the largest areas of Lucerne distribution according to the vector layer of Koroljeva et al. (2003). In Russia the disease distribution zone includes Moscow, Belgorod, Voronezh, Kursk, Orel, Tambov, Tula, Astrakhan Regions, Bashkiria, Krasnodar and Stavropol Territories, Alania, Kabardino-Balkaria and Dagestan. It is also known in Western Siberia (Novosibirsk, Omsk Regions and Altai Territory) and in Eastern Siberia (Krasnoyarsk Territory, Buryatia). Outside the boundaries of Russia the Downy Mildew of Lucerne is distributed in the other countries of CIS and in the Baltics. Lithuania (Ermalavichute-Stanyavichene, 1970), the south of the Ukraine (Assaul, 1973), Kirghizia (Mamytova, 1990) and Uzbekistan (Faizieva, 1968) are included in the zone of moderate disease severity.
