Basic contents:

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

Accuracy of classifier:

The region represents disease distribution, where the Powdery Mildew of Lucerne has been revealed according to scientific publications. The area of disease distribution is similar to the low severity (to 10%) zone of the disease that was determined.

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. In the Former Soviet Union the disease has been registered along the Baltic Sea coast, in Orel, Khar.kiv, Samara, Tula, Kursk, in Kiev according to Yachevskii (1927), in Nizhnii Novgorod according to Luk.yanova et al. (2001), in Voronezh according to Karimov (1961), in Saratov according to Borisov et al. (1999), in Omsk Regions according to Kalinina et al. (1985), in the Krasnodar Territory according to Berdysh (2004), in the Ukraine according to Karimov (1961) and Zagovora et al. (1978), in Armenia according to Karimov (1961), in the North Caucasus according to Karimov (1961). The fungus has not recently been found in Central Asia on cultivated lucerne, replaced by Leveillula taurica f. medicaginis (Karimov, 1961). It is found on other lucerne species in Kyrgyzstan (Yssyk-Kol Region) and Tajikistan (the Turkestan ridge). The following sources demonstrate that the disease area of distribution is similar to the zone of its low severity (to 10%): Kalinina et al. (1985), Borisov et al. (1999), Luk'yanova et al. (2001), Berdysh (2004).
