Basic contents:

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

Accuracy of classifier:

Distribution of this species was determined according to regions where the Peach Leaf Curl is registered on fruit crops according to the published scientific materials. Within the limits of the disease area three zones of severity were allocated. The disease occurs at least 1 time in 2 years or almost annually in the zone of high severity, 1 time in 3 years in the zone of moderate development, and 1 time in 5 years in the zone of low severity.

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. Distribution of the disease is shown on a map within the limits of fruit-growing in the countries of the former USSR, i.e., in Georgia, Uzbekistan, Azerbaijan, Moldova, Kherson, Donetsk and Lugansk Regions of Ukraine. Epiphytic development of the Peach Leaf Curl occurs in Georgia, southern Ukraine, Crimea, Moldova, Turkmenistan, Ordubad area of Azerbaijan, central and southern areas of Krasnodar and Stavropol Territories, Adygea, Karachay-Cherkessia, Black Sea area. Areas of moderate development of the Peach leaf curl include the Dagestan, submontane areas of Azerbaijan, Armenia. The zone of low disease severity includes Kazakhstan, Kyrgyzstan, northern Rostov Region, Krasnodar and Stavropol Territories according to the following sources: Zakharzhevskaya (1954), Aslanov (1955), Paterilo (1958), Kostyuk & Kolomiets (1959), Kulibaba (1969), Babaev (1973), Kashiya (1974), Oganyan & Mkrtchan (1977), Smol'yakova (2000), Karatygin (2002).
