Vector map having four layers, where the area of sunflower and zones of severity of Charcoal Rot are shown by polygons.Accuracy of the classifier:
Three zones of the disease severity are determined in the sunflower area in the territories of the former USSR. In the zone of high disease severity, crop losses reach 20% on average. In the zone of moderate severity, crop losses are 1% to 10%. In the zone of low severity, the crop losses are less than 1%.Method of map production:
Published materials are used for map drawing (Kukin, 1982; Yakutkin, 2001). The zone of high disease severity includes the North Caucasus in Russia, southern steppe of Ukraine including Crimea, central and southern Moldova. The zone of moderate severity includes the central, northern and western Ukraine, and northern Moldova. The zone of low disease severity includes the southwestern and southern parts of the Belgorod and Voronezh Regions of Russia. Specification of the disease area and severity zones are made according to vector map of I.E.Koroleva et al. (2003) characterizing regions with the greatest distribution of sunflower.Reference citations:
