Vector map having one layer where the Powdery Mildew distribution area is shown by polygons.Accuracy of the classifier:
In the area of cotton, one zone of the Powdery Mildew area is determined.Method of map production:
Published materials are used for map drawing (Gorlenko, 1968; Peresypkin, 1974; Novotelnova, 2005). The disease is found everywhere in all countries of the former USSR where cotton is growing. Specification of the Powdery Mildew area is made according to the vector map of cotton greatest distribution regions in the territory of the former USSR (Koroleva et al., 2003.Reference citations:
