Vector map having one layer, where the Alternaria Leaf Spot zone of severity is shown on the territory of the former USSR by polygon.Accuracy of the classifier:
In the cotton area, the zone of Alternaria Leaf Spot severity is determined.Method of map production:
Published materials are used for map drawing (Gorlenko, 1968; Peresypkin, 1974; 1987). The disease is registered in Uzbekistan, Kazakhstan, Tajikistan, Turkmenistan, Azerbaijan, and Armenia. Specification of the distribution area is made on vector map of the cotton greatest distribution according to I.E. Koroleva et al. (2003).Reference citations:
