Accuracy of map:

Created based on materials of maps of natural scale 1:33,000,000

Projection:

"Alber.s Equal Area Conic" 9, 1001, 7, 100, 0, 44, 68, 0, 0

Basic contents:

Vector map consists of polygons demonstrating area of disease distribution on Alfalfa and also a zone of moderate disease severity.

Accuracy of the classifier:

The region represents disease distribution where the Fusarium Disease of Alfalfa has been revealed according to scientific publications. The area of disease distribution is similar to the zone of moderate disease severity (10-25%).

Method of map production:

The area of Fusarium Disease of Alfalfa was marked on a blank map. In the Former Soviet Union the disease was registered in Voronezh Region (Ryzhkova, 1951, quot. on: Karimov, 1961), Rostov Region, Stavropol Territory (Alpat.ev & Shestiperova, 1981; Kazantseva et al., 1997), Krasnodar Territory (Alpat.ev & Shestiperova, 1981; Petrovskaya, 1981), Baltic States (Shal.tyanis, 1970, quot. on: Petrovskaya, 1981), Ukraine (Poltava Region (Karimov, 1961), Kharkiv Region (Zagovora, 1978)) and Uzbekistan (Toshkent) (Zaprometov, 1921, quot. on: Karimov, 1961). The disease area of distribution is similar to the zone of moderate disease severity (10-25%) (Karimov, 1961; Zagovora, 1978; Alpat.ev & Shestiperova, 1981; Petrovskaya, 1981; Kazantseva et al., 1997). Registration and vectorization of raster map were carried out using standard GIS-technologies.
