Date of creation:



1:20 000 000.

Accuracy of map:

It is created under the data taken from the open-published literature.


"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

Vector map. Area of distribution is shown by polygon (main distribution). Zone of harmfulness is shown by polygon.

Accuracy of the qualifier:

It is created on information taken from the open-published literature and maps of scale 1:5 000 000 - 1:100 000 000.
The weed area is subdivided into zones of main distribution and harm.

Procedure of map drawing:

The area and zone of harmfulness are outlined by results of the analysis of the cartographical materials taken from the open-published literature. A map of the rice growing area is used as a basis, because the Echinochloa oryzoides is the specialized weed of rice. The zone of main distribution is confirmed by the literature data (Agarkov, Gaidaev, 1978; Agarkov, Kirichenko, 1963; Galushko, 1978; Lysenko, Evsikov, 1969; Nikitin, 1957; Ul.yanova, 1983, 1998) and also by the floristic information on distribution (Flora of the USSR, 1934). Places of sporadic distribution are marked after the literature data (Grossgeim, 1939; Areas of distribution . (Volkov Ed., 1935). The zone of harmfulness is allocated after Nikitin (1983) and Sattibaev (1969).
