The species composition of weeds in spring wheat

This article presents the results of the study of agrobiocenosis of wheat field. When examining the agrobiocenosis of the wheat field, the species composition of weed vegetation characteristic of this crop in the Azov soil and climatic zone was determined. On the basis of the phytosanitary monitoring for 2015-2017 on the territory of the Lower don, 14 species of weed-field vegetation were found on the crops of spring wheat. The dominant and most dangerous species were field bodyak (Cirsium arvense), common ragweed ambrosia (Ambrosia artemisiforia), loach (Polygonum convolvulus).
