On the study of weeds in wheat of the Samara region

The article presents the results of a study of crops and wheat grain samples in the Samara region in 2023. 12 fields of winter wheat and 17 fields of spring wheat with a total area of more than 3.1 thousand hectares were surveyed in 18 districts. The contamination of 231 wheat grain samples from the 2023 harvest was studied. A total of 191 taxa of plants associated with crops and finished products were found, with 181 species identified in crops and 60 taxa in wheat grains. The absence of diaspores of many weed species in finished products is due to the biological and phenological features of weeds, as well as the effective post-harvest cleaning of grain. The most commonly found weeds in wheat crops and grains are Chenopodium album , Delphinium consolida , Fallopia convolvulus и Panicum ruderale .
