Winter wheat is the main food crop in Russia, its sown area is more than 16 million hectares, including about 5 million hectares in the North Caucasus. An important factor influencing crop yield is weed infestation. The purpose of the study is a comparative analysis of the phytosanitary state of winter wheat crops in terms of the development of weeds in various agroclimatic zones of the North Caucasus. The location of the study is the Stavropol Territory, the Chechen Republic and the Republic of North Ossetia-Alania. Comparative analysis of winter wheat weed infestation in the Stavropol Territory, the Chechen Republic and the Republic of North Ossetia-Alania in the period 2018-2023. indicates a widespread increase in the area of infested crops. The type of weediness is complex: annual - 63.70%, perennial, respectively - 36.30%. In winter wheat crops in the surveyed area, early spring and wintering weeds predominate, which is explained by the biological characteristics of the crop. More than 15% of weeds are representatives of the Poaceae family. Traditionally, herbicides are used to control weeds, with preference given to two-component broad-spectrum herbicides or tank mixtures of herbicides. At the same time, monitoring the floristic composition of weeds is the basis for the selection of chemical plant protection products.
