Abstract: In this article the influence of abiotic factors on agrophytocoenoses is considered, these are: moisture supply, rising air temperature, increasing carbon dioxide concentration, and the probability of environmental risks in particular. The degree of ecological risk has been established. Environmental risks due to the influence of climate change on agrophytocoenoses have been identified and substantiated and are: the spread of adventive and invasive plant species; loss of competitiveness of agrophytocoenosis crops relative to segetal phytobiota; increase in the number of species and distribution areas of segetal phytobiota; change in the sown area, productivity and quality of the harvest of agricultural crops; acquisition of tolerance of segetal phytobiota of agrocoenoses to herbicides and deterioration of their effectiveness under agroclimatic fluctuations. All of the above-mentioned environmental risks, which are associated with aggravation of the phytosanitary condition of crops inevitably, lead to a loss of the productivity of agrocoenoses. They lead to a decrease in the quality of the obtained plant and agricultural products as well. Along with the loss of productivity of the weedy agrocoenosis, there are environmental risks caused by the increased need for the use of plant protection products to ensure the control of the phytosanitary state of the agrocoenosis. Ensuring the reduction of environmental risks and enhancing the ecological safety of agrocoenoses is timely environmental monitoring, considering appropriate agronomic, protective, and preventive measures. These measures increase the adaptive capacity of agrocoenoses. r atmospheric levels in analyzing pertinent cases.
