Since each plant develops immunity to drugs over a period of time, thus many agricultural producers strive to improve and find new methods of destroying parasites harming plants. Modern agricultural production reasonably puts forward the requirements for increasing the profitability and environmental safety of the products obtained. In this regard, there are great opportunities for the effective use of mechanical and physical methods of weed control, instead of problematic options for the use of herbicides. The improvement of tillage systems, in terms of greening agriculture, is primarily associated with their adaptation to a variety of soil and climatic conditions and in-depth differentiation in accordance with the agro-ecological requirements of crops. An optimally selected tillage system maintains a favorable phytosanitary condition of the soil for plants. Based on previous research in this area, the experience was studied and referred. The article presents the results of the number of treatments for the predominant weeds in the Southern Federal District of the Russian Federation. Taking into account early studies, it was revealed that due to the increased share of grain crops in the crop rotation, the amount of weed vegetation in the field increases over the years. We chose the chisel treatment method by the working bodies of the “Ranch” with a reservoir turnover of 0.12-0.15 m. When taking into account the clogging, the methods of A.M. Tulikov were used. There is a noticeable reduction in the contamination of certain plant species in all the years of the study for 2020-2022. Therefore, the goal was set to study each type of weed vegetation after cultivations prevailing in the Southern Federal District. The results were reliable and complete. By carrying out multiple cultivations, it was possible to identify weed vegetation most susceptible to processing by chisel organs of the “RANCH” without the introduction of chemical means of protection.
