One of the urgent problems of reducing crop yields is the unsatisfactory phytosanitary condition of the fields, leading to economic losses in agriculture, especially when switching to resource-saving technologies [1, 2]. The aim of the work is to study the phytosanitary condition of agrocenoses depending on the method of tillage. For this, plots were laid in the Orenburg district of the Orenburg region. As a result of the experiments carried out with various processing methods, it was noticed that in experiments with small loosening, the amount of weed-field vegetation increased by 2 times, for example, FPV (phenoceptic threshold of harmfulness) of Panicum miliaceum L. was exceeded by 36 times, revealed a change in life forms towards xerophytic flora. On the same experimental plots conducted a study on the presence of root rot. In the experiment with deep tillage (plowing) of spring wheat, 46% of the plants affected by Fusarium rot were observed, and 50% of the plants affected by the pathogen were counted on the experience in tillage.
