Abstract

The paper presents the results of the analysis of diseases of infectious fallout of winter wheat at the Field Experimental Station of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy from 2013–2015 to 2020–2021, depending on the tillage technology and weather conditions. It was shown that the main disease was pink snow mold (caused by Microdochium nivale). The analysis of the dynamics of the disease over 5 years showed that the prevalence was higher under zero tillage than under moldboard tillage (6.6 and 3.9%, respectively). The statistical analysis carried out showed an average positive correlation between soil density and disease prevalence (r=0.57 – for moldboard tillage and r=0.69 – for zero tillage). The data obtained indicate the need to adapt the protective measures against fallout diseases, taking into account the tillage technology, the cultivation zone and the climatic conditions.
