Abstract

To carry out effective plant protection measures, it is necessary to take into account all the factors affecting the quality of the crop. The aim of our research was to study the degree of development of leaf diseases of winter wheat and the rate of infestation of crops, depending on the tillage method. The studies were carried out in 2019-2020 at the experimental plots of “Kuban educational farm” in Krasnodar. For the research, four experimental plots with Steppe variety of soft winter wheat were created, where various soil cultivation systems were applied: 1 - No-Till (zero technology), 2 - moldboard-free technology, 3 - recommended, 4 - moldboard technology. The article presents data on the degree of development of diseases and the degree of infestation of winter wheat plants in the crops of test plots with various tillage systems. It was found that the most preferable is the use of the recommended type of treatment, since with it the least number of diseases develops and the degree of development of pathogens is reduced by 2-3 times in comparison with other options. The influence of the tillage method on the number and composition of phytopathogen spores was revealed.

Highlights

Wheat is one of the first plants introduced by man into culture, and at the moment it is the main crop that provides food for the world's population

The “Steppe” variety of soft winter wheat was chosen as the object of the study, which was submitted for the State variety testing in 2015

Summary

Introduction

Wheat is one of the first plants introduced by man into culture, and at the moment it is the main crop that provides food for the world's population. The aim of the research is to study the influence of the tillage method on the development of leaf diseases of winter wheat and the contamination of crops with pathogens. To determine the degree of development of wheat leaf diseases, field surveys were carried out using international scales of plant infestation [9,10].
