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.

Leaf airborne diseases cause major shortfalls in agricultural crops. The introduction of technical means can significantly improve early-warning systems for plant diseases as well as provide timely and accurate forecasts. In this paper, we aim to evaluate the possibilities of detecting a phytopathogenic infection using a spore-catching device developed at the Federal Research Center of Biological Plant Protection (FRCBPP) on winter wheat varieties of different levels of susceptibility to major economically important leaf diseases, taking into account climatic conditions. The device captures spores in the surface layer of air among crop plants. We conducted research in the experimental fields of FRCBPP in 2019–2021. The objects of the study were four cultivars of winter wheat. They were selected according to the degree of resistance to various leaf diseases. We studied the progress of wheat diseases according to generally accepted international scales the onset of the first manifestations to their maximum development. We studied the aerogenic infection in wheat crops using the FRCBPP developed portable device for determining the infestation of plants. Sampling was carried out in the same period as the visual assessment. The samples were taken in the crops of each variety at five points. The sampling time was one minute. As a result of research on experimental crops of four varieties of winter wheat, we observed the development of such diseases as powdery mildew (Erysiphe graminis), yellow spot (Pyrenophora tritici-repentis), septoria leaf spot (Septoria tritici), yellow (Puccinia striiformis) and brown rust (Puccinia triticina). In a laboratory study of samples under a light microscope, all of the listed pathogens were found except for septoria leaf spot. Two-way analysis of variance confirmed the statistically significant separate and cumulative influence of the cultivar and year factor on winter wheat diseases. A generalized correlation analysis for three growing seasons (2019–2021) showed that an average statistically significant correlation coefficient (0.5–0.6) remains for the total groups for powdery mildew, yellow and brown rust. This indicator for the causative agent of yellow spot was equal to 0.4 with a high level of statistical significance. Thus, we conclude that by using a spore-catching device, it is possible to identify spores of economically significant pathogens in winter wheat crops and predict the further development of pathogens, taking into account the cultivar and annual climate factors.

A new aspiration system using the dynamic pressure of multicopter propellers is described. A comparative assessment of the efficiency of the PSL-3 device fitted with the OZR-1mp reference sampler is carried out in field conditions.

Aim. To analyze the data in the available literature regarding the effect of various tillages on the development and prevalence of wheat pathogens.Discussion. According to the literature, the existing tillage technologies – classical, minimal and zero – significantly affect the development of pathogens that cause the development of wheat diseases in regions that differ in soil and climatic conditions. In Russia and other countries near and far, the issue of combating diseases of agricultural crops is dealt with by chemical, biological and agrotechnical methods. Despite the fact that agrotechnical methods are of the utmost importance in the general system of measures to protect plants from damage, for a long‐time agricultural technology as a means of plant protection was underestimated. However, many agricultural techniques, as well as genetics and selection, increase the resistance of plants to damage.Conclusion. As a result of these techniques, it is possible to create environmental conditions that will be unfavourable for the reproduction of diseases. At the present time, opinion is firmly established that separately undertaken, isolated methods cannot properly solve the problem of protecting plants from pathogens of agricultural crops. Only a set of methods combined into a system of measures provides a solid basis for plant protection. And in this system of measures, the role of agricultural practices is extremely large.

Recently, there has been interest from the scientific community and agricultural producers in finding means of attracting insects using LED-based light traps. The purpose of these studies is to assess the biodiversity of tomato agrocenoses in open and protected ground, to identify the most massive taxa present in agrocenoses using light traps. The studies were carried out in the period from 15 July to 21 July 2021 on tomato in the experimental production plots of the tomato farmer Erokhin E.A. and in the greenhouses of the farmer Tyrtychny S. A. (the village of Strelka, Temryuk district) in the northwestern zone Krasnodar Territory of the Russian Federation. Studies carried out using light traps designed by the Federal State Budgetary Scientific Institution «Federal Research Center of Biological Plant Protection» (FRCBPP) made it possible to identify the species diversity of arthropods in tomato agrocenosis, to obtain the dynamics of the number of harmful, beneficial and indifferent entomofauna. Representatives of the following orders dominated in number on the open ground: Coleoptera (68–82%), Hemiptera (15–26%) and Diptera (2–6%), while in the greenhouse there were Lepidoptera (39–61%), Diptera (10 –18%) and Coleoptera (10–40%). Representatives of the Lepidoptera families - Cossidae, Noctuidae, Pyraustidae and Crambidae, and the Coleoptera families - Carabidae, Cerambycidae, Coccinellidae, Dytiscidae, Elateridae, Geotrupidae, Heteroceridae, Hydrophylidae, Scarabaeidae were attracted in open ground as well as in the greenhouse.
