“…Phytosanitary surveys of the plantings of the crops for signs of plant damage by alternaria (A. alternata species) were carried out from June 17 to July 02, 2020 in the Krasnodar region in Pavlovsky District, on the production fields of the ZAO Yubileinoye. Monitoring was carried out in two ways: classical -a visual assessment of the development and spreading of diseases according to the "Methodological guidelines for registration tests of fungicides in agriculture" [16] and modern -by determining the contamination of plants using the OZR-1mp device [17] according to the method described in the article «Development of technology for detecting foci of wheat rust diseases» [13]. The type of the alternaria pathogen was determined according to the key (2007) [18].…”

The effect of the biofungicide BFTIM KS-2, Zh on the development and spreading of the Alternaria alternata fungus on vegetable crops (tomato, pepper, eggplant) was studied using classical and modern methods of phytosanitary monitoring. The research was carried out in Krasnodar region in the Pavlovsky District, on the production fields of the ZAO Yubileinoye. To assess the development and spreading of the disease, the classical visual method was used, as well as a modern method for determining the congestion rate of plantings using the OZR-1mp spore trap.The article presents data on the development and spreading of A. alternata, the number of fungal spores on vegetable crops before and after treatments with the biofungicide. It was found that the use of the biological product reduces the development and spreading of the phytopathogen. Its influence is the most effective on tomato and eggplant crops. Also, in the course of research, the possibility of using a spore trap for monitoring Alternaria on vegetable crops has been shown.

In order to manage the phytosanitary situation on the sowings and get the maximum yields of high quality, at first it is necessary to estimate the condition of the protected crop. Based on this estimation, in future it is possible to establish the most effective and economically justified protection system. Grain crops are the most important strategic crops that ensure food security around the world. According to the FAO the world crop losses caused by pests have reached up to 40 % where fungal pathogens have played the most significant role. Therefore, the most important task of phytosanitary monitoring is the timely detection and identification of the disease before the beginning of symptoms at the earliest stages of pathogen development, which becomes possible when the infectious beginning of the disease has been detected. When monitoring fungal diseases, spore-catching equipment allow this issue to be solved. The purpose of the current review was to describe the existing developments of spore-catching equipment for monitoring grain crop diseases and to identify promising areas for using devices on crops to improve protective measures’ efficiency. The introduction has briefly described the classical methods of monitoring and the relatively new methods currently used. In the main part there has been considered a spore-catching equipment developed and used both in foreign and domestic practice. There have been analyzed the methods of using spore-catching equipment and given the examples of the use of these devices in monitoring crop diseases. In the conclusions there have been summarized the trends in the development of technical support for phytosanitary monitoring and shown areas that have been found promising for further research.
