The results of long-term phytopathological monitoring of the development of three pathosystems in autochthonous plantations, production and experimental crops of three types of forest tree species are shown: "common oak - powdery mildew," "walnut - anthracnose," "White pine - bubble rust." Research regions: CHR (Voronezh, Belgorod, Kursk, Lipetsk, Tambov regions), Kaliningrad, Oryol regions, Krasnodar Territory (Belorechensk, Natukhaevka village). Records of the spread and degree of development of fungal diseases (mycoses) are carried out according to the scales generally accepted and improved by the author. Attention is focused on the features of the development of specific pathosystems. The need for long-term monitoring of their development, accurate determination of the timing of the onset of the development of infection and their forecasting, its dynamics during the growing season and the period of reaching the maximum level is emphasized. The importance of establishing the type of trophic function and life strategy of disease agents, the optimal timing of assessment records, criteria and methods for determining the level of plant susceptibility in each case, which is a prerequisite for correct assessment and effective selection for resistance to appropriate mycoses, is discussed. The author's conclusion is justified by the large amount of long-term data processed by biological statistics methods. The results of long-term phytopathological monitoring of the development of three pathosystems in autochthonous plantations, production and experimental crops of three types of forest tree species are shown: "sweet oak - powdery dew," "walnut - anthracnose," "Veimutova pine - bubble rust."
