“…The following state datasets were used: a) pest monitoring and control datasets of the The data of the regional annual reports serve as a basis for compiling a summarizing annual report 'Forecast of phytosanitary condition of agrocenoses of Ukraine and recommendations for plant protection' further referred as (Forecast, 2020) (Stankevych & Zabrodina, 2016). Specialists of the state monitoring service annually monitor the density and phenology of 21 most important pests on grain crops.…”

We studied the long-term population dynamic`s (2005-2020) of six main insect pests of winter wheat (late wheat shoot fly, hessian fly, frit flies, cereal beetles, corn ground beetle and sun pest) in three climatic zones of Ukraine under conditions of increasing areas of application pesticides and global warming. The aim of the research was to investigate how these factors influence pest population dynamics. Comparison of sums of effective temperatures (SET) with standard values for different zones indicates significant climate warming over the past 15 years. Correlation analysis with two variables showed a general decrease in the numbers of most populations, especially in the steppe and forest-steppe zones.

At the same time, the ecological optimum of various types of harmful plant organisms is changing, the op timum zones for them are spreading to the north, due to which the pest population density is increasing [1][2][3][4]. As a result of the aggravation of the phytosanitary condition of agrocenoses, almost a third, and sometimes even a half, of agricultural crops are not harvested [5,6].…”

Goal. Development and implementation of new theories, methods, technologies and models that would allow more reliable forecasting of the development of pests and pathogens of agricultural crops. Methods. Analysis of innovative development of the Institute of Plant Protection of the National Academy of Agrarian Sciences of Ukraine and other institutions of the Scientific and Methodological Center «Protection of Plants» for 2001—2020. Isolation of those relating to the problem forecasting the development of pests and pathogens of plant diseases in agrocenoses of Ukraine. Results. The concept of formation of the phytosanitary state of crops and plantations under the conditions of climate change has been developed. The theory of the dynamics of the number of locusts and the prediction of emergency situations in the agricultural sphere of Ukraine has been developed. The widespread use of pheromone traps for diagnosing the phytosanitary state of agrocenoses of Ukraine is recommended. The cyclicity of outbreaks of mass reproduction of the Anisoplia austriaca beetle and the European corn borer was established, depending on the amount of solar activity. The possibility of applying GIS-technologies for the analysis of long-term data was studied. Predictive computer programs (models) of harvest shortages of rapeseed, sunflower, corn, sugar beet, and winter wheat from a complex of pests have been developed. An algorithm for the application of information technology programs for the analysis of multi-year dynamics of the phytosanitary state of agrocenoses has been developed. The role of the developed computer model of the development of leaf spots of grain crops in determining the moment for the most effective application of fungicides has been established. Methods of forecasting the development of pathogens of grape diseases in the South of Ukraine have been developed. A system of forecasting the phytosanitary state of agrocenoses of Ukraine in the conditions of the year and planning the implementation of protective measures has been developed. Conclusions. Innovative developments of the Scientific and Methodological Center «Plant Protection» make it possible to solve the following issues at a modern level: forecasting changes in the agrosphere based on the analysis of a long-term database of hydrothermal conditions and indicators of the phytosanitary state of agrocenoses; prevention of emergency situations in the agricultural sector on the basis of a modern monitoring system using GPS-navigation and the development of regulations for carrying out protective measures; forecasting the development of dangerous pests and diseases of agricultural crops; forecasting crop failures and determining the economic feasibility of chemical plant protection; forecasting the appearance and spread of quarantine pests.

Goal. To determine the species pathogens composition of sunflower diseases and to study the dynamics of development of the most harmful in the conditions of the western Forest-Steppe of Ukraine. Methods. The research was carried out during 2018—2019 in the research field of the Ukrainian Scientific Research Station on Plant Quarantine of Institute of Plant Protection using laboratory (pathogen identification) and field (examination of sunflower crops with sampling of plant material) methods. Results. Since the 1940s, the sunflower area in Ukraine has increased almost in 10 times: from 669 thousand hectares in 1939 to 5034 thousand hectares in 2017. The main crops — 75—80% are located in the steppe, and about 20% — in the Forest-Steppe zone. The sunflower crops are moving further to the west of Ukraine, where its areas increased in 2015—2017 by 1.7—6.4 times with large-scale climate change. However, the instability of weather conditions in this region and violations of the rules of agricultural technology lead to the defeat of sunflower plants by diseases of various etiologies. Researches studying the development of fungal diseases of sunflower have shown that the threat to crops was: embelizia (plant damage in the yellow basket phase was 73.3—100% with the development of the disease 36.7—75.5%); Alternaria (plant damage was 100% with the development of the disease 45—65.0%), verticillium wilt — the number of affected plants reached 35%, rust — for 100% of the affected plants, the intensity of sunflower damage was 3 points (for 5 score scale); the prevalence of phomosis and phomopsis for two years did not exceed 43.5%, and development — 15.4%. Conclusions. The most common during the study period (2018—2019) were: Alternaria alternata (Fr.Fr) Keissl.), embelizia (Alternaria helianthi Tub. et Nish.), verticillium wilt Verticillium albo-atrum Reinke et Berthold, V. dahliae Kleb., phomoses (Phoma oleraceae var. helianthi Sacc.) and phomopsis (Phomopsis helianthi Munt.Cvet. et al) in the western region of the Forest-Steppe of Ukraine.
