The article analyzes the results of using the plant growth regulator Biosil® to increase the resistance of peach to the main leaf diseases (peach leaf curl (caused by Taphrina deformans (Berk.) Tul.) and shot-hole disease (caused by Stigmina carpophila (Lév.) M.B. Ellis)). The studies were carried out for four years (2018-2021) in peach orchards in the zone of humid subtropics of the Black Sea coast of the Caucasus (Sochi, Russia). The degree of development of peach leaf curl in the control variant was 10.2-25.0%. The degree of development of shot-hole disease in the control variant was 9.2-29.8%. The use of Biosil in combination with fungicides in half doses and in pure form makes it possible to increase the resistance of the crop to the studied diseases. The maximum biological efficiency (up to 70%) in relation to leaf curl and up to 60% in relation to shot-hole disease was observed when Biosil was used in a tank mixture with fungicides. The use of the plant growth regulator Biosil makes it possible to reduce the dose of fungicides in peach agrocenoses while protecting against peach leaf curl and shot-hole disease by half. The use of the studied growth regulator for four years did not lead to a decrease in its biological efficiency.

The research results of studies into different peach varieties grown on the Black Sea coast of the Krasnodar Territory and distinguished by high biochemical characteristics are presented. The research was carried out to identify promising peach varieties with different ripening periods and relative resistance to abiotic environmental factors. This work aimed to assess the biochemical composition of Persica vulgaris (Mill.) fruits. The peach varieties listed below were the focus of this study. A high quantity of ascorbic acid (from 11.30 to 16.16 mg%) was revealed in the fruits of the following varieties: Amsden, Redhaven, Veteran, Early Red, Springold, Larisa, Lebedev, Mainred, Slavny and Stark Earley White. The low content of this vitamin (9.21-10.05 mg%) was measured in Madeleine Pouillet (very early ripening), Sunbeam (medium ripening) and Anton Chekhov (late ripening) varieties. This is significantly lower (on average 6.53 mg%) compared to other varieties and to the control Redhaven variety, for which the value was 2.38 mg%. The maximum content of total sugar (8.66-12.11 %) was detected for Lebedev, Earley Red, Redhaven, Larisa and Veteran, whereas the minimum content (6.15-7.33 %) was noted for Madeleine Pouillet, Amsden, Stark Earley White, Collins, Mainred, Anton Chekhov and Glorious. The free acidity of the fruit according to the experiment was at the level of 0.67–1.39 %. High acidity was noted in the Springold, Amsden, Collins, Sunbeam and Slavny varieties. The content of soluble solids ranged between 11.00-15.50 %. The sugar-acid ratio, which indicates the degree of sweetness of peach fruits, corresponded to 5.65-14.58 units. The tasting assessment of the fruit was between 3.5 to 4.8 (on a five-point scale). The varieties having high biochemical parameters of the fruit and are most resistant to weather and climate changes have been identified: Redhaven, Earley Red, Lebedev, Larisa and Veteran.

Goal. To study the biological resistance of cherry varieties of different maturity against pest and to determine their number. Methods. Laboratory field. The population of cherry trees by pests was determined by conventional methods in the Research Garden of the NNVC Tavriya State Agrotechnological University. The final pest population of trees was assessed on a five-point scale. Results. The results of studying the phytosanitary condition of cherry plantations in the conditions of the Southern Steppe of Ukraine are given. It was found that in 2018, 8 species of pest predominated, and in 2019 — only 5. The permanent species of pest were cherry aphid, rose leafhopper, cherry fly and Turkestan mite. It should be noted that the population of the above pests in the years of research was at the level of 0—2 points. In 2018, single black weevils and geese were recorded in cherry plantations at the level of 1 point, and the following year these species were completely absent. During 2018, all varieties, except Dilema and Udivitelnaya were inhabited by mobile stages of red fruit mite from 0.6 to 3.0 specimens/leaf. In 2019, the population of hawthorn mites was observed above the economic threshold of harmfulness on the varieties Melitopol Black, Announcement and Talisman (3.3—7.3 specimens/leaf), which corresponds to 4—5 points. The number of California thyme in cherry plantations of almost all varieties was higher than the threshold value, the maximum was observed in the variety Melitopol black — 5.6—8.5 specimens/shield. Conclusions. Resistance of cherry varieties by groups of maturity to the presence of pests was not detected, all varieties to some extent were covered by harmful entomofauna. Ongoing monitoring studies in cherry plantations from the moment of bud burst to harvest can increase the effectiveness of protective measures by timely assessment of the population of each species of pest.
