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.
