Curliness of peach leaves in the western part of Azerbaijan. Acta Biol. Univ. Daugavp., 24(1): 1-8. Abstract Leaf curl (Taphrina deformans (Berk.) Tul.) is one of the most common peach diseases of fungal origin. The disease manifests itself in the form of damage to leaves and shoots at the beginning of the growing season. Newly blossomed leaves become corrugated. With severe leaf curl damage and premature leaf fall, peach trees develop poorly, their winter hardiness is sharply reduced, and tree death is not uncommon. The article presents the results of a study of the prevalence, intensity of development and harmfulness of peach leaf curl (Taphrina deformans (Berk.) Tul.) in the western part of Azerbaijan. Analyzes of 3 years of research show that the disease is very widespread in all western regions of Azerbaijan. A comparative analysis of local Azerbaijani peach cultivars in relation to this disease is also provided. As a result of three years of research conducted in the western part of the country, it was found that the cultivar “Mai Chicheyi” is most affected by this disease. During field studies, fungicides were used: Abiga – Pik, VS (400 g/l copper oxychloride), Skor, KE (250 g/l difenoconazole), Bordeaux mixture, VRP (960 g/kg copper sulfate + 900 g/kg calcium hydroxide) and Kuproxat, KS (345 g/l tribasic copper sulfate) and their biological effectiveness was determined accordingly. During field studies, it was found that the Abiga-Pik fungicide gives the best results, because fungicide showed the highest biological effectiveness (80%) against leaf curl. Keywords: peach, leaf curl, cultivar, mushroom, distribution, development, harmfulness. *Corresponding author: Lala Huseynova.
