First Report of Apple Chlorotic Leaf Spot Virus in Pome and Stone Fruit Trees in Azerbaijan.

Azerbaijan is major producer of fruit crops, such as pome and stone fruits, in the Caspian Sea and Caucasus Mountains areas (FAO Stat, 2022). No information is available on the occurrence of apple chlorotic leaf spot virus (ACLSV, genus Trichovirus, family Betaflexiviridae) in the country. Therefore, the main fruit tree production areas in Azerbaijan were surveyed for ACLSV during the 2017-2019 growing seasons by DAS-ELISA using ACLSV reagents (Neogen - Scotland, UK) (Clark and Adams 1977).
