Abstract

This article presents the results of studies conducted in 2019-2021 on table, sultana, and wine grape varieties that were severely affected by powdery mildew. Table grape varieties Kara Guzal, Katta Kurgan, and Taifi Rozov; sultana varieties Kara Kishmish, Ak Kishmish, and Kishmish Rozov; and wine grape varieties Bayan Shirey, Saperavi, and Rkatsiteli were found to be susceptible to powdery mildew, with infection rates on leaves ranging from 52.0% to 100%, on shoots from 33.3% to 80.0%, and on bunches from 42.0% to 95.0%. No grape varieties resistant to powdery mildew were observed during the study.
