First report of garden cucumber root rot caused by Globisporangium ultimum var. ultimum in Kyrgyzstan

Abstract

Garden cucumber (Cucumis sativus L.) has been commonly cultivated in a wide area in Kyrgyzstan. In 2019, wilting and yellowing symptoms were observed on cucumber plants in three fields planted in Lenin district, Bishkek, Kyrgyzstan, with a general incidence of 6%. Diseased plants showing root rot symptoms were subjected to pathogen isolation. Infected tissues were superficially disinfected in 1% NaOCl for 1 min and placed to Petri dishes containing water agar (agar 15 g/l) amended with 0.1 g/l streptomycin sulfate.
