Stemphylium vesicarium causing Sansevieria trifasciata (viper’s bowstring hemp) leaf blight in Iran

Abstract

Leaves of Sansevieria trifasciata with leaf blight symptoms were collected from greenhouses of Miyandoab, West Azerbaijan province, Iran, during the summer of 2016. Leaf blight symptoms were large, elongated and gray to pale brown with brown margins. Three single spore isolates were obtained from diseased leaves and the pathogenicity of each isolate to plants was confirmed by inoculation tests based on Koch's postulates. The pathogen was identified as Stemphylium vesicarium, based on both morphological characteristics and sequencing of the Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene. This is the first report of Stemphylium vesicarium causing leaf blight on Sansevieria trifasciata in Iran and the world.

Identification, pathogenicity and histopathology of Colletotrichum sansevieriae causing anthracnose of Sansevieria trifasciata in Malaysia

“…Previously, most pathogenicity tests on S. trifasciata leaves that resulted in varying degrees of disease symptoms involved wounding inoculation (Nakamura et al 2006; Gautam et al 2012; Ahmadpour and Poursafar 2018). This might possibly be due to the thick cuticle on the leaves resisting plant pathogens or the entry of pathogens through roots (Carlquist and Schneider 2007; Ziv et al 2018).…”

“…The pathogens were comprised of C. neosansevieriae, Chaetomella sp., Lasiodiplodia sp., Neoscytalidium dimidiatum and Stemphylium sp. (Li et al 2013;Crous et al 2015;Kee et al 2017;Ahmadpour and Poursafar 2018;Kee et al 2018Kee et al , 2019.…”

“…Sansevieria trifasciata was documented as the host of several fungal pathogens including Neoscytalidium dimidiatum , Stemphylium vesicarium , Lasiodiplodia spp. and Colletotrichum sansevieriae (Ahmadpour & Poursafar, 2018; Aldaoud, DeAlwis, Salib, Cunnington, & Doughty, 2011; Kee, Suhaimi, Zakaria, & Mohd, 2017; Kee et al, 2019). Besides, leaf spot of S. trifasciata was reported to be caused by several pathogens, namely C. neosansevieriae , Chaetomella and Stemphylium lycopersici (Crous et al, 2015; Kee, Zakaria, & Mohd, 2018; Li, Zhou, Lu, & Ye, 2013).…”

First Report on Colletotrichum sansevieriae Causing Anthracnose of Sansevieria trifasciata in Germany

“…However, several fungal pathogens are recognized causing leaf spots on Sansevieria spp., such as Chaetomella sp. (Li et al 2013), Stemphylium lycopersici (Kee et al 2017a), S. vesicarium (Ahmadpour and Poursafar 2018), Neoscytalidium dimidiatum (Kee et al 2017b;Monteles et al 2020), Lasiodiplodia spp. (Kee et al 2019), Curvularia spp.…”
