“…Besides, this host–pathogen relationship was reported in several other countries, such as Australia (Aldaoud et al 2011), India (Gautam et al 2012), Korea (Park et al 2013) and Iran (Karimi et al 2017). Anthracnose even greatly impacted Sansevieria productions in South Florida when the disease spread in several nurseries until the producers stopped growing the plants (Campoverde and Palmateer 2012).…”

Aims: To characterize causal pathogen of Sansevieria trifasciata anthracnose through morphology and molecular analysis; to evaluate the host range of the pathogen; and to explicate the infection process by the pathogen histopathologically. Methods and Results: Symptomatic leaves of S. trifasciata were collected from five states in Malaysia. The causal pathogen was isolated and identified for the first time in Malaysia as C. sansevieriae based on morphological and multigene phylogenetic analyses using ITS, TUB2 and GAPDH sequences. Pathogenicity tests were conducted on different hosts. Colletotrichum sansevieriae was not pathogenic towards S. cylindrica, S. masoniana, Furcraea foetida, Chlorophytum comosum, Aloe vera and Gasteria carinata, confirming the exceptionally high host specificity for a species of Colletotrichum. Histopathology was performed using light microscope and scanning electron microscopy to study the infection process of C. sansevieriae on S. trifasciata. Colonization of host leaves by the pathogen was observed 2 days after inoculation. Conclusions: Colletotrichum sansevieriae caused anthracnose of S. trifasciata in Malaysia. It is a host-specific pathogen and colonized the host intracellularly. Significance and Impact of the Study: This is the first report of C. sansevieriae causing anthracnose of S. trifasciata in Malaysia. The host range test and understanding of the infection process will provide better understanding of the host-pathogen relationship and beneficial for effective disease management.

En el sur de la Florida, EE.UU, algunos viveros han dejado de importar la planta debido a la enfermedad, a pesar de que la producción de sansevierias ha sido rentable durante muchos años (Campoverde y Palmateer, 2013).…”

“…Algunas especies de Sansevieria han mostrado tolerancia al patógeno, incluidas algunas variedades de la especie S. trifasciata (Pérez-León et al, 2013). Sin embargo, las variedades con mayor demanda en el mercado son susceptibles (Nakamura et al, 2006;Aldaoud et al, 2011;Pérez et al, 2013), por lo que el control químico de la enfermedad es por el momento la opción más viable para su manejo.…”

RESUMENCombate químico de la antracnosis de Sansevieria trifasciata var. Hahnii en un sistema de hojas separadas. El objetivo de este trabajo fue evaluar fungicidas para el combate de antracnosis en Sansevieria trifasciata var. Hahnii. Se evaluaron doce fungicidas (solos o en mezcla) sobre la infección y severidad de C. sansevieriae en un sistema de hojas separadas. Los fungicidas utilizados fueron azoxistrobina, boscalid + piraclostrobina, carbendazina + mancozeb, difenoconazol, epoxiconazol + carbendazina, folpet, imazalil, metil tiofanato + mancozeb, miclobutanil y prochloraz. El estudio se llevó a cabo en el Laboratorio de Biotecnología de Plantas del Centro de Investigaciones Agronómicas, Universidad de Costa Rica, durante el primer semestre del año 2012. La aplicación de los tratamientos se realizó por aspersión el día de la inoculación o tres días después de esta (0 y 3 ddi). A los siete, once y quince días después de la inoculación se evaluó el número y diámetro de las lesiones. El fungicida, el momento de aplicación, la interacción fungicida x momento de aplicación y la interacción fungicida x día de evaluación afectaron significativamente (p<0,0001) las variables evaluadas. Azoxistrobina, boscalid + piraclostrobina, carbendazina + mancozeb, epoxiconazol + carbendazina y metil tiofanato + mancozeb proveyeron un 100% de protección de las hojas de Sansevieria durante todo el período de evaluación (quince días), cuando se aplicaron el mismo día de la inocualción (0 ddi). A los 3 ddi, solo epoxiconazol + carbendazina inhibió en un 100% el establecimiento del patógeno (incidencia cero), en las tres evaluaciones. Con los tratamientos azoxistrobina y carbendazina + mancozeb también se obtuvo un 0% de incidencia a los siete y once días de evaluación para el primero y a los siete días para el segundo.Palabras clave: Lengua de suegra, Colletotrichum sansevieriae, fungicidas para C. sansevieriae. ABSTRACTChemical control of anthrachnose of Sansevieria trisfasciata var. Hahnii on a detached-leaf system. The objective of this work was to assess fungicides to combat Sansevieria trifasciata var. Hahnii anthracnose. Twelve fungicides (alone or in mixture) were evaluated on the infection and severity of C. sansevieriae on a detached-leaf system. Fungicides used were azoxystrobin, boscalid + pyraclostrobin, carbendazim + mancozeb, difenoconazole, epoxiconazole + carbendazim, folpet, imazalil, thiophanatemethyl + mancozeb, myclobutanil, and prochloraz. The study was carried out at the Plant Biotechnology Laboratory of the Agricultural Research Center of the University of Costa Rica, during the first semester of 2012. Each chemical treatment was applied by aspersion on the day of inoculation (0 dai) or three days after it (3 dai). The number and diameter of the lesions were evaluated after seven, eleven and fifteen dai. Fungicide, application moment, fungicide x application moment interaction and fungicide x evaluation moment interaction significantly affected (p<0,0001) both evaluated variables. Azoxystrobin, boscalid + p...

“…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).…”

Leaf spot disease was detected on Sansevieria trifasciata in Malaysia. Two Curvularia species namely C. eragrostidis and C. asianensis were isolated as the pathogens. The isolated fungi were identified based on morphology and multigene phylogeny (ITS, GAPDH and TEF1‐α). Pathogenicity tests confirmed the roles of both Curvularia isolates in causing leaf spot of S. trifasciata. To our knowledge, this is the first report of C. eragrostidis and C. asianensis causing leaf spot of S. trifasciata in Malaysia.
