“…Although N. dimidiatum almost infects the woody plants, but there are some reports that this species causes disease on leafy plants. The N. dimidiatum has been reported as the leaf blight causal agent on white spider lily ( Hymenocallis littoralis ) in Malaysia, Cattleya × hybrid in Taiwan, Sansevieria trifasciata in Brazil, Origanum onites and Melissa officinalis in Turkey 18 , 19 , 22 , 68 , 69 . Based on our observation of the surveyed greenhouse, about 16 percent of the growing Clivia plants had the leaf blight symptom, similar to the sampled symptom, showing the importance of the emerging leaf blight disease on Clivia plants caused by N. dimidiatum .…”

In this survey, the symptomatic leaves of Clivia miniata were collected from a greenhouse in Karaj city of Iran. The isolation and morphological investigation showed Scytalidium-like fungus associated with leaf blight symptom. The phylogenetic analysis of the internal transcribed spacer along with partial sequences of rDNA large subunit and translation elongation factor 1-α (tef-1α) genomic regions confirmed the identification of the recovered isolate as Neoscytalidium dimidiatum. The pycnidial morph of the fungus didn’t observe both in vitro and in vivo. The pathogenicity test on C. miniata and C. nobilis was also conducted to fulfill the Koch’s postulates. To our Knowledges, this is the first report of N. dimidiatum causing leaf blight disease on C. miniata and C. nobilis worldwide, as well as these host plants are new for N. dimidiatum in the world.

Este estudo avaliou as atividades anticolinesterásica, antimicrobiana e fungicida do óleo fixo das sementes de araticum (Annona coriacea Mart., família Annonaceae), obtido com etanol como solvente extrator. O óleo fixo foi testado in vitro contra a enzima acetilcolina, cepas bacterianas gram-positivas (Staphylococcus aureus e S. epidermides) e gram-negativas (Escherichia coli e Pseudomonas aeruginosa), e fungos (Candida albicans, C. krusei, Neoscytalidium dimidiatum e Fusarium sacchari). O óleo fixo mostrou-se inibidor da enzima acetilcolinesterase, com inibição variando de 37 a 84%. Foi inativo contra bactérias gram-positivas, gram-negativas e fungos, com MIC ≥1024, através do ensaio antimicrobiano. Permitiu controles de crescimento micelial de N. dimidiatum nas cinco doses testadas (0.1, 0.5, 1.0, 2.0 e 3.0 µL mL-1). Não foi observado controle significativo contra F. sacchari, as doses 1, 2 e 3 (0.1, 0.5 e 1.0 µL mL-1) apresentaram porcentagens baixas de inibição, enquanto as doses 4 e 5 apresentaram controle, entretanto, o mesmo não diferiu do crescimento micelial no tratamento controle com meio de cultura. Pode-se concluir que o óleo fixo das sementes de araticum é um forte candidato ao desenvolvimento de fitofármacos à base de A. coriacea contra fungos patogênicos.

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

Sansevieria species are valued in Europe as potted houseplants because of their modest maintenance requirements and low susceptibility to diseases and pests. Water-soaked leaf spots that eventually coalesced into large, drying lesions were observed on Sansevieria trifasciata freshly imported from Costa Rica. A Colletotrichum was isolated from the fungal fruiting bodies that developed on these necroses. It was confidently determined to be C. sansevieriae based on the host plant and microbiological as well as molecular biology test results. This is the first detection of C. sansevieriae in Germany.
