Alocasia longiloba is a popular ornamental plant in China, however pests and diseases associated with A. longiloba reduce the ornamental value of this plant. From 2016 to 2021, stem and root rot has been observed on A. longiloba in Guangdong Province, China. Once the disease became severe, plants wilted and died. A fungus was isolated from the diseased stem and identified as Fusarium elaeidis using both morphological characteristics and molecular analysis of DNA-directed RNA polymerase II subunit (rpb2), translation elongation factor-1α (tef1) gene and β-tubulin (tub2) sequence data. The pathogenicity test showed the fungus was able to produce typical symptoms on A. longiloba similar to those observed in the field. The original pathogen was reisolated from inoculated plants fulfilling Koch’s postulates. This is the first report of Fusarium elaeidis causing stem rot on A. longiloba. These results will provide a baseline to identify and control diseases associated with A. longiloba.

“…Fusarium is one of the most devastating pathogens on numerous agronomic, forestry, and horticultural crops worldwide ( Wang et al, 2022 ). Therefore, correct species delineation is crucial for sustainable disease control of these pathogens ( Jayawardena et al, 2021 ; Manawasinghe et al, 2021 ). Crous et al (2021) re-examined the fusarioid taxa in Nectriaceae and showed that the Wollenweber concept of Fusarium presently encompasses 20 distinct genera.…”

“…With the rapid development of the ornamental plant industry, diseases have become an emerging problem that affects plant production. It is necessary to identify pathogens for early detection and control, especially in commercial nurseries where several plant generations will be established within a controlled environment ( Jayawardena et al, 2021 ; Manawasinghe et al, 2021 ).…”

Aglaonema modestum (A. modestum) (Araceae) is an evergreen herbage, which is intensively grown as an ornamental plant in South China. A new disease was observed in A. modestum from 2020 to 2021 in Guangdong province, China. The disease symptoms associated with plants were initial leaf wilt, stem rot, and resulting plant death, leading to severe economic losses. In total, six Fusarium isolates were obtained from diseased plants. The putative pathogen was identified using both morphological characteristics and molecular phylogenetic analysis of calmodulin A (cmdA), RNA polymerase largest subunit 1 (rpb1), RNA polymerase II (rpb2), translation elongation factor-1α (tef1-α), and beta-tubulin (β-tubulin) sequences. Two Fusarium species were identified, namely, one new species, Fusarium aglaonematis (F. aglaonematis) belonging to Fusarium fujikuroi species complex. In addition, Fusarium elaeidis (F. elaeidis) belonging to the Fusarium oxysporum (F. oxysporum) species complex was also identified. Pathogenicity assays were conducted by inoculating each species into potted A. modestum plants and co-inoculating two species. The results showed that two Fusarium species could infect plants independently and can infect them together. Co-infection of these two species enhanced the disease severity of A. modestum. Compared to single inoculation of F. elaeidis, severity was higher and disease development was quicker when plants were only inoculated with F. aglaonematis. In addition, these two Fusarium species could infect Aglaonema plants without wounds, while inoculation with a physical injury increased disease severity. This is the first report of co-infection by F. aglaonematis and F. elaeidis causing stem rot on A. modestum worldwide. This study will be an addition to the knowledge of Fusarium diseases in ornamental plants. These results will provide a baseline to identify and control diseases associated with A. modestum.

Pogostemon cablin is one of the well-known Southern Chinese medicinal plants with detoxification, anti-bacterial, anti-inflammatory, and other pharmacological functions. Identification and characterization of phytopathogens on P. cablin are of great significance for the prevention and control of diseases. From spring to summer of 2019 and 2020, a leaf spot disease on Pogostemon cablin was observed in Guangdong Province, South China. The pathogen was isolated and identified based on both morphological and DNA molecular approaches. The molecular identification was conducted using multi-gene sequence analysis of large subunit (LSU), the nuclear ribosomal internal transcribed spacer (ITS), beta-tubulin (β-tubulin), and RNA polymerase II (rpb2) genes. The causal organism was identified as Stagonosporopsis pogostemonis, a novel fungal species. Pathogenicity of Stagonosporopsis pogostemonis on P. cablin was fulfilled via confining the Koch's postulates, causing leaf spots and stem blight disease. This is the first report of leaf spot diseases on P. cablin caused by Stagonosporopsis species worldwide.
