“…The symptoms on plants and characteristics of the species were similar to those noted in our study. S. rolfsii is also a very dangerous pathogen of orchids as described for the first time by Bag (2004) in the USA, on Cymbidium and its hybrids, and later on Phalaenopsis and Cymbidium in Korea (Han et al 2011(Han et al , 2012. Our studies also confirmed the data of Pane et al (2007) and Han et al (2012).…”

Stem and leaf rot incited by Sclerotium rolfsii was found on Epipremnum aureum, Hedera helix, and Peperomia obtusifolia rooting cuttings. S. rolfsii was isolated from about 90% of the analysed plant materials. Isolate from E. aureum colonized all the parts of the 3 host plants as well as eustoma and lavender. Necrosis spread significantly faster on peperomia and the nonhost plants. The fungus produced dense, floccose, white mycelium with numerous, small, brown sclerotia. The optimum temperature for development was 30°C.

“…The pathogenic fungus produces the virulence factor oxalic acid, which inhibits the host's defenses and causes stomatal opening, ultimately leading to increases transpiration rates and reduced biomass, resulting in wilting (Guimarães and Stotz, 2004;Kabbage et al, 2015). Infected plants of S. rolfsii produce white mycelial mats on the surface of the lesion, which are followed by the formation of globular nuclei either at the infection site or in the surrounding soil (Han et al, 2012;Amaradasa et al, 2020). C. oleifera is predominantly a seedling disease, and infection with S. rolfsii causes lesions to appear near the ground at the base of the stem or at the root base, which indicates a covering of white mycelium and dark-colored pycnidia.…”

Camellia oleifera Abel, a woody oil plant, that is endemic to China. Tea oil, also referred to as “oriental olive oil,” is a superior quality plant-based cooking oil. The production of tea oil accounts for 8% of the total edible vegetable oil production in the country. Since 2022, the annual output value of C. oleifera industry has exceeded 100 billion yuan, making it one of the major economic contributors to China’s rural revitalization development strategy. In recent years, demand and production have grown in parallel. However, this has led to an increase in the incidence levels of pest and diseases. Pests and diseases significantly reduce the quality and yield of C. oleifera. C. oleifera diseases are mainly caused by pathogenic fungi. C. oleifera anthracnose, soft rot, leaf spot, coal stain, leaf gall disease, and root rot are the most important fungal diseases affecting the C. oleifera industry. However, the same disease may be caused by different pathogenic fungi. C. oleifera can be found in half of China and is found in several climatic zones. The geographical distribution of woody plant diseases is consistent with the distribution of the tree species and the ecology of the range, which also results in a highly complex distribution of fungal diseases of C. oleifera. The management of fungal diseases in C. oleifera is extremely challenging due to the variety of pathogenic fungal species, multiple routes of transmission, the lack of resistant plants, and the environmental safety of chemical measures. The optimal strategy for addressing fungal diseases in C. oleifera is to develop and apply an integrated disease management plan. This review provides a brief overview of the pathogenic species, pathogenesis, pathogenesis, geographical distribution, current management strategies, and potentially new methods of C. oleifera fungal diseases, to provide direction for the development of comprehensive management measures for C. oleifera fungal diseases in the future.

Bacterial diseases of Cymbidium orchids continue to threaten the floriculture industry. Bacterial isolates were isolated and cultured from Cymbidium plants exhibiting disease symptoms: black lesions with or without water-soaking on leaves. To identify the bacterial isolates, we performed polymerase chain reaction (PCR) amplification using species-specific primers. The pathogen was tentatively identified as Burkholderia gladioli, which was first described as a phytopathogen, and later associated with human infections, especially with patients with cystic fibrosis. PCR-restriction fragment length polymorphism analysis of 16S ribosomal DNA (rDNA) products digested with HinfI and sequencing of the 16S rDNA confirmed the isolate as B. gladioli. Burkholderia gladioli strains infecting plants are divided into two pathovars: alliicola and gladioli. Pathogenicity tests showed that the isolate proved to be pathogenic to Cymbidium orchid but not to onion plants, a common host for B. gladioli pv. alliicola. To the best of our knowledge, this is the first report of B. gladioli in Cymbidium orchids in Korea.
