“…Amongst plants of the Lauraceae, N. parvum has been reported infecting Persea americana, Cinnamomum camphora, Phoebe sheareri and P. zhennan as reported in Australia, Italy and China (Chen et al, 2019;Sakalidis et al, 2013;Tan et al, 2018;Zhu et al, 2019). This study was the first to show that Chinese cinnamon is one of the many economically important forest hosts that are affected by N. parvum in China; further surveys should be performed in the main Chinese cinnamon-producing countries, such as Vietnam, Sri Lanka and Indonesia (Vu et al, 2020), to confirm the role of this pathogen on the production of Chinese cinnamon.…”

Leaf spot, caused by Neofusicoccum parvum, is an important disease limiting the growth of Chinese cinnamon (Cinnamomum cassia) in the field. This disease was first observed in Deqing (Guangdong Province, China) in 2018, manifesting as circular or irregularly shaped necrotic lesions along the leaf margins and tips, enlarging to irregular lesions with numerous black dots. Representative isolates were isolated from affected leaves and identified based on morphological characteristics and phylogenetic analyses of the internal transcribed spacer (ITS) region, the translation elongation factor 1α (EF1α) gene and a portion of the β-tubulin gene (TUB2). Colonies were initially white on PDA, turning grey-black after 7 days. The conidia were fusiform to oval, hyaline, thinwalled with rounded apices and truncate bases. The pathogen was placed in the same clade as Neofusicoccum parvum in phylogenetic trees constructed using concatenated sequences of ITS, EF1α and TUB2 genes. Based on morphological and phylogenetic data, the pathogen was identified as N. parvum. On infected leaves, Koch's postulates were fulfilled, and the same pathogen re-isolated. To our knowledge, this is the first report of N. parvum causing disease on Chinese cinnamon worldwide.

The EFSA Plant Health Panel performed a pest categorisation of Lasiodiplodia pseudotheobromae, a clearly defined fungus of the family Botryosphaeriaceae, which was first described in 2008 as a cryptic species within the L. theobromae complex. The pathogen affects a wide range of woody perennial crops and ornamental plants causing root rot, damping‐off, leaf spots, twig blight, cankers, stem‐end rot, gummosis, branch dieback and pre‐ and post‐harvest fruit rots. Lasiodiplodia pseudotheobromae is present in Africa, Asia, North and South America and Oceania and has also been reported from Spain with a restricted distribution. However, there is uncertainty on the status of the pathogen worldwide and in the EU because in the past, when molecular tools (particularly multigene phylogenetic analysis) were not available, the pathogen might have been misidentified as L. theobromae. Lasiodiplodia pseudotheobromae is not included in Commission Implementing Regulation (EU) 2019/2072 and there are no interceptions in the EU. Because of the very wide host range of the pathogen, this pest categorisation focused on those hosts for which there is robust evidence that the pathogen was formally identified by a combination of morphology, pathogenicity and multilocus sequence analysis. Plants for planting, including seeds, fresh fruits and bark and wood of host plants as well as soil and other plant‐growing media are the main pathways for the further entry of the pathogen into the EU. Host availability and climate suitability factors occurring in parts of the EU are favourable for the further establishment of the pathogen. In the area of its present distribution, including Spain, the pathogen has a direct impact on cultivated hosts. multilocus measures are available to prevent the further introduction and spread of the pathogen into the EU. Lasiodiplodia pseudotheobromae satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest.
