“…N. dimidiatum has already been found in a wide variety of woody plants all over the world (Punithalingam & Waterston 1970;Sutton & Dyko 1989;Crous et al 2006). N. dimidatum causes diseases in several plant species, including apricot tree decline in Tunisia (Namsi et al 2010), olive twigs and branch die back in California (Úrbez-Torres et al 2013), ficus canker in Egypt (Al-Bedak et al 2018), root rot of sweet potato in Brazil (Mello et al 2019), pine shoot and needle blight in Turkey (Turkolmez et al 2019), dragon canker in China (Xu et al 2018), and citrus shoot blight in Jordan (Alananbeh et al 2020). The N. dimidiatum infection process includes the formulation of an appressorium, direct cuticle penetration, and colonization of the underlying epidermal cell.…”

Eucalyptus belongs to the Myrtaceae family and has become the main source of different industrial applications such as the production of paper, furniture, energy, charcoal, and housing in the last century. The Eucalyptus genus includes about 700 species (Brooker 2000). Several Eucalyptus species are planted in Iraq; however, the most common species are E. microtheca Muell and E. calmaldulensis Dehn (Al-Iryani 1998). Botryosphaeriaceae, a fam-ily of sac fungi (Ascomycetes), is the typical representative of Botryosphaeriales order. The fungi of this family are usually connected with cankers and dieback in shrubs and woody plants (Bush 2018). According to Crous et al. (2006), the genus Neoscytalidium is a genus of plant pathogenic fungus causing cankers and dieback on woody plants all over the world. In Kurdistan region, several symptoms have been observed in the eucalyptus

“…N. dimidatum causes diseases in several plant species: canker of Ficus trees in Egypt [24]; root rot of sweet potato in Brazil [25]; shoot and needle blight of pines (Pinus spp.) in Turkey [26]; and shoot blight of citrus in Jordan [27]. Furthermore, N. dimidiatum has also been reported to cause canker on H. polyrhizus in Taiwan [28], Malaysia [3], and China [29].…”

Red-fleshed dragon fruit (Hylocereus polyrhizus) is commonly cultivated in Thailand, especially in southern Thailand, where the weather favors plant growth and development. In 2021, stem canker of H. polyrhizus was observed in a dragon fruit plantation field in Phatthalung Province, southern Thailand. Small, orange circular spots developed on the stem of H. polyrhizus, which later became gray, and the lesion expanded with a mass of conidia. Scytalidium-like fungus was isolated from infected tissues. Based on morphology and phylogenetic analyses of internal transcribed spacer (ITS), nuclear large subunit (LSU) and β-tubulin (tub) sequences of fungal isolates, the fungus was identified as Neoscytalidium dimidiatum. Pathogenicity tests revealed that this isolate caused stem canker on the stem of H. polyrhizus, similar to that observed in the field. Knowledge of the diagnosis of plant diseases is an important step for managing plant diseases and therefore, this finding provides basic information for the development of appropriate strategies to manage stem canker disease on H. polyrhizus plants.

The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers the plant health risks posed by the following commodities: i) dormant and free of leaves 1‐year‐old bare rooted plants and ii) free of leaves 1‐year‐old liners of Ficus carica imported from Israel, taking into account the available scientific information, including the technical information provided by Israel. The relevance of any pest for this opinion was based on evidence following defined criteria. Four EU quarantine pests, Euwallacea fornicatus, Hypothenemus leprieuri, Scirtothrips dorsalis and Spodoptera frugiperda, and 11 EU non‐regulated pests fulfilled all relevant criteria and were selected for further evaluation. For these pests, the risk mitigation measures proposed in the technical dossier from Israel were evaluated separately for bare rooted plants and for liners, taking into account the possible limiting factors. For these pests, an expert judgement was given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. The estimated degree of pest freedom varied among the pests evaluated. Aonidiella orientalis and Russellaspis pustulans were the most frequently expected pests on the imported bare rooted plants, and Scirtothrips dorsalis on liners. The Expert Knowledge Elicitation indicated, with 95% certainty, that between 9,585 and 10,000 bare rooted plants per 10,000 would be free of Aonidiella orientalis and Russellaspis pustulans and between 9,456 and 10,000 liners per 10,000 would be free of Scirtothrips dorsalis.
