“…On the other hand it could be the host vigor at the infection time appears to be a determined factor to induce canker and sooty stem in trees. Our data were in agreement with several studies that confirmed the broad host range of the pathogen to cause infection in different trees including; peaches, grapes, cassava, citrus, ficus, palm and melon (Namsi, 2010;Al-Saadoon, 2012;Machado et al, 2014;Mayorquin et al 2016;Rahiminiya et al, 2018;Mirtalebi et al, 2019).…”

The study was conducted at the College of Agricultural Engineering Sciences-Department of Plant Protection in 2018-2019 Baghdad/Iraq. The research aims to molecular identification of the fungal pathogen Neoscytalidium sp. the causal agent of the wilt branches disease on pomegranate, mulberry, apple, castor, and rubber by 18S ribosomal RNA gene and DNA sequencing, to demonstrate the pathogenicity, and host range of the fungal isolates. Five fungal isolates have been recoverd from the infected branches belonged to the five types of trees such as; apple (Malus domestica), pomegranate (Punica granatum), mulberry (Morus alba), india rubber (Ficus elastica), castor (Ricinus communis). The results showed compatibility of 100% with a standard in Gene Bank from Neoscytalidium novaehollandiae in pomegranate, mulberry, apple, and rubber, while in Castor having nine Trinsvertion C>G, A>T, T>G, T>G, G>C, T>G, A>C, A>T, and T>A, and five Transition G>A, G>A, A>G, A>G, and G>A) having 97% compatibility with standard in Gene Bank .This is the first record of the pathogen , N. novaehollandiae on these host trees in Iraq. The pathogenicity test confirmed their ability to infected all types of trees with different symptoms were observed, the results also, showed difference in infection severity which was found to be higher on the apple trees(88.09%).This result indicates the more susceptibility of apple trees to fangal sooty stem disease compared to other trees.

“…However, Mirtalebi et al. ( 2019 ) showed that chains of N. dimidiatum phragmospores were also formed on the surface of artificially inoculated melon, cantaloupe, tomato and watermelon fruits and assumed that they could potentially be disseminated by wind. Similarly, Alizadeh et al.…”

“…However, the results of the study conducted by Mirtalebi et al. ( 2019 ) suggested that the pathogen (as N. hyalinum ) may be transmitted by seeds, as it moved from artificially inoculated melon, cantaloupe, tomato and watermelon fruits to the seed coats.…”

“…N. dimidiatum and other fungi of the family Botryosphaeriaceae have been shown to be seed‐transmitted (Mirtalebi et al., 2019 ). Although there is no evidence so far of N. dimidiatum being transmitted from the seeds to the emerging seedlings, seeds of host plants are likely to be a pathway of further entry of the pathogen into the EU.…”

“…Mirtalebi et al. ( 2019 ) demonstrated that the pathogen can colonise the seed coat. Nevertheless, it has not been studied so far if N. dimidiatum could potentially spread via the seeds of its host plants.…”

The EFSA Plant Health Panel performed a pest categorisation of Neoscytalidium dimidiatum, a clearly defined plant pathogenic fungus of the family Botryosphaeriaceae. The pathogen affects a wide range of woody perennial crops and ornamental plants causing symptoms such as leaf spot, shoot blight, branch dieback, canker, pre-and post-harvest fruit rot, gummosis and root rot. The pathogen is present in Africa, Asia, North and South America, and Oceania. It has also been reported from Greece, Cyprus and Italy, with a restricted distribution. Nevertheless, there is a key uncertainty on the geographical distribution of N. dimidiatum worldwide and in the EU, because in the past, when molecular tools were not available, the two synanamorphs of the pathogen (Fusicoccum-like and Scytalidium-like) might have been misidentified based only on morphology and pathogenicity tests. N. dimidiatum is not included in Commission Implementing Regulation (EU) 2019/2072. Because of the wide host range of the pathogen, this pest categorisation focuses 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, 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 areas of its present distribution, including Italy, the pathogen has a direct impact on cultivated hosts. Phytosanitary measures are available to prevent the further introduction and spread of the pathogen into the EU. N. dimidiatum satisfies the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest.
