“…6 B. dothidea is a common pathogenic organism in vegetations such as apples, mangoes, and oranges. 7 In this article, we report the first case of human fungal infection by B. dothidea . Our case showed that the clinical course of the infection of B. dothidea was less aggressive, developing slowly over a period of 2 months.…”

Purpose: The aim of this study was to report the first case of mycotic keratitis caused by Botryosphaeria dothidea. Methods: A 29-year-old man developed a fungal infection after being hit with chestnut thorns in the left eye. In vivo confocal microscopy, microbial culture, and next-generation sequencing (NGS) were used in the diagnosis of mycotic keratitis. Results: The patient was provisionally diagnosed with mycotic keratitis based on IVCM and promptly received local and systemic antifungal treatment with voriconazole and amphotericin B. Although microbial culture failed to identify the pathogen, NGS revealed B. dothidea as the causative agent. Although the infection was quickly contained, corneal perforation still occurred. Owing to the lack of fresh donor corneas, the patient underwent multilayer amniotic membrane and conjunctival pedicle graft surgery. The infection was successfully controlled, and during the 6-month follow-up, the cornea remained clear in the inferotemporal optical zone. Conclusions: We report a novel phytopathogen—B. dothidea—causing mycotic keratitis. Our case indicates that B. dothidea responds well to voriconazole and amphotericin therapy. This case broadens the spectrum of fungal keratitis and highlights the application of NGS in identifying molds.

“…The main means of entry into the host are through wounds created by pruning tools, insects and adverse climatic conditions (frost, hail), as well as during harvest, transportation, handling and storage of fruits (Ploetz, 2003 ). Nevertheless, direct penetration of the host tissues by the pathogen with or without the formation of appressoria has also been observed in the case of fruits (Navarro et al., 2022 ). The fungus colonises the vascular system and advances ahead of the visible symptoms (Burgess et al., 2006 ; Shahbaz et al., 2009 ).…”

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.

“…The patho-gens Lasiodiplodia and Fusicoccum/Neofusicoccum were found in early-developing fruits, 0.8 cm long, after disinfestation of the fruits with sodium hypochlorite (5 g/L -1 ) for five minutes and treatment with paraquat (3 g/L -1 ) for a minute (FISCHER et al 2019). Infection in fruits also occurs by lenticels under high humidity conditions, being favored by injuries to the fruit skin (NAVARRO et al 2022).…”

There may be many factors contributing to reduction in longevity and productivity in avocado trees, especially diseases of fungal and fungal-like pathogens, among which Phytophthora root rot, scab, cercospora spot, anthracnose, branch canker and stem-end rot are the most important. Phytophthora root rot is the most important disease of avocado. The pathogen attacks the fine feeder roots of avocado plants and induces multiple symptoms, and, if left untreated, can result in the death of trees and high economic losses. Scab and cercospora spot mainly affect fruit quality and cause fruit drop in intense attacks. Anthracnose and stem-end rot cause severe losses under favorable environmental conditions and the absence of preventive control, occurring mainly in postharvest, during storage and transport of the fruits. Branch canker affects the seedling set and reduces the productivity of the orchard, which can even cause the death of trees in severe attacks. The permanent occurrence of diseases in some areas may turn the crop unprofitable, which requires knowledge and adequate management to obtain productivity and high quality fruits. This review cover the main avocado diseases, their symptoms, etiology, epidemiology and management.
