“…Consequently, pathogenicity test result revealed that C. capsici, C. coccodes, C. lunata, F. oxysporum, M. phaseolina, L. theobromae and P. palmarum were not pathogenic on A. floribunda leaves. Many workers have also reported non pathogenicity of these organisms on various plant species (Arrhenius and Langenheim, 1986;Sanchez Hernadez et al, 1998;Slippers and Wingfield, 2007;Dania et al, 2010;Bagwari et al, 2014). These organisms may not be pathogenic under artificial conditions (seedling inoculation) because potted plants receive different levels of fertilization and moisture (Wingfield, 1996), this finding also corroborate previous results that, greenhouse trials have a moderate to weak correlation with those obtained from the field.…”

Cross-inoculation studies of fifteen Pestalotiopsis isolates collected from different hosts and locations revealed that the fungus is a non specific pathogen. Isolates were able to attack apple, avocado, date-palm, guava, mango and pomegranate causing leaf spot and fruit rot. Disease severity and disease symptoms varied according to plant species. Guava plants was the most susceptible host, all being attacked by tested isolates resulting in brown leaf spot followed by pomegranate, while date palm was least affected. Avocado isolate (P6) was more aggressive on all tested plants, while date palm isolate (P12) was weakest. Six primers were used to determine the degrees of similarity among the tested isolates through RAPD -PCR. Isolates from the same host were not phylogenetically close -related. A close phylogenetic relationship among isolates possessing similar morphological characters was observed.

Following an EFSA commodity risk assessment of bonsai plants (Pinus parviflora grafted on Pinus thunbergii) imported from China, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis microspora, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae. The pathogen was reported on a wide range of monocotyledonous, dicotyledonous and gymnosperms, either cultivated or wild plant species, causing various symptoms such as leaf spot, leaf blight, scabby canker, fruit spot, pre-and post-harvest fruit rot and root rot. In addition, the fungus was reported as an endophyte on a wide range of asymptomatic plant species. This pest categorisation focuses on the hosts that are relevant for the EU and for which there is robust evidence that the pathogen was formally identified by a combination of morphology, pathogenicity and multilocus sequencing analyses. Pestalotiopsis microspora was reported in Africa, North, Central and South America, Asia and Oceania. In the EU, it was reported in the Netherlands. There is a key uncertainty on the geographical distribution of P. microspora worldwide and in the EU, because of the endophytic nature of the fungus, the lack of surveys, and because in the past, when molecular tools were not fully developed, the pathogen might have been misidentified as other Pestalotiopsis species or other members of the Pestalodiopsidaceae family based on morphology and pathogenicity tests. Pestalotiopsis microspora is not included in Commission Implementing Regulation (EU) 2019/2072. Plants for planting, fresh fruits, bark and wood of host plants as well as soil and other growing media associated with plant debris are the main pathways for the entry of the pathogen into the EU. Host availability and climate suitability in parts of the EU are favourable for the establishment and spread of the pathogen. The introduction and spread of the pathogen into the EU are expected to have an economic and environmental impact where susceptible hosts are grown. Phytosanitary measures are available to prevent the introduction and spread of the pathogen into the EU. Unless the restricted distribution in the EU is disproven, Pestalotiopsis microspora satisfies all the criteria that are within the remit of EFSA to assess for this species to be regarded as potential Union quarantine pest.
