The EFSA Plant Health Panel performed a pest categorisation of Fusarium brachygibbosum Padwick. F. brachygibbosum is a well-characterised fungal plant pathogen with opportunistic behaviour, mostly isolated along with other fungal pathogens in symptomatic hosts. It has been reported from Africa, America, Asia and Oceania where it is has been associated with a wide range of symptoms on approximately 25 cultivated and non-cultivated plant species. The pathogen has been reported in Italy in soil/marine sediments and in quinoa (Chenopodium quinoa) and durum wheat (Triticum turgidum subsp. durum) seeds. The pathogen is not included in the EU Commission Implementing Regulation 2019/2072. This pest categorisation focused on a selected range of host plant species on which F. brachygibbosum fulfilled Koch 0 s postulates and was formally identified by multilocus gene sequencing analysis. Host plants for planting, seed of host plants and soil and other substrates originating in infested third countries are main pathways for the entry of the pathogen into the EU. There are no reports of interceptions of F. brachygibbosum in the EU. Host availability and climate suitability factors occurring in the EU are favourable for the establishment of the pathogen in Member States (MSs). Phytosanitary measures are available to prevent the introduction of the pathogen into the EU. Additional measures are available to mitigate the risk of entry and spread of the pathogen in the EU. Despite the low aggressiveness observed in some reported hosts, it has been shown that, in the areas of its present distribution, the pathogen has a direct impact on certain hosts (e.g. almond, onion, soybean, tobacco) that are also relevant for the EU. The Panel concludes that F. brachygibbosum satisfies all the criteria to be regarded as a potential Union quarantine pest. However, high uncertainty remains regarding the distribution of the pathogen in the EU and some uncertainty exists about its potential impact in the EU. Specific surveys and re-evaluation of Fusarium isolates in culture collections could reduce these uncertainties.

“…Moreover, wheat heads infected with Fusarium showed bleaching symptoms with dense colonies of whitish mycelium typical for Fusarium species responsible for fusarium head blight (Ghimire et al, 2020). Inoculations of Fusarium species on bread wheat produced ear bleaching symptoms with a fusarium head blight severity of 12.46%, with significant differences between infected varieties (P > 0.05) (Mohammed -Ameen et al, 2021).…”

Morphological and cultural characterization of two Fusarium isolates causing wheat fusarium head blight in Algeria

In Algeria, fusarium head blight is a serious fungal disease of wheat caused by Fusarium genus. The study of the epidemiological cycle of the disease in the field is always hampered by a major problem which is the identification of the parasitic complex of Fusarium species. These species can only be identified after Petri dish culture and observation of a set of morphological criteria such as color, cultural aspect of colonies, growth rate of mycelium and the form of isolate macroconidia. To this end, the objective of this present study is to identify two Fusarium isolates based on a set of morphological and cultural criteria mentioned above. The results obtained for all the morphological characters studied show phenotypic variability between the two isolates. Based on these results, we were able to characterize these two isolates as F. graminearum and F. culmorum. Indeed, morphological and cultural characterization, although important, remains insufficient. It should therefore be further investigated by molecular characterization, in order to highlight any differences between the two isolates studied.

Abstract. Fadhil WF, Al-Saadoon AH, Al-Moussawi FM. 2022. New records of mycobiota associated with stored wheat and its by-products in Iraq. Biodiversitas 23: 3099-3107. Wheat is a staple food for the Iraqi population and is an important feed source due to its high nutritional value. Consequently, wheat and wheat by-products are susceptible to various species of fungi during processing, transportation, or storage. In this paper, thirty-two selected fungal isolates were subjected to morphological and molecular analysis for identification through combined sequences of ITS regions, actin, calmodulin, glyceraldehyde-3-phosphate dehydrogenase, and ?-tubulin genes according to the target fungal genus. The results showed that eighteen fungal species were identified from wheat grains, flour, and bran samples collected from different silos and mills in three provinces in southern Iraq. In addition, nine species were recorded for the first time from Iraq, i.e., Alternaria consortialis, A. japonica, A. lolii, A. multiformis, A. ventricosa, Aspergillus montevidensis, Cladosporium halotolerans, C. versiforme, and Staganosporopsis tanaceti. Brief descriptions of the new records are presented. This study represents an important addition to the mycobiota of Iraq.
