Pest categorisation of Fusarium pseudograminearum
EFSA Journal. European Food Safety Authority
|July 5, 2022
Summary
Fusarium pseudograminearum causes Fusarium crown rot and head blight in cereals and has been reported outside the EU. This soil-borne pathogen could establish in the EU, posing a potential quarantine pest risk.
Area of Science:
- Plant pathology
- Mycology
- Agricultural entomology
Background:
- Fusarium pseudograminearum is a soil-borne fungal pathogen causing Fusarium crown rot and head blight in small grain cereals.
- It also affects soybean and various grass species, serving as potential inoculum reservoirs.
- The pathogen is prevalent in arid/semi-arid regions globally and has been reported in Italy and Spain within the EU.
Purpose of the Study:
- To perform a pest categorisation of Fusarium pseudograminearum for the EFSA Plant Health Panel.
- To assess the risk of Fusarium pseudograminearum establishing and spreading within the European Union.
- To determine if Fusarium pseudograminearum meets the criteria for a Union quarantine pest.
Main Methods:
- Review of scientific literature and databases on Fusarium pseudograminearum distribution, hosts, and impact.
- Analysis of pathways for introduction and spread, including seeds, soil, and plant debris.
- Assessment of EU host availability and climate suitability for pathogen establishment.
Main Results:
- Fusarium pseudograminearum has a wide geographic distribution outside the EU, impacting key crops like wheat and barley.
- While reported in Italy and Spain, its full distribution in the EU is uncertain.
- EU's host availability and climate conditions are favorable for pathogen establishment.
- No interceptions of the pathogen have been recorded in the EU, but phytosanitary measures exist.
Conclusions:
- Fusarium pseudograminearum satisfies the criteria to be considered a potential Union quarantine pest.
- The pathogen poses a risk to EU agriculture due to its impact on relevant crops in other regions.
- Phytosanitary measures are crucial for preventing introduction and mitigating spread within the EU.

Phylum Ascomycota, a major division within the subkingdom Dikarya, comprises a diverse range of fungal species, including both unicellular yeasts and filamentous molds such as Aspergillus and Penicillium. These fungi thrive in a variety of habitats, from aquatic ecosystems to terrestrial environments, playing crucial ecological and economic roles.Morphology and ReproductionThe defining characteristic of Ascomycetes, commonly referred to as sac fungi, is the ascus—a sac-like structure that...

Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Planctomycetes are a group of morphologically distinct bacteria predominantly classified into two orders: Planctomycetales and Brocadiales. These gram-negative bacteria exhibit unique features, including division by budding and the presence of stalks or appendages. Their cells are often found in rosette arrangements, and they are notable for possessing an S-layer in their cell envelope, which is relatively uncommon among bacteria. Additionally, Planctomycetes frequently exhibit intracellular...
