“…F. oxysporum was reported to be the primary agent responsible for potato dry rot amidst 11 species in Michigan, USA (Gachango et al 2012) and South Korea (Kim and Lee 1994). F. avenaceum dominated potato Fusarium population investigated between 1997 and 2000 in Scotland (Choiseul et al 2007), while F. solani var. coeruleum dominated in four regions of Great Britain, including eastern Scotland, in 2000-2002(Peters et al 2008a).…”

Fusarium spp. belong to the division Ascomycota and cause important plant diseases; these fungi may contaminate food products with mycotoxins, endangering human and animal health. Several Fusarium spp. have been associated with potato dry rot. The most frequent and devastating of these species are F. sambucinum, F. solani and F. oxysporum, depending on the geographic location and the season. Samples of potato tubers with dry rot symptoms were collected, and their putative fungal isolates were identified as Fusarium species using partial nucleotide sequences of the internal transcribed spacer, translation elongation factor 1-α and β-tubulin genes. Among 149 isolates, 12 species were identified. F. oxysporum was the most frequent (45 % of the isolates), followed by F. avenaceum (12.1 %), F. solani (10.7 %) and F. sambucinum (7.4 %). Phylogenetic analyses confirmed the species identifications and revealed a high diversity of F. solani and a low diversity of F. oxysporum. Potential producers of zearalenone and trichothecenes were identified within the obtained isolates using PCR markers. Isolates that were pathogenic to potatoes in laboratory tests were found in four species: F. sambucinum, F. avenaceum, F. culmorum, and F. graminearum. The effects of increased temperature and mixed inoculum on the pathogenicities of chosen species were evaluated. This study adds 434 potato-derived Fusarium sequences to the NCBI GenBank database and demonstrates that the list of Fusarium species and mycotoxins present in potato tubers may be richer than previously believed, regardless of whether these species cause dry rot or live as saprophytes.

Microbial communities in roots, rhizoplane, rhizosphere soil and non‐rhizosphere soil in potato were compared in organic and integrated production systems in 2005–2007. Identification of microorganisms was based on morphotyping. The density (number of colony‐forming units in a sample) of Fungi and Oomycota was significantly greater in the integrated system. Greater densities of Arthrobacter and Streptomyces occurred more often in organic and integrated systems, respectively. The dominant fungal taxa (with frequency >5% in at least one habitat) included Aspergillus, Clonostachys + Gliocladium, Colletotrichum coccodes, Fusarium + Gibberella + Haematonectria + Neonectria, Gibellulopsis nigrescens, Paecilomyces, Penicillium, Phoma and Trichoderma. The subdominant taxa (with frequency 1–5%) included species from 16 genera. In the rhizoplane, rhizosphere and non‐rhizosphere soil, the total density of pathogens was greater in the organic system, and of antagonists in the integrated system. Dominant pathogens, that is, C. coccodes, Fusarium culmorum, Haematonectria haematococca and G. nigrescens, and dominant antagonists, that is, Clonostachys + Gliocladium and Trichoderma, occurred at greater density in the organic system. Subdominant pathogens, that is, Alternaria + Ulocladium, Pythium and Thanatephorus cucumeris, and subdominant antagonists, that is, Mortierella and Umbelopsis vinacea, occurred at significantly greater density in the integrated system. Incidence of sprout rot was more frequent in the organic system, and of Fusarium dry rot and black scurf in the integrated system. The organic system provided a less disease‐suppressive environment than the integrated system and resulted in smaller potato yield. An integrated system of potato production based on 4‐year rotation, white mustard as a cover crop, inorganic fertilizers including ammonium nitrate and chemical control of insects and diseases may be promoted in Poland.
