Fusarium sporotrichioides Sherb., Fusarium tricinctum (Corda) Sacc. and Fusarium poae (Peck) Wollenw. — Cultural Characteristics, Toxinogenicity and Pathogenicity Towards Cereals

Abstract

Taxonomy, toxinogenicity and pathogenicity of 26 isolates of Fusarium‐Sporotricbiella section were studied. Strains of Fusarium sporotrichioides Sherb. isolated in Poland from cereals have been found severely pathogenic towards cereal seedlings. They produced significant amounts of T‐2 toxin (up to 600 mg/kg) and other trichothecenes under laboratory conditions. The investigated strains of F. tricinctum (Corda) Sacc. and F. poae (Peck) Wollenw. proved to be nonpathogenic and nontoxigenic under the same conditions. Zusammenfassung Fusarium sporotrichoides Sherb., F. tricinctum (Corda) Saco und F. poae (Peck) Wollenw. — Kulturmerkmale, Toxinogenität und Pathogenität gegenüber Getreide Untersucht wurde die Taxonomie, Toxinogenität und Pathogenität von 26 Fusarium‐lsolaten aus der Sporotrichiella‐Sektion. Fusarium sporotnchoides‐Sümme, die von Getreide in Polen isoliert wurden, zeigten sich als sehr pathogen gegenüber Getreidesämlingen. Unter Laborbedingungen produzierten diese Stämme bedeutende Mengen an T‐2 Toxin (bis zu 600 mg/kg) und anderen Trichothecenen. Die untersuchten F. tricinctum‐ und F. poae‐Sämme zeigten sich unter den gleichen Bedingungen als nicht pathogen und nicht toxinogen.

Reaction of triticale, wheat and rye accessions to graminaceous Fusarium spp. infection at the seedling and adult plant growth stages

“…On the other hand E crookwellense showed relatively low pathogenicity to the cereals under study, in contrast to findings of Che/kowski et al (1988a) and Mafika (1989). E tricinctum referred as not pathogenic to cereal seedlings (Che/kowski et al, 1989;Marika, 1989) in our studies was found as a medium and/or weakly pathogenic, respectively. Mesterhazy (1987) stated that the cereal resistance to E culmorum and E graminearum should be considered at the genus and not at the species level, since the species specific resistance seems not to exist.…”

“…E nivale) and E graminearum. Many other Fusarium species were isolated from diseased heads and kernels (Lacicowa, 1980;grobarova & Va~kova, 1987;Che/kowski et al, 1988b;Wilcoxson et al, 1988;Che/kowski, 1989;Adler et al, 1990;Arseniuk et al, 1991a, b).…”

First confirmed report on Fusarium sporotrichioides on Pinus ponderosa var. jeffreyi in Slovakia

“…Apical cell is curved and pointed, basal cell is notched or foot-shaped. The fungus is compared with taxonomically related species, which show the presence of polyphialides that produce pyriform as well as fusiform microconidia and blastospores (Chelkowski et al 1989). An important feature for their distinction from other fusaria is numerous brown and globose chlamydospores, which are thick-walled, filled with lipid-like material serving to carry the fungus over winter in soil when no suitable host is available.…”
