Double-stranded RNA mycoviruses in Septoria tritici
Mycological Research, 1990Twelve conidial Septoria tritici isolates from different geographical origins were examined for the presence of mycoviruses. Isolates ISR398 (Israel) and ETH8205 (Ethiopia) contained double-stranded (ds) RNA viruses. The genome of these viruses is typified by one dsRNA segment with an apparent molecular weight of 1·3 × 10 6 .

Maintenance of virulence of Septoria tritici cultures
Mycological Research, 1989A technique is described for the production of mature pycnidia of Septoria tritici on wheat leaf extract medium. When two cultures of S. tritici from Israel, reisolated from 1 yr-old pycnidia, were produced on this medium, they maintained their virulence on a differential cultivar set. Long-term preservation of virulence of cultures was possible in

SIMSEPT – ein neues Prognosemodell zum Auftreten von Septoria tritici und Septoria nodorum
Gesunde Pflanzen, 2003SIMSEPT ist ein neues Simulationsmodell zur Vorhersage des Auftretens von Septoria tritici und Septoria nodorum in Winterweizen. Es wurde im Auftrag der Zentralstelle der Pflanzenschutzdienste fur Entscheidungshilfen und Programme (ZEPP) entwickelt und soll die Pflanzenschutzdienste der Bundeslander in ihrer operativen Arbeit (Warndienst) unterstutzen.

Breeding Wheat for Resistance to Septoria nodorum and Septoria tritici
1990Publisher Summary There are three recognized Septoria diseases of wheat, each characterized by its causal fungus. On a worldwide basis, the two most important are septoria nodorum blotch (SNB) and septoria tritici blotch (STB). The third, septoria avenae blotch, is found infrequently and is generally considered a minor disease.

First Report of Zymoseptoria tritici Causing Septoria tritici Blotch in Wheat in Paraguay
Plant Disease, 2023Wheat (Triticum aestivum) is the third most cultivated field crop in Paraguay; it is grown on over 450,000 hectares with an annual production of 927,776 tons (fao.org/faostat). In 1952, Septoria tritici blotch (STB) was associated with the fungus Septoria tritici solely based on microscopic observation of conidia (Viedma and Delgado 1987).

Instant Insights: Septoria tritici blotch in cereals
2022This collection features four peer-reviewed reviews of septoria tritici blotch in cereals. The first chapter reviews the various methods for managing septoria tritici blotch (STB), from the the use of fungicides to marker-assisted breeding for increased resistance to STB. It also surveys research on the molecular basis of host-pathogen interactions in

Chromosome length polymorphisms in a Septoria tritici population
Current Genetics, 1991Transverse alternating field electrophoresis (TAFE) was used to compare the electrophoretic karyotypes of seven Septoria tritici isolates sampled from a single population. Isolates were selected based on differences at 12 DNA restriction fragment length polymorphism (RFLP) loci.

In vitro production of pycnidia by Septoria tritici
Netherlands Journal of Plant Pathology, 1991The in vitro production of pycnidia bySeptoria tritici was examined on six media reported to induce the formation of fruiting bodies. Among 26 freshly isolated cultures from various parts of the world, consistent differences in growth type were found which were only partially influenced by nutritional and environmental conditions.

Winter wheat septoria blotch (Zymoseptoria tritici) (literature review)
2021Dans le district fédéral du Sud, le blé d'hiver est l'une des principales cultures vivrières. L'un des facteurs les plus importants qui peuvent déstabiliser les rendements céréaliers bruts et réduire la productivité des cultures céréalières sont les organismes parasites.
