Wheat leaf rust (Puccinia triticina) is a fungal disease that affects wheat, barley, rye stems, leaves and grains. In temperate zones it is destructive on winter wheat because the pathogen overwinters. Infections can lead up to 20% yield loss, which is exacerbated by dying leaves, which fertilize the fungus. The pathogen is a Puccinia rust fungus. It is the most prevalent of all the wheat rust diseases, occurring in most wheat-growing regions. It causes serious epidemics in North America, Mexico and South America and is a devastating seasonal disease in India. P. triticina is heteroecious, requiring two distinct hosts (alternate hosts).

  • صدأ أوراق القمح هو مرض فطري يصيب بعض المحاصيل الزراعية مثل القمح والشيلم. للصدأ سلالات مختلفة تختص بفصائل مختلفة، فالسلالة التي تصيب محاصيل الفصيلة النجيلية هي (باللاتينية: Puccinia graminis tritici) من نوع فطر البوشيني القمحي. (ar)
  • Der Braunrost des Weizens (Puccinia triticina) ist ein Vertreter der Rostpilze (Pucciniales) und ein auch in Mitteleuropa bedeutender Schadpilz an Weizenkulturen. Wie alle Rostpilze ist der Braunrost ein obligater Parasit. (de)

  • Brunrost är en svampsjukdom som drabbar vete, råg och rågvete och kan medföra stora skördeförluster. Mottagligheten varierar mycket mellan olika sorter. Svamparna som orsakar brunrost tillhör släktet Puccinia och familjen Pucciniaceae. Vetebrunrost orsakas av en svamp med det vetenskapliga namnet Puccinia triticina, och brunrost på råg och rågvete orsakas av en svamp med det vetenskapliga namnet Puccinia recondita. Förutom att brunrost medför stora skördeförluster kan sjukdomen även bana väg förandra sjukdomar såsom brunfläcksjuka och svartpricksjuka. (sv)
  • La rouille brune du blé est une maladie cryptogamique qui affecte les feuilles, tiges et grains du blé, de l'orge et du seigle. Dans les zones tempérées, elle est très destructive sur le blé d'hiver du fait que l'agent pathogène hiverne.Les infections peuvent entraîner des pertes de rendement allant jusqu'à 20 %, pertes aggravées par les feuilles mortes qui fertilisent le champignon.L'agent pathogène est un champignon du genre Puccinia, (tandis que est l'agent de la rouille noire et Puccinia striiformis celui de la rouille jaune). C'est la plus répandue de toutes les maladies de rouille du blé, présentes dans la plupart des régions de culture du blé. Elle provoque de graves épidémies notamment en Amérique du Nord, au Mexique et en Amérique du Sud, et c'est une maladie saisonnière dévasta (fr)
