CO OZNACZA SŁOWO WHEAT RUST
Rdza liści pszenicy
Rdza z liści pszenicy jest chorobą grzybową, która dotyka łodyg pszenicy, jęczmienia i żyta, liści i ziaren. W strefach umiarkowanych destrukcyjne jest pszenica ozimej, ponieważ patogen jest nadmierny. Zakażenia mogą prowadzić do utraty 20% plonów - zaostrzone przez umieranie liści, które zapłodniają grzyby. Patogenem jest grzyb rdzawski Puccinia. Puccinia triticina powoduje czarną rdzę, P.recondita powoduje brązową rdzę, a P.striiformis powoduje żółtą rdę. Jest to najbardziej rozpowszechniona ze wszystkich chorób rdzy pszenicy, występujących w większości regionów uprawy pszenicy. Powoduje poważne epidemie w Ameryce Północnej, Meksyku i Ameryce Południowej i jest niszczącą sezonową chorobą w Indiach. Wszystkie trzy rodzaje Puccinia są heteroecious wymagające dwóch odrębnych i daleko spokrewnionych gospodarzy. Rdza i podobny smut są członkami klasy Pucciniomycetes, ale rdza nie jest normalnie czarną proszkową masą.
