Beispiel I Weizenpflanzen werden im 3-Blattstadium mit Konidien des Weizenmehltaus (Erysiphe graminis) stark inokuliert und in einem Gewächshaus bei 200C und einer relativen Luftfeuchte von 90 - 95 % aufgestellt. 3 Tage nach Inokulation werden die Pflanzen mit den in Tabelle I aufgeführten Verbindungen in den Wirkstoffkonzentrationen von 500, 250, 125, 60 und 30 mg/Liter Spritzbrühe tropfnaß gespritzt. Als Vergleich wird das Vergleichsmittel B in analoger Weise eingesetzt. Example I Wheat plants are grown in the 3-leaf stage with conidia des Wheat powdery mildew (Erysiphe graminis) heavily inoculated and placed in a greenhouse 200C and a relative humidity of 90 - 95%. 3 days after inoculation the plants with the compounds listed in Table I in the active ingredient concentrations 500, 250, 125, 60 and 30 mg / liter spray liquid sprayed to runoff. As comparison the comparison means B is used in an analogous manner.
Nach einer Inkubationszeit von 10 Tagen werden die Pflanzen auf Befall mit Weizenmehltau untersucht. After an incubation period of 10 days, the plants are checked for infestation examined with wheat powdery mildew.
Der Befallsgrad wird ausgedrückt in % befallener Blattfläche, bezogen auf unbehandelte, infizierte Kontrollpflanzen (= 100 % Befall). Das Ergebnis ist in der Tabelle I zusammengefaßt. The degree of infestation is expressed as a percentage of the infested leaf area on untreated, infected control plants (= 100% infestation). The result is summarized in Table I.

Der Befallsgrad wird ausgedrückt in % befallener Blattfläche, bezogen auf unbehandelte, infizierte Kontrollpflanzen (= 100 % Befall).The assessment takes place after 10 days. The degree of infestation is expressed in% infected leaf area, based on untreated, infected control plants (= 100% infestation).
Das Ergebnis ist in der Tabelle IV zusammengefaßt.The result is summarized in Table IV.
