Die mungiziden Versuche wurden im Laboratorium (in vitro) und in einem Gewächshaus (in vivo) durchgeführt. Bei den Laborversuchen wurden die Verbindungen in den Boden vermischt, so dass die Konzentration der Chemikalien im Boden 100 ppm beträgt. Die folgenden Pilze wurden im Versuch verwendet: The fungicidal experiments were carried out in the laboratory (in vitro) and in a greenhouse (in vivo). In the laboratory tests, the compounds were mixed into the soil so that the concentration of the chemicals in the soil is 100 ppm. The following mushrooms were used in the experiment:
Botrytis cinerea Fusarium oxysporum Stemphylium radicinum Helminthosporium turcicum Trichothecium roseum Rhizoctonia solani Alternaria tenuis. Botrytis cinerea Fusarium oxysporum Stemphylium radicinum Helminthosporium turcicum Trichothecium roseum Rhizoctonia solani Alternaria tenuis.
Während der in vivo-Versuche wurden die Pflanzen mit einer 1000 ppm Lösung der Verbindungen besprüht und infiziert. Die Versuche wurden mit den folgenden Spezies durchgeführt: During the in vivo experiments, the plants were sprayed with a 1000 ppm solution of the compounds and infected. The experiments were carried out with the following species:
Erysiphe graminis - Weizen Sphaerotheca fuliginea - Gurken Phytophthra infestans - Tomaten Uromyces appendiculatus - Bohnen. Erysiphe graminis - Wheat Sphaerotheca fuliginea - Cucumber Phytophthra infestans - Tomato Uromyces appendiculatus - Beans.
Gegen Erysiphe graminis wurde auch die systemische Wirkung der Verbindungen geprüft. The systemic activity of the compounds was also tested against Erysiphe graminis.
Die fungizide Wirkung wurde in der folgenden Tabelle gezeigt. Der Wirkungsgrad wurde wie folgt bonitiert: The fungicidal activity was shown in the following table. The efficiency was rated as follows:
0 = Hemmung von 0-25 % 0 = 0-25% inhibition
1 = Hemmung von 26-50 % 1 = inhibition of 26-50%
2 = Hemmung von 51-75% 2 = inhibition of 51-75%
