In vorgenannter Formel stehen Ri und Ro für gleiche oder verschiedene Alkylreste mit 1 bis 4 Kohlenstoffatomen, Rz stellt darüber hinaus auch einen niederen Alkoxyrest dar.In the above formula, Ri and Ro stand for identical or different alkyl radicals with 1 to 4 carbon atoms, Rz also represents a lower alkoxy radical.
In der USA.-Patentschrift 2 690 450 werden bereits Thiolphosphorsäurearylester beschrieben, die parasitizide, insbesondere insektizide, aber auch fungizide Eigenschaften besitzen. Aus dieser Veröffentlichung geht jedoch nur hervor, daß sich die obengenannten Verbindungen als Fungizide zur Bekämpfung von Braunfaule (Sclerotinia fructicola) und der Dörrfleckenkrankheit (Alternaria solani) eignen. Dagegen ist der USA.-Patentschrift 2 690 450 nicht zu entnehmen, ob die dort offenbarten Verbindungen auch eine für die Praxis ausreichende Wirksamkeit gegen pilzliche Krankheitserreger an Reispflanzen, besonders der durch den Pilz Piricularia oryzae verursachten, besitzen.US Pat. No. 2,690,450 already describes aryl thiolphosphorate, which is parasiticidal, in particular have insecticidal, but also fungicidal properties. From this publication However, it only emerges that the above compounds can be used as fungicides for combating Brown rot (Sclerotinia fructicola) and dry spot disease (Alternaria solani) are suitable. On the other hand, the US Pat. No. 2,690,450 does not reveal that whether the compounds disclosed there also have an effectiveness against which is sufficient in practice fungal pathogens on rice plants, especially those caused by the fungus Piricularia oryzae, own.

Wie weiterhin gefunden wurde, zeichnen sich die neuen Thiolphosphor- (-phosphon-)säureester durch hervorragende fungitoxische Eigenschaften, insbesondere gegenüber pilzlichen Krankheitserregern an Reispflanzen, aus. überraschenderweise sind sie in dieser Hinsicht den bekannten und für den gleichen Zweck bereits vorgeschlagenen Wirkstoffen analoger Konstitution eindeutig überlegen. Die Verfahrensprodukte stellen somit eine echte Bereicherung der Technik dar.As was also found, the new thiolphosphorus (-phosphonic) acid esters are characterized by excellent fungitoxic properties, especially against fungal pathogens Rice plants, from. Surprisingly, in this regard, they are the most well-known and for the same Purpose of already proposed active ingredients of analogous constitution clearly superior. The process products are a real asset to the Technology.
Die verfahrensgemäß zu verwendenden Halogenmethylnaphthaline sind aus der Literatur bekannt und können auch in technischem Maßstab leicht hergestellt werden.The halomethylnaphthalenes to be used according to the process are known from the literature and can also be easily produced on an industrial scale.
