Description
Fungizid für den Pflanzenschutz Es ist bekannt, substituierte Cyclohexylmorpholine als fungizide Wirkstoffe zu verwendet. Ihre Wirkung befriedigt jedoch nicht.Fungicide for crop protection It is known substituted cyclohexylmorpholine to be used as fungicidal agents. However, their effect is not satisfactory.
Es wurde gefunden, daß Verbindungen der Formel in der R einen Alkyl- oder alkylsubstituierten Cyclohexylrest mit 1 bis 9 Kohlenstoffatomen bedeutet und n die Bedeutung 1 oder 2 hat, wobei R1 und R2 gleich oder verschieden sind, und ihre Salze eine gute fungizide Wirkung haben.It has been found that compounds of the formula in which R denotes an alkyl or alkyl-substituted cyclohexyl radical having 1 to 9 carbon atoms and n denotes 1 or 2, where R1 and R2 are identical or different, and their salts have a good fungicidal effect.
Als Anion der Salze kommen insbesondere die Anionen anorganischer Säuren, z. B. Salzsäure, Schwefelsäure, Salpetersäure, Bromwasserstoffsäure und Phosphorsäure, in Betracht. Auch die Salze organischer Säuren sind als Wirkstoffe geeignet. The more inorganic anions, in particular, are used as the anions of the salts Acids, e.g. B. hydrochloric acid, sulfuric acid, nitric acid, hydrobromic acid and Phosphoric acid. The salts of organic acids are also used as active ingredients suitable.
Die erfindungsgemäßen Wirkstoffe können analog bekannten Methoden hergestellt werden. Bei spiel sweise können sie durch Umsetzung von primären oder sekundären Aminen oder Alkanolaminen mit Alkylenoxyden zu Dialkanolaminen und Ringschluß dieser Verbindungen mit dehydratisierenden Mitteln erhalten werden. Die Dehydratisierung kann beispielsweise mit konzentrierter Schwefelsäure, Salzsäure oder Bromwasserstoffsäure oder dehydrati sierenden Katalysatoren, z. B. Aluminiumoxyd, Aluminiumphosphat, Borphosphat, in flüssiger Phase oder in der Gasphase vorgenommen werden. The active compounds according to the invention can analogously to known methods getting produced. For example, you can implement primary or secondary amines or alkanolamines with alkylene oxides to give dialkanolamines and ring closure of these compounds can be obtained with dehydrating agents. The dehydration can for example with concentrated sulfuric acid, hydrochloric acid or hydrobromic acid or dehydrati-generating catalysts, e.g. B. aluminum oxide, aluminum phosphate, Boron phosphate, in the liquid phase or in the gas phase.
Eine weitere Herstellungsmöglichkeit ist die hydrierende Aminierung von Ketonen mit primären Aminoalkoholen zu N-substituierten sekundären Alkanolaminen, die, wie oben bereits beschrieben, mit Alkylenoxyden umgesetzt werden. Die so erhaltenen Dialkanolamine werden in der bereits beschriebenen Weise mit dehydratisierenden Mitteln zu einem heterocyclischen Ring geschlossen. Another production possibility is hydrogenative amination from ketones with primary amino alcohols to N-substituted secondary alkanolamines, which, as already described above, are reacted with alkylene oxides. The so obtained Dialkanolamines are dehydrated in the manner already described Means closed to a heterocyclic ring.
Ferner kann man gegebenenfalls substituierte 2,2'-Dichloralkyläther mit primären Aminen in Gegenwart von säurebindenden Mitteln zu Verbindungen mit einem heterocyclischen Ring umsetzen. Optionally substituted 2,2'-dichloroalkyl ethers can also be used with primary amines in the presence of acid-binding agents to form compounds with implement a heterocyclic ring.
Beispielsweise erhält man aus N-substituiçrten Dialkanolaminen mit Thionylhalogeniden Morpholinsalze. For example, from N-substituted dialkanolamines one obtains with Thionyl halides morpholine salts.
In der folgenden Tabelle sind einige der.erfindungsgemäß zu verwendenden
Wirkstoffe aufgeführt.
Die Wirkung der erfindungsgemäß zu verwendenden Verbindungen erstreckt sich besonders auf echte Mehltaupilze, aber auch auf andere Schadpilze, z. B. Botrytis cinerea.The effect of the compounds to be used according to the invention extends particularly on powdery mildew, but also on other harmful fungi, e.g. B. Botrytis cinerea.
Beispiel 1 Blätter von in Töpfen gewachsenen Gerstenkeimlingen werden mit wässerigen Emulsionen aus 80% Wirkstoff und 20% Emulgiermittel besprüht und nach dem Antrocknen des Spritzbelages mit Oidien (Sporen) des Gerstenmehltaus (Erysiphe graminis var. hordei) bestäubt, Die Versuchspflanzen werden anschließend im Gewächshaus bei Temperaturen zwischen 20 und 22°C und 75 bis 800/0 relativer Luftfeuchtigkeit aufgestellt. Nach 10 Tagen wird das Ausmaß der Mehltaupilz-Entwicklung ermittelt. Example 1 Leaves of potted barley seedlings are obtained sprayed with aqueous emulsions of 80% active ingredient and 20% emulsifier and after the spray coating with oidia (spores) of barley powdery mildew (Erysiphe graminis var. hordei), the test plants are then in the greenhouse at temperatures between 20 and 22 ° C and 75 to 800/0 relative humidity set up. The extent of powdery mildew development is determined after 10 days.
Die Zahlen in der Tabelle haben folgende Bedeutung: 0 = kein Befall,
abgestuft bis 5 = Totalbefall.
B e i s p i e l 2 Blätter von in Töpfen gewachsenen Gurkenkeimlingen
werden mit wässerigen Emulsionen aus 80°/o Wirkstoff und 20% Emulgiermittel besprüht
und nach dem Antrocknen des Spritzbelages mit
Oidien (Sporen) des Gurkenmehltaus
(Erysiphe cichoriacearum) bestäubt. Die Versuchspflanzen werden anschließend - im
Gewächshaus bei Temperaturen zwischen 20 und 22°C und 75 bis 800/0 relativer Luftfeuchtigkeit
aufgestellt. Nach 10 Tagen wird das Ausmaß der Mehltaupilz-Entwicklung ermittelt.
