Description

Pflanzenschutzmittel Die Verwendung von fluorierten Fettsäuren, Fettalkoholen und Fettaminen mit jeweils mindestens q. Kohlenstoffatomen sowie von deren Derivaten als Pflanzenschutzmittel ist bereits vorgeschlagen worden.Plant protection products The use of fluorinated fatty acids, fatty alcohols and fatty amines each having at least q. Carbon atoms and their derivatives as a pesticide has already been proposed.

Es wurde nun. ,gefunden, daß ,außer derartigen Verbindungen auch die fluorierten Olefine -und :aliphatischen Verbindungen mit fluorhaltigen Olefinresten besonders brauchbare Pflanzenschutzmittel sind.It was now. , found that, in addition to such compounds, the fluorinated olefins and: aliphatic compounds with fluorine-containing olefin radicals are particularly useful pesticides.

Diese Verbindungen können beispielsweise erhalten werden durch Anlagerung von. Fluorwasserstoff an. Verbindungen mit zwei oder mehr D oppelbindun,g en in der Weise, daß im Reaktionsprodukt mindestens noch eine Doppelbindung enthalten ist. Man erhält z. B. Monofluorölsäure durch Anlagerung von i Mol Fluorwasserstoff an technische Leinölfettsäure. Zur Verwendung Aals Pflanzenschutzmittel eignen sich Monofluoräthylen, fluorölsiaures Natrium, Fluorölsäureinitril und ähnliche Körper. Brauchbar sind ferner beispielsweise Monofluorhexen, Monofluorbiuten, Mo:nofluorzimtsäure, fluorierte Tranfettsä%ure, fluorierte Sorbinsäure sowie die diesen Säuren entsprechenden Alkohole. Alle diese Verbindungen zeigen neben starker fungici:der Wirkung ;auch sehr ,gute insektenabtötende Eigenschaften. Zur Verbesserung der Netz-und Haftfähigkeit kann man den Mitteln besonders Haft-oder Netzmittel zusetzen; man kann ihnen .auch noch Wandere fun,gicide oder ins@ekticide Stoffe beimischen.These compounds can be obtained, for example, by attachment from. Hydrogen fluoride. Connections with two or more double bonds such that the reaction product still contains at least one double bond is. One obtains z. B. Monofluoroleic acid by the addition of 1 mole of hydrogen fluoride of technical linseed oil fatty acid. Eels are suitable for use as a plant protection product Monofluoroethylene, Sodium Fluoroleic Acid, Fluoroleic Acid Nitrile, and Similar Solids. Also usable are, for example, monofluorohexene, monofluorobutene, monofluorocinnamic acid, fluorinated fatty acid, fluorinated sorbic acid and the corresponding acids Alcohols. All these compounds show besides strong fungici: the effect; also very, good insecticidal properties. To improve the wetting and adhesive properties you can especially add adhesives or wetting agents to the agents; you can also still Wandere fun, gicide or ins @ ekticide add substances.

Die überlegene Wirkung ,einzelner Vertreter der genannten Verbindungen zeigen die nachstehenden Ergebnisse eines im Gewächshaus durchgeführten Versuches zur Bekämpfung der Peronospora: Konzen- tration Peronospora- Präparat der Spritz- befall brühe Unbehandelt ...... - starker Befall Kupferkalkbrühe . 0,5 kein Befall - 0,25 Befall - 0,125 Befall Fluorölsaures Natrium ....... o,oz kein Befall desgl.............. 0,005 kein Befall Fluoroleylamin..... 0,05 kein Befall - ..... 0,025 kein Befall Fluorhexylensaures Natrium ....... 0,025 kein Befall desgl.............. o,or25 kein Befall. Die Verwendung fluorhaltiger Vembindungen zu Mottenschutzzwecken ist bekannt; desgleichen die Verwendung von Acidatofluoroborsäuren und ihren Salzen sowie von Arylfluorsulfonaten und ihren Derivaten, zur Schädlingsbekämpfung. Indessen erreichtkeine, der bekannten Verbindungen eine so hohe Wirksamkeit auch bei Anwendung sehr kleiner Konzentrationen wie die hier beschriebenen Stoffe.The superior effect of individual representatives of the compounds mentioned is shown by the following results of an experiment carried out in a greenhouse to control downy mildew: Concentrate tration downy mildew Preparation of the spray infestation broth Untreated ...... - severe infestation Copper lime broth. 0.5 no infestation - 0.25 infestation - 0.125 infestation Fluorooleic acid Sodium ....... o, oz no infestation also .............. 0.005 no infestation Fluoroleylamine ..... 0.05 no infestation - ..... 0.025 no infestation Fluorohexylenic acid Sodium ....... 0.025 no infestation desgl .............. o, or25 no infestation. The use of fluorine-containing compounds for moth protection purposes is known; likewise the use of acidatofluoroboric acids and their salts and of aryl fluorosulfonates and their derivatives for pest control. However, none of the known compounds achieves such a high level of effectiveness even when using very low concentrations as the substances described here.
