Description

Schädlingsbekämpfungsmittel Im Patent 674 488 sind Schädlingsbekämpfungsmittel beschrieben, die eine Lösung der gegen tierische und pflanzliche Schädlinge wirksamen Stoffe aus Deriis, Pyrethrum oder ähnlich wirkenden Drogen in einem organischen. Lösungsmittel ientalten und die dadurch gekennzeichnet sind, daß sie eine der nach dem Patent 6o5 973 erhältlichen Verbindungen als Emulgator enthalten. Es wurde ausgeführt, daß diese Schädlingsbekämpfungsmittel sich einerseits durch große Haltbarkeit der empfindlichen Wirkstoffe und anderseits dadurch auszeichnen, daß sie sich beim Einrühren in Wasser zu Emulsionen hoher Dispersität und daher großer Wirksamkeit verteilen lassen.Pesticides The patent 674 488 describes pesticides which are a solution of substances effective against animal and plant pests from Deriis, Pyrethrum or similar drugs in an organic drug. Ientalten solvent and which are characterized in that they contain one of the compounds obtainable by the Patent 6o5 973 as an emulsifier. It has been stated that these pesticides are distinguished on the one hand by the long shelf life of the sensitive active ingredients and on the other hand by the fact that they can be distributed to emulsions of high dispersity and therefore great effectiveness when stirred into water.

Bei weiterer Bearbeitung dieses Gebietes wurde nun gefunden, daß zur Erzielung solcher Emulsionen die Gegenwart eines organischen Lösungsmittels in den Mitteln gemäß Hauptpatent nicht unbedingt erforderlich ist, daß vielmehr durch Behandlung der Wirkstoffe mit den erwähnten Emulgiermitteln Präparate erhalten werden können, die nach dem Einrühren in Wasser eine feine Verteilung der Wirkstoffe gewährleisten: Man kann die Schädlingsbekämpfungsmittel beispielsweise so herstellen, daß man die betreffenden Drogen oder ihre Wirkstoffe mit diesen Emulgiermitteln innig vermischt. Je nach den Eigenschaften der verwendeten Emulgiermittel können die erhaltenen Produkte verschiedene Konsistenz aufweisen. Kommen z. B. flüssige Emulgiermittel zur Anwendung, so können die Wirkstoffe in vielen Fällen unmittelbar in ihnen gelöst werden. Bei Verwendung von anderen Emulgiermitteln können feste oder salbenartige Präparate erhalten werden. Zur Erzielung von völlig homogenen Produkten kann es vorteilhaft sein, aus mit Lösungsmitteln angesetzten Gemischen, wie sie z. B. im Patent 674 488 angegeben sind, diese Lösungsmittel wieder zu verjagen. In allen Fällen erhält man Präparate, die beim Eintragen in Wasser genügend lange Zeit haltbare Emulsionen geben. Die Schädlingsbekämpfungsmittel können außerdem noch beliebige Zusätze enthalten. Auch können Gemische verschiedener Drogen oder Drogenbestandteile angewendet werden. Beispiele i. ioTeile Rotenon werden unter gelinde Envärmen in iooTeilen oxäthylierteni': nusöl gelöst. Das erhaltene Produkt' beim Einrühren in Wasser, dem Natri= :l carbonat oder andere Alkalien zugesetzt sein; können. eine fast klare Lösung. 2. iooTeile feine gemahlene Derriswurzel und 5o Teile oxäthyliertes Rizinusöl werden kurze Zeit mit 5oo Teilen Äther erhitzt. Das nach Abdampfen des Äthers hinterbleibende Produkt gibt beim Einrühren in Wasser eine Emulsion, die von dem sich absetzenden Derrisschrot abgehoben werden kann. . , 3. i o Teile Rotenon werden unter gelindem Erwärmen in ioo Teilen oxäthyliertem Oleylalkohol gelöst. Das erhaltene Produkt gibt beim Einrühren in Wasser eine homogene Emulsion.In further processing of this area it has now been found that the presence of an organic solvent in the agents according to the main patent is not absolutely necessary in order to achieve such emulsions; ensure a fine distribution of the active ingredients: the pesticides can be prepared, for example, by intimately mixing the drugs in question or their active ingredients with these emulsifiers. Depending on the properties of the emulsifying agents used, the products obtained can have different consistencies. Come z. If, for example, liquid emulsifiers are used, the active ingredients can in many cases be dissolved directly in them. If other emulsifying agents are used, solid or ointment-like preparations can be obtained. In order to achieve completely homogeneous products, it can be advantageous to use mixtures prepared with solvents, as they are, for. B. in patent 674 488 are given to drive off these solvents again. In all cases, preparations are obtained which, when immersed in water, give emulsions that can be kept for a long enough time. The pesticides can also contain any additives. Mixtures of different drugs or drug components can also be used. Examples i. io parts of Rotenone are taken to be the least Heating in 100 parts oxethylated: nut oil dissolved. The product received ' when stirring into water, the sodium =: l carbonate or other alkalis may be added; can. an almost clear solution. 2. 100 parts of finely ground derris root and 50 parts of oxethylated castor oil are briefly heated with 500 parts of ether. The product remaining after evaporation of the ether gives an emulsion when stirred into water, which can be lifted from the derris meal which is deposited. . 3. 10 parts of Rotenone are dissolved in 100 parts of oxethylated oleyl alcohol with gentle heating. The product obtained gives a homogeneous emulsion when stirred into water.

q.. 1o Teile Rotenon werden unter gelindem Erwärmen in ioo Teilen oxäthyliertem Dodecylphenol gelöst. Das erhaltene Produkt gibt beim Einrühren in Wasser eine homogene Emulsion.q .. 10 parts of Rotenone are converted into 100 parts with gentle warming Dissolved oxethylated dodecylphenol. The product obtained is when stirred into Water a homogeneous emulsion.

5. i o Teile Rotenon werden unter gelindem Ji#nvärmen in ioo Teilers oxäthyliertem Iso-O#@tylphenol gelöst. Das erhaltene Produkt gibt beim Einrühren in Wasser eine schwach trübe Lösung.5. 100 parts of Rotenone are converted into 100 parts with gentle warming oxethylated iso-O # @ tylphenol dissolved. The product obtained gives on stirring a slightly cloudy solution in water.

6. i o Teile Rotenon werden unter gelindem Erwärmen in i oo Teilen oxäthyliertem Oxyphenolcamphan gelöst. Das erhaltene Produkt gillt beim Einrühren in Wasser eine schwach trübe Lösung.6. i o parts of Rotenone are converted into i oo parts with gentle heating dissolved oxyethylated oxyphenol camphane. The product obtained glows when stirred in a slightly cloudy solution in water.
