Description
Verfahren zur Herstellung von Pflanzenschutzmitteln. Für die Bekämpfung der Pflanzenkrankheiten werden reine, zumeist auf chemischem Wege aus Naturprodukten hergestellte Stoffe verwendet. Die Erfindung beruht auf der Feststellung, daß eine Trennung der fungizid wirksamen Bestandteile von den unwirksamen Bestandteilen ohne Beeinträchtigung der Wirksamkeit durch Überführung des Gemenges in kolloidalen Zustand bzw. kolloidale Lösung vermied-en werden kann, und daß hierdurch fungizid wirkende Stoffe bzw. Verbindungen enthaltende wasserunlösliche Stoffe, welche an sich unwirksam sind, wie insbesondere die Naturprodukte des Mineralreiches und Abfallprodukte verschiedener Industrien, unmittelbar die Eignung als Pflanzenschutzmittel erhalten. Die Erfindung macht sich hierbei zunutze, daß durch Kolloidmühlen jeder Stoff, und zwar auch schwer lösliche Stoffe, unmittelbar in kolloidalen Zustand und in Lösung gebracht werden können.Process for the production of plant protection products. For the fight of the plant diseases are pure, mostly chemically from natural products manufactured substances are used. The invention is based on the finding that a Separation of the fungicidally active components from the inactive components without Impairment of the effectiveness by converting the mixture into a colloidal state or colloidal solution can be avoided, and that thereby fungicidal Substances or compounds containing water-insoluble substances, which in themselves are ineffective are, in particular, the natural products of the mineral kingdom and waste products different Industries, immediately obtain suitability as pesticides. The invention makes use of the fact that by means of colloid mills every substance, and indeed heavy soluble substances, immediately brought into a colloidal state and dissolved can.
Kolloidgemenge gemäß der Erfindung, in welchen auch das Verdünnungsmittel des Fungizids ein Kolloid ist, haben gegenüber Salzen, Salzlösungen u. dgl. nicht nur den Vorteil, daß sie indifferent sind und daher schädliche Nebenwirkungen auf der Pflanze nicht auftreten können, sondern auch den Vorteil, daß sie nicht auf der Reindarstellung des als fungizid -wirksamen Bestandteiles beruhen.Colloid mixture according to the invention, in which also the diluent of the fungicide is a colloid, have no effect on salts, salt solutions and the like only the advantage that they are indifferent and therefore have harmful side effects the plant can not occur, but also the advantage that it does not occur the pure representation of the fungicidally active ingredient.
Bei Ausführung des Verfahrens gemäß der Erfindung, welches im Wesen darin besteht, daß fungizid wirkende Verbindungen enthaltende unlösliche Gemenge durch Mahlung in Kolloidmühlen in kolloidalen Zustand übergeführt werden, kann eine Beschleunigung der Kolloidbildung durch Zusatz von Dispersionsbeschleunigern bzw. durch Anätzen erreicht werden, wobei durch entsprechenden Wasser- bzw. Flüssigkeitszusatz unmittelbar eine als Spritzmittel verwendbare Lösung erhalten werden kann.When carrying out the method according to the invention, which in essence consists in insoluble mixtures containing fungicidally active compounds be converted into a colloidal state by grinding in colloid mills, a Accelerated colloid formation by adding dispersion accelerators or can be achieved by etching, whereby by adding appropriate water or liquid a solution which can be used as a spray can be obtained directly.
Dem Verfahren gemäß der Erfindung können die in der Natur vorkommenden unlöslichen Mineralien, die Fungizide, wie Schwefelverbindungen, Arsenverbindungen, Kupferverbindungen usf., im Gemenge mit anderen Stoffen enthalten, wie z. B. Kupfererze, Arsenikkiese, Schwefelkiese u. dgl., unterworfen werden.The method according to the invention can be found in nature insoluble minerals that contain fungicides, such as sulfur compounds, arsenic compounds, Copper compounds, etc., contained in a mixture with other substances, such as B. copper ores, Arsenic pebbles, sulfur pebbles and the like., Are subjected.
Beispiel z.Example
Arsensulfid wird auf der Kolloidmühle mit Wasser vermahlen und eine kolloidale Lösung hergestellt, die ungefähr o,o8 bis o,2Prozent Arsen enthält. Diese Lösung wird in üblicher Weise verspritzt. Beispiel ?- Kupfersulfid wird auf der Kollo'idmühle mit Wasser vermahlen und eine kolloidale Lösung hergestellt, die ungefähr o,r bis 0,3 Prozent Kupfersulfid enthält. Diese Lösung wird verspritzt oder als Beizmittel benutzt.Arsenic sulfide is ground with water in a colloid mill and a colloidal solution is produced that contains approximately 0.08 to 0.2 percent arsenic. This solution is sprayed in the usual way. Example ? - Copper sulphide is ground with water on the colloid mill and a colloidal solution is made that contains approximately 0.4 to 0.3 percent copper sulphide. This solution is sprayed or used as a pickling agent.
Beispiel 3. Quecksilbersulfid wird auf der Kolloidmühle mit Wasser vermahlen und eine kolloidale Lösung hergestellt, die ungefähr o,o8 bis o,? Prozent' Quecksilbersulfid enthält. Diese Lösung wird verspritzt oder als Beizmittel benutzt.Example 3. Mercury sulphide is ground with water on the colloid mill and a colloidal solution is produced which is approximately 0.08 to 0.08. Percent 'contains mercury sulphide. This solution is sprayed or used as a pickling agent.
