Für die Bekämpfung von Insekten werden üblicherweise Insektizide in Form von Pulvern, Lösungen, die meist emulgierbar sind, oder Granulaten angewendet. Jede dieser Anwendungsarten weist jedoch Nachteile auf, wie die Verwehung von Pulver durch den Wind, die Schwierigkeit, die verstäubten oder versprühten Mittel in innige Berührung mit den betreffenden Pflanzenteilen zu bringen, und schließlich und nicht zum wenigsten die Gefahr einer Vergiftung des die Insektizide handhabenden Personals.For the control of insects, insecticides are usually in the form of powders, Solutions, which are usually emulsifiable, or granules are used. Any of these types of applications however, it has drawbacks such as the wind blowing of powder, the difficulty of dusting or to bring the sprayed agent into intimate contact with the relevant parts of the plant, and finally, and not least, the danger of poisoning those handling the insecticides Staff.
Bei Granulaten zeigen sich zwar auch manche, Nachteile, die den Pulvern und Lösungen anhaften, doch zeigen landwirtschaftliche und staatliche Stellen großes Interesse an Granulaten, weil sie m toxikologischer Hinsicht noch die sicherste Anwendungsform für das damit arbeitende Personal darstellen.In the case of granules, there are also some disadvantages that stick to the powders and solutions, however, agricultural and government agencies show great interest in granules because they are more toxic Still represent the safest form of application for the personnel working with it.
Diese Sicherheit wird aber noch durch folgende Faktoren beeinträchtigt:However, this security is also impaired by the following factors:
Der Staubanteil ist sehr hoch und wird oft noch durch Abrieb beim Transport vermehrt. Staub wird durch den Wind leicht fortgetrieben und richtet dann auf angrenzenden Gebieten oft großen Schaden an, besonders wenn dort keine Vorsichtsmaßnahmen getroffen sind, wie z. B. der Abtrieb von Vieh.The dust content is very high and is often increased by abrasion during transport. Dust becomes easily carried away by the wind and then often causes great damage in adjacent areas, especially if no precautionary measures have been taken there, such as B. the drive of cattle.
Das spezifische Gewicht der Granulate ist häufig sehr gering und leistet dann ebenfalls einer Verwehung Vorschub, erschwert aber besonders das gleichmäßige Bedecken der zu behandelnden Flächen mit Flächen von Maschinen oder Handapplikatoren, wie beispielsweise bei Vermiculit-Granulat.The specific weight of the granules is often very low and then also drifts away Feed, but makes it particularly difficult to cover the surfaces to be treated evenly with surfaces of machines or hand applicators, such as vermiculite granules.
Die Absorbier- und Absorbiereigenschaften der bisher verwendeten Trägermaterialien machten eine etwa doppelt so große Menge an Insektizid je behandelter Fläche erforderlich, wie der Toxicität des Insektizids entsprach.The absorption and absorption properties of the carrier materials used up to now made one about twice the amount of insecticide required per treated area as the toxicity of the Insecticide.
Handelsgranulate mit Insektiziden, die meist schwerer als Wasser sind, haben den Nachteil, am Boden von Gewässern das Insektizid nur sehr langsam freizugeben. Das ist eine Folge der Anreicherung des Insektizids am Granulat und des größeren spezifischen Gewichts des das Insektizids enthaltenden, das Granulat umgebenden Wassers.Commercial granules with insecticides, which are usually heavier than water, have the disadvantage of am Bottom of water releases the insecticide very slowly. That is a consequence of the enrichment the insecticide on the granules and the greater specific gravity of the insecticide containing, the granulate surrounding water.
Es wurde nun überraschenderweise gefunden, daß ein Granulat, hergestellt aus einem Gemenge aus
90 bis 91% Zement, Gips oder Sandkörner, 6% Korkpulver von weniger als 0,25 mm Teilchendurchmesser,
2% Klebstoff und 1 bis 2% Insektizid keinen der erwähnten Mängel mehr besitzt, sondern erhebliche
Vorteile bei der Anwendung bietet, weil die Heraufsetzung der Härte des Granulats den Staubanteil
verringert, eine Erhöhung des spezifischen Gewichts Verfahren zum Herstellen eines Insektizids
in GranulatformIt has now surprisingly been found that a granulate made from a mixture of 90 to 91% cement, plaster of paris or grains of sand, 6% cork powder with a particle diameter of less than 0.25 mm, 2% adhesive and 1 to 2% insecticide does not have any of the defects mentioned has more, but offers considerable advantages in application, because increasing the hardness of the granulate reduces the dust content, an increase in the specific gravity Process for the production of an insecticide

1S luste verringert oder sogar vermeidet und eine Ersparnis an Zeit und Geld bringt, weil es möglich wird, größere Gebiete in kürzerer Zeit zu behandeln, eine Verringerung des ad- und absorbierbaren Anteils die Abgabe von Insektizid an die Umgebung beschleunigt und dadurch einer Hydrolyse vorbeugt, die eine Verschwendung des Insektizids bedeutet und ein Nutzbarmachen physikalischer Verteilungsmethoden im Wasser die Abgabe von Insektizid an die Umgebung beschleunigt. Bei einer Mückenbekämpfung wird außerdem das Insektizid an die an der Wasseroberfläche atmenden Mückenlarven herangebracht und die Einwirkung verstärkt. 1 Loss is reduced or even avoided and results in a saving of time and money, because it becomes possible to treat larger areas in a shorter time, a reduction in the absorbable and absorbable portion accelerates the release of insecticide to the environment and thus prevents hydrolysis which means wasting the insecticide and harnessing physical methods of dispersion in the water accelerates the release of insecticide to the environment. When combating mosquitoes, the insecticide is also brought to the mosquito larvae breathing on the surface of the water and the effect is intensified.
Das nach obigen Angaben hergestellte Granulat ermöglicht eine Verringerung der anzuwendenden Menge an Granulat um 40 bis 50%. Damit ist eine ebenso gute Insektenbekämpfung wie mit etwa der doppelten Menge bekannter Präparate möglich.The granules produced according to the above information allow a reduction in the amount to be used Amount of granules around 40 to 50%. This is just as good an insect control as with the double the amount of known preparations possible.
Bewährt hat sich das Korkgranulat gemäß der Erfindung besonders in Verbindung mit folgenden Insektiziden: The granulated cork according to the invention has proven itself particularly in connection with the following insecticides:

MalathionMalathion
O,O-Dimethyl-S-1,2 dicarbäthoxyäthyl-dithiophosphat. O, O-dimethyl-S-1,2-dicarbethoxyethyl-dithiophosphate.
Die gesteigerte Wirksamkeit ist in erster Linie dem Kork zuzuschreiben, der eine schnelle, gründliche und äußerst feine Verteilung des Insektizids in dem zu behandelnden Wasser gewährleistet. Außerdem ist die Bildung eines Konzentrationsgefälles um jedes kleine Korkteilchen besonders stark ausgebildet undThe increased effectiveness is primarily due to the cork, which is fast, thorough and ensures extremely fine distribution of the insecticide in the water to be treated. Also is the formation of a concentration gradient around each small cork particle is particularly strong and

von entscheidender Bedeutung, so daß eine fast vollständige Abgabe des Insektizids an das Wasser in kürzester Zeit erfolgt. Bei dem handelsüblichen E-605-Granulat ist die Abgabe unvollständig, weil das genannte Insektizid nur eine geringe Löslichkeit, etwa 24 mg je Liter Wasser bei 25° C, hat.of vital importance so that an almost complete release of the insecticide to the water in takes place in the shortest possible time. In the case of the commercially available E-605 granules, the delivery is incomplete because said insecticide has only a low solubility, about 24 mg per liter of water at 25 ° C.
Durch Eintropfen von Wasser in Gips (Calciumsulfat) oder Zement stellt man kleine Kügelchen her oder geht von Sand gewünschter Körnung aus, die 90 Gewichtsprozent des herzustellenden Mittels bilden. Die Teilchen werden mit 6 Gewichtsprozent einer dünnen Schicht eines flüssigen Klebemittels, der Billigkeit halber vorteilhaft einer 60%igen Sulfitablauge (Ligninsulfonate überzogen und dann die erforderliche Menge Korkpulver — 6 Gewichtsprozent —, das durch ein Sieb mit einer Maschenweite von 0,25 mm gegangen ist, hinzugegeben. Nach kurzer Mischung, Trocknung und Siebung, um die gewünschte Korngröße abzuscheiden, sprüht man 1 bisBy dripping water into plaster of paris (calcium sulphate) or cement, small spheres are produced or is based on sand of the desired grain size, which makes up 90 percent by weight of the agent to be produced. The particles are made with 6 percent by weight of a thin layer of a liquid adhesive that is cheap For the sake of advantage, a 60% sulphite waste liquor (coated with lignosulphonates and then the required Amount of cork powder - 6 percent by weight - passed through a sieve with a mesh size of 0.25 mm is added. After brief mixing, drying and sieving to the desired Separate grain size, you spray 1 to
2 Gewichtsprozent des Insektizids auf das Granulat. Das Insektizid in Form von E 605 ergibt ein für die Mückenbekämpfung äußerst wirkungsvolles Granulat, das sich bei seiner Untersuchung als weitgehend as staubfrei und wegen seines schweren Kerns aus Gips, Zement oder Sand als besonders geeignet erwies.2 percent by weight of the insecticide on the granules. The insecticide in the form of E 605 gives a for that Mosquito control extremely effective granules, which in its investigation turned out to be largely as dust-free and proved to be particularly suitable because of its heavy core made of plaster of paris, cement or sand.
Die chemische Untersuchung eines Wassers, zu dem Korkparathiongranulat, hergestellt gemäß dem vorstehenden Beispiel gegeben war, ergab, daß nachThe chemical analysis of a water to which cork parathion granules, produced according to the given above, showed that after
3 Stunden 70%> des Parathions in Lösung gegangen waren, während bei handelsüblichen Parathiongranulaten nach 3 Stunden lediglich 20 bis 35% gelöst waren. Nach 24 Stunden waren von dem Korkparathiongranulat gemäß der Erfindung 90%, von dem handelsüblichen Parathiongranulat nur 40 bis 45°/o in Lösung gegangen.3 hours 70%> of the parathion has gone into solution were, while with commercial parathion granules after 3 hours only 20 to 35% dissolved was. After 24 hours, 90% of the cork parathion granules according to the invention were of that commercial parathion granulate only 40 to 45% went into solution.
90 Gewichtsprozent Gips, Zement oder Sand werden in einem Mischer abwechselnd mit Wasser und einer Mischung aus 6 Gewichtsprozent Korkpulver, an das vorher ein Insektizid in einer Menge von 2 Gewichtsprozent gesprüht war, und einem Klebstoff in Pulverform in einer Menge von 2 Gewichtsprozent behandelt und anschließend getrocknet. Die benötigten Trocknungszeiten sind etwas länger als bei dem Verfahren nach Beispiel 1, auch war ein gewisser Insektizidverlust zu beobachten.90 percent by weight of gypsum, cement or sand are mixed with water and alternately in a mixer a mixture of 6 percent by weight cork powder, previously an insecticide in an amount of 2 percent by weight was sprayed, and an adhesive in powder form in an amount of 2 percent by weight treated and then dried. The drying times required are a little longer than that Procedure according to Example 1, a certain loss of insecticide was also observed.
Es wird nach Beispiel 1 verfahren, jedoch der Anteil an Korkpulver zu etwa 40% durch Microballone ersetzt. Microballone ist ein in den Vereinigten Staaten von Amerika erhältliches Handelsprodukt aus Phenolharzkügelchen, die mit Stickstoff gefüllt sind. Die Korngröße ist wieder kleiner als 0,25 mm.The procedure is as in Example 1, but the proportion of cork powder is about 40% using microballoons replaced. Microballoons is a commercial product available in the United States of America Phenolic resin beads filled with nitrogen. The grain size is again less than 0.25 mm.
