Abstract

The invention relates to novel insecticidal gassing agents, produced using active ingredient granulate, the method for production of such gassing agents and use thereof for preventing harmful and/or troublesome insects.

Description

Insektizide Begasungsmittel enthaltend Wirkstoff in Form eines Granulats Insecticidal fumigant containing active ingredient in the form of granules
Die vorliegende Erfindung betrifft neuartige insektizide Begasungsmittel, die unter Benutzung von Wirkstoffgranulaten hergestellt werden, die Verfahren zur Herstellung solcher Begasungsmittel sowie deren Verwendung zur Bekämpfung schädlicher und/oder lästiger Insekten.The present invention relates to novel insecticidal fumigants prepared using active ingredient granules, to the methods of making such fumigants, and to their use for controlling harmful and / or troublesome insects.
Brennbare insektizide Begasungsmittel sind seit langem bekannt und kommerziell erhältlich. Sie werden z.B. als „Mosquito Coil" (oder einfach „Coils") hergestellt und vertrieben. In diesen Coils können verschiedene Insektizide eingesetzt werden, z.B. aus der Klasse der Pyrethroide. Manche eingesetzte Wirkstoffe weisen bei üblichen Coils allerdings den Nachteil auf, dass sie aufgrund chem.-physik. Parameter die Tendenz haben, relativ schnell entweichen, so dass ihre Haltbarkeit begrenzt ist. Der Flüchtigkeit mancher Pyrethroid versucht man durch die Zugabe von Verdampfungshemmern, z.B. Adipaten oder Sebazaten, entgegenzuwirken (z.B. EP 0 693 254), allerdings nur mit begrenztem Erfolg. Des Weiteren trocknet man diese Coils bei niedrigeren Temperaturen, um solche Wirkstoffverluste bei der Herstellung zu minimierenFlammable insecticidal fumigants have long been known and commercially available. They are e.g. manufactured and distributed as "Mosquito Coil" (or simply "coils"). In these coils, various insecticides can be used, e.g. from the class of pyrethroids. However, some active ingredients used in conventional coils, however, have the disadvantage that they due Chem.-physic. Parameters tend to escape relatively quickly, so their durability is limited. The volatility of some pyrethroid is attempted by the addition of evaporation inhibitors, e.g. Adipates or sebacates (e.g., EP 0 693 254), but with limited success. Furthermore, these coils are dried at lower temperatures to minimize such losses of active ingredient in the preparation
Es besteht demnach Bedarf für verbesserte brennbare insektizide Begasungsmittel, die eine längere Lagerstabilität aufweisen. Dementsprechend ist die der vorliegenden Erfindung zugrunde liegende technische Aufgabe die Bereitstellung lang haltbarer brennbarer insektizider Begasungsmittel sowie die Bereitstellung von Verfahren zu ihrer Herstellung. Diese Aufgabe wird durch die erfindungsgemäßen Begasungsmittel gelöst, die sich dadurch auszeichnen, dass der insektizide Wirkstoff in die Mittel in Form eines Granulats eingearbeitet wird.There is therefore a need for improved combustible insecticidal fumigants which have a longer shelf life. Accordingly, the technical problem underlying the present invention is to provide long-lasting combustible insecticidal fumigants and to provide processes for their preparation. This object is achieved by the inventive fumigants, which are characterized in that the insecticidal active ingredient is incorporated into the compositions in the form of granules.
Die vorliegende Erfindung betrifft daher neuartige brennbare insektizide Begasungsmittel, die unter Benutzung eines wirkstoffhaltigen Granulats hergestellt werden, die Verfahren zur Herstellung solcher Begasungsmittel sowie deren Verwendung zur Bekämpfung schädlicher und/oder lästiger Insekten. Außerdem betrifft die Erfindung die Verwendung von Granulaten zur Herstellung von brennbaren insektiziden Begasungsmitteln.The present invention therefore relates to novel combustible insecticidal fumigants prepared using active ingredient-containing granules, the processes for producing such fumigants and their use for controlling harmful and / or troublesome insects. Moreover, the invention relates to the use of granules for the production of combustible insecticidal fumigants.
Überraschenderweise wurde gefunden, dass die erfindungsgemäßen brennbaren insektiziden Begasungsmittel deutlich weniger zum Verlust von Wirkstoff durch Ausgasung neigen als die im Stand der Technik beschriebenen Vorgänger. Dadurch lässt sich eine längere Haltbarkeit oder ein reduzierter Wirkstoffeinsatz verwirklichen.Surprisingly, it has been found that the combustible insecticidal fumigants according to the invention are significantly less prone to loss of active ingredient through outgassing than the predecessors described in the prior art. As a result, a longer shelf life or a reduced use of active ingredient can be realized.
Gegenstand der vorliegenden Erfindung ist daher ein brennbares insektizides Begasungsmittel, dadurch gekennzeichnet, dass dieses ein Insektizid, ein Granulat als Trägermaterial sowie einen Verdampfungshemmer umfasst. Dabei sind das Insektizid und der Verdampfungshemmer im Granulat enthalten. Für die Herstellung der erfindungsgemäßen Mittel ist kein besonderer technischer Aufwand zu treiben. Vielmehr können vorhandene Apparaturen weiterhin benutzt werden. So ist auch der eigentlich Herstellungsprozess der brennbaren insektiziden Begasungsmittel in keiner Weise verschieden von dem bisher verwendeten und dem Fachmann bekannten Verfahren. Es unterscheidet sich lediglich in der Art eingesetzten Formulierung vom Stand der Technik.The subject of the present invention is therefore a combustible insecticidal fumigant, characterized in that it comprises an insecticide, a granulate as carrier material and an evaporation inhibitor. The insecticide and the evaporation inhibitor are contained in the granules. For the preparation of the compositions according to the invention no special technical effort is required. Rather, existing equipment can continue to be used. Thus, the actual production process of the combustible insecticidal fumigant is in no way different from the previously used and known in the art methods. It differs only in the type used formulation of the prior art.
Obwohl die erfindungsgemäßen Mittel nachfolgend teils als „Coil" bezeichnet werden, ist es selbstverständlich, dass die Mittel keineswegs sipralförmig sein müssen, sondern in beliebigen Ausprägungen hergestellt und die erfϊndungswesentlichen Eigenschaften haben können.Although the agents according to the invention are sometimes referred to below as "coils", it goes without saying that the agents in no way have to be sipral-shaped, but can be produced in any desired forms and have the properties essential to the invention.

Im Fall eines flüssigen Verdampfungshemmers kann dieser zum Lösen bzw. zum -Suspendieren des Insektizids benutzt werden und dann auf den Träger gesprüht werden.In the case of a liquid evaporation inhibitor, it can be used for dissolving or suspending the insecticide and then sprayed on the carrier.
Bevorzugt werden die insektizidhaltigen Granulate hergestellt, indem das Insektizid in dem entsprechenden, bevorzugt flüssigen, Verdampfungshemmer gelöst und anschließend auf das Trägermaterial appliziert wird. Die Applikation erfolgt bevorzugt durch Sprühapplikation.The insecticide-containing granules are preferably prepared by dissolving the insecticide in the corresponding, preferably liquid, evaporation inhibitor and then applying it to the carrier material. The application is preferably carried out by spray application.
Der Gehalt an Verdampfungshemmer, bezogen auf die in den erfindungsgemäßen Mitteln enthaltenen Granulate, kann in einem weiten Bereich variiert werden. Nach oben begrenzt wird der Gehalt dadurch, dass die Fließfähigkeit des Granulats erhalten bleiben sollte. Typischerweise liegt er bei 0,5 bis 50 Gew.-%, bevorzugt bei 1 bis 30 Gew.-%, besonders bevorzugt bei 2 bis 25 Gew.- % und ganz besonders bevorzugt bei 5 bis 20 Gew.-%.The content of evaporation inhibitor, based on the granules contained in the agents according to the invention, can be varied within a wide range. The upper limit is the content in that the flowability of the granules should be maintained. Typically lies it is from 0.5 to 50% by weight, preferably from 1 to 30% by weight, more preferably from 2 to 25% by weight and most preferably from 5 to 20% by weight.
Ebenfalls Gegenstand der vorliegenden Erfindung sind Granulate, enthaltend Trägermaterial, Insektizid und Verdampfungshemmer, wobei die Granulate Teilchengrößen von 50 μm bis 800 μm aufweisen.Likewise provided by the present invention are granules containing carrier material, insecticide and evaporation inhibitor, the granules having particle sizes of 50 μm to 800 μm.
Die Herstellung der erfindungsgemäßen Begasungsmittel erfolgt nach bekannten Methoden, die im Folgenden beispielhaft erläutert werden. Prinzipiell ist jedes bekannte Herstellungsverfahren leicht so veränderbar, dass damit erfindungsgemäße Mittel hergestellt werden können.The preparation of the fumigant according to the invention is carried out by known methods, which are exemplified below. In principle, any known production method is easily changeable so that means according to the invention can be produced.
Zur Erzeugung einer Klebewirkung werden Stärke oder stärkeähnliche Produkte unterschiedlicher Herkunft eingesetzt und in heißem Wasser oder durch Wasserdampf gekocht. Dabei entsteht ein klebriger und gerade noch fließfähiger Teig. Auch der Einsatz von industriell erzeugter, vorgequollener Stärke in pulverisierter Form ist zur Vereinfachung des Prozesses möglich. Wegen der höheren Kosten werden solche Produkte jedoch selten eingesetzt. In höher mechanisiertenTo produce an adhesive effect starch or starch-like products of different origin are used and cooked in hot water or steam. This creates a sticky and just still flowable dough. Also, the use of industrially produced, pre-swollen starch in powdered form is possible to simplify the process. However, because of the higher cost, such products are rarely used. In higher mechanized
Betrieben und größeren Produktionschargen wird dieser Prozessschritt in speziellen Knetern durchgeführt.On farms and larger production batches, this process step is carried out in special kneaders.
Der Basisrohstoff der Begasungsmittel sind Holzmehle unterschiedlicher Provenienz entsprechend der lokalen Verfügbarkeit. Mehle von tropischen Harthölzern und Kokosschalen in verschiedenen Mischungsverhältnissen ergeben Vorteile sowohl in der Herstellung als auch in der Produktqualität. Das Holzmehl kann auch durch gemahlene Holzkohle ersetzt werden. Dies ergibt schwarze Produkte, die keinen weiteren Farbstoff benötigen. Für die Herstellung der Mischung kommen große Band- oder Schaufelmischer zum Einsatz. Zu den Holzmehlen werden auch die wirkstoffhaltigen Granulate, die die Besonderheit der erfindungsgemäßen Begasungsmittel sind, in der gewünschten Menge hinzugefügt.The basic raw material of the fumigants are wood flours of different provenance according to local availability. Flours of tropical hardwoods and coconut shells in various proportions give advantages both in production and in product quality. The wood flour can also be replaced by ground charcoal. This results in black products that do not require another dye. For the preparation of the mixture large belt or paddle mixers are used. The wood meals are also the active ingredient-containing granules, which are the peculiarity of the fumigant invention, added in the desired amount.
Häufig werden Coils, die normalerweise braun sind, durch Zugabe von Farbstoff gefärbt. Neben grünem Farbstoff wird auch vereinzelt roter Farbstoff verwendet.Frequently, coils that are usually brown are colored by the addition of dye. In addition to green dye also occasionally red dye is used.
Die Holzmehlmischung, Klebstoff und gegebenenfalls Farbe werden schließlich in einem Walzenmischer vereinigt und bis zur Erreichung der erforderlichen Homogenität und Konsistenz geknetet, gemischt und gewalzt. Die fertige Masse wird danach in einen Vorratsbehälter entleert, aus dem der folgende kontinuierlich arbeitende Band - Extruder gespeist wird.The wood flour mixture, adhesive and optionally color are finally combined in a roller mixer and kneaded until mixed to the required homogeneity and consistency, mixed and rolled. The finished mass is then emptied into a reservoir from which the following continuously operating belt extruder is fed.
Mittels Doppelwellen -Extrudern wird die Coilmasse bei höherer Temperatur zu einem ca. 5 mm dickem und bis zu 20 cm breiten und glatten Band extrudiert. Dieses Band wird in ca. 1,20 m lange Stücke geschnitten, die einer Stanzmaschine zugeführt werden. Stanzen in unterschiedlichen Mechanisierungsgraden sind im Einsatz.By means of double-shaft extruders, the coil mass is extruded at a higher temperature to form a strip which is approximately 5 mm thick and up to 20 cm wide and smooth. This volume will be about 1.20 m long Cut pieces that are fed to a punching machine. Punching in different degrees of mechanization are in use.
Die Trocknung der Produkte erfolgt beispielweise in der Weise, dass die ausgestanzten Produkte per Hand auf Drahtnetz - oder Lochblechhorden gelegt und diese auf Hordenwagen gestapelt werden. Zur Trocknung der Produkte werden diese Hordenwagen in Trockenräume gefahren und während 6 - 8 Stunden bei 60° - 700C getrocknet.The drying of the products takes place, for example, in such a way that the punched products are placed by hand on wire mesh or perforated metal trays and these are stacked on trolleys. To dry the products, these trolleys are moved into drying rooms and dried for 6 - 8 hours at 60 ° - 70 0 C.
Hochmechanisierte Betriebe betreiben kontinuierliche Trockner, die sich unmittelbar an die Stanzmaschinen anschließen und automatisch beschickt werden. Die Produkte liegen in kleineren Horden, die ihrerseits in 2 Endlosketten hängen und über mehrere Etagen durch den Ofen geführt werden. Die Öfen können bis zu 60 m lang und 8 m hoch und mit Endlosketten bis zu 600 m Länge bestückt sein. Die Trockentemperatur beträgt ebenfalls 60° - 700C und die Verweilzeit der Coils 3 - 4- Stunden.Highly mechanized companies operate continuous dryers, which connect directly to the punching machines and are fed automatically. The products are in smaller hordes, which in turn hang in 2 endless chains and are passed over several floors through the oven. The ovens can be up to 60 m long and 8 m high and equipped with endless chains up to 600 m in length. The drying temperature is also 60 ° - 70 0 C and the residence time of the coils 3 - 4 hours.
Die Trocknung der Coils ist beendet, wenn der Feuchtigkeitsgehalt 6 - 8 % beträgt.The drying of the coils is finished when the moisture content is 6 - 8%.
