Description
Schädlingsbekämpfungsmittel. Die Verwendung von Schwefelkohlenstoff zur Bekämpfung von Schädlingen, insbesondere der Rehlaus, ist bekanlit. Bisher wird dieses Mittel in flüssiger Form für sich oder im Gemisch mit anderen Flüssigkeiten angewendet, und zwar wird. es entweder oberflächlich aufgebracht oder durch Bohrlöcher dem Boden zugeführt; dabei besteht die Gefahr einer Schädigung der Pflanze durch direkte Berührung mit der Flüssigkeit. Es ist auch der Vorschlag gemacht worden, den Schwefelkohlenstoff von Moostorf aufsatigen zu lassen und in dieser Form in den Boden zu bringen. Bei Verwendung des Moostorfes in loser Form ist aber die Verdampfungsgeschwindigkeit des Schwefelkohlenstoffes infolge der großen Oberfläche besonders groß, die Dauer der Wirksamkeit also sehr kurz.Pesticides. The use of carbon disulfide to control pests, especially the roe deer, is known. So far will this agent in liquid form on its own or in a mixture with other liquids applied, namely is. it is either applied superficially or through boreholes fed to the ground; there is a risk of damage to the plant direct contact with the liquid. The suggestion has also been made to let the carbon disulfide of Moostorf saturate and in this form in bring down the ground. When using the moss peat in loose form, however, the rate of evaporation is lower of carbon disulfide owing to the large surface especially large, the duration the effectiveness is very short.
Die-genannten Nachteile werden, wie gefunden wurde, weitgehend vermieden, wenn man mit Schwefelkohlenstoff beladenes aktiviertes, feinporöses Material, wie z. B. aktive Kohle, aktive Kieselsäure u. dgl., anwendet. Die Abgabe voll Schwefelkohlenstoffdampf ei-folgt verhältnismäßig langsam, so daß eine sehr nachhaltige Wirkung erzielt wird; eine Schädigung der Pflanze durch direkte Berührung mit flüssigem Schwefelkohlenstoff ist dabei ausgeschlossen. Das mit Schwefelkohlenstoff beladene Adsorptionsmittel läßt sich gleichmäß#ig und mit geringem Materialverlust verteilen.The disadvantages mentioned are largely avoided, as has been found, when activated, fine-pored material loaded with carbon disulfide, such as z. B. active charcoal, active silica and the like., Applies. The discharge full of carbon disulfide vapor ei-follows relatively slowly, so that a very lasting effect is achieved; damage to the plant through direct contact with liquid carbon disulfide is excluded. The adsorbent loaded with carbon disulfide can be distributed evenly and with little loss of material.
Gegenüber dem bekannten Verfahren, den Schwefelkohlenstoff vor seiner Verwendung als Insekticid mit Hilfe von Gelatine, Leim oder sonstigen# leimähnlichen Substanzen und Wasser in feste Form überzuführen, hat das vorliegende Verfahren den Vorzug weit k' ,größerer Billigkeit und Einfachheit der Handhabung sowie noch besserer und gleichmäßigerer Verteilbarkeit des Mittels im Boden.Compared to the known method, the carbon disulfide before his Use as an insecticide with the help of gelatine, glue or other # glue-like The present process has to convert substances and water into solid form the advantage of far k ', greater cheapness and ease of use as well as still better and more even distribution of the agent in the soil.
