Description

Gegenstand! des Hauptpatents 93&S75 ist ein Verfahren zur Bekämpfung von Schädlingen durch dem Boden zugesetzte Mittel, die aus mineralischen Düngemitteln im Gemisch mit Calciumcarbid oder solches enthaltendem Kalkstickstoff bestehen.Object! of the main patent 93 & S75 is a Method of combating pests by means of soil added means consisting of mineral Fertilizers mixed with calcium carbide or calcium cyanamide containing calcium carbide exist.

Die sich hierdurch entwickelnden Giftgase setzen jedoch wasserfreie Düngemittelmischungen voraus, damit nicht die Zersetzung des Oalciumoarbids vorzeitig erfolgt und damit die Giftwirkung auf die Schädlinge illusorisch wird.The toxic gases that develop as a result, however, require anhydrous fertilizer mixtures, thus not the decomposition of the oalcium carbide occurs prematurely and thus the poisonous effect on the pests becomes illusory.

Zur Erweiterung der Schädlingsbekämpfung nach diesem Verfahren in Kombination· mit mineralischen Düngemitteln können auch wasserhaltige Düngemittel zur Verwendung gelangen durch Abänderung des Verfahrens und der Mittel, indem zur1 Verwendung gelangende Giftgase nicht erst im Boden entwickelt werden, sondern vorher durch Adsorption an geeignete Mittel wie Kieselsäuregel, feinverteilte· Kieselsäure, gekörnte oder gepulverte Holzkohle, Tierkohle, Braunkohle, Torf oder Ruß gebunden werden.To expand the pest by this method in combination · with mineral fertilizers and water-containing fertilizers can come to use by modifying the method and means by are not designed for one use reaching toxic gases only in the ground but previously by adsorption to suitable means such as silica gel , finely divided silica, granulated or powdered charcoal, animal charcoal, lignite, peat or soot can be bound.

Diese Präparate können dann entweder direkt oder auch mit neutralen Mitteln, wie z.B. Sand,-verdünnt verwandt oder mit mineralischen: Düngemitteln! gemischt werden.These preparations can then either directly or diluted with neutral agents such as sand related or with mineral: fertilizers! be mixed.

In den Boden gebracht, werden sie dann durch die Bodenkohlensäure und Feuchtigkeit nach und nach aus dem Adsorption'szustand verdrängt. Von den Pflanzenwurzeln aufgenommen^ können sie ihre Giftwi'rkuog auf die Schädlinge ausüben. Die Bodenkohlensäure wirkt bei "Verwendung von Sulfiden, wie z. B. bei Schwefelcalcium oder Schwefelbarium, wenn diese als Zumischung dienen, unter Freimachung von Schwefelwasserstoff. Ausgeschlossen sind dabei saure Düngemittel, bei denen der Schwefelwasserstoff zu früh entbunden würde.Brought into the ground, they are then carried through the soil carbonic acid and moisture are gradually displaced from the state of adsorption. from absorbed by the plant roots, they can exert their poisonous effect on the pests. the Soil carbonic acid is effective when "sulfides are used, such as calcium sulfide or barium sulfide, if these serve as admixture, releasing hydrogen sulfide. Locked out are acidic fertilizers in which the hydrogen sulfide would be released too early.
