Description
Verfahren zur Bekämpfung von Pflanzenschädlingen. Das Nikotin :ist als wirksames Mittel zur Bekämpfung von Pflanzenschädlingen bekannt. Man hat, um die mit seiner Verwendung verbundenen hohen Kosten zu vermeiden, statt seiner auch Tabakbeize und -laugen benutzt, die jedoch bei wechselnder Zusammensetzung ungleichmäßig und keineswegs so stark wie :\iikotin wirken. Pyridin, welches man auch an Stelle von Nikotin zu verwenden suchte, eignet sich für die erwähnten Zwecke weit schlechter und stört durch seinen so unangenehmen Geruch.Methods of combating plant pests. The nicotine: is known as an effective means of combating plant pests. One has to avoid the high costs associated with its use, instead of it Tobacco stain and liquor used, but unevenly when the composition changes and by no means as strong as: \ iikotin act. Pyridine, which one also in place Tried to use nicotine is far less suitable for the purposes mentioned and annoying by its unpleasant smell.
Es wurde nun gefunden, daß die hydrierten Akridine sowie,ihre Derivate und Salze, technisch leicht zugängliche Verbindungen, ganz ausgezeichnet Parasiten aller Art abzutöten @-ermögen, ohne daß hierbei eine Schädigung der Pflanzen selbst eintritt. So vermögen z. B. (las Oktohydroakridin, auch in Form seines Chlorhydrates, oder das tetrahydroakridincarbonsaure Natrium bereits in kleinsten Menrien eine ausgezeichnete Wirkung auszuüben. Die Konzentration der zur Verwendung gelangenden Menge richtet sich hierbei ganz nach der Natur der zu bekämpfenden Schädlinge.It has now been found that the hydrogenated acridines as well as their derivatives and salts, technically easily accessible compounds, excellent parasites Kill all kinds without damaging the plants themselves entry. So manage z. B. (read octohydroacridine, also in the form of its chlorohydrate, or the tetrahydroacridine carboxylic acid sodium even in the smallest of quantities exert excellent effect. The concentration of those to be used The amount depends entirely on the nature of the pests to be controlled.
Die genannten Basen werden von Seifenlösungen aller Art äußerst leicht aufgenommen, und diese Lösungen bleiben bei weiterem Verdünnen mit Wasser klar, oder sie liefern gut haltbare Emulsionen. In dieser Form sind dne hydrierten Akridine ganz besonders wirksam. Verseift man z. B. Kolophonium in Gegenwart von Dimethyltetrahydroakridin, so erhält man eine klare Lösung, welche man vor dem Gebrauch mit Wasser verdünnt und alsdann in geeigneter Weise auf die zu schützenden Pflanzenteile bringt.The bases mentioned become extremely light with soap solutions of all kinds added, and these solutions remain clear on further dilution with water, or they provide emulsions with a long shelf life. In this form are the hydrogenated acridines particularly effective. Saponified z. B. rosin in the presence of dimethyltetrahydroacridine, this gives a clear solution which is diluted with water before use and then brings it to the parts of the plant to be protected in a suitable manner.
Die erwähnten Verbindungen entfalten auch im Gemisch mit anderen für die Schädlingsbekämpfung geeigneten Mitteln eine gute Wirkung.The mentioned compounds also develop in a mixture with others for the pest control agents have a good effect.
