Description
Verfahren zur Bekämpfung von Pflanzenschädlingen. Die Bekämpfung von Pflanzenschädlingen mittels kolloidalen Schwefels geschah meist in der Weise, daß man kolloidale Schwefelpräparate herstellte, diese vor Gebrauch mit Wasser verdünnte und die derart erhaltenen wäßrigen Lösungen auf die Pflanzen auftrug.Methods of combating plant pests. The fight against Plant pests by means of colloidal sulfur usually happened in such a way that colloidal sulfur preparations were made and diluted with water before use and applying the aqueous solutions thus obtained to the plants.
Es wurde- nun ein wesentlich einfacheres und billigeres Verfahren gefunden, welches darin besteht, daß man die Bildung des fein verteilten Schwefels erst auf der Pflanze selbst sich vollziehen läßt. Dies wird in der Weise erreicht, daß man sie mit Lösungen von Thioschwefelsäure, die man kurz vor dem Gebrauch durch Zusatz von Säure zu Natriumthiosulfatlösungen erzeugt hat, besprengt.It became a much simpler and cheaper process found, which consists in the formation of the finely divided sulfur can only be carried out on the plant itself. This is achieved in the way that you can do it with solutions of thiosulphuric acid, which you just before use Addition of acid to sodium thiosulfate solutions has sprinkled.
Man hat bereits früher Desinfektionsmittel empfohlen, welche u. a. aus Mischungen von unterschwefligsauren Salzen mit Eisen, Mangan- usw. Salzen bestehen. Aus diesen Mischungen entsteht aber unter der Einwirkung der feuchten Atmosphäre kein Schwefel, sondern vorwiegend Tetrathionat. Außerdem eignen sie sich für den vorliegenden Zweck nicht, da eine Besprengung von Pflanzen mit derartigen Metallsalzen nicht angängig ist. Im Gegensatz hierzu erzielt man nach der neuen Arbeitsweise außerordentlich wirksame Lösungen von kolloidalern Schwefel, welche auf der Pflanze eine ausgezeichnete Wirkung hervorrufen, ohne daß sie irgendwelche Schädigungen hervorrufen. Beiispiel i.Disinfectants have been recommended in the past, including consist of mixtures of hyposulphurous salts with iron, manganese, etc. salts. From these mixtures, however, arises under the influence of the humid atmosphere no sulfur, but mainly tetrathionate. They are also suitable for the The present purpose is not because of the sprinkling of plants with such metal salts is not accessible. In contrast to this, one achieves according to the new working method extremely effective solutions of colloidal sulfur which are found on the plant produce an excellent effect without causing any damage cause. Example i.
Gibt man zu der verdünnten wäßrigen Lösung von 74 Teilen Natriumthiosulfat 0,43 1 einer 5prozentigen Salzsäure und bringt die Mischung sofort auf die zu besprengenden Pflanzenteile, so entsteht auf diesen ein Überzug von kolloidalern Schwefel.Is added to the dilute aqueous solution of 74 parts of sodium thiosulfate 0.43 1 of a 5 per cent hydrochloric acid and bring the mixture immediately to the besprengenden to parts of plants, so being built on these, a coating of kolloidalern sulfur.
Beispiel :2.Example: 2.
Will man bei der Herstellung der Lösungen Tabletten verwenden, so geht man von Tablettenpaaren aus, welche ?- Teile Natriumthiosulfat in der einen und i Teil Oxalsäure oder :2,1 Teile oxalsaures Natrium in der anderen Tablette enthalten. Man gibt diese Tabletten in Wasser und verfährt mit dieser Lösung in der oben angegebenen Weise.If you want to use tablets in the preparation of the solutions, so if one assumes pairs of tablets, which one? - parts of sodium thiosulphate in one and i part of oxalic acid or: 2.1 parts of sodium oxalate in the other tablet contain. You put these tablets in water and proceed with this solution in the way indicated above.
