The remainder ad 100 parts by weight of water.
Der erfindungsgemäß zu verwendende keimtötende Wirkstoff ist in derartigen Mitteln auch über einen längeren Zeitraum stabil und wird weder durch längere Lagerzeit noch durch die gleichzeitige Anwesenheit der übrigen BestanoU'.ile in seiner Wirkungsweise beeinträchtigt.The germicidal agent to be used according to the invention is also present in such agents Stable for a longer period of time and is neither due to longer storage times nor simultaneous presence of the rest of the BestanoU'.ile in its mode of action impaired.
Es wurde eine Lösung hergestellt, die im Liter 0,05 g 2-Brom-2-nitropropandiol-(l,3) und 21 g Zucker enthielten. In die Lösung wurden Rosen (,Bei ange«), deren Blattwerk bis zum höchsten Stand des Blumenwassers entfernt und deren Stiele direkt vor dem Einbringen schräg angeschnitten worden waren, eingestellt.A solution was prepared which contained 0.05 g of 2-bromo-2-nitropropanediol (1.3) and 21 g of sugar per liter. In the solution were roses ("Bei ange"), their foliage removed to the highest level of the flower water and their stalks just before introduction had been cut at an angle.
Blütenentfaltung und Haltbarkeit dieser Rosen \varen gegenüber solchen, die in Leitungswasser eingestellt worden waren, merklich verbessert (8 Tage gegenüber 5 Tagen Frischhaltung). Üuer den Beobachtungszeitraum konnten keinerlei Schäden an Blattwerk und Blüten festgestellt werden.Flowering and durability of these roses \ varen compared to those that are placed in tap water were noticeably improved (8 days compared to 5 days of freshness). About the observation period no damage to the foliage and flowers could be found.
Es wurde ein festes Mittel folgender Zusammensetzung hergestellt:A solid means of the following composition was made:
99,5 Gewichtsteile Dextrose,
0,25 Gewichtsteile 2-Brom-2-nitropropandiol-(l,3), 0,25 Gewichtsteile Borsäure.99.5 parts by weight of dextrose,
0.25 part by weight of 2-bromo-2-nitropropanediol- (1.3), 0.25 part by weight of boric acid.
In Lösungen, die jeweils 30 g dieses Mittels im Liter enthielten, wurden Chrysanthemen (Chrys. indicum) eingestellt, die, wie im Beispiel 1 beschrieben, vorbehandelt waren. Die Haltbarkeit von Blüten und Blättern der Proben war gegenüber solchen, die in Leitungswasser eingestellt waren, deutlich erhöht (17 Tage gegenüber 11 Tagen). Verfärbungen an Blüten und Blättern konnten im Beobachtungszeitraum nicht festgestellt werden.In solutions containing 30 g of this agent per liter contained, chrysanthemums (Chrys. indicum) were set, which, as described in Example 1, pretreated was. The shelf life of the flowers and leaves of the samples was compared to that of those in tap water were set, significantly increased (17 days versus 11 days). Discoloration on flowers and Leaves could not be determined during the observation period.
Es wurde ein flüssiges Mittel folgender Zusammensetzung hergestellt:A liquid agent of the following composition was produced:
55,55 Gewichtsteile Rohrzucker,55.55 parts by weight cane sugar,
0,666 Gewichtsteile Bernsteinsäure,0.666 parts by weight succinic acid,
0,333 Gewichtsteile AlCl3 · 6 H?O,0.333 parts by weight AlCl 3 · 6 H ? O,

The remainder ad 100 parts by weight of water.
Zu Vergleichszwecken wurden flüssige Mittel hergestellt, in denen bei im übrigen identischer Zusammensetzung das 2-Brom-2-nitropropandtol-(l,3) durch die gleiche Menge der folgenden antimikrobiell wirksamen Substanzen ersetzt worden war: Na-SaIz von p-Chlorm-krpsol, Sorbinsäure, Hexamethylentetramin, Formalin, Omazide 24® (Handelsprodukt der Fa. Olirt-Chemicals), öiamin A® (quart. Ammoniumsalz, Handels* orodukt der Fa. Bayer).For comparison purposes, liquid agents were produced in which the composition was otherwise identical the 2-bromo-2-nitropropandtol- (l, 3) by the the same amount of the following antimicrobial substances had been replaced: Na salt from p-Chlorm-krpsol, Sorbic acid, hexamethylenetetramine, formalin, Omazide 24® (commercial product from Olirt-Chemicals), Oiamin A® (quart. ammonium salt, commercial product from Bayer).
Jeweils 30 ml dieser flüssigen Mittel wurden mit 11 Wasser verdünnt und in die Lösungen Rosen (»Bei ange«), Chrysanthemen (chrys. indicum) und Nelken eingestellt, nachdem die Schnittblumen, wie im Bei-30 ml of each of these liquid agents were mixed with 11 Dilute water and add roses ("Bei ange"), chrysanthemums (chrys. Indicum) and carnations set after the cut flowers, as in
S spiel 1 beschrieben, vorbereitet worden waren. Während der eigentliche Verwelkungsprozeß bei allen Lösungen gegenüber Vergleichsversuchen mit Leitungswasser merklich verzögert wurde, blieben lediglich die in 2-Brom-2-nitropropandiol-(l,3) enthaltende Lösun-S game 1 described, had been prepared. During the actual withering process in all solutions was noticeably delayed compared to comparative tests with tap water, only the remained in 2-bromo-2-nitropropanediol- (l, 3) containing solution
o gen eingestellten Schnittblumen völlig frei von Blatt- und Blü'snschäden. In allen anderen Fällen traten nach 3 bis 6 Tagen je nach Pflanzenart mehr oder minder starke bräunliche Verfärbungen an Blättern und Blüten auf.o the cut flowers that have been set are completely free of leaf and flower damage. In all other cases more or more occurred after 3 to 6 days, depending on the type of plant less strong brownish discolouration on leaves and flowers.
Es wurden Lösungen hergestellt, die im Liter 17 g Zucker (schweizerische Patentschrift 181 737, Beispiele) und zusätzlichSolutions were prepared containing 17 g of sugar per liter (Swiss patent specification 181 737, examples) and additionally
1. 0,1 g Dimethylbenzyl-dodecylammoniumchlorid gemäß Beispiel 2 vorgenannter schweizer Patentschrift, 1. 0.1 g of dimethylbenzyl-dodecylammonium chloride according to Example 2 of the aforementioned Swiss patent,
