Pflanzenschutzmittel.
Die insektizide und fungizide Wirkung des Schwefels und seine dieser Wirkung ent- sprechend Verwendung als Pflanzenschutzmittel ist seit langer Zeit allgemein bekannt. Insbesondere wurde der Schwefel zu diesem Zwecke in Form einer eigens zubereiteten Schwefelkalkbrühe oder künstlich hergestellter Mischungen von Sulfiden der Alkalien und Erdalkalien
EMI1.1
Es wurde nun gefunden, dass für den genannten Zweck die schwefelhaltigen Abwässer von der Fabrikation künstlicher Gebilde, wie Fasern, Bändchen, Häutchen, Films usw. aus Viskose. also insbesondere die schwefelhaltigen Abwässer der Viskosekunstseideindustrie und der Herstellung von Viskosefilms, geeignet sind.
Bei der Entschwefelung der Viskoseseide und Viskosefilms wird der überschüssige elementare Schwefel durch Bäder welche Natriumsulfid enthalten, entfernt und findet sich derselbe dann in den Abwässern als Polysulfid und feinst verteilter Schwefel vor. Diese Abwässer wurden bisher meist ungenutzt ablaufen gelassen. Der Vorteil der Verwendung dieser Abwässer als Pflanzenschutzmittel liegt auf der Hand. Es wird

auch die Fischzucht leidet, vermieden und ein bisher unbrauchbarer Abfall einer praktischen Ausnutzung zugeführt.
Die Anwendung der Abwässer hiebei kann direkt erfolgen oder, wenn zweckmässig, nach vorheriger Eindickung oder Trocknung zu eiuem festen Produkt. Auch können die Abwässer allen jenen sonstigen Massnahmen unterworfen werden, welche bisher bei der Herstellung solcher schwefelhaltiger Pflanzenschutzmittel üblich waren. Dieselben können mit anderen Pflanzenschutzmitteln organischer oder anorganischer Natur wie Tahakauszug, Kupfersalze, Zinksalze usw. vermischt werden. Auch können dieselben mit Stabilisatoren für die Polysulfide, wie z. B.
Zuckerarten, dann auch mit Mitteln wie Seife, Leim usw. versetzt werden. Desgleichen können die Abwässer mit Erdalkalien und deren Verbindungen behandelt werden.

Pesticides.
The insecticidal and fungicidal effect of sulfur and its use as a pesticide in accordance with this effect has been generally known for a long time. In particular, the sulfur was used for this purpose in the form of a specially prepared lime-sulfur broth or artificially produced mixtures of sulphides of alkalis and alkaline earths
EMI1.1
It has now been found that the sulfur-containing waste water from the manufacture of artificial structures such as fibers, ribbons, skins, films, etc. made of viscose can be used for the stated purpose. so in particular the sulfur-containing wastewater from the viscose rayon industry and the production of viscose film are suitable.
During the desulfurization of viscose silk and viscose film, the excess elemental sulfur is removed by baths containing sodium sulfide and is then found in the wastewater as polysulfide and finely divided sulfur. So far, this wastewater has mostly been allowed to run off unused. The advantage of using this waste water as a pesticide is obvious. It will
EMI1.2
Fish farming also suffers, is avoided and a previously unusable waste is put to practical use.
The wastewater can be used directly or, if appropriate, after prior thickening or drying to form a solid product. The wastewater can also be subjected to all those other measures that were previously common in the production of such sulfur-containing pesticides. These can be mixed with other pesticides of an organic or inorganic nature such as tahak extract, copper salts, zinc salts, etc. The same can also be used with stabilizers for the polysulfides, such as. B.
Types of sugar, then also with agents such as soap, glue, etc. Likewise, the wastewater can be treated with alkaline earths and their compounds.
