Description

Bekämpfung von Wasserschädlingen Die Hauptpatentanmeldung F 18 509 IV a/451 betrifft Gastropoden-Bekämpfungsmittel, die 2-Oxybenzanilide bzw. deren O-Acylderivate enthalten, die mit mindestens 2 Kernhalogenatomen oder mit mindestens einer Nitrogruppe und mindestens einem Halogenatom neben gegebenenfalls weiteren Substituenten substituiert sind.Combating water pests The main patent application F 18 509 IV a / 451 relates to gastropod control agents, the 2-oxybenzanilides or their Contain O-acyl derivatives with at least 2 nuclear halogen atoms or with at least a nitro group and at least one halogen atom in addition to optionally others Substituents are substituted.

Es wurde nun gefunden, daß diese Verbindungen nicht nur zur Bekämpfung von Wasserschnecken geeignet sind, sondern auch zur Vernichtung anderer Wasserschädlinge, wie z. B. Algen, Schleim- und Wasserbakterien sowie Wasserpilzen, wie Leptomitus lacteus, angewandt werden können. Sie übertreffen hierin in ihrer Wirkung das Natriumpentachlorphenolat erheblich, wie aus dem Beispiel hervorgeht.It has now been found that these compounds are not only used to combat are suitable for water snails, but also for the destruction of other water pests, such as B. algae, slime and water bacteria and water mushrooms such as leptomitus lacteus. In terms of their effectiveness, they outperform sodium pentachlorophenolate significant, as can be seen from the example.

Die Substanzen sollen eingesetzt werden zur Sauberhaltung von Betriebswässern und Kreislaufwässern, die zu Kühlungszwecken u. dgl. verwendet werden, vornehmlich in der Papier-, Holz- und Kartonagenindustrie, sowie zur Sauberhaltung von Abwässern der Zucker- und Zellstoffindustrie usw. In allen Fällen handelt es sich um die Klärung von Wässern sowie um die Verhinderung des Bewuchses von stehenden und beweglichen Oberflächen. Beispiel Bei in Bechergläsern durchgeführten Versuchen mit Chlorophyceen und Sphaerotilus natans wurden folgende noch wirksame Grenzkonzentrationen ermittelt Chloro- Sphaerotilus phyceen natans mg/1 mgll Natriumpentachlorphenolat. . 50 50 2',5-Dichlor-4'-nitrosalicyl- anilid . . . . . . . . . . . . . . . . . . 0,8 0,8 bis 1,2 The substances are to be used to keep process water and circulating water clean, which are used for cooling purposes and the like, primarily in the paper, wood and cardboard industries, as well as to keep wastewater from the sugar and pulp industry, etc. In all cases, it is the clarification of water and the prevention of growth on stationary and moving surfaces. EXAMPLE In experiments carried out in beakers with Chlorophyceae and Sphaerotilus natans, the following still effective limit concentrations were determined Chloro- spherotilus phyceen natans mg / 1 possible Sodium pentachlorophenolate. . 50 50 2 ', 5-dichloro-4'-nitrosalicyl- anilide. . . . . . . . . . . . . . . . . . 0.8 0.8 to 1.2
