Es wurde gefunden, daß die erfindungsgemäßen Verbindungen hervorragende insektizide Mittel sind, insbesondere in ihrer Dauerwirkung gegenüber Insekten. Sie sind wesentlich besser wirksam als strukturell sehr ähnlich gebaute bekannte Verbindungen. Beispielsweise wurde die Wirksamkeit des O,O-Dimethyl - O - 2,5 - dichlor - 4 - bromphenylthiophosphats (Substanz 2) gegen Hausfliegen vergleichend gegenüber der Wirksamkeit des bekannten 0,0-Dimethyl - O - 2,4,5 - trichlorphenylthiophosphats (Substanz 1) bei verschiedenen Konzentrationen getestet. Dabei wurden wäßrige Suspensionen der Wirkstoffe Insektizide MittelIt has been found that the compounds according to the invention are excellent insecticidal agents, especially in their long-term effect on insects. They are much more effective than structurally very similar known connections. For example, the effectiveness of the O, O-dimethyl - O - 2,5 - dichloro - 4 - bromophenyl thiophosphate (Substance 2) against house flies compared to the effectiveness of the known 0,0-dimethyl - O - 2,4,5 - trichlorophenylthiophosphate (substance 1) tested at different concentrations. Aqueous suspensions of the active ingredients were used as insecticidal agents

Neben der überlegenen Dauerwirkung der beanspruchten Wirkstoffe zeigen dieselben zusätzlich eine besonders geringe Toxizität gegenüber Warmblütern. Die LD50 (weiße Maus, ρ. ο.) liegt durchschnittlich über 2000 mg/kg.In addition to the superior long-term effect of the claimed active ingredients, they also show a particularly low toxicity to warm-blooded animals. The LD50 (white mouse, ρ. Ο.) Is average over 2000 mg / kg.

Die Anwendung der neuen Wirkstoffe erfolgt in der in der Schädlingsbekämpfung üblichen Weise. Die Wirkstoffe können für sich allein oder in Mischung mit anderen Wirkstoffen, z. B. in Form von Suspensionen, Lösungen, Streupulvern oder Pasten zur Anwendung gelangen. Die bevorzugte Wirkstoffkonzentration beträgt 0,01 bis 3%.The new active ingredients are used in the manner customary in pest control. the Active ingredients can be used alone or in a mixture with other active ingredients, e.g. B. in the form of suspensions, Solutions, powders or pastes are used. The preferred concentration of active ingredient is 0.01 to 3%.

Der O^-Dimethyl-O^S-dichlor^-bromphenylthiophosphorsäureester wird beispielsweise folgendermaßen hergestellt:The O ^ -Dimethyl-O ^ S-dichloro ^ -bromophenylthiophosphoric acid ester is made, for example, as follows:

272,9 g2,5-Dichlor-4-bromphenolnatrium (1,0MoI) werden in 700 ecm Chlorbenzol suspendiert und mit 176,6 g Ο,Ο-Dimethylthiophosphorsäurechlorid (1,1 Mol) versetzt und unter Rühren 8 Stunden auf 10O0C erhitzt. Dem Reaktionsansatz wurden 5 g Kaliumbromid als Katalysator hinzugefügt.272.9 g of 2,5-dichloro-4-bromophenol sodium (1.0 mol) are suspended in 700 ecm of chlorobenzene, and 176.6 g of Ο, Ο-dimethylthiophosphoric acid chloride (1.1 mol) are added and the mixture is kept at 10O 0 C for 8 hours with stirring heated. 5 g of potassium bromide were added as a catalyst to the reaction mixture.

Nach beendeter Umsetzung wird vom Kochsalz abfiltriert, die Lösung mit verdünnter Natronlauge gewaschen und anschließend mit Natriumsulfat getrocknet. Nach Abdestillieren des Chlorbenzols erhält man ein farbloses Öl.After the reaction has ended, the sodium chloride is filtered off and the solution is washed with dilute sodium hydroxide solution washed and then dried with sodium sulfate. Obtains after distilling off the chlorobenzene one colorless oil.
